3 Reasons Why You Need Sprinkler Master Repair (Salt Lake City, UT)

It’s common to not trust a company when you think you can do the work on your own.

Tips and Tricks to a healthy lawn with Sprinkler Master Repair (Salt Lake City, UT)

As human beings, we always seek for ways to improve. The same can be said for your lawn. At Sprinkler Master Repair (Salt Lake City, UT) we recognize that your lawn is the outdoor centerpiece of your home. Taking care of it matters, and we are here to help you in making it look great! There are always improvements to be made. Perhaps a few blades of grass aren’t evenly cut, or that brown or yellow spot in the corner of your lawn just won’t go away, or perhaps you are over or under-watering your lawn altogether? Here are a few helpful tips to make any healthy lawn, healthier!

Aerate Your Lawn

Just like humans need air to breathe, so does your lawn! Lawn aeration simply means punching three inch deep holes evenly across your lawn, so your soil can breathe and generate proper nutrients. There are several different ways to aerate your lawn, either by renting a large aerating machine or by using a simple handheld aerating tool. For most homeowners with small to medium sized lawns, a handheld aerating tool, such as this, will make things work great. As a best practice, you should only need to aerate your lawn once a year, typically in the spring time.

Water Your LawnSprinkler Master Repair (Salt Lake City, UT) Fun

Sprinkler System Checklist for Salt Lake City Homebuyers

Purchasing a new home is a stressful experience and the technicians at Sprinkler Master Salt Lake City want to help relieve some of your stress. Among all the things you have to worry about with a new home is whether or not your sprinkler system works the way it should. We have created a sprinkler system checklist to help Salt Lake home buyers easily notice if there are problems in their system. 


There are 4 main issues that we run into at Sprinkler Master Salt Lake. They are; leaky sprinkler pipes, broken sprinkler heads, sprinkler heads that need to be adjusted, and faulty sprinkler zones. 


  1. Leaks

The most common signs that there is a leak in your sprinkler system are puddles of water forming on your lawn or low water pressure to your sprinkler heads. If you see pools of water after running the system or if your sprinklers don’t seem to be spraying as far as they should, there’s a good chance you have a leak. Leaks in your sprinkler line can cost you a lot of money if they aren’t taken care of quickly so call Sprinkler Master Salt Lake as soon as you can if you think you have a leak.

  1. Broken Sprinkler heads

Broken sprinkler heads are usually pretty easy to spot. Often times they look like a geyser, are stuck spraying in only one direction or don’t even pop up at all. Just like leaks, broken sprinkler heads waste water and can cost a lot if they aren’t fixed quickly.


  1. Heads that need adjusting

Sometimes all your sprinkler system needs is a little adjustment. If you notice dry spots or if your sprinklers are spraying on the driveway, sidewalk, shed, or anything else that doesn’t need to be watered give our Salt Lake technicians a call to get them adjusted properly. 


  1. Faulty zones

When you turn on your sprinkler system your zones should run in their assigned order like normal. You will know if you have a faulty sprinkler zone if one or more of the zones won’t turn on or don’t turn off when they are supposed to. Issues like this usually occur due to bad solenoids or broken sprinkler valves. Here at Sprinkler Master Salt Lake we have a lot of experience replacing and repairing sprinkler solenoids and valves and can quickly solve your problem!Remember, if you encounter any of these problems in your new Salt Lake home give Sprinkler Master Salt Lake City a call at 385-226-5764!

Five Highly Effective Sprinkler System Watering Tips

A healthy, green lawn needs about 1 – 1 1/12 inches of water per week. The best, most effective way to get your lawn the water it needs is to use a sprinkler system. A working sprinkler system will save you time, water, and money. A good test of your watering levels is to stick a six-inch screwdriver into your grass. If you cannot get the full length of the screwdriver into the ground, you are not watering enough. Below are five of our effective watering tips.

  1. Install a smart watering timer – A smart timer can save you time, water, and money by watering your lawn with the exact amount of water it needs. No more, no less. Our recommended smart timer is Skydrop, a local company with an innovative timer design. If you’d like us to install a Skydrop timer for you, give us a call!
  2. Water deeply 2-3 times a week instead of daily – This will require your grass to develop a long root system, making it stronger and healthier.
  3. Water early in the morning – Watering in the heat of the day will cause some of the water to evaporate, thus wasting precious water. If you water in the mornings, less evaporation will occur, thus effectively using as little water as possible.
  4. Install a rain or moisture sensor – A rain or moisture sensor can shut off your sprinkler system when it is not needed due to weather, and save you from wasting water.
  5. Check your sprinkler system routinely – Insuring that your system is fully functioning is incredibly important. If there are any problems with your system, it can cause dry spots and ruin the look of your beautiful lawn. If you need a repair done on your system, we can help! Contact us!

And remember, a broken sprinkler is a huge waste of water. You could lose hundreds of gallons from just one broken sprinkler1. If you have a busted sprinkler, don’t hesitate to call us! Contact us here: https://saltlake.utahsprinklermaster.repair/contact-us/

Sprinkler Repair Tips

Sprinkler heads not working? Solution 1: Replace the heads

Broken sprinkler heads are easy to identify. Simply look for cracked or broken plastic casing on the heads, heads that don’t pop up, or water that sprays wildly or not at all. It’s common to find the top of the head completely broken off. This typically happens to heads that are set too high and are run over by vehicles or hit by lawn mowers.

Replacing the head is one of the simplest fixes. Replacement heads are available at home centers and online. Be sure to buy the same type of head that you’re replacing.

To change a broken head, turn off the system and dig a 2-ft.-diameter hole around the head. Using a square shovel, slice the sod into easy-to-remove pieces. Set the sod on a tarp so you can set it back into place at the end of the job.

Dig down to the “riser” (the vertical pipe that branches off the main line) which is connected to the sprinkler head. Dig with a light touch to avoid damaging the plastic water line, which is 8 to 12 in. underground.

Turn the head counterclockwise to remove it from the riser. While the head is off, take care not to spill dirt into the riser. Sprinkler heads are installed only hand-tight, but after being in the ground for several years, they may require the use of wrenches to unscrew. If the head doesn’t turn easily, hold the riser with slip joint pliers to keep it from twisting loose from the fittings below.

Attach the new sprinkler head by placing it on the riser and turning it hand-tight (photo). Don’t use Teflon tape or joint compound on the riser threads. Sprinkler heads are factory tested to make sure they work. As a result, they’re often packaged still wet, so don’t be surprised to see water in a new head.

Before filling in the hole and replacing the sod, set the desired sprinkler pattern (see “Reset the Spray Pattern,” below).

Caution: Before you start digging to access the underground water lines, electrical wires or spray heads, dial 811 to have your underground utility lines identified and marked.

Sprinkler heads not working? Solution 2: Clean and reset heads

Dirt sometimes gets inside sprinkler heads, causing them to clog up. Clogged heads may rise but fail to spray, not lower after watering, or produce an erratic spray pattern.

To clean the head, dig it out and remove it from the Riser (Photo above). Take the head apart by holding the bottom of the canister and turning the top of the head counterclockwise. Once it’s unscrewed, lift it out of the canister (Photo 1).

Remove the plastic screen basket, which serves as a filter, at the base of the head. If you can’t pop the basket out with your fingers, pry it out with a flat-head screwdriver or pull it free with a pliers. Rinse the basket in a bucket of clean water, washing out the debris (Photo 2). Clean the rest of the sprinkler head by rinsing it with water. Replace the head on the riser. If it still doesn’t work, replace it with a new head. Note: In areas of the country that experience freezing temperatures, polyethylene (poly) pipe is used for the irrigation water lines. PVC pipe is used in areas that don’t freeze.

Reset the spray pattern

When putting on a new sprinkler head or using the same head after cleaning, you may need to adjust it to water a specific area. Adjustment methods vary. You can adjust some head types by turning a slot at the top with a screwdriver. Others require a special key that you insert into the head and turn (Photo 3). Some heads also allow you to adjust the spray pattern by turning a tiny screw located next to the nozzle.

Adjust the heads before installing them, then fine-tune them once they’re in place with the sprinkler running. First, turn the top clockwise until it stops. That nozzle location is the starting point (the head will turn counterclockwise from there). Adjust the head to set the watering rotation anywhere from 40 degrees to 360 degrees counterclockwise from the starting point. Set the head in the canister. Standing behind the head, align the nozzle with the right edge of the area you want to water, such as along a driveway. Tighten the head in the canister. Carefully backfill the hole and replace the sod.

Turn on the sprinklers at the controller. Allow the head to make a few rotations, then make additional adjustments while the system is running.

Low water pressure? Solution 1: Turn on valves at backflow device

Low water pressure will result in the sprinkler heads barely shooting water. In extreme cases, many of the heads won’t even pop up. Start with the easiest solution. Make sure the valves at the backflow device are fully open. The backflow device is located above ground, with the valve at least 12 in. above the highest sprinkler head in the yard. Most backflow devices have a valve on the horizontal and vertical pipes. Turn the valves to their open positions as shown. The valve is open when the handle is parallel with the pipe.

Low water pressure? Solution 2: Find and repair leaks

Then check for leaks in the water line. Look for a series of sprinkler heads that aren’t watering properly. The water line problem is always located between the last working head and the first nonworking head.

Look for signs of leaking water, such as water bubbling up from the soil when the sprinklers are running, a depression in the ground, or a very wet area. If you find running water, follow the water to the highest point to find the source.

Once you locate the approximate leak site, dig straight down to the water line. Then enlarge the hole along the line, following the flow of the leaking water until you find the break or crack. Before making the repair, make sure the system is turned off at the controller.

Use a slip coupling to repair the leak. This special coupling contracts to make insertion easy. Find these couplings and other repair parts at irrigation supply stores.

To fix the leak, use a hacksaw to cut out a 4-in. section of line at the leak. Place a clamp on one of the line ends, insert the coupling, then tighten the clamp.

Place a clamp on the second pipe end, expand the coupling while inserting the nipple into the pipe, then tighten the clamp. Backfill the hole with dirt and replace the sod.

Low water pressure? Solution 3: Repair crushed pipes

If you can’t locate a leak, the water line may be crushed or obstructed. Sometimes, roots wrap around the line and squeeze it closed over the course of several years (photo 1). Or vehicles may have compressed the soil and collapsed the line. These problems are harder to find and often require a lot of digging. Again, look for the problem after the last working head. Dig along the water line until you find the damaged section. If the line runs near a tree, start your digging there.

Once you locate the damaged section, cut it out with a hacksaw. If the line was damaged by tree roots, reroute the line by digging a new trench away from the tree.

Cut a new section of pipe to replace the damaged one. Then replace the section of pipe, connecting it at each end with regular couplings and band clamps (photo 2).

Zone not working? Solution 1: Check for voltage to the bad zone

Your watering system is divided into a series of zones. Each zone has an electrically activated valve that controls the heads for a designated area.

Generally, if you have a zone that’s not turning on, you have an electrical problem. To solve the problem, make sure the zone wires are firmly attached to the terminals in the controller, the transformer is plugged in, and the circuit breaker at the main panel is on.

Next, test for voltage to the non working zone, using a multimeter (at home centers and hardware stores). Turn on the nonworking zone at the controller. Turn the multimeter dial to voltage and place one lead on the common terminal (marked “c” or “com”). Place the other lead on the terminal of the zone that’s not working (photo left). It doesn’t matter which lead goes to which terminal.

Refer to your owner’s manual to see whether the voltage reading falls within the required range (usually 24 to 28 volts). If it doesn’t, the controller needs to be replaced. (If you don’t get any voltage reading, see “Check Fuse and Transformer,” below.)

Fortunately, controllers rarely go bad unless struck by lightning. New ones start at $175 and can cost upward of $400. Replace a damaged controller with the same brand and model as you currently have. To replace it, label each wire that’s connected to the controller with a piece of tape. Unhook the wires, then attach them to the new controller in the same sequence.

Zone not working? Solution 2: Check fuse and transformer

If no zones will turn on, first turn the controller to the manual setting to see if the system will run. If it turns on manually, the controller is good but the rain sensor may be stopping the automatic programmed watering, which is what it’s designed to do.

Rain sensors conserve water by preventing the system from running when the ground is already saturated and doesn’t need additional watering. Some states require rain sensors on all new systems. (Your rain sensor is bad if the system runs when the ground is already wet.)

If the system doesn’t run in the manual position, check the controller for power. If it has a fuse, make sure it’s not blown. Or, if it has a circuit breaker reset button, press the button, then try the system again. If the system is plugged into a GFCI receptacle, press the GFCI reset button.

If it still doesn’t turn on, make sure the outlet that the power transformer is plugged into is working by plugging in a power tool. If it’s working, plug the transformer back in, turn the system off and test the transformer for voltage. Using a multimeter, place a lead on each of the two transformer terminals. It doesn’t matter which lead goes to which terminal.

The transformer terminals are marked “24 vac.” A 24-voltage transformer should normally test between 24 and 28 volts. If the voltage falls below the manufacturer’s range, replace the transformer. Simply unscrew the terminals that hold the two transformer wires in the controller and remove the transformer (photo). Insert the wires on the new transformer through the designated opening in the controller. Attach the wires to the controller terminals marked “24 vac” by placing the wire ends under the screws, then tightening them.

Zone not working? Solution 3: Replace defective valve

If the controller, fuse and transformer check out OK, test the resistance “ohms” between the common terminal and the non working zone. Turn off the system, turn the multimeter to test for ohms (the omega symbol), and place the leads on the common terminal and zone terminal, just as you did to test for voltage.

Compare the ohms reading with the range listed in your owner’s manual (usually 20 to 60 ohms). If the ohms fall below the required amount, the switch (solenoid) that operates the control valve for that zone is defective and needs to be replaced. The defective solenoid will be connected to the same color wire as the zone wire at the controller. (If the reading is too high, see “Repair Damaged Wires” below.)

Control valves are typically grouped with three to six valves in one box (Photo 1). The boxes are located in the ground with a cover that simply lifts off. They can be located anywhere in the yard but are usually close to the main water supply.

Although valves themselves rarely need to be replaced, solenoids do occasionally fail. Replacing them is quick and easy. Be sure the controller is in the off position (you don’t need to shut off the power) and the water valves on the backflow device are turned off. Inside the control valve box, remove the wire connectors and disconnect the two wires on the defective solenoid from the common and field wires. Turn the solenoid counterclockwise to unscrew it from the valve (Photo 1). Water will slowly seep out of the valve opening, even with the water turned off.

Place a new solenoid in the valve and turn it until it’s finger-tight. Twist the ends of the new solenoid wires onto the same common and field wires that the old solenoid was attached to (Photo 2). It doesn’t matter which solenoid wire goes to the common and which one goes to the field wire. Twist a new waterproof wire connector over each connection (Photo 2). To make waterproof connections, use a silicone-filled “direct bury” connector (Photo 2A), available at home centers.

Repair damaged wires If the ohms reading between the common terminal and non working zone terminal is too high (it’s sometimes an infinity reading), the problem is a severed or bad wire to the control valve. If only one zone isn’t working, the field wire is damaged. If none of the zones in a control valve box is working, the common wire is damaged, although the field wires could also be bad.

To find a bad wire, bypass each in turn by temporarily substituting a 14-gauge wire for the original that you run above ground. Make the wire connections with the controller turned off. Then turn the controller back on. Test the field wire first. If the zone turns on, the old field wire is bad. Replace it with an 18-gauge wire rated for underground burial. Bury the wire at least 8 in. underground. Follow the same procedure to test the common wire.

Replacing Broken Sprinkler Heads

It’s easy to run over a sprinkler head with a lawn mower or set sprinkler water pressure too high, which makes broken sprinkler heads a common source of irrigation frustration. If your sprinkler heads have broken casings, won’t pop up all the way, and/or have inconsistent or nonexistent spray patterns, you may need to replace them.

When looking for replacement sprinkler heads, it is important to match the brand of the sprinkler system you have installed. For instance, Dr. Sprinkler Repair works exclusively with Rain Bird products for installations, so any replacement parts our expert sprinkler technicians purchase will be Rain Bird products as well. Purchasing the same brand as the original parts allows for a seamless transition to a working lawn irrigation system.

Prior to replacing a sprinkler head, be sure to shut off the water sprinkler system. Next, dig a hole (approximately two feet in diameter) around the broken sprinkler head. Make sure to save the dirt in order to fill in the hole later! Be careful not to damage the irrigation sprinkler pipes, as that will require a much bigger fix. Dig down 8 to 12 inches to the base of the sprinkler’s vertical pipe, also known as the “riser,” in order to expose all of the pieces that will be replaced.

Carefully twist the old sprinkler head in a counterclockwise fashion to remove it from the vertical pipe, so that you don’t get soil in the pipe (this could cause a blockage in the water line and potentially damage the new sprinkler head). If the years of use have caused the sprinkler head to become stuck in place, a wrench may be needed to loosen it. Hold the riser in place while using a wrench to avoid tearing the rest of the irrigation pipes out of place.

Install the new sprinkler head by twisting it into place with a clockwise motion (no need for a wrench – hand-tight will be just fine). Set the spray pattern according to the directions that accompanied the purchase of the new sprinkler head, then replace the sod that you removed from the hole previously.

Repairing a Defective Sprinkler Zone

Lawn irrigation systems are organized into several zones, or valves – this acts as a failsafe of sorts for your system. If one sprinkler zone becomes defective, the whole system is not necessarily compromised, which can save you a lot of time and money. Each sprinkler valve has its own electrical valves for the sprinkler heads in that area, so if an individual zone is not working, that is a good place to start looking for the source of the problem.

Check all wiring in the sprinkler zone for stable and secure connections. Next, check to see that the transformer is plugged in and working. Then look at the circuit breaker to be sure that the main panel is on and working. If none of those appear to be malfunctioning, it may be best to test the voltage to the sprinkler zone using a multimeter, a device available at most local hardware stores and home centers. Turn on the broken sprinkler valve from the controller and measure the voltage to see if it falls within your systems recommended range (which can be found in the sprinkler system’s owner’s manual.

If it does not fall within that range, the controller may need to be replaced. If maintained properly, sprinkler controllers do not often break unless they are struck by lightning, but this has been known to happen. New controllers vary in price from about $175 to $400. When looking for a replacement controller, be sure to purchase the exact same model as was previously installed.
