If this is the case, all you need to do is turn on your sprinklers and then press the pop-up riser on the sprinkler head down with your foot so that it is pushed all the way back down into the body. Then, pull up to release the pop-up riser.
Why won’t my sprinkler head pop up?
— When a sprinkler head is clogged with dirt or other debris, it will soon fail to rise completely out of the ground. — A leak in the water line can cause low water pressure and keep water from flowing to the sprinkler head. If water doesn’t reach the sprinkler head, then it won’t pop-up out of the ground.
How do you fix a sprinkler head that doesn’t pop up?
Press the pop-up riser on the sprinkler head down firmly, but gently, with your foot so that it is pushed all the way back down into the body (you may get wet doing this!) Then release it so it pops back up. Repeat this 4 or 5 times to loosen and flush out any sand grains caught between the riser and the cap.
How do you unstick a sprinkler head?
Lubricate the sprinkler head with spray lubricant if pushing it down with the water turned on had no effect. Spray the lubricant generously around the shaft and wait for it to soak for a minute. Then push and pull the head to loosen it.
What is a sprinkler riser?
Fire sprinkler riser is like a bridge between your water supply and the sprinkler pipes in your building. That’s where water gets onto the building for fire extinguishing purposes. In actual sense, sprinkler riser is the main component of the sprinkler system.
How do you raise a sprinkler valve box?

How do you fix a pop up sprinkler?
STEP 1: Inspect your risers and nozzles Clear the sprinkler surround with a trowel or sprinkler surround cutter. Inspect the sprinkler body for damage. Lift the sprinkler riser and inspect it for damage. Unscrew the old nozzle. Inspect the inside for debris or damage. Undo the filter basket and rinse it under the tap.
How do I fix low pressure on my sprinkler system?
If this is the only issue, the fix is simple: access your backflow valves and open them completely to improve your water pressure. Most backflow preventer devices have two pipes: one that is horizontal and one that is vertical.
Why are my sprinklers not getting enough pressure?
The most common cause of low water pressure in sprinklers is the backflow preventer valves not opening fully. Even if the handles are partially turned or only one of them is turned, this is enough to restrict the water flow, resulting in a low-pressure sprinkler and dried out plants.
How high should sprinkler heads be above ground?
The correct height for a sprinkler head is to have the top of sprinkler head just above the soil surface. No more than a quarter of an inch above the ground level. This lowers the tripping hazard, and a lawn mower can go past it without causing any damage.
Can sprinkler heads be adjusted?
Fortunately, adjusting a spray head is pretty simple, in most cases. At the top of most spray nozzles is a small screw that is used to adjust the head itself. Using a small screw driver, you’ll need to either tighten or loosen this adjustment screw to achieve your desired results.
How does a sprinkler riser work?
As a fire sprinkler discharges, water flows out of the pipe, or branch line, it’s connected to. When that happens, water moves through the system riser to refill the branch line. These changes in flow and pressure are monitored at the riser by electronic devices called water flow switches.
What is the difference between a sprinkler riser and standpipe?
A “wet” standpipe is filled with water and is pressurized at all times. A dry riser is a main vertical pipe intended to distribute water to multiple levels of a building or structure as a component of the fire suppression systems. The pipe is maintained empty of water.
What is a valve box riser?
Valve box risers eliminate the time and expense of breaking up old concrete to raise a valve box. To use‚ simply remove your valve box lid‚ insert the riser and place the lid into the riser. All risers accept standard 5-1/4″ lids used by popular box manufacturers‚ as well as new lids (sold separately).
Where should a sprinkler valve box be placed?
In newer lawn irrigation systems, the valves should be installed in valve boxes set into the earth. Often these are easily visible. In small yards, there is often a single valve box located near where the irrigation pipes enter the ground from the water source.
Why is my sprinkler not working?
One of the most common problems is a clogged nozzle. Other times the nozzle may be irreversibly damaged, so a new one is needed. If cleaning or replacing the nozzle doesn’t fix the problem, the next place to look is at the actual head. In these cases, your sprinklers might drip water instead of spraying it.
What causes low pressure in one zone of sprinklers?
Often when your sprinkler system was running fine, and then one zone began to lose water pressure, the culprit is a leak in the zone’s lines or a leak at a nozzle or two. Leaking nozzles won’t produce the same water pressure and need to be replaced, which is fairly simple.
How do you increase your water pressure?
Look on the main supply pipe near your water meter for a conical valve that has a bolt sticking out of the cone. To raise pressure, turn the bolt clockwise after loosening its locknut. Keep an eye on the gauge to make sure the pressure is within bounds, then retighten the locknut.
