The trenches will be relatively shallow, usually 6 to 12 inches deep, depending on your area’s freeze cycles and frost severity. The trench must also be deep enough to allow the sprinklers to retract underground to prevent breakage from lawn machines.

Also, How long can a sprinkler line be?
LENGTH OF RUN LIMITS: ½ inch tubing can run up to 200 linear ft. ¼ inch tubing should not exceed 19 ft in length. MAXIMUM FLOW CAPACITY: ½ tubing can handle a maximum of 240 GPH or 4 GPM.
Moreover, What size sprinkler line should I use?
For schedule 40 PVC, use 1/2-inch pipe for a 4 GPM system, 3/4-inch pipe for 8 GPMs, 1-inch pipe for 13 GPMs, 1 1/4-inch pipe for 22 GPMs, 1 1/2-inch pipe for 30 GPMs, and 2-inch pipe for 50 GPMs.
How many sprinklers can I put on a zone?
At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home’s water capacity was 10 GPM, you could place 3 heads per zone.
How do you find a hidden sprinkler valve?
1) Start in the Most Likely Places
- Probe the soil. Determine the irrigation valve area, and sift through the soil in that specific section of your property. …

Why is my sprinkler water pressure so low?
The most common cause of low water pressure in sprinklers is the backflow preventer valves not opening fully. There are two main pipes in your backflow preventer – one horizontal and one vertical. Each pipe has a handle that can be turned to run with the line or across to open the valve.
What causes a sprinkler valve to stay open?
Air Trapped in the Valve:
The valves may have air trapped in them. A small bubble of air becomes trapped in the tiny water ports of the valve, this stops the water from flowing through the port. Since the water flowing through the port is what holds the valve diaphragm closed, the valve stays open.
Why is my sprinkler valve leaking?
The most common reason leaks occur is that the rubber parts in the valve box have worn out. Water seeps freely through the system when the diaphragm seal breaks or debris is obstructing the valve from closing. … A broken or aging sprinkler valve diaphragm seal only gets worse over time.
Should sprinkler valves be open or closed?
Make sure the sprinkler valve is closed, unless it’s the valve farthest from the main water source. You’ll want to leave this valve open and remove the sprinkler nozzle to allow air to escape when you turn on the water.

How much area can a sprinkler cover?
For example for storage applications the standard sprinklers used in CMDA, ESFR, and CMSA range between 100-130 square feet of coverage per sprinkler head. In the case of the extended coverage heads the square footage can range between 144-196 square feet per sprinkler head.
What is the coverage area of a sprinkler?
