How much psi do you need for sprinklers?

Water pressure, measured in pounds per square inch (psi), is an essential factor to consider for homes, businesses, and sprinkler systems. Typically, the average water pressure for most residential and commercial properties falls within the range of 30 psi to 50 psi. This range ensures efficient water flow and usage. Specifically, sprinkler systems are designed to operate optimally at around 30 psi.

How do you drain sprinklers without an air compressor?

If your sprinkler system has irrigation lines that are buried with a slight downhill slope, you can winterize it without using an air compressor. This means you don’t have to blow the water out of the system. To do this, start by shutting off the main water supply to your system. Then, open the drain valves at the end of each zone. This will allow the water to naturally drain out of the system, preventing any potential damage caused by freezing temperatures.
