Do I need a pressure regulator for sprinklers?

Asked by: Jennifer Jackson

Who needs a pressure regulator? Most if not all, pressurized irrigation systems will require a pressure regulator. An exception to this would be if you are using a gravity system with very low pressure, or very low flow.

Where should a sprinkler pressure regulator be installed?

On your drip zone.

What is the function of a pressure regulator installed on a sprinkler?

Pressure regulators are the unsung heroes of your irrigation system. These devices exist to maintain the system’s desired performance. They control excessive inlet pressure and assure you have a consistent outlet pressure running through your sprinklers.

When should you use a pressure regulator?

For example, pressure regulators are used in gas grills to regulate propane, in home heating furnaces to regulate natural gases, in medical and dental equipment to regulate oxygen and anesthesia gases, in pneumatic automation systems to regulate compressed air, in engines to regulate fuel and in fuel cells to regulate

What pressure do sprinklers need?

around 30 psi

Water pressure is measured in pounds per square inch – also called psi. The average water pressure for most homes and businesses is between 30 psi and 50 psi; most sprinkler systems are designed to use pressures of around 30 psi.

Does the pressure regulator go before or after the timer?

If you are using a timer, timer must be installed first, followed by the backflow preventer, the filter, and then the pressure regulator. Also, remember to hand tighten these parts.

How much pressure do pop up sprinklers need?

For a fixed spray system, aim for 20-30 psi per sprinkler. On a rotor/pop-up system, shoot for 30-60 psi. Irrigation and drip systems require 20-40 psi.

How do I adjust the water pressure on my sprinkler system?

To increase the flow turn the stem counterclockwise. In an emergency you can turn off the sprinklers from any particular valve by turning the valves flow control stem clockwise. Until it's hand tight.

Why do I need a pressure regulator for drip irrigation?

In short – no, pressure regulators are not optional in a drip irrigation system. Pressure regulators help prevent leaks, emitter blowouts, premature system damage, and irregular water application. If you want your irrigation system working fully, you need a pressure regulator.

Is 60 psi good water pressure for sprinkler system?

Most residential water pressures are generally in the 40 – 80 PSI range. Under 40 is considered low, so you may need to boost pressure if installing an irrigation system. Over 80 is high, and many household water appliances may be at risk of damage over this range. A pressure reducing valve may be necessary.

What causes sprinkler heads to not pop up all the way?

If you’re noticing that your sprinkler heads aren’t popping up and engaging, it’s, again, a water pressure issue. Most heads require a specific minimum amount of PSI of water pressure to engage. If you have a completely busted sprinkler head and don’t notice it, then your system will suffer for who knows how long.

How do I check my sprinkler psi?

The best place to start checking your pressure is the first hose bib you have in your front yard that comes off of the main line your water main line from the street you use a pressure gauge.
