What kind of compressor do I need to blow out sprinklers?
Beside this, what PSI is needed to blow out sprinklers?
Set the compressor air pressure regulator to a maximum of 80 psi for rigid PVC pipe systems, or 50 psi for flexible black polyethylene pipe. Then turn off the water supply and set the system timer to open just one zone. Next, open the manual drain valve at the end of that zone (if equipped).
One may also ask, can a pancake compressor blow out sprinklers? So a pancake or shopvac might be able to push water out of the system, but that doesn't mean it's getting all the water out, or even enough to prevent ice damage if the remaining water collects in a low spot. Fire sprinkler or lawn sprinkler? 10 cfm times 0.5 minute = 5 cfm - it's quite underpowered.
Regarding this, how do you blow out a sprinkler system with an air compressor?
To start the blow out, shut off the irrigation water supply and, with the compressor valve in the closed position, attach the air compressor hose to the fitting. Activate the station on the controller that is the zone or sprinklers highest in elevation and the furthest from the compressor.
How many CFM do I need to winterize my irrigation system?
To obtain proper air volume, you will need to rent or buy a compressor capable of providing 20 to 25 cubic feet per minute (CFM) of air volume. Air pressure must not exceed 50 pounds per square inch (psi) during the blow out procedure. A pressure-regulating valve must be used to avoid over pressurization of the system.
