Ordered two, One would not even let water through it. It was a factory defect and Sprinkler warehouse would not replace it.

I have a Hendrickson PR55-20pp and it squirts water out a little hole on the side, is it broken?
Colin C on Mar 26, 2017
BEST ANSWER: That is part of the mechanism for pressure regulation, this should slow down significantly once the appropriate pressure has been reached in the line. But when you first turn the water on it will always drip
I have only 2 sprinkler heads to a small flower bed. Psi is 50 do I need a regulator on this?
