It was already mentioned, but I just want to repeat it. Be carefull!! At 30 psi, if the clamp on the PVC adapter you are using doesn't hold, that PVC piece is coming out with an amazing amount of force. Make sure you, and anyone else in the area, is clear of it. I've put a heavy tarp over it to help dampen it if it comes out. I've had them come out at much lower pressures and I will definitely cause you to pucker...
