Compressed Air thru valve

I installed a PVC 3/4 x 3/4 x 1/2 tee near my water source. I put a 1/2 PVC plug in it for regular use and remove it to thread in air connector for compressor. Question is I manually open the valves one at a time and applied 120psi compressed air. The valves sounded like french horns on crack. The valves are the Toro 1 inch backflow breakover type. Will this hurt the valves? Guess I will find out next summer huh?

That is fairly normal for the anti siphon type valves to make that noise...HOWEVER...I would caution you as to that high of pressure. You really want lower pressure and higher CFM...cubic feet (of air) per minute...

This can only be achieved by using a larger can rent them at the rental yard next year.

Good luck...
