SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

I replaced the broken gate valves with ball valves, wasn't fun but they work now. Desoldering and resoldering 1" copper is tedious. Tip for anyone who needs to do this: try to figure out if you can desolder only one side and have enough room to disassemble the unit up to the next solder joint this will save time and hassle it worked for me. By the way the company that blew off the sprinkler head said they would not replace it they claim "if it blew off it must have been faulty". Thanks for all the advice. Next step trouble shooting stuck open valve and relocating sprinkler heads.

Must be a fly by night company. Thats alright though, because in this business, a lot of referrals and work comes by word of mouth, so it will get out eventually that this company has a poor reputation and is inexperienced, and they will suffer.

This is a very old thread...but it helped me startup the 765 PVB in my sprinkler system
I did not know the correct sequence and thought the Bonnet\Poppet setup was broken.
After reading mrwettech's post I was able to startup the sprinkler without any issues.
Thanks mrwettech!!
