As a licensed CSI, I found many problems with this video. For starters a licensed plumber should be performing the installation of the backflow assembly, and a licensed bpat person should test the device upon installation and annually thereafter with copy of test reports being submitted to your water utility provider, I wouldn’t use galvanized pipe for water lines due to rapid corrosion rates, your rpz assembly is also installed improperly being turned sideways. Also if this is just for a residential irrigation system, I wonder why your utility provider called for the more expensive rpz assembly when a double check valve assembly would have served the purpose and been more economic.
Man, try to never, ever thread metal into PVC. It’ll crack and leak. Male pvc nipples into female threads whenever you can.
They can be installed sideways but not the one in this video. It's a rp and should be upright and not sideways. On centain double check assemblys in ground they have to be sideways to access the 2nd check for repair. Good job piping it together and what u have will work fine. I see worse every day trust me. Good job
I have this video a thumbs down because your using galvanized pipe, which is cancer for irrigation. They rust and corrode causing issues with your backflow, your control valves and clogs nozzles. Also galvanized unions swell from corrosion and are an issues removing and resealing. I would prefer you remove this video because it's giving bad advise. I'm an irrigation professional and been doing it for almost 10 years. If you would of done this in sch 80 pipe, copper or even brass would of worked but galvanized is horrible.
this is all wrong, the test cocks should be facing upright, and you should be using brass nipples and elbow because the backflow is brass itself, and make sure you hire a certified tester after install, is the law.
Lmao..he’s wearing gloves.
So what did you do to hide the piping and preventer? Plants to cover it or a box of some sort?
Do you have a video showing how the main supply line is plumbed in or off a faucet?
This is the video I was looking for! Thank you!
