Just wondering if any of you could spot a problem with this set-up?
What would you have differently?
Ahh, its not level.
Hose bib before backflow is against code.
The fact that the line goes down and them back up to the backflow makes me thing there are valves or other goodies before the backflow.
Why did they use a doublecheck but suspend it in the air like an RPZ? Doublechecks can and should be buried.
Unless it is a RPZ, but it sure looks like a Febco doublecheck to me, I can't see a relief valve from that angle. Some municipalities frown about unions on backflows, especially in a warm climate like CA where you don't need to remove them for the winter.
Looks like crap too.
Pick up your flushcaps
Yes, it does look like a DCVA, what a dumb s..t install.
Relief is on the bottom of a Watts 009 ~ the concrete next to the foundation makes for a clumsy install. If there was a spot closer in, where the pipe could drop into the ground, I'd do things much differently.
'Hose bib before backflow' is kind of irrelevant. Nothing in that photo establishes anything upstream of the RPZ as sprinkler-system-only plumbing, and no one need torture themselves trying to infer any such thing. It would be more to the point to say what one's local inspector would claim as a violation. (and we all know inspector opinions/declarations and actual code are not one and the same)
Jon, hose bib BEFORE double-check is o.k. as long as you don't hook-up drip
or other stuff. Standard lawn sprinklers provide the air-gap. sequim guy?
I used to be from Sequim, I relocated a few months back. Did irrigation there for a while.
Hose Bibs before backflow is most certianly a no-no for most codes. I know its not a big deal in WA, but GusBuster is in CA, and they are anal about stuff like that.
Out here you can't even install regular hosebibs on the sides of houses anymore, you have to use one with a built in atmospheric breaker.
Jon, My H.D. Fowler guy, David, had told me about you being one of a VERRY
few folk who had the passsion and knowledge. Sorry to hear you've left the
biz......you'll be back; once you've got the fever, hard to let go.
What if the house is plumbed with a line exiting the structure, to a tee with two threaded outlets, and one of them is plugged, and the other has a hose bib. None of it is 'sprinkler system plumbing' - all you have is a plug and a hose bib. Make it a vacuum-breaker hose bib if you want. Now show me the code violation. There is no sprinkler system, so lose that section of any code you want to point at.
David's a great guy.
And he is right, in Sequim, and I won't say names, but we were the only company in that area that was at all competent that dealt with him.
I work in an office now. I've got a install lined up for my uncle in april, so I'll get my fix then
