New plumbing pressure

[alex800]

We had plumbing installed for our new pool yesterday and when the crew left the pressure gauge was showing 55 psi. This morning the pressure gauge showing 22 psi. Is this normal?

I'm not sure what the industry standard is for overnight loss if any. @jimmythegreek do you know?

Following so I know when we get to that part

 

[alex800]

Still going down. Now at 18 psi...

It should not lose pressure.

You can get some minor pressure change due to a temperature change, but it's not a lot.

 

[alex800]

That's what I was afraid of. Plumbing inspection is scheduled for today. Wonder if they will pay attention or if I should bring it up...

 

[JamesW]

Bring it up.

PB said all is good...

"Not a big deal, it is only pressured up to get our plumbing inspection, thank you. "

 

[JamesW]

The point of a pressure test is to see if the plumbing holds pressure.

The plumbing does not hold pressure.

Results test failed.

Rubbish! The plumbing isn't holding pressure. You have a leak. It needs to be fixed before any further work is done!

Alex, It'll be a big deal when you lose water.

Alex, It'll be a big deal when you lose water.

... and the leak is under your new decking.

You know...I see so many of these posts where a PB says, "It's all good!!" when in fact it isn't. I have decided that if I started a PB company and ran it the way it *should* be ran...I would be a very rich man.

And that's after he's owed nothing and long gone.

It's like if you had new tires put on and the pressure went from 35 psi to 10 psi by the next day and the tire place said "No Problem you just have to add air every day". Um...no, I don't think so.

55 is too much to start with. 35psi is what I do and i set it first thing in the morning when its cooler out. If it drops below 30 we have an issue it can climb to 40s easily with sun. 2moro it should be higher than the lowest reading you have seen otherwise it's a fail. Often the plumbing is fine amd the leaks are from hose bib valves or the test rig. I dont do them amd if I did it would be cut in after a pressure test. Also never use old school turn handles, either quarter turn ball valve bib or nothing. Rubber seals stink

 

[alex800]

I have an update....

Perhaps I misunderstood my PB yesterday when they said " Not a big deal" because first thing this morning the plumbing crew were here and found and corrected the issue. One of the elbows was leaking.

30 minutes after they left the inspector came in and we now passed the plumbing inspection.

I appreciate all your replies. I was freaking about it.

I was freaking about it.

Don't blame you, I would be too. Certainly not something you want to find out about once it's covered up with concrete. Have a nice weekend. :Swim:
