Leak At Pressure Tank Pipe Connector?


We had a guy come by a while back to look at a pressure issue we were having (turns out the water filter was super dirty and collapsing; we didn't think it needed to be changed after only a few months and didn't know to look since we just moved it), and I asked the guy if he could see if there was a leak from our pressure tank. It's perpetually wet around there and the cement is black.

He told me that if the tank was leaking, that there would be no pressure since it's a bladder inside. He said that it's condensation causing this. So I put a dehumidifier right there under the stairs with the water equipment, and it's still soaking wet down there.

I finally stuck my camera under there and took some pictures. When I touch the part where the big copper pipe and the pressure tank meet, it's quite wet. I think there's a slow seeping there.


Has anyone had any experience with something like this? What was the issue? It just seems awfully excessive for condensation.

Here are the pictures (sorry; one isn't upside down, but it uploaded upside down):

Looks exactly like a small leak. No reason that a small and finite leak wouldn't weep like that and not empty the tank.

Is it a relatively easy fix? I don't know what this connecting spot is called, so I can't fins any tutorials online showing how to fix it. I searched for a bit, but gave up.

Unscrew the pipe. Apply some sealant, tape or pipe dope or both, and re-install pipe.

That's what I don't understand. How do you unscrew it while it is connected at the other end (where the T thing is)?

And I would have to figure out how to drain the tank first, no?

Hose bib is right on the bottom. Turn the well pump off (breaker), close the out bound line, drain the tank, fix the leak.

You might need to saw the pipe in half and unscrew both halves. Then use a union and two new pieces to replace the cut pipe. A union allows two pipes to be joined without having to screw either one of them into the fitting.

Re: Leak At Pressure Tank Pipe Connector?


The pump is cycling on again soon enough that the pressure tank does not empty out due to that small leak.

Now, a leak high up on the pressure tank that lets out air will lose the air cushion and necessitate frequent recharging to restore normal system operation.

Of course you need to turn off the pump and open an upstairs faucet or laundry sink faucet to depressurize the system before working on the problem which will in turn almost empty out the pressure tank. Ideally you will need an additional drain valve down at that level otherwise you will still get some water all over the place when you cut the pipe. So you might as well add a spigot down there (if not already) to depressurize the system with for next time.

From what I can see of the pictures there are only 2, possibly 3 threads showing on the copper pipe. Us old folks that's done a lot of screwing would say - " some idiot buried it " - so, my advise is, when you remove the copper pipe from the plastic, look real close for a crack in the plastic. I won't bet all my Social Security check on it but I'll see your 5 and raise 10.
