I have a Well-Troll system, I just replaced the 75psi relief valve on the output of my tank. And it still leaks it seams that when I use water the pump (submersible) kicks on and pops the relief (spilling 3 or 4 gallons) nothing was changed or tampered with except the changing of the relief valve. Any ideas would be great... Thanks John:confused:

John,
By "still leaks", it implies that both the old and new PRV were both leaking. If that is the case, look for a flow restriction between well and the tank. It could be a valve partially closed, or a defective valve that is stuck partly closed, or a debris blockage in the line. If you have chlorine injection, it could have completely clogged the pipe.

If you can't determine a blockage, you could adapt a pressure gauge to put it where the PRV is now. Then, you could watch and see if it is a defective PRV, or if the psi really is jumping up high enough to blow.

Does the valve blow the entire time the pump is on, or only at first?

Let us know, so that we can help you solve it.

Hey John,
What's your bladder tank set at? Cheers, tom

Oops, I missed it in my earlier post. You said the PRV is on the output of your tank. Now, we really need more info. If you could post pictures of your setup. Or, describe the flow pattern of your setup. Do you have only one pipe on your tank? Usually Well-x-trol means you have a bladder tank.

After the tank was drained I checked the bladder psi it was less then 10psi so I increased it to 28psi ( I have a 30/50psi switch) changed the PRV and turned the power on. Now sometimes after the pump runs and psi goes up PRV leaks. I checked the bladder psi after the pump stopped and it was @ 78psi but why I guess is the question

John,
It's good that the PRV is doing its job.

Check the pipe under your pressure switch. It may be clogged allowing the switch to over-pressure. Or, you may have a bad diaphragm in the switch, which would require switch replacement.

In the picture is the well on the left or right?

The line on the left comes from the pump. If the line is cloged what is the best way to clean or flush the line/system. Thanks for all your help... John:rolleyes:

John,
Check the 1/4" pipe under the pressure switch. Run a piece of wire or something through it and make sure it is clear all the way down into the brass 1" tee.

While you have the switch off, look inside to see if you have some crud inside the switch. You could replace the switch while you have it off. I personally would, but I don't like doing things more than once. If both the switch and the pipe are clear of blockages, you definitely want to replace the pressure switch, since that is probably your problem at that point.

Thanks Al, I replaced the press sw, gauge(both clogged I just replaced) , prv, blew out the lines reset the bladder press to 28psi. Its like new thanks for all your help... John :)

You are welcome John. Glad we were able to figure it out.
