I have an outdoor water holding tank and draw in water using an indoor pump (set at 30-50 PSI) and an internal pressure tank (set at 28 PSI). I recently had to replace the internal tank because the bladder ruptured and filled with water, leaving the pressure tank un-pressurized.

While trying to follow the directions replacing the tank, I primed the pump and left a faucet on while plugging it in. The system itself pressurized fine throughout my house, but the faucet I had turned on is now leaking.

I noticed that when turning that faucet off it caused the flow of water to slow and then trickle and finally stop instead of immediately stopping. Being more focused on the entire system, I dismissed it. Hours later, I heard what sounded like dripping and tracked it to that faucet. I immediately shut off the water valves to that faucet.

To clarify, the cold water side has little pressure and does not immediately stop when the faucet is closed. The hot water side leaks badly as soon as I open the valve underneath.

I would like to know why that particular faucet started leaking. This is the second time over the years that I have replaced the pressure tank, but the first time I have encountered a problem.

More importantly, I would like to know how to fix it. Hopefully, it is a gasket/o-ring issue, but before I tear the faucet apart I wanted to see if this is something commonly known that I can check instead of going in blindly.

Maintaining a steady water pressure throughout your plumbing system is important. In fact, the pressure reducing valve may be the most important single factor in your entire plumbing system. Keep in mind that a nonfunctioning regulator might start leaking if you try to adjust it so have a qualified plumber to check it.

Once again, I have no idea what Spaparts is talking about...

Mtillisch, it sounds like some sediment/debris got in and gummed up the faucet washers or cartridge assembly. Just like you thought, you'll need to disassemble the faucet, clear the lines by running water through them and the faucet body and then inspect and clean/repair the parts or replace parts if needed...should get you up and running soon enough!!

Good luck!
