Leaky faucet due to a 'broken' valve?

Question

I have a leaky compression faucet and I'm having difficulties pinpointing the source of the problem.

At first, my instincts told me that the problem was at the stem assembly, but upon further observations, I realized that when I closed the shutoff valve under the sink the drips were still continuous. Not to isolate that problem alone, I also continued my investigation by diagnosing the stem assembly. Thereafter dissembling the handle, I noticed some calcium deposited embedded in the retaining nut but no corrosions (unfortunately my inspection stopped short at the retaining nut because the calcium buildup around it made it impossible for it to budge).

I want to invest my repairs in the valve seat because that's where I believe the problem lies but what do you guys think? And if you have any suggestions on how to fix the valve, I would be delighted to hear it.

Here are tips on fixing a leaky faucet

Answer 2

well you always should change the valve seat. you will need a seat tool and new seats. try this. it also sounds like you need some new angle stops.

Answer 3

It sounds like the seat on the disc for your angle stop is leaking. Do youself a favor. Take the angle stop out completely and install a 1/4 turn valve in its place. It's like an angle stop, but uses a ball valve assembly instead of the disc. You shouldn't have any problem with leaks after that.

Answer 4

I would say the valve seat. Replaced mine and everything was fine. Why when you close the shut off valve did the drip not stop???? Calcium may have corroded the shut off valve and it may not be working. I think I would look into that.
