I have lived in my newly constructed house 3 1/2 yrs now and have been having a problem for at least a couple weeks now or that I've really noticed. My bath faucet is leaking alot. I Googled and you tubed how to fix it. I have a moen fixture and got a replacement cartridge because it seemed to be a common problem, but after disassembling the fixture, removing the old cartridge, turning off the water to the house, leaving the bath tub and another faucet open to relieve pressure and waiting a while it still continues leaking rapidly and even more so. Another thing which I don't know if pertains to this issue is that in the first year after moving in, my bathroom sink was leaking quite a bit too, and just last year the same bathroom toilet was running water all the time. I don't know what to do or if their is a deeper problem but it seems really weird all this is happening after only 3 1/2 yrs... Could you give me some advice? Thanks

The main valve might be defective and not shutting off 100%. Do you have a hose bib or faucet at a lower elevation than the tub that you can open?

They are all individual problems and not related to each other.

As hj says these problems are not related. tackle one at a time. Start with the bath tub valve by removing the stem and cleaning the inside of the valve with a wire brush. If you have the older moen valve the brush will be a 3/4" copper cleaning brush. If you have the newer Moen Shower valve you must us a different brush. If you can leave the water turned off for 6 hours, I would stuff a paper towel that does not come apart when it is wet, inside the valve and fill the inside of the valve with vinegar. Just cup your hand next to the valve and fill it so that your hand keeps the vinegar in the valve until the paper towel is soaked. Keep the paper towel inside the valve by tapeing it in with wide masking tape. Let is set for 6 hours then rinse it out and replace the cartridge. By not doing this cleaning, you may have ruined the O-Rings that seal the cartridge, so you must replace them. Then continue repairing the other leaks i.e. you toilet or lavatories.Good luck

I'm not finding any that are lower but I left the main water valve off all night and it seems as if it has stopped leaking.

Thank you so much! I appreciate your input and will follow your advice PlumberLoren

If I did that when I replace a Moen stem, I would NEVER get done.

Getting in a hurry can cause call backs...just a thought. It also just occurred to me that your water may not be as hard as the posters. Believe me with all of your experience, I am not questioning your procedures.
