How do I free up a tub/shower faucet?

Question

The tub/shower hasn't been used for a few years in this home I inherited. The well water is hard and I think that's the problem. The faucet is one of those single handle type you pull/push to turn on/off. Won't budge. Tried penetrating oil and CLR, still no luck...

Answer 1

Try some vinegar.

Answer 2

If you can, valve off that particular section of plumbing. If not, valve off the main. Remove the existing handle, soak it in CLR. If that doesn't work, you should make sure you are getting water to that faucet. You can do that by slightly opening the valve you closed earlier and checking if the water is flowing thru the faucet visually(now, don't be stupid and open it to far, you will only flood your walls). If you have water at that site, then it is a simple matter to purchase a similar type fitting and replace it.

Answer 3

You might get it freed up, but chances are you need to replace the whole thing. It sounds like the o-ring seals have bound to the ball valve assembly in the unit. If you get it to move at all, it will probably leak by the o-rings, and have to be replaced anyway. Hard water, mineral deposits, and lack of use has probably rendered this unit useless. See if you can cut an access hole in the opposite wall (if it is an interior wall), and replace the whole faucet assembly. You may have to go in from the shower side if it is on an exterior wall. Good luck.

Answer 4

First close the main valve.
Then dismantle the faucet completely, clean it from the stone sediment, put some soap on the moving parts, check it, and mount it back.
If you'll use it, it will last an other 50 years with no other maintenance.

Answer 5

Best to just replace it. Either DIY or hire a plumber.

Answer 6

Change the cartridge.
