Can't unscrew shower faucet
I have been trying to unscrew the nut that holds the spindle together with the valve seat of my shower.

I successfully removed the handle, took out the decorative casing. But the nut that the spindle goes thru into the valve seat is not rotating even after a thousand sprays of WD40 (this is an old old house). I have used all my power with the wrench but I can't even budge the screw.

Is there any way to get the spindle out? I plan to change the entire stem and spindle with a new one, if I can get this out.

Name of faucet would help if not then a picture.

This is an old faucet, I don't know the name or make. Its a compression faucet, with a spindle that contains the O Ring at the end that goes into the wall to the valve seat.

Attached are two pics, that I just took.

Will that nut holding the spindle in unscrew from there, looks like an old crane valve to me

Not sure what a crane valve is. But the nut simply does not budge from its place, no matter how much power i use with the wrench. Any way I can get the entire spindle out, if I can't unscrew the nut? Could there be another lubricant to losen the nut rather than WD40? Should I cut the screw with a saw? My fear is that doing so would permanently leave the spindle inside the valve. What do you think?

That has to unscrew or it don't come out, last option is open wall replace entire valve.

Would cutting the screw with a saw work?

Ron The Plumber 12-29-2007 09:29 AM

No. Sorry

Just another 2 cents here. Instead of using brute strength which can actually work against you with brass, try a light but rhythmic tapping on the wrench so as to set up a vibration. Also, try plain old Liquid Wrench penetrating oil both on the shaft and the fitting. WD40 gets way too much play and it's not always the best chemical for the job. Keep your taps rhythmic and light. Don't bang on the wrench or valve! It just may do the trick. Good luck.

heat it up!
Take a hair dryer and heat the nut up. After it is good and hot then try it again. Maybe it has left hand threads. Try turning it the other way

Another good penetrating oil is PB Blaster, WD is not up to the job. Heat is GOOD, the expansion and contraction can help break that joint. Any vibration will help get the penetrating oil into the threads. And turning counter clockwise A LITTLE, can help break frozen threads (even on RH threads)

if you open up around it just a bit you will see a larger hex surface. that in the pic is the packing gland its stuck becuse it is smashed from pliers. they crush easly.
open the wall and get a set of tub scokets to remove the stem. then replace it. type it is ?? old from the escution in the pic. mabe price phfister or sayco,but there are 20more it could be. take the stem to a good plumbing shop and see it it can be goten. you can also loot on line for it then try to order it.
if there is acess?? you acn get that type of faucet fo about 100$ in washerless

here is a start
