 Need advice to service a Symmons shower Valve
Author: jonath24 (CT)

I need to service a Symmons shower valve because it is leaking. It is 40 years old. It is quite amazing that it has been working for 40 years without any problem until now.

As always, the most difficult part of the job is to open the valve. I have 2 issues.

(1) The handle is stuck. The handle is made of metal. It is stuck to the spindle. I have tried a Faucet Handle and Sleeve Puller. It does not work because it is so stuck.

(2) Then I thought I wanted to remove the cap without removing the handle first. I cut the dome cover to expose the cap and was able to slide a wrench to engage the cap. Unfortunately, the cap is also stuck. I did not want to apply too large a force because I worried that I may damage the pipework behind.

What would be my options here?

In Youtube, I saw people twisting the handle to break the attached spindle. I suppose I can do that, but I am so worried of being not able to open the cap.

What is the best way to open the cap? Should I apply penetrating oil? Should I try an impact driver? I have both, but I am so worried.

In the worst case, I suppose I have to open up the wall if I have to replace the whole valve. Is there any alternative of servicing or replacing?

Thanks in advance.

You could try pulling the handle with the puller after using a propane torch to heat up the handle splines whre it engages the shaft. Repeated heating and application of penetrating oil (I use Liquid Wrench) will help.

After the handle is off, a strong impact wrench shoud get the nut off.
