The water in my tub/shower stopped working. I did my research on the net to discover the cause and I also went to Home Depot explained the problem. The worker at home depot helped me get the right part I needed to replace the valve stem. I came home, took the faucet handle off and can see what I need to do next. Everything seems perfect and ready to go, except I can't remove the old valve stem. It seems like the old one should just slide out and the new one replaces it. How do I get the old one out without damaging any of the pipes or hurting myself.
Check back on your website to see if they have the procedure for removing/installing the new stem. These usually have to be turned to allow them to be removed. You should be able to purchase a tool to help you release it. Also, be aware the old stem could be hard to remove due to build-up and/or torn seals. After you get it our, try to remve and deposits in the valve and then apply a little lubricant to the new stem before you insert it. Be sure the lubricant is compatable with the seals.
Do you have a valve for the hot and one for the cold, or does one valve control both? If there are two valves they should just unscrew. You might need to go back to Home Depot and get a wrench designed for valve stem removal. (Before you go, spray it with penetrating oil such as WD-40 and let it do it's thing while you're gone. If it's just one valve for both, there's probably a collar that screws on and holds the cartridge in place. After that is off, the cartridge should slide out-ususally with a little 'persuasion' from some pliers. (But don't try to twist it) Hope you get it.
