I have close to 20 stuck toilet/vanity valves in my house that are stuck. I can’t close them for repairs. They are full rotation gate valves.

Looking for the best solution.

1. Remove and replace the internal valve components
2. Cutoff and replace with new quarter turn ball valves. (Is this even an option if there isn’t a lot of pipe coming through the wall?)
3. Purchase piggyback valves?


I also have gate valves on my heater heater that are fused in the open position. Would you replace valve intervals or cut off and go ball valve?

Thanks

 

Cut off and replace. For most sinks and toilets I'll use quarter turn valves. If its 1/2" copper I like plain old compression valves.

 

If you have 1/2" copper pipe exiting the wall, my preference is to cut off the old valve and sweat on a 1/2" copper male threaded adapter and then install threaded 1/4 turn ball type stops using teflon tape to seal the threads. I like looking to the future and making future replacements as easy as possible. I have gotten lucky a couple of times and have been able to just replace the guts on a sweated stop.

 

Both Joe and XSPLR are correct, but use Sharkbite valves. No need to sweat or thread.

 

Hi, We don't know how your valves are attached to the pipe. If they are 1/2 inch compression valves the job became very easy. I have found the valves have two types of threads . I would buy one of each. Loews has one and Home Depot the other. At home shut the water off and drain the line and remove the valve leave the ferrell and nut on the pipe.Try to fit the new nuts from the valves onto the old valve. the one that fits smoothly is the valve you want to use. Most houses have the same brand of valves so you can buy what you need, but keep the other one until your all done, you never know. I done this many times it works for me.
Good Luck Woodbutcher

 

My valves are soldered on. I think I’m going with a soldered connection and possible threaded adapter. Not a fan of sharkbite..........I can’t believe they will offer a consistent seal for a lifetime.

 

Here is a photo of the valves. Out of curiosity, can this be rebuilt with a quarter turn ball valve, rebuilt with a similar gate valve or is replacement the only option?

Thank you

 

You don't rebuild a part that costs $8. There is no kit to do that. Like I said earlier. Cut it off and use a compression shutoff. You can also use sharkbite fittings. Your current shutoff didn't last a lifetime either, did it?

 

Regarding Sharkbites, nothing in plumbing is for a lifetime. I was doubtful about SB's in the beginning so used in my own house before other people's. The oldest in my house are 14 yrs with no problems yet. My only complaint on Sharkbites is the cost.

 

I have full trust in shark bites for exposed piping, But not in an enclosed or behind wallboard.
