Hi, My valve leaks at the bonnet, The valve is original (40 years old). There is solder where the threaded area meets the pipe, How can I tell if the valve is threaded onto a soldered adapter or if the valve is all one piece sweated onto the pipe. I would love to be able to just unthread it and thread another one on.

Unfortunately you are SOL. Those valves are soldered on to the copper pipes and have to be unsoldered to remove. They are not threaded on.

Thank you....S I should put a torch on the valve side to break the seal and pull it off? Do you think a compression type valve would be ok after cleaning up the copper? Are these standard 1/2 inch . Can the valve be repaired

anyway...thank you for your reply

Yes, can remove with torch. Disconnect hoses, open valves to drain water out etc.

It is 1/2" ID copper tubing. Standard compression will fit after copper is cleaned up and there is enough of it sticking out.

Or could just solder on 1/2" copper male adapter and thread on new washing machine valves.

Nibco is still in business, but I would bet that replacement parts are no longer available.

Thank you....I would love to just cut the valve off but I do not want to come up short for a compression type replacement, so I will probably heat it up and pull it off. I don't like using a flame that close to the wall. I'll figure out some type of home shield.

P.S. I live in a 6 unit condo. We each have a main shut off. We also have a main building shutoff in the end unit. Of course now that I tested my main it's leaking and all it is , is a wheel sticking out of the wall. Now I have to cut the sheetrock and see how that looks like, get a replacement, arrange to shut the building down and replace it

The Nibco valve can be repacked with the water ON.

Assuming that it shuts off 100% all you need do is unscrew the packing nut (NOT, repeat NOT, the bonnet) and repack the valve stem.

bern... i'm thinking there is no packing nut to unscrew.

looks to me like there is an "O" ring seal of some kind in there.

hotice how all these valves have smaller packing nuts with threads showing below.

at least it is not an OSY valve.

since my main crap out too I went to my plumber who used a pro press and swapped out the three valves. THANK YOU all for the responses

packy,

i stand corrected


OP,

way to go ! you hired a plumber to do plumbing !

i would hope the 'plumber' attached a couple of propress female adapters and screwed in new valves.

always pretend it is going to be you who will have to deal with a future problem.
