I have a 1988 house and these compression stops have never been changed. I shut off the water on one to repair a faucet and it failed at night resulting in a mini flooding. Brands is Jameco.

I disassembled it and went to Ace hardware but the rubber flat washer they gave me seems to thick and obstructs the flow.

Since they are all old, I feel it is safer to just change it and all of the others. There is also a lot of calcium deposits since water in Miami is quite hard.

The shutoff valves are all soldered to the copper pipe. Is it common? Should I go with a better design that could be disassembled easily?

I believe the size is 1/2" x 3/8" and brands are jameco and brasscraft. Should I go with a better design? Any brands you guys prefer?


Thanks a million.

imo:

depending on the length of the 'stub outs' from the wall either:

(if long) cut off and install compression stops

OR

(if short) unsolder and solder on threaded adapters for threaded stops

OR

buy new Jamesco stops and 'cannibalize' the entire 'guts' (if they fit)

The copper tube is quite short so I will have to heat the fitting with a flame to remove it.
What about brands? I also looked at sharkbite but it seems that they can fail? I saw a thread Re: this on this board.

after you heat and remove the old stop you can either:

solder on a new 1/4 turn stop

OR

while solder is still 'hot and wet' wipe as much off as possible
then clean the Cu stub of all old solder (emory paper and/or steel wool)
and use a 1/4 turn compression stop

OR

for peace of mind - call a plumber

I would not use a sharkbite on a short stub. I never install one unless there is enough room to insert the removal tool behind the valve and trim ring. If there's a leak, you need to be able to pull it back off. If the pipe is not secure inside the wall, you may not be able to push it on fully. Sharkbites need a smooth, round pipe OD to bite into free of all solder dimples, dents, and ridges. If installing a sharkbite always use a little plumbers grease to help it seat and seal.
