The chrome supply line to our toilet had the threads cut off. What's is the best way to attach a cut off.

Question

The pipe is 3/8" chrome

Answer 1

you can try a compression fitting,for the chrome supply line, but I would recommend the following.

or it may also be possible for you to take a pipe wrench and remove the old nipple out of the wall and buy a new one, teflon tape the threads and reinstall it into the wall.

Make sure to only install the teflon tape a full 3 turns only, as that is enough sealent for the threads, if you go more than 3-4 you may end up cracking the nipple.

Then buy a new angle stop and tape up the threads as needed (compression fittings do not need teflon tape or any sealent.

To do all this make sure that you turn off the water at the meter, or possibly in your garage you have a gate , or ball valve to shut off the water before it gets to the main line in the home.

ROSCoooooooooooooooooooooooooooooo

Answer 2

buy a new angle stop that will match the style and kind of pipe you have IE: cpvc, copper, pex, iron pipe

shut off the water supply to the house and replace it

once the 3/8 comp threads have been cut there's no other option

Answer 3

call a plumber

Answer 4

you can pick up pre made chrome 3/8 nipples at your local hardware store and new toilet stop with 3/8 threads.  spin counter clockwise out of the wall. put thread sealant on th enew nipple and thread into the pipe in the wall and do the same for the stop install a new flex supply and your set.

Answer 5

most 3/8 supply pipe have no threads.  it is a compression type fitting on one end and some sort of a "head" on the other.

are you sure the treads were indeed "cut off"??

i suggest going to your local home depot and purchasing braided 3/8" supply line for toilets.

Answer 6

Are you saying that the chrome plated supply line to the toilet in your home (you're just moving in?) had the threads cut off BETWEEN the water supply line into the bathroom and the toilet water tank?  Was the toilet REMOVED?  Is the supply of water to the whole house SHUT OFF?  If not, there HAS to be a cutoff valve in that supply line somewhere before it disappears into the wall or floor or wherever. As has been suggested already, I believe you should REMOVE the old chrome plated piping back to the connection at the block valve; purchase a new flexible hose connection with the proper fittings on each end to connect back up between the (should already be in place) cutoff valve and the (newly installed??) or old toilet.
