Replacing Supply Tubes

If you have a problem with water flowing to a particular faucet or fixture, you may need to replace the supply tubes.  Sometimes supply tubes can burst or become clogged with sediment.  If this happens you may need to call a professional plumber to come out and take a look.  Replacing supply tubes is generally fairly inexpensive and does not require a large amount of time.  If you feel that you are somewhat handy, you may want to take a shot at it yourself.  I would always warn someone, when working with water lines, to be careful.  Starting jobs that you cannot fix may end up costing you more in the long run.  That is why if you do not feel comfortable doing this yourself you should call Glover Plumbing.

To replace a supply tube you need to shut the water of at the stop valve located at the base of the supply tube.  Newer valves are a quarter turn for complete shut-off but older valves can take a few full turns clock-wise.  After the water is off, unscrew the supply tube (this can depend on which materials were used for the supply tube) from the stop valve first, and then unscrew it from the fixture. (Sink, Toilet, Tub, etc.)

To replace the supply tube, simply purchase a braided stainless steel supply tube from a hardware store.  A braided steel tube is most likely not the kind of supply tube that you just removed, however, they are much easier to install for the beginner plumber.  The reason they are easier to install is that you don’t need to cut them to size to fit between the stop valve and the fixture.  Too many times you can cut the plastic or copper supply tube too short, and up with a trip back to the hardware store.  The braided option is also easier in tighter spaces like under cabinets and under toilets.

Make sure when buying the braided tube that one end matches the stop valve.  This is usually going to be a 3/8 or ½ inch opening.  Install the tube from the stop valve first to the fixture second.  Use Teflon tape to get a good seal.  Turn the valve back on, once you are finished, and check for leaks.  You should be good to go.  If you notice any problems, be sure to call a professional plumber.   Hope you found this useful, thank you for reading.  Good luck from Glover Plumbing.
