once again Google to the rescue-- GOOGLE " how to add sink shut off valve" how to videos.

This process is too in-depth for me to just sit and type here for you without knowing if you are using Copper, PVC, or Pex. Plumbing. However it is a fairly simple process for the average handyman such as myself who has done it many times in the past. But for a novice I am suggesting DIY How To Videos.

For Copper pipes:

shut off the main water supply to the water-line you will be working on

turn the water faucett on in the kitchen and bathroom and leave it there until you finish working.

If you are working on the cold water line then only open the cold water from the kitchen and bathroom. This is to allow air into the pipes so that the water will drain when you cut the pipe-- water in the pipe will not allow you to solder (sweat) the pipes together-- the pipes must be clear of water to reach its proper heat range for the solder to melt and seal on copper pipes.

if the tee on your valve is 2 inches from outter edge to outter edge then you will want to cut a section of pipe of about 1. 1/4 inches long.

once the pipe is cut use emery cloth, sandpaper, or a wire brush to clean the pipe ends in and out before applying flux -- once you applied the flux-- plact the valve in place in between both pipe pieces and begin to heat testing periodically with the tip of a solder until you see the solder starting to melt.

Why is the hot water pressure in your kitchen sink low but the cold water pressure is normal and as of last night both were equal and the hot water shut off valve under the sink does not shut off?

If the shut off valve turns but does not shut the water off, the washer in it has split and probably made it to the faucet. It was blocking part of the hole on the hot side and at some point either shifted or made it through the faucet and in in the screen in the end of the spout. Shut the main water off and replace the washer in the shut off valve.
