I need to adjust the water pressure in my bathroom sink. The pressure is fine through out the rest of the house, but in that sink there simply isn’t any. What on earth can I do?
If the pressure is bad for both hot and cold, and the volume does not increase when both are opened, then the obstruction is probably in the aerator at the end of the spout. Otherwise, you have to find the obstruction in the lines to the faucet or to the spout.
another cause could be if you have the old style tap washers they pull apart leaving the washer on the seat when the stem lifts. Restricting the flow. But check the airator first
