My shower valve is approx 20 years old but it is not used more than 20 times per year. spare bathroom. valve controls the volume of water ok and will control the hot water normal. as soon as i turn to the cold side , the flow completely stops. not one drop of cold water. help
First, remove the shower head and test the valve. If you have plenty of
water at the shower with the head removed, then the problem is a clogged
shower head. Clean it or replace it.
What the hell...just replace it. You deserve it. Go buy one of those
cool shower massage heads to replace it.
If you discover you have poor flow at the head with the shower head
removed, then you have a blockage in your valve.
So you buy a 1/2 (female pipe thread) x Hose Thread adapter. Put that on
the arm for your shower head. Turn off the water to the house. Borrow a
neighbors hose and run it through a window and connect it to the shower
head (hose thread adapter). Now take the hose off your washer box and
drop the hose into the drain hole. Now turn on the water.
The water from your neighbor will allow you to backflush that valve. The
debris will backflush and wash out through your laundry hose on down
If that doesn't work, then yes, you probably need to replace the entire
(I'm assuming your already taken the cartridge apart and cleaned it)
Is your tub spout still running alot of water through it when you use
If so replace spout, if three valve, replace center diverter. If that is
Then yes take off shower head and see if you have the pressure, if so
shower head and or clean. If not head, then screw on .5 x hose adpt. to
arm, you will have to have one washer hose to connect to your outside
faucet then to
your garden hose which will connect to the shower arm. Leave faucet hot
and cold water off, turn on outside faucet all the way, this will let
the water go through the valve
and out the spout. If this does not work replace faucet. Read More At : & One Handle Tub & Shower Faucet...
