The Delta Single Handle Tub
And/or Shower faucet, How to repair it, How to replace
it and what NOT
to do!!!
|
 |
Above is the Delta 622 single handle
tub and or shower faucet. This faucet does not have any
type of scald guard protection or balance control
protection, It would not be legal to install this faucet
in a new home with the current safety codes.
This is a simple faucet to repair as long as the nut is
not stuck. |
 |
This is all you need to repair
the Delta 622 Tub and Shower
Faucet. I recommend replacing
the ball seen on the left side
of the image, remember you can
click on any image to see a
larger image. The red tin is
plumbers grease, do not use any
other type of grease on any
plumbing fixture. next to the
grease is a repair kit for the
faucet.

Some kits come with a new ball
and some don't. this is what is
inside the kit |
 |
First things first, TURN OFF THE MAIN
WATER VALVE. then if possible open a faucet at a lower
elevation to keep water that may get past the valve from
leaking out of this faucet when you are repairing it.
Then remove the button.

As you can see there is a screw behind the button this screw holds the handle on. |
 |
Use a Philips screwdriver to remove the screw, the handle should just pull off. |
 |
This is what it looks like with the
handle removed, note that it is not necessary to remove
the chrome back plate to repair this faucet. This is a
very important part of the repair, test to see how tight
the nut is on the faucet. the nut needs to turn counter
clockwise, STOP !!! Use minimum pressure to loosen this
nut, if it does not feel like it will move with minimum
pressure, STOP. Read the following so it will not happen
to you.;

I tested the nut on this faucet and it
will not move, I removed the chrome plate so I can show
you what will happen if you just get a bigger wrench and
put hard pressure on this nut. Please notice the
vertical position of the stem slot it is straight up and
down. |
 |
In this image I am applying more then
minimum pressure, notice the position of the stem slot.
If you are trying to remove the nut and you see the stem
slot moving. STOP !! There is no turning back at this
point.

In this image I am continuing to turn the what you may think is the nut, but is actually the whole body of the faucet. |
 |
You may be thinking how can the whole body turn, the
pipes in the wall should prevent the body from turning
|
 |
The problem is with the poor design of this old faucet, This is not to say that Delta makes a poor faucet, Delta makes great faucets, and has long
since corrected this problem in newer faucets like the one I replaced this one with.

There is a main brass body that connects to the
pipes in the wall, but there are 3 little soft copper
tubes that connect from the main body to the part of the
body with the ball inside of it. |
 |
This is what will happen if you use too much
pressure on the nut, Trust me it does not take allot of
pressure to break this part off, and there is no way to
repair it, you will have to replace the whole shower
valve. |
 |
This is the back of the part that still has the nut
attached to it, note the 2 little copper tubes, the
third one is still in the main body. remember you can
click on any image to see a larger image.

This is what is left in the wall, notice the third little copper tube, It's no wonder this part will twist off.
Now that I have destroyed this faucet I have to replace it, This shower happens to be a one piece fiberglass unit and there is no access from
behind the shower valve to replace it.
