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.
