Delta 622 What not to do page number two. Back to page one
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.
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.
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
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.
