|Ok so you
were able to get the nut off of the Delta 622 or other older Delta single handle
tub and shower faucet. If not,
Please go back here With the nut off , the ball and
other parts just pull out then you can just set them on the side, many times a
ball can be cleaned up and re used, but if the ball needs to be replaced, please

single handle tub and shower valve.
Notice the 3 round holes, the top left hole is
the hot water inlet, the top right hole is the
cold water inlet, the hole on the bottom is the
outlet, this allows the water to go to the tub
spout or the shower head. There is nothing in
the bottom hole.
hot and cold water inlets, inside the Delta
shower body, each have a spring and a rubber
seat in them. Remove both of them from the
faucet and throw them away.
is what the spring and rubber seat look like,
notice the mineral deposits on the rubber seat.
The springs get weak and the rubber gets worn,

not hurt to apply a little grease to it also.
this point you have installed the hot and cold
water springs and seats in to the hot and cold
water inlets, inside the Delta shower valve
body. Now you are going to insert the Delta ball
with the boot and plastic retainer.
note the notch on the right side of the Delta

into the notch.
