Moen 1222 cartridge - Water not coming out of spout but before the valve?

Question

Hi,
In my bathtub, I replaced moen valve 1222 thinking that this would be the problem of not having water coming out of the shower.
For my surprise, I still don't have water, however when the valve is removed, there is water coming out. A few drops occur with the valve installed.
please provide me your feedback if you know what is going on.
thansk,

Answer 1

remove the cartridge, turn 180 degrees, re-insert cartridge. It's installed upside down. To verify that the pipe rising to the shower head is not plugged, which would be unlikely in my opinion, take the cartridge out, put your hand over the cartridge hole and have someone turn the water on for you. This will force the water to go up the shower riser.

also, lubricate the cartridge with a small ammount of vaseline when you install it. This will keep the rubber washer from binding when you slide it in.

Answer 3

If you tried installing a new valve and you still don't have water coming out of the shower. You may want to check to make sure that the shower head isn't all clogged up or that the pipe going up to the shower head isn't clogged. If you installed a new valve and water will come out of the tub faucet, then that is probably the cause. It may be that it is limed up. If it is, let the showerhead pieces soak individually in a cup of Lime-Away or something like that.

If you still have problems, go to a bathroom or plumbing specialty store. Explain what's going on. Most likely they will be able to give you a good idea of the problem. Take pictures and the valve with you.
