Moen 3033 No Water

Moen 3330 No Water

Hey guys,

I feel like my issue should be real easy.

I have a shower that has a newly installed Moen 3330 valve. After I installed it a few months ago I tested it and water came out of both shower heads. I recently tiled the shower and put the escuchean on last night. Nothing came out. I took the escuchion off and thought that I must have closed the little stop valves. Turned the valves one way and tested withough handles. Simply by pulling the lower handle stem out. Nothing. Turned the screws the other way and again nothing. Pulled the lower stem out and turned the top diverter handled a complete 360 degrees. Once again nothing.

There is definetly water coming to the room because I have a jacuzzi tub in the room and it has water. The piping for the shower branches off the same 3/4" line that runs to the jacuzzi. Also there are no other valves in the walls.

I stuck my hand into the hole with the valve and felt the lines in the walls. They weren't cold as if frozen. Also the valve is in an interior wall not an exterior wall. The lines for the jacuzzi run on an exterior wall so those would be most likely to freeze.

I feel like the answer to this one is going to be real simple. Any ideas?

Assuming the mixer valve is a positemp,. you must have BOTH hot and cold water going to it. If one is off, it will not pass any water at all.

I will double check that tonight but I'm almost 100% sure that water is circulating to the valve both hot and cold.

Two questions:

1) Is there anyway that it's possible that the line to the shower could be frozen if A) The jacuzzi that is 8' away has hot and cold water and they both branch off the same 3/4" line and B) I stick my hand in the wall cavity and the pipes don't feel cold at all (interior wall not exterior)

and

2) The stop valve screws that are on the valve. Do they need to be screwed in or screwed out to allow water to pass? The directions do not specify.

Thanks

I pulled the valve apart last night and ran the water. The water comes out fine. I only pulled the lower part of the valve apart. Reason being is that when assembled I didn't feel any resistance when pulling out the stem.

I believe the water isn't getting past the stem.

Does anyone have any ideas for me?

Thanks

I transposed the numbers on the valve. It's a moen 3330.

Daggummit,

Got it. This is Somewhat redundent. With the 3330 you have to pull both stems out in order to get the valve to work. Seems unnecessary.

I'm going to test this out when I get home.
