    Grohe shower control; no flow

    Good eye! No I don't have a thread sealant. Do you mean something like Blue Loctite? Do i use it WITH teflon tape or INSTEAD of teflon tape? ...oh man, and here I thought I was done. Now I'll have to take it all apart again. Oh well, better now than later that's for sure!

    Grohe shower control; no flow

    So I solved it myself just as I figured in my previous post. The back story to this is: We had the main bathroom remodeled approx 3 years ago by hired contractor. Considering that was now done, I thought I'd tackle the ensuite myself. Two years ago in February I tore it down to the studs...

    Grohe shower control; no flow

    I think I discovered the problem! The pressure balance valve is working as it should! the hot water supply is shut off down in the floor by a hand valve but the cold supply needed to be left on to feed the toilet in the other bathroom. I would go and shut off the supply to the entire house to...

    Yes. I took the cold off for a moment to address tiny leak, but yes I tested with both supplies on.

    Grohe shower control; no flow

    Yes, I opened the two shutoffs; they require a 90 degree turn with a flat screwdriver. The control did indeed fill with water. I'm thinking it "wants" to route the water out the bottom. I moved the plug to the bottom. I'm wondering if the cartridge might be configurable for either top or bottom.

    Grohe shower control; no flow

    Here's looking at the control from the bottom and then the top.

    Grohe shower control; no flow

    I've installed a Grohe shower control model 19 933. I don't have any water coming out of the top. I understand the control is for either a downspout, or, shower control application. I am installing it in a walk in shower. The control came with a plug on top. I moved the plug to the...
