Thermostatic Valve Shuts Down on Full Volume

Our shower's Altman's thermostatic valve's performance has changed.  Originally, you could turn it fully on.  Now, after the water gets to the temperature it's set for, it shudders and the water stops flowing.  It will start again, but not in the fully on position.  Solution...besides don't turn it on fully?

I would check the strainers/filters becuase clogged strainers can lead to decrreased water pressure and therefore improer mixing... there may be strainers at the supply valves, at the intake to the faucet and the cartridge...

I have a Jalco 3/4" thermostatic mixing valve that I just installed to relace one that leaked. The water comes out fine but I can't get it to mix when I turn the knob -- it either comes out all cold or all hot. Solution?

    I called the shop that I bought the mixing valve from (The Chicago Faucet Shoppe) and they told me the same thing. I removed the mixing valve, cleaned it and reinstalled it. It still didn't work. I went back to The Faucet Shoppe and exchanged the mixing valve (even though the very knowledgeable salesperson said that the problem wasn't the valve) and installed it. It still doesn't work. Is it possible that it is incompatable with my shower tower or is there somethign else I should try?

Shower valve clogged

Moen products are the worst on the market. Remove the trim. Check that both stop valves are fully open. Then get both cartridges and replace them. Moen will warranty them, but you have to wait for delivery.

Shower wont fully shut off ,how do you replace or clean out valve ,its a exposed single lever thermostatic mixer valve,6 months old

you have to first turn off the water to the whole house and open a faucet upstairs and downstairs to properly drain down your pipes (less messy).

Take the handle off with an allen key (hex). Undo the 2 screws that hold the faceplate on and it will slide off with the sleave. You will find a brass valve body with a lock ring which screws off by hand. It may be tight for half a turn and should then spin off. If it remains tight you still have pressure behind it and are about to get wet (go make sure the water is off and drained). The cartrgidge should just slide out, if tight give it a turn and it will pop out. Take it to any hardware store and get a new one (many stores give replacements for free if you give them the cartridge). The cartridge will be set to a low temp for safety and you may want it to be hotter. The adjustment is on the front of the valve. Look for the little notches on top of the cartridge to adjust.

Also note that one side of the cartridge says "hot side" on it. Take a look in the valve body for debrise that may cause the same problem. Now just replace all the parts and enjoy.

I changed the stem on hot water because shower leaking- now no hot water from shower head when water turned back on- wont pass stem and some spreay from where stem is?

I am not sure what brand of shower valve you have but it sounds like you lost a peice of rubber or plastic in the valve and it has either lodged in the diverter or somwhere from the valve to the shower head. Is it posible that you got the wrong stem or switched stems or maybe it was put in backwards. Wish i could narrow it down for you,Need better info.

There is virtually no water flow from the shower faucet we have just plumbed in. there is plenty of water pressure to the sink which is on the same lines. is there anyway to take off the thermostatic...

shower heads are fitted with a 'flow limiter' which is no more than a washer under the sealing gasket where the 'head' fits to the supply pipe.un-screw shower head from pipe,remove 'limiter' reinstall & enjoy.

Apparently valve not working, how can I check it?

sounds as though the thermostatic radiator valve is stuck although the valve settings can be set to max. sometimes hitting the side of the valve will free the stuck spindle & get it working again.

If not a drain down of the system & a new valve fitted

Not able to pull up the shower valve

The valve is in upside down. Sounds like the shower head runs all the time and thats what fills the tub? The valve needs to be flipped OR the diverter in the valve needs to be switched to the other side of the valve. If this is a one handled valve it is installed upside down. UP is indicated on the valve.

The valve can be reused just turned over.

Water kitchen sink

I would check the strainers on the intake and the faucet spout. It is possible that sediment has built up and now is impacting thermostatic flow from the faucet... if one side is clogged its hard for the faucet to balance... try the stainer on the spout and any other strainers that may be on the supply hoses, valves, intake, etc...

Hansgrohe concealed thermostatic mixer ref no 1537418

check for sediment in your valve body... sometimes sediment can build up particularly in hot water pipes and that can cause the pressure balancing function of the valve to limit total hot water and therefore you cant get it hot enough... here is a link to what I think is the proper valve and the instructions for installing it... you'll want to follow the instructions for flushing and pressure testing... if you have good pressure at the thermo body then you might try adjusting the hot limit stop also covered in the document linked below...

Hope theat helps...
