I have a single handle kohler bath tub faucet I am not getting any cold water out. i have taken this apart and found nothing that i can see that would impede the flow of water ?is the mixer valve at the root of this problem Thank you

Sounds like the cause of your problem is the pressure balancing spool. Call Moen at
1-800-289-6636 and explain the problem. They will send a repair part to you free of charge. the link below is a "blow up" of your valve.

Take handle back off and see if it has a dial that can be removed and repostioned. take off and move it about 1/4 turn counter clockwise and reinstalled and try to see if mixture is correct.

Can you remove handle , behind handle there should be a dial to move to increase hot or cold supply.

Remember where you start and remove it and replace a 1/8 to 1/4 turn counter clockwise, just put handle on try it and see if it changes and adjust accordingly.

is this a standard bath tub?? if so the answer is no only pressure from hot/cold usually thru the access panel other wise you will have to crank up the water heater unless you have an on-demand water heater located near your access panel. which raises a second question. your faucet? is it a single handle for both hot/cold or two individual handles? if its a single handle try opening up your hot water valve in the access panel to allow for more hot water flow and slightly decresing your cold water valve hope this helps good luck!!!!

Try draining the system and apply air pressure (min 30psi) to each faucet. Open other hot water faucets to allow pressure to vent. Next try draining and cleaning the hot water tank.

moen does not have a ball and washers....sounds like a Delta maybe. Moen uses cartridges. Either way sounds like a balancing spool problem....but you will need to make sure of the right name for the faucet to get the parts.

You will find a quicker answer and free parts for your bath room faucet at link above . I am sure it is the mixer valve assembly. If you are not a plumber I suggest a pro be called.

The device which directs the water up or down is called the diverter. Your diverter is not fully up or fully down. Rather forcefully push and pull the diverter a few times and your problem may be solved. good luck.

This is a pressure balancing valve that needs both cold and hot water pressure to operated. It is an anti-scald safety operation.

Good Luck, Phil

If you put on the cold and Nothing at all comes out, check the water supply valve to the tub. If it comes out alittle ...the washer probiblly came off and is stuck you will have to remove the valve ,but 1st check that the handle is not stripped ,and that is actually moving the valve to the open position Turn the handle and see if the handle backs out ,like its trying to open.
Please rember to leave me some positive feedback if Ive been Helpful! Thanks !
