I have a Kohler single handle wall mount faucet in the MB. Water flow barely a trickle.I have removed and replaced the cartridge with no change in the water flow. Both cold and hot side are equally affected. No aerator in use. Anyone got the fix? [email protected].

Is it shower or sink wall mount faucet ?

It is a bathroom sink faucet. Kohler "Falling Waters" model. Two parts from the wall... one is the valve body with cartridge, which is connected in the wall to the spout. As the cartridge is OK and the minuscule flow from the spout is equal hot or cold, I'm thinking that there is a blockage in the spout or downstream from the cartridge. I have not inserted a probe of any kind in the spout. Was considering applying some air pressure to "back flush" the system.

Most likely it is either the cartridge or spout. If spout has a aerator, remove it and run water w/o aerator attached to see what flow you get.

As far as spout goes - the spout is easily removable. You can take it off too to see if you are getting volume through the faucet.

Double check your cartridge installation. Visually inspect the interior of the body to see if there is any obstruction lodged inside h/c water inlets.

No aerator. Guess I'll have to disassemble again next weekend and do a through check for debris. I'll let you know how it comes out.

Thanks

Looks like I did something right. Disassembled, removed the cartridge, flushed out the supply pipes to ensure no blockage, flushed the spount and mounting , reasembled and flow is now what it should be. Thanks for your help.
