Leaking kitchen tap

SOURCE: jetted tub is on 2nd

First find access to tub,by code there needs to be access to pump motor,either built into wall or various tubs front skirt is removeable.Fill tub and run to visibly see leak,sounds like bearing assembly gaskets are leaking on pump,could possibly be a jet connection,but if it only does while running its the pump or motor assembly.Hope that helps,in the future make sure water is always above suction intakes or can lead to premature burnout of pump

You will need to shut the water line off and disconnect from the faucet. Then you will need to unscrew the nut holding the faucet in place. Take the faucet out and then you will be able to disassemble the faucet and replace the washer. Newer faucets use a cartridge with the washer built in.

you must use genuine kohler parts,if you got something from lowes or home depot that was some other brand they usually leak. also look for calcium build up inside the valve body,you can use 1500 grit wet sand paper to remove it just be carefull and dont sand too much,then apply water proof plumbers grease inside the valve body befor you install the new cartridge.
