My faucet on my bath top was leaking.It is a three handle system. I took the stems out and replaced the O-rings. Nothing is leaking anymore, but when the diverter is insalled, part of the water still flows out the tub spout when it is diverted to shower. The diverter parts are fine.
Is there a specific way, position, how the diverter has to screwed in.
Thanks for your help
