The water does not completely divert to the showerhead from the faucet. There’s the usual little pull-up thingy on the faucet to divert the water. enough, I replaced the faucet with a cheap Wal-Mart one, and that didn’t help at all. Next I bought a more expensive faucet from Lowe’s, and that didn’t help either. I take it apart and can manually, with ease, make the diverter move as it’s supposed to. There is sufficient water pressure, Please help
