I have an old (unknown age, but at least 12 years) American Standard tub spout with a wall diverter that leaks far more than I would expect when the water is directed to the shower. It seems like it is leaking enough to decrease the available pressure to the shower. Is there any way to tell how much it is supposed to leak/drip? Are there any spout diverters that do not leak or drip as part of the design?
Thanks in advance for any useful responses.
