    I replaced an old, leaking American Standard tub/shower set with a new American Standard #3275. Since the replacement, the tub/shower flow, both hot and cold, is just 1 gallon per minute. Takes FOREVER to fill the tub, 5 minutes to fill a 5-gallon bucket. When I pull the valve stem and let the pipe flow open it blasts out about 8 - 10 gallons per minute - much like Old Faithful. I'm suspecting the valves are too restrictive. Went to Home Depot, where I purchased the fixture. They couldn't explain the lack of pressure nor do they stock replacement parts. Called American Standard and they said the new valves are obstructed with debris. They are sending me replacements valves, which is nice. However, I completely disassembled the valves I have and they are as clean as a whistle nor is there debris backed up behind the valves. I need plumbing advice. Any and all appreciated. Thanks. pk

    we would have to be there to check it out. The shower head could be restrictive, but that would have absolutely no effect when filling the tub. As an aside, I try NEVER to use American Standard valves.
