very low shower head flow
Hi All-
I have a 4 year old, single handle tub/shower fixture that won't allow the shower head to flow with reasonable flow. This just happened a couple of days ago. The tub flow is fine. When diverted to the flows fine for a few seconds, then...thump...and the shower goes to MINIMUM flow. Turn it off and do it again....flow is OK for a few seconds then...thump (pipe thump) and the flow again goes to a fast trickle. Something in the valve is making a 'banging' noise and the flow to the shower almost stops. It does this in cold only too (valve position), so it probably isn't the anti-scald (although the reduced flow) . When the 'bang' and reduced flow occurs the tub does not have flow, so it isn't being diverted back to the tub. In fact, I can set the diverter (midway) so that the tub and shower both work and the shower pressure is fine. And with both running, the temperature is fine, hot or cold. It only does it when I divert MOST of the water to the shower head.

If you have copper pipes, possibly a loose piece of solder broken loose? try taking the showerhead off and running the water full force. If that doesn't work, you'll prolly have to disassemble the valve. :(

loose solder?
Thanks....took the shower head off first. No change. It seems the diverter is 'slammin' into place adn restriction the flow to the shower head. It is a distinct 'pipe hammer' when it clicks into place.

Name od valve would help, and the way you divert the water would help also.

The fixture is a Pegasus (Home Depot), single handle tub/shower unit with the diverter on the face plate. (vice on the tub spigot)

Replace the diverter parts on the valve, that sounds like the place to start.

shower head
Thanks for the site. And thanks to all who replied. It turns out the washer had disintergrated and was stopping the flow....varying each time.
