low water pressure

[billsinca]

ok, have had my 2005 georgetown 370 for about a year. We have not had a problem in the kitchen sink with water nor in the toilets or sinks but the shower is ridiculously weak. I out one of those oxygenshower heads on and no improvement. Any suggestions?
thank you in advance

There's a small flow control orifice where the shower hose connects to the C/H faucet. See if that opening is restricted. Besides that can you connect a small air compressor to the same joint, 20-30 psi is plenty. Open the cold water low point drain and blow the line back wards. There really is no other restrictions to the fresh water piping to the shower. Just on a chance have you taken the faucet apart? Remove the handles and take out the stem assembly. check for calcium build up, but I doubt it.

Have you checked or changed the inline water filter, I replace my filter at least twice a year but we use it a lot.

A clogged filter will reduce pressure at all outlets.
I would look for construction debris (or a calcium/anode nodule) in the valve body of the affected faucet.
