: : Our upstairs shower is lacking hot water pressure.
: : It is a very lazy stream and is not very hot.
: : On the other hand the upstairs faucet works great.
: : How or what could be the problem and what could the remedy
: : be. Any info would help
: : Thank you

: Is this only a shower? or a tub and shower? if its a tub how is the flow out of the out of the spout? if it is a shower is there a difference in flow between hot and cold? If not the shower head if clogged.
: (can you give me the manufactures name)?

One reliable and easy trick to try to improve h/w pressure at an older (pre anti-scald, pressure balanced) shower fixture is to backflush the lines. Shut off the incoming cold water supply to the hot water htr. and open the laundry tub hot water tap or the relief valve on the water heater(some hot water will come out--be careful). Remove the shower head and put a 1/2" i.p. cap on the shower arm in its place. turn on the hot water and the cold water for the shower at the same time or if it's a single handle faucet, put the handle to the middle, wide open, and the cold water will now run backwards thru the hot water piping and the laundry faucet, carrying the sediment which is probably causing the blockage. let it run for 5 or 10 min, then gradually turn the hot water on again, but leave the cold running until you have all the water back up.
