I maintain a bunch of Senior apartments. I have a tenant complaining of
low pressure on the hot side of the kitchen faucet. Cold is good and all
water in bathroom good pressures. It has new faucet and supply lines.
Aerator ok, supply seems ok..Any ideas ? Thanks.. Howie

Since the problem is only on the hot side, then the obstruction must
be in the hot alone (rust, dirt, whatever it is. It's either in the
stop valve, the supply tube, or in the faucet itself, before it joins
with the cold. Here's how to proceed. If its a two handle faucet,
shut off the water and take the hot side apart. The problem might be
obviously right there. If that doesn't work, put a rag over the
exposed hot side, and put your hand over the spout, and slowly turn on
the cold water. This will prove whether the path is clear from the
spout to the hot stem. If it's a single handle faucet, still take it
apart. You may find the problem within reach. If this doesn't work,
then the problem may be in the supply tube itself, or where it
attached to the faucet. Take off the hot supply line off and blow
through it. If it's OK, there's a chance the obstruction is somewhere
in the faucet. Try backflushing it by reattaching the supply at the
faucet, putting your hand over the spout, and forcing water through
the faucet by slowly turning on the cold water. If that doesn't work,
the problem is very likely in the stop valve itself. This will mean
you'll have to shut off the water heater inlet and take apart the
stopvalve itself, and clean it. These things are common, and it'll be
obvious once you find the trouble. If you fail miserably, write back
with the name and type of faucet.
