The hot water side is mostly affected.In the kitchen it runs well over time period then
starts to gradually lessen.When I go under the crawlspace and tap the(kit) lines where the
elbows meet the strangest thing happens,almost full water pressure.I am thinking
to repipe a section(hot) with galvanized since it is a small run.what size wrenches do I
use and in what manner when loosing or unscrewing? Back to the bathtub,I have been
able to get enough water flow by taking off the stem trim and spout and tapping
cautiously but now my time is limited.I only get a stream that is slowing up daily
and no amount of tapping produces any increase.The cold is fine.Again,is it in
the valve stem and do I need to flush it out or is it time to take off a line or section
and repipe? Thanks for help
