I bought a watts 200psi dial pressure gauge from home depot and hooked it up to my basement washing machine hookup. The gauge also has what i think is called a lazy hand. Well! 90PSI on the cold!, i few less on the hot. Should i worry ? Do i have to call and make a stink about this??? The needle vibrated at 80 when i ran the tub and upstairs sink. I'm not sure how fast acting the needle is, but shutting off sinks agressivly made the needle record 100psi. Very aggressively 105, and turning the tub off in a very violent and contrived manner registered just under 120. My shower head is probably a safe 80psi due to height. Im going to replace my washing machine hoses with the fluidmaster no-burst kind. Maybe add an arrestor too. Dont want a flood. The pipes have always been very very noisy her but they don't bang or thud when stopping the water. I have seen my washer hoses jump some though when my neighbor turns something off. What to do what to do..
