I turned off the main water valve outside the house to change the kitchen hot
water shut off vlave because it keeps dripping water. I relieved the
pressure by opening the water in the bathroom closest to the kitchen. When I
removed the valve hot (warm) water kept coming out. I put a bucket waiting
for the presure to finish but it would not stop. Tried to replace with the new
one but the water would not allow me to finish the job. had to put back the
old one. Water still drips slow but i am still confused on why the water
keeps comimg out after shuting off the city main valve.


1) Any water in the system that is above the valve you removed will
run out by gravity. That means if you are on the ground floor, all the
pipes on higher floors will drain. If the water heater is on the same
floor as you, it will drain down to the level where you opened the
line. Try shutting off the water heater valve and see if water runs
for less time.

2) When you shut the city valve did the flow indicator on the meter
completely stop?



That's a good point, it might not be from the main valve. He could
open a faucet at the high point and another one at the faucet he;s
working on or below to drain it out. Usually thought that seems to
stop on it's own in a short time, without all the water running out.
Also, depending on what you're doing, eg replacing a cartridge, it
may not matter if there is still a slow flow.
