I have a pretty bad situation at my place. I have a leaky shower faucet which has gone from drips to a steady stream. I calculated the flow at .3 gallons per minute. My very old home has no private shut off valve for the water. I tried to shut the water off at the meter, but the valve was very tough and I didn't want to force it, break something, and be liable.
I've noticed that the water coming out of the faucet is pretty hot. So, I tried shutting off the valve supplying cold water to my heater. The amount of water leaking from the bathroom faucet reduced significantly. Is it safe to simply shut off the cold water supply to my gas heater or will it cause problems with pressure? Will water come out of the pressure relief valve at some point?
This is a temporary measure until I can have the water shut off by the water company or plumber. For now, I've left it on.
