I have an odd problem. Whenever I flush my toilet I hear a loud BANG in the basement and for some reason i lose Hot water from the tap. and it stays off until the toilet tank fills up. The cold water works fine(pressure goes down a bit and goes to regular pressure when tank is full).
It seems like the water heater is being starved. But what about the Bang. I've heard water hammer occurs when water is being shut off, but this is happening when the tank starts to fill.
I recently remodeled this bathroom and replaced all the fixtures. So everything is brand new. The plumbing itself is all the same.
I hope some one has an idea on how I can fix this.
