Water heater check valve question
A while ago I asked a question in regards to a noise I had in my water heater, and the general concensus was it was the check valve. Now I want to remove it and replace it with a valve. My problem...

Hi,
I would leave the valve in place, and install a second check valve in a convenient location. To bad to find that out after spending a hour to get the darn water heater out of the RV. Yet it will help me to know that in advance.
A swing check valve that is mounted so that closed is down, and the arrow on the side points straight up will make sure it closes the best - even under low back pressure.

OP has the same problem I had with mine, a noisy check valve which sang a horrible note when hot water is drawn.
The only fix is to remove or if very lucky remove the offending internal parts..
My vote is to remove the valve which is going to require removing the insulation so you can get a pipe wrench close to the tank..
Breaking out the internal parts is a risky idea which may leave broken plastic bits in the tank..
If the valve body breaks of then OP can use the internal pipe extractor I posted to remove the leftover pipe stuck in the tank threads.
The key here is getting a pipe wrench as close as possible to the tank which should reduce the off chance of breaking the valve body.
Your suggestion of a swing valve is dead on, I installed mine on the floor and used a short piece of Pex from the valve to the tank.
No more screaming check valve.. Priceless :D
