water heater check valves

[rick_od]

This weekend when camping I noticed a water hammer sound from the in check valve on the water heater when I was running cold water.
Has anybody removed these check valves and just installed a pipe nipple?? If so, have there been any side effects (ie. warm water from the cold faucet). I would like to remove them and install on/off valves for winterizing but am wondering about side effects.
Thanks

Rick,
My valve failed shut and I could not get any hot water. I had them replaced at CW and all they had were plastic valves, so now it sounds like a Kazoo when we run hot water, I purchased a set of brass valves and will eventually replace the plastic. If I could have found shut off valves, I would have put them in, but we were on the road and had to take what we could get.
They are a bear to get to on my coach.
Good Luck,
SeaRay

You apparently didn't read LK23's thread?

I have read that the only reason for the HWH check valves is for winterization. That being said, because I have already replaced my valves once and now they are vibrating when in use, I would like to remove them completly and relocate my winterization shutoff to behind the HWH.
I am concerned that having no check valves will allow hot water from the HWH to creep into the cold lines.
Has anybody removed their check valves completly and if so what were the side effects???
Thanks

I've taken mine out. We're in it fulltime and I see no difference with or without.
