Water Heater Check Valve
Hi, I am about to replace my Suburban SW6D water heater and I noticed the hot water outlet had a check valve installed but the cold water inlet did not. Should there be a check valve on both inlet...

downside of the single check valve vs. no check valve and a two valve bypass is that with a single check valve, usually the cheapest available, the valve is usually not a constant restriction and when you are in the shower and turn down the volume, you may get a blast of cold water. Our trailer did that and when I pulled it out and put in the two valve bypass problem went away.
