Javi... To stop the cold water "blast" all that is needed is to install a check valve right at the "hot" water supply line going out from the heater?
I have a 2016 Cougar 303 and it has NO check valves but does have one by pass valve like the photo above that is posted. I do not want to install any valves that requires cutting the plastic water lines. I have a small 1/2" brass flapper type check valve that will fit on to the heater outlet side and just need a short nipple to reconnect the plastic supply (hot water side).
Is my understanding of what you are saying correct?
THANK YOU......
