Water heater check valve

I always winterize by blowing out lines then putting enough propylene glycol in the water tank to properly run enough through my wash machine. I went to bypass the water heater and when I turned the pump on I could still hear something filling in the heater tank....
Quickly realized the check valve was leaking.
Had I not happened to hear that I would have wondered where all my antifreeze went to after completely filling the water heater...
My rig is 15 years old something to think about replacing that check valve....

If you blow out, why do you not blow out the Washer also?????? What you do is, install a 1/2 gallon of antifreeze in the washer, set the water temp to Warm/Cold. Then when blowing out start a wash cycle. You will hear the 2 water valves blow air after the lines are purged and when the dump cycle activates, the antifreeze will go thru the drain pump. A lot easier. Doug

Thanks Doug Iโ€™ll consider that. I was just following manufacturers instructions.

If you have access/room get RID of that check valve and install a manual shut off valve

Your water source must be pretty good for that check valve to have not caused issues before
Is it time for your medication or mine?

My rig is 10 years old and I am on my 3rd check valve. Yours did well.
