Winterizing and the Water Heater by-pass:



·

</span></span>The water heater has been drained.



·

</span></span>The two water heater valves have been turned

(one at the water input the other at the output port )



·

</span></span>I have the pump intake in a bucket of

antifreeze.



·

</span></span>The pump is on and up to pressure.



·

</span></span>All of the cold water faucets have been purged

with antifreeze.



·

</span></span>None of the hot water faucets will produce a

flow.



·

</span></span>Turning either of the water heater valves allows

antifreeze to fill the water heater.



I finally ran a tube between the low point drain tubes and

opened both drain valves. The pump cycled a lot but I did manage to purge the

hot water lines.



Do I need to install an aftermarket by-pass? I thought there

was a check valve on the water heater to prevent back flow into the output

line.



Confused????????.. Kamper Dave

It should have a bypass with a valve in it that has to be opened to let water through.

Should be a short section of piping between the water heaters hot and cold water lines that has a valve in it. The handle of the valve needs to be in the vertical position for by-passing the water heater.
