Is Check Valve needed before Stenner?

Fired up for the first time after the Polar Vortex last week and I have a cracked check value between heater and Stenner injection port that needs replaced or removed. It was in place because the current injection point used to be a puck feeder. Can I just eliminate the check value? TIA

Col,

You only need a check valve between a tab feeder and a heater.. With a Stenner, or a SWCG, no check valve is needed..

There should be a check valve on the Stenner line, which is part of the Stenner install, and nothing to do with the check valve before the heater.

Thanks,

Jim R.

Was thinking that was the case, and the hoped for answer. Thanks!

I think it’s a good idea to replace that check valve. It will keep any unwanted chemicals from backing into the heater. $50 part could save you fr replacing your heater prematurely. Seems like a good investment.
