A,

If you don't have a tablet feeder, you really don't need a check valve as when the SWCG is off, it is off.. there is nothing to feedback into the heater like there would be if you had a tablet feeder..

The valve you picked would work if you have 1.5" plumbing.. If you have 2" plumbing, you would be better off with a 2" x 2.5" valve..

Thanks,

Jim R.
