    Hello, i need help with the placement of a water softener with my open loop geothermal system. Will the plumbing setup i sketched in the attached thumbnail image work? Or will I need some sort of check valve at the softener/Geo split? Any help is appreciated.

    It looks ok, but why do you need a water softener? Hard water from your well (I assume the source is a well)? If so, is the water quality good enough so as not to plug up the heat exchanger on your geo unit? Are the total dissolved solids (TDS) within the water quality spec of the geothermal unit?

    Thanks for the info. We are constantly cleaning faucet heads,shower glass,etc from bad calcium deposits. The water source is a well. Not sure if the water was within specs when installed as we are the second owner. When we moved in, I replaced the water heater which was over have full of calcium. Granted the Water Furnace premier 2 is now 20 yrs. Old and still kickin. Former owner said he only changed sediment filters and cleaned the Geo's air filter regularly, no other maintenance or repairs.

    Hi an welcome! If you calculate the gallons per day used by your geo system and compare to the specs for water softeners you will soon realize that the unit needed would be as big as your house.

    Hello, with my sketch, I was not intending to soften the water that was going into to geothermal unit. I want to soften the water going to the fixtures of the house only.

    I'd consider ensuring provisions to isolate the geothermal from softerner to ensure you will have future opportunity to circulate acid through geo to clean coils without risking drinking water contamination
