open loop geotherm question
we have a customer with an open geotherm system. the water is pumped from the same well that supplies domestic water to the home. the water goes through one six ton heat pump unit, and then gets dumped into a field in the back of the property. this is older home, and this system has been grandfathered in to the new local ordinances. there is a testable backflow preventer where the water enters the heat pump unit. is there any reason that this water that goes to the heat pump unit, go through the water softener first? the customer goes through a ton of softener tablets through the year,and would like to install a bypass line around the softener to the heat pump unit. I am unsure if this would create more problems then it is worth, if the raw ground water fouls the tubes of the heat pump unit. the only suggestion i would have would be to install the bypass line, and keep an eye on the ph level to ensure it stays between 7-9 going to and from the heat pump unit. these systems are very rare around here so any suggestions would be much appreciated. thanks to all
