Just had our five year checkup on our whole house system. Everything is just fine!!! I love how they show you water tests before and after they turn the system on and then when it’s off. No chlorine and junk in our water! Best investment ever! Our whole house system is attached to our main so bathing, watering, drinking… every drop is filtered without nasty salt and other garbage. Eco friendly and money saving our water is like Evian from the tap!
