Best Water Conditioner Installation in Phoenix AZ

We just failed the SRP inspection for the second time due to incompetence of Sunup.  They lie, fail to communicate, and are just plain clueless.  We paid over $44k cash months ago and still have zero benefit from our solar system because of faulty installation issues caused by the incompetence of this company.  Our next step will be to ask SRP to take them off their recommended list.  We are also considering suing for damages.
