We sell and install mainly Water Tec water softeners. The company is located here in Tucson, AZ and have a very good reputation. If there is a problem with the softener then we can get parts and service to you right away. With other brands there may be a long wait period.
The most common Water Tec Water Softener we provide and installed will cost only $1130 installed. That includes haul away of your old water softener.
If you prefer to purchase your own water softener and already have a loop in place, the the cost of installation with parts is $170-$220 depending on the size loop you have. Most loops are either 3/4 in or 1" copper.
