Installers were pleasant, courteous, and professional. Initially analyzed the best way to install water softener and discussed installation locations with me. After softener was installed, checked the system and immediately discovered that water pressure was lost. They checked all connections and found that there was an issue with main water shutoff valve, which may have occurred when water was shut off just before installation. Installers had a replacement valve on the truck, and replaced the valve at no additional charge. Problem solved and system is great so far…enjoyed my morning shower with softened water!
