We start every water softener installation by testing hardness levels at multiple points in the home. In Gaithersburg homes we check inlet pressure and existing pipe material before cutting into supply lines. Montgomery County requires backflow prevention on all new softener units so we install a code compliant dual check valve on the bypass loop. Older homes in Kentlands and Lakelands often have galvanized lines that we replace with copper or PEX during the same visit to prevent leaks after the softener goes online.
The unit sits on a level base we pour if the floor slopes. We run a dedicated drain line to a standpipe or floor drain and install a shutoff on the brine tank fill line. In humid subtropical climate with four distinct seasons we insulate the brine tank and control valve to stop condensation during summer months. We program the control head for the exact grain capacity and local water hardness recorded at the kitchen tap before we leave the property.
After startup we run a manual regeneration cycle and check for leaks at every joint. We verify the bypass valve operates correctly and label the inlet and outlet for future service calls. Homeowners in Quince Orchard and Montgomery Village receive a written bypass procedure they can follow during power outages.
