Water Softener in Reston, VA

Reston at a glance

Reston's planned villages grew from the 1960s on, and the median home was built around 1983, so plenty of houses still have their first water heater closet layout and, sometimes, an aging softener. Water comes from Fairfax Water's Potomac and Occoquan plants. Neither source is soft, and the reading at your tap shifts through the year.

What to do now

1. Test at the tap. A simple hardness strip or a kit gives a reading in grains per gallon. Compare it with Fairfax Water's published range.
2. Look at the water heater. Popping, slow recovery or flakes at the drain valve point to scale already inside.
3. Find the main. Note where the water line enters and whether there's room for two tanks and a drain nearby.
4. Check an existing unit. Look for salt bridging, a stuck timer, or water standing high in the brine tank.
5. Decide on taste. If the spring switch to free chlorine bothers you, plan for a carbon stage too.
6. Check HOA rules. Townhouse and cluster associations sometimes restrict outdoor equipment or exterior penetrations.

Symptoms and likely causes

Cost factors

Price follows the size of the system, the hardness setting, and the plumbing work needed to fit it. A pre-plumbed loop and a floor drain close by keep the job simple; cutting into the main in a finished basement, running a longer drain line or adding a carbon tank adds parts and time. Removing an old unit and replacing corroded valves around it also counts. If new piping is part of the job, Fairfax County Land Development Services is the permit office for Reston; it exempts like-for-like replacement in the same location. Your plumber can confirm whether a permit applies before the work starts.
