What a written spec should include
Last reviewed: September 12, 2026
A useful water-treatment spec starts from the city’s plant hardness, not a surprise kit on the porch. It states capacity math, media, disinfectant handling, bypass, and who holds the license. Georgetown Home Services does not sell equipment or book installs.
Hardness input
The spec should name the treatment plant assumed for the house and use that plant’s published milligrams per liter and grains per gallon. Conversion between those units uses 17.1 mg/L as CaCO3 per grain. Confirm the plant with Georgetown Utility Systems if the address is near a boundary.
Capacity math
Daily household water in the math we publish is 75 gallons per person. Occupancy and regeneration settings belong in the written spec. If those inputs are missing, the grain capacity is a guess.
Media, bypass, and license
- Resin or other media named, including chloramine handling if a softener is proposed.
- Bypass and untreated hose bibs called out so irrigation and drinking preferences are explicit.
- Installer license class stated: Water Treatment Specialist and/or plumber, as the work requires. Ask to see it. We do not invent license numbers.
Not affiliated with Georgetown Utility Systems or the City of Georgetown. We do not perform door to door tests. Installation, if any, is by a separately licensed Water Treatment Specialist or plumber.
