Burlingame’s Water, Explained
The City of Burlingame purchases its water wholesale from the San Francisco Regional Water System. That Hetch Hetchy-based supply is very soft, comfortably below the hardness level at which scale forms in a water heater.
Low scale risk does not mean no reason to soften. Burlingame homeowners who install softeners do it for zero-grain water: softer skin and hair, brighter laundry on less detergent, spot-free glassware and shower doors, and a tankless heater that never comes near its manufacturer hardness limit. We test first and give you the honest number — then you decide with facts.
Burlingame's other real water heater issue is the housing stock. Easton Addition and Burlingame Park are full of pre-war homes with original chimneys used as vents, basements or crawl-space heater locations, and gas piping sized for a much smaller load.
Those are the details that decide whether a replacement passes inspection and lasts: correct venting for the appliance category, seismic strapping, drain pan and drain line, expansion tank on a closed system, and combustion air where the heater actually sits.
For the underlying science — what calcium and magnesium do, how ion exchange removes them, and why scale wrecks water heaters — see our complete water softener guide.
Burlingame Homes We Install In
Burlingame Park and Easton Addition homes date to the early 1900s through the 1930s, with basements, original vent arrangements and tight utility spaces. Ray Park and Mills Estate are post-war and simpler. Burlingame Hills adds elevation and pressure factors. Older homes almost always need vent and gas evaluation before a tankless conversion, not after.
In Burlingame we spend our time on vent and gas evaluations for older homes — and on softeners for homeowners who want zero-grain water and warranty-safe tankless equipment in those same houses.

How a Burlingame Installation Goes
On-site hardness test
We test at your hose bib rather than quoting from a utility average, because the number decides the resin volume.
Placement walk-through
We find where the main enters, confirm drain access and a 120V outlet, and show you exactly where the tanks will sit.
Permitted installation
Loop, bypass valve, drain line and brine line installed to code, with the permit pulled under CSLB License #1008381.
Setup and handover
Metered regeneration programmed to your household's real demand, then we walk you through salt, bypass and maintenance.
Water heater work in Burlingame too
Softeners exist to protect water heaters, and heaters are our trade. We install and repair tank and tankless systems as a Navien Service Specialist and Rinnai PRO and NORITZ certified contractor — including tankless installation, repair and descaling.
Burlingame Water Softener FAQs
- Does Burlingame have hard water?
- No. Burlingame buys San Francisco Regional Water System supply, which is Hetch Hetchy-based and very soft. Scale risk is low, but many homeowners still soften for zero-grain water — softer skin and hair, brighter laundry, spot-free glass and guaranteed tankless warranty protection. We test first and show you your actual number.
- Can a pre-war Burlingame home take a tankless water heater?
- Often yes, but only after evaluating gas line capacity, venting route and combustion air. Older Easton Addition and Burlingame Park homes were built around much smaller appliances, and that evaluation happens before we quote, not after.
- Do you pull permits in Burlingame?
- Yes. Water heater replacement is permitted work and we handle the permit and inspection under CSLB License #1008381.
