What we see here
Nearly a third of single-family homes predate 1960
The City of San Antonio reports that 22% of all housing units — and nearly 30% of single-family homes — were built before 1960, concentrated inside Loop 410.
Original drain lines inside Loop 410 are past their service life
Below-ground cast iron waste pipe has a documented service life of 50 to 60 years. A pre-1960 home inside Loop 410 on its original line is at or beyond that, which is why so many of them show recurring backups, scale build-up and bellied sections on camera.
Very hard water, city-wide
At 15–20 grains per gallon, SAWS water sits well into the "very hard" band. That is scale in the water heater, spotting on glassware, soap that will not lather, and shortened appliance life — the reason whole-home softening is the single most requested job we do here.
Shrink-swell clay on the east and south sides
Central, east and south San Antonio sit on Blackland Prairie vertisols. The NRCS names their very high shrink-swell potential as a building-site limitation, and that soil movement is what drives slab movement and under-slab leaks.

Common questions
San Antonio plumbing questions
How hard is San Antonio water?
SAWS states that water hardness typically ranges from 15 to 20 grains per gallon, which converts to roughly 257–342 ppm — "very hard" on the USGS scale. That is hard enough that scale build-up in water heaters and fixtures is the normal outcome without softening, not the exception.
Why does my older San Antonio home keep backing up?
If it was built before 1960 and still has its original below-ground cast iron drain line, that pipe is at or past its documented 50–60 year service life. An HD camera inspection shows exactly what is happening inside — scale, corrosion, bellies or root intrusion — so the fix targets the real problem instead of clearing the same clog every few months.
