★ San Antonio, Texas
The PF-12 trenchless pipe pulling system lets San Antonio plumbing contractors replace water service lines from two small access points, with no continuous trench and no restoration bill. Built in Tennessee by working plumbers. $12,995 + freight.
★ The Market
40% of the homes in San Antonio were built before 1980, and the median home was built in 1986 (U.S. Census, ACS 2024). Service lines that age are reaching the end of their life, and every one that fails is a replacement job.
SAWS reported more than 600,000 service lines in September 2024, with about 150,000 unknown on both sides and another 235,000 known on the utility side only. SAWS offers free service-line inspections for registered homes built before 1989.
SAWS lists copper, plastic, and some iron-based pipe among non-lead lines, and flags galvanized and lead.
Traditionally, each of those jobs means trenching from the meter to the house and paying for lawn, driveway, and irrigation restoration. The PF-12 lets San Antonio contractors pull the new line through the old path instead.
★ The Ground
Bexar County has high-clay shrink-swell soils in the middle of the county, thin limestone soils on the north and west sides, and sand over clay to the south.
Expansive clay is slow to trench and hard to restore cleanly, and a long backfilled trench can settle for months. Pulling the new line through the existing path leaves the yard largely undisturbed.
Trenching through shallow rock means hammers, rock removal, and crushed-rock bedding before you can backfill. With trenchless pipe pulling, the new line follows the path of the old service, so open excavation is limited to the two access points.
Slab foundations are the norm in the West South Central region: 97.9% of new single-family homes built in 2024 sat on a slab (NAHB, Census data). The PF-12's under-slab capability pulls new PEX-A beneath the slab from two small access points, without breaking up the floor.
