Need Hydrostatic Testing in Southlake, TX?
Hydrostatic Testing Services in Southlake, TX
Buying or selling a house in Southlake? Odds are the inspector or the buyer’s agent is going to ask for a hydrostatic test on the sewer line. We run them constantly out here — Carillon, Vaquero, Timarron, Stone Lakes, you name the neighborhood and we’ve probably tested a house on that street in the last twelve months.
Pre-Purchase Sewer Testing
Southlake homes tend to be larger, on bigger lots, with mature oaks and pecans that have been working on the sewer laterals for decades. Add the expansive clay underneath and you get the perfect setup for separated joints and slab leaks that don’t show up in a visual inspection. Hydrostatic test catches what eyeballs can’t.
Accurate Pressure Testing
Here’s how the test actually goes. We pull the cleanout cap closest to the house, drop in an inflatable test ball at the city main side, fill the line with water until it stands at slab level, then watch the level for 15 minutes. Drops more than the allowable inches, you’ve got a leak somewhere in the system. We write up a one-page report with the pressure reading, the time, and a clean pass/fail you can hand to the title company.
Serving Southlake Home Sales
Pricing: $375 for a standard Southlake test, same-day report. We can usually be out the next morning if your closing’s tight. If the test fails, we’ll quote you (or the seller) on either a static test to narrow down the location, or a sectional isolation to figure out exactly which run is leaking.
