The plumbing you install during construction is the hardest to change later, which makes getting it right the first time essential. From the underground rough-in beneath the slab to the final fixture trim, every joint and every line has to meet code and match the builder’s schedule. Jennings Plumbing LLC provides new construction plumbing in Tyler for custom homes, spec builds, and additions.
Schedule slips are expensive, and plumbing sits on the critical path at several points in a build. We staff our crews to hit your rough-in and trim dates, flag any material lead time early, and set underground lines with proper bedding so Tyler’s expansive clay soils do not stress the joints after the slab is poured.
We lay out and install sewer and water lines to the engineered plans, set proper slope on every drain, and pressure-test the system before the concrete crew arrives. A missed measurement under a slab becomes a costly jackhammer repair, so we document and photograph the layout for inspection.
Once framing is up, we run supply and drain lines through the walls, set tub and shower valves, and install vent stacks. We size and run gas lines for ranges, water heaters, and fireplaces, and set tank or tankless heaters to match the home’s demand. Each stage is pressure-tested before walls close.
At trim-out we set and connect toilets, faucets, sinks, and water heaters, then test every fixture for leaks and drainage. We walk the home before the final inspection to catch anything that needs adjustment, so a closing date is never held up by a failed plumbing sign-off.
Licensed and insured in Texas, we work to the adopted plumbing code and pull the permits the City of Tyler and Smith County require. Our bids are detailed, so you know exactly what your new construction plumbing scope includes, and we treat your reputation with the homeowner as carefully as our own.
Yes. Most of our new construction plumbing work is done in partnership with general contractors and custom builders. We slot into your schedule and coordinate with the other trades to keep the build on track.
We install and pressure-test all underground lines before the pour, with proper bedding and slope. Tyler’s clay soil moves, so correct support and testing up front prevent expensive repairs later.
We pull the required permits and schedule every inspection as part of the project, then make sure each phase passes before the next stage of construction continues.
Absolutely. We size supply lines, drains, gas, and water heating to the home’s fixture count and demand, so pressure and hot water keep up even in a large multi-bath build.
