People assume new means perfect. It usually means new — and new work still has defects, just different ones than an old house. Handover checklists in new homes repeatedly catch leaks, running fixtures, wobbly fixtures, and shutoffs that were never tested. The difference between a person who catches those things and one who lives with them is a plan: three looks, not one, with the plumbing questions for a new build asked at each visit. In fast-growing communities like Harvest Point and June Lake, where phases sell quickly and several crews work across different sections, that plan matters more than ever — check per phase, and never assume one crew's practices describe every home in the neighborhood.
Weeks 1–8: Open Walls to Boards
The build calendar starts with the frame, and the first plumbing moment arrives sooner than most people expect. After the frame is up and before a single board goes on, the pipework goes in — supply, waste, and vents, all visible, all reachable. This is the only week when a misplaced drain or a missing shutoff is a ten-minute fix. Once the walls close, the same fix is a wall opened, patched, and repainted. If you are buying during the build, ask the crew for the open-wall date and whether you can walk the house that week. Bring a tape measure and the plan: check that every fixture sits where the plan says, that shutoffs are where you can reach them, and that the runs are protected where they pass through studs.
- Pipe sizes and paths. Are the supply runs sized for the fixture count, and routed sensibly to each bathroom, the kitchen, and the laundry?
- Drain pitch and vent layout. Drains need the right pitch to carry waste without pooling or running dry, and every fixture needs a vent path. Pitch and vent errors are hidden after the walls close and miserable after move-in.
- Pressure check. The supply system should be pressure-checked before it is buried behind boards. A check that holds tells you the joints are sound; a check that drops tells you where to look.
- Pipe guards. Steel plates should guard every place a pipe passes through a stud where a board screw could find it. This is a small, cheap detail with an outsized payoff.
- Cleanout reach and fixture spacing. Cleanouts should be reachable, not buried. Fixture spacing should match the fixtures actually ordered, not a generic plan.
If you are buying during the build, ask the crew when the open-wall inspection happens and whether you may have your own inspector present. A municipal or county inspection is not the same as a buyer-side inspection: the first checks code minimums, the second checks your home. Tennessee's home-inspector guidance explains what a licensed home inspector does and does not cover — useful background before you hire one.
Weeks 9–16: Walls, Trim, and the Walk-Through
The second moment is the last walk-through, days before handover. Run every fixture yourself — do not watch a representative run them. Turn each faucet on full and off again, flush every toilet twice, run the shower until the water is hot, fill each tub and drain it, and open every cabinet to look for leaks. A fixture that gurgles, a drain that clears slowly, or a toilet that rocks is a punch-list item, not a mystery. Write it down, photograph it, and get it on the list before you sign — after handover, the same item becomes a negotiation.
While you are walking, look at the water heater: it should be secured, connected, and producing hot water at a reasonable temperature. Ask where the shutoff is, where the drain pan empties, and whether the unit is the size the plan called for. A heater that is too small for the house will announce itself on the first morning four people shower — and by then the crew has moved on. The walkthrough is the last moment the answer is free.
Year One: The Check Everyone Forgets
Most company guarantees run about a year, and the year-one mark is the safety net owners say they wish they had used. By then you have lived through every season: a summer of full-house showers, a winter of cold snaps, a spring of rain. Walk the house again with the same eyes as the first walk-through — every faucet, every toilet, every cabinet — and write down anything that drips, sticks, whistles, or wobbles. That list, sent before the first year ends, is the difference between a free fix and a bill.
Between handover and that year-one mark, keep your own log. Note every leak, every slow drain, every noise, and every fixture that behaves differently than it did at handover. Dates matter: a stain that appeared in February and a second one in April tell a story a single visit cannot. The log is also your evidence — a company responds to a dated list far faster than to a vague complaint, and a future buyer will read it as proof the house was watched.
The Upgrade Window: Before or After Handover
Early failures of entry-level faucets, toilets, disposals, and valves are a recurring complaint in new homes — not because the parts are defective, but because they are the cheapest parts that meet the spec. The question is not whether to upgrade; it is when. Swapping parts before handover means the crew does the work and the upgrade is in the mortgage; swapping after means you pay cash and live through a second round of work. Either way, decide with the calendar in mind: the parts you touch every day are the ones worth upgrading first.
Also clarify responsibility before you need it: company coverage versus maker coverage versus your own maintenance. A dripping faucet early in year one might be a company item, a maker item, or a wear item — and the answer decides who pays. Ask the company, in writing, which bucket each system falls into, and keep the answer with the handover papers. The worst time to learn the answer is the day something breaks.
Quick Answers
Is a second set of eyes worth it on a new build?
In our opinion, yes. A municipal check covers code minimums; a buyer-side inspector measures your home against the plans and the defect list, including the pipework details a code check may not cover.
What do I do at the last walk-through?
Work every fixture yourself: faucets on full and off, every toilet flushed twice, showers run hot, tubs filled and drained, cabinets opened for leaks. Blue-tape every defect and date it on the punch list.
What happens near the end of year one?
A buyer-side look near the end of the first year, after the house has lived through all four seasons. Shifts, loosened joints, and finish defects that the walk-through missed show up by then.
What belongs on the blue tape?
Anything off-plan: a leak at a connection, a wobbly fixture, a slow drain, a noisy pipe, a shutoff never tested, a defect-list item left unfinished. If it drips, wobbles, sticks, or whistles, tape it.
A new home is a beginning, not a guarantee. Three looks, a written defect list, and a first-year log turn that beginning into a home whose pipework you have actually checked — which is the only kind of new worth paying for. Our new-build plumbing service in Spring Hill can walk any of the three looks with you, from open walls to the year-one check.
