New-Home Plumbing Walkthrough: What to Inspect Before You Close

Before signing on the dotted line, it’s essential to know your new home’s plumbing is up to par. Even brand-new builds in Central Texas can hide issues that turn into headaches after closing. Use this checklist to inspect plumbing systems before you finalize your purchase, whether you’re buying in Austin, Round Rock, Hutto, Kyle or Leander.

Your Pre-Close Punchlist

• Main shutoff & cleanouts: Locate the main water shutoff valve and exterior cleanouts. In Round Rock, Hutto and Kyle new builds, these are often near the curb. Ensure they’re accessible and labeled.
• PRV setpoint: Check the pressure reducing valve (PRV) is set around 60–70 PSI and confirm the expansion tank is properly charged.
• Water heater: Verify correct sizing, temperature setting (120–125°F), venting, and condensate routing. For tankless units, confirm proper gas line sizing and condensate drains.
• Fixtures: Inspect supply stops, drain seals, trap arms, and aerators for leaks or debris. Run water at full flow to check for consistent pressure.
• Toilets: Ensure they are securely mounted, don’t rock, and refill quietly. Check for wax ring leaks at the base.
• Recirc timers: In Lakeway and Leander homes with long runs, a smart recirculation timer can reduce hot-water wait times.

Test Every Water Path

• Turn on all faucets (hot and cold) and appliances at full flow. Listen for pressure drops or sputtering.
• Fill and drain tubs and sinks to ensure proper drainage and that traps are leak-free.
• Inspect dishwasher and ice maker supply lines; braided stainless steel hoses are ideal for longevity.

Ask the Builder

Request documentation on fixture models, PRV and expansion tank specs, water heater manuals, and backflow device details. Knowing exactly what was installed helps with future maintenance and warranty claims.
