Buying a home in Las Vegas, Henderson, or Summerlin is a major investment, and plumbing is one of the most expensive systems to get wrong. A general home inspection covers plumbing at a surface level — this checklist goes deeper, covering exactly what to ask, check, and request before you close.
Before You Make an Offer
- Ask the age of the water heater — Check the manufacture sticker date. In Las Vegas, Henderson, and Summerlin, 8+ years old means it's likely near end of life due to hard water wear.
- Ask about pipe material and age — Especially important for Summerlin homes built in the early-to-mid 1990s (polybutylene risk) and older Las Vegas or Boulder City homes (galvanized steel risk)
- Ask about known leak or repair history — Sellers are required to disclose known issues, but ask directly and in writing
- Check for a water softener or filtration system — If present, ask about maintenance history; if absent, budget for one given valley-wide hard water
During the Walkthrough
- Run every faucet — Check water pressure and how quickly hot water arrives at the farthest fixture from the water heater
- Flush every toilet — Listen for running after the tank refills, check for wobbling, look for water at the base
- Look under every sink — Check for moisture, staining, or a musty smell — signs of a past or current slow leak
- Check the water heater area — Look for rust, moisture, or corrosion around the base and connections
- Note the water pressure regulator — If visible near the main shutoff, ask its age; PRVs typically need replacement every 7–12 years in Las Vegas
- Look for unusual cracks in flooring or walls — Can indicate a past or active slab leak, especially relevant in Las Vegas, Henderson, and Summerlin's expansive soil
Get a dedicated plumbing inspection: A standard home inspection in Las Vegas, Henderson, or Summerlin typically spends only minutes on plumbing. For homes over 15 years old, a separate plumbing-focused inspection — including water pressure testing, water heater evaluation, and a sewer camera scope — gives you real leverage in negotiations or the confidence to move forward.
Red Flags Worth Walking Away From (or Negotiating Hard On)
- Confirmed polybutylene pipe with no disclosed re-pipe plan — increasingly an insurance issue in Summerlin
- Active slab leak or undisclosed repair history
- Sewer line showing significant root intrusion or a collapsed section on camera
- Water heater original to a home 15+ years old with no maintenance records
- Visible mold or water staining the seller can't explain
What to Request From the Seller
If issues are found, you have options beyond walking away: request a price reduction reflecting the repair cost, request the seller complete the repair before closing, or request a credit at closing so you control the repair with your own trusted plumber. Having a written, itemized quote — which Smith's provides — strengthens your negotiating position significantly.

Frequently Asked Questions
Should I get a separate plumbing inspection when buying in Las Vegas?
Yes, especially for homes over 15 years old. A standard home inspection covers plumbing only briefly. A dedicated plumbing inspection includes water pressure testing, water heater evaluation, and can include a sewer camera scope — giving you real information before you close.
What plumbing red flags should I watch for when buying in Summerlin?
Confirmed polybutylene pipe (common in homes built early-to-mid 1990s), an undisclosed slab leak history, an aging water heater with no maintenance records, and any unexplained water staining or musty smells under sinks or in closets.
Can I negotiate on plumbing issues found during a home purchase?
Yes. Common approaches include requesting a price reduction reflecting the repair cost, asking the seller to complete the repair before closing, or requesting a credit so you handle the repair yourself with your own plumber. A written, itemized quote strengthens your position.
How much does a pre-purchase plumbing inspection cost in Las Vegas, Henderson, or Summerlin?
Cost varies by home size and whether a sewer camera inspection is included. Smith's provides upfront pricing before scheduling — it's a small cost relative to the negotiating leverage or peace of mind it provides on a home purchase.
