01 — Your Home & Plumbing
Larger homes have more pipe length, more fixtures, and higher exposure to plumbing issues.
Slab foundations in Central Texas significantly increase repair costs — pipe access under a slab can add $3,000–$8,000 to any remediation job.
More bathrooms means more fixtures, more pipe connections, and more potential failure points.
years
Galvanized steel lasts 20–50 years. Copper lasts 50–70 years. PVC can last indefinitely with proper installation.
No issues — that's a great sign.
Plumbing that has never been inspected often has slow leaks, corrosion, or pressure issues that go undetected for years.

$
Check your last utility bill. The average Texas household pays $60–$120/month. Higher bills can signal a hidden or active leak.

Step 1 — Cost of Non-Functioning Plumbing (Annual)
When plumbing is not working properly — no hot water, active leaks, no pressure — homeowners incur real daily costs while waiting on repair. We apply a conservative floor estimate of $900/year — approximately $75/month — covering temporary solutions, emergency call fees, bottled water, laundromat costs, and comfort disruption. This figure is intentionally conservative. A slab leak or loss of hot water in a household with multiple people typically costs far more.
Operating Cost = $75/month × 12 = $900/year (applied only when plumbing is not working properly)
Step 2 — Age-Related Leak & Water Waste Risk
Older pipes are significantly more prone to pinhole leaks, corrosion, and water waste. After year 15, we apply a 2.5% waste increase per year up to a 35% maximum — applied to your monthly water bill, scaled by home size, bathroom count, and foundation type, then multiplied by 12.
Waste Rate = (Age − 15) × 2.5% — capped at 35%
Annual Water Waste = Monthly Bill × Waste Rate × sizeMult × bathroomMult × foundationMult × 12
Step 3 — Cost of Plumbing Issues
Each significant plumbing issue (leak, burst pipe, major clog, water heater failure) averages $350 per event — a conservative average for emergency plumbing service calls. Adjusted upward based on inspection history and scaled by foundation type, since slab access significantly increases remediation cost.
Issue Cost = Issues × $350 × maintFactor × foundationMult
Step 4 — Performance Signal Surcharge
Each behavioral warning you flagged indicates active or developing plumbing problems. Each signal adds a weighted annual surcharge to your total estimate.
Signal Cost = (sig1 ? $180 : 0) + (sig2 ? $200 : 0) + (sig3 ? $400 : 0) per year
Step 5 — Estimated Annual Savings
Updated or repiped plumbing typically reduces water waste and eliminates recurring emergency call costs. We estimate a conservative 20% reduction in your annual water bill plus elimination of ongoing issue costs.
Annual Savings = (Monthly Bill × 20% × 12) + (Issues × $350)
Step 6 — The Repipe Threshold ($15,000)
A professional rule of thumb used in the plumbing industry: multiply your pipe age by any repair quote. If the result exceeds $15,000, a full repipe is almost always the more financially sound decision — especially on a slab foundation where access costs compound quickly.
Repipe Threshold = Pipe Age × Repair Quote
Example: 30 years × $600 quote = $18,000 → Exceeds $15,000 → Consider Full Repipe
