Buying a home in Naples, Bonita Springs, Marco Island, or anywhere in Southwest Florida is a significant investment, and one that often involves plumbing infrastructure that a standard home inspection will not fully evaluate.
At A-1 Plumbing & Gas, pre-purchase plumbing inspections are one of the most valuable services we provide. The findings regularly save buyers thousands in unexpected repair costs and occasionally change the direction of a purchase negotiation entirely. Here is what a dedicated plumbing inspection covers that a general home inspection typically misses.
A licensed general home inspector runs faucets, flushes toilets, and checks for visible leaks and water pressure. They are trained to identify obvious problems, but they are not equipped to evaluate what is inside the pipes.
A general inspection will not catch:
- Active slab leaks not yet causing visible damage - Polybutylene piping throughout the home (a known failure risk) - Root intrusion in the sewer line - Sediment and scale buildup in galvanized lines that have reduced interior diameter - Failed expansion tanks or failing pressure regulators - A water heater near the end of its service life
In Florida, these are not rare findings, they are common in homes more than 15 to 20 years old.
A dedicated plumbing inspection from a licensed plumber includes:
**Pipe material identification.** Knowing whether your potential new home has copper, PEX, CPVC, polybutylene, or galvanized lines tells you a great deal about the system's age, expected lifespan, and any near-term replacement risk. Polybutylene in particular, used widely in homes built between roughly 1978 and 1995, is known to fail and should trigger serious negotiation.
**Drain camera inspection.** Running a camera through the main sewer line shows root intrusion, pipe bellies (low spots where debris collects), cracked or collapsed sections, and any existing blockages. This is the single most valuable piece of a pre-purchase plumbing inspection. A failing sewer line is a five-figure repair.
**Water heater evaluation.** Age, condition, sediment level, expansion tank presence, and compliance with current code. Florida requires expansion tanks in homes with backflow preventers, and many older installs lack them.
**Fixture and shutoff valve check.** Shutoff valves under every sink and at every toilet should operate smoothly. Corroded or stuck valves are a silent problem, they work until you need them in an emergency and then they do not.
**Slab leak screening.** Pressure testing or thermal imaging to detect active leaks beneath the slab before purchase.
A pre-purchase plumbing inspection typically costs a few hundred dollars. A sewer line replacement costs several thousand to tens of thousands of dollars. A whole-home repipe for a home with failing polybutylene can run well into five figures for larger homes.
Knowing the condition of the plumbing before you close allows you to negotiate repairs, request a price reduction, or walk away from a property with serious undisclosed problems.
