What plumbing should new homeowners check first?

New homeowners should first locate the main water shut-off valve, inspect the water heater, look under sinks, check toilets, and watch for hidden leak signs.

Why is the main water shut-off valve important?

Knowing where the main water shut-off valve is can help reduce water damage during leaks, burst pipes, or plumbing emergencies.

Should new Florida homeowners check pipe materials?

Yes. Older Florida homes may have cast iron or polybutylene plumbing, which can affect inspections, insurance, maintenance, and repair planning.

Do new homeowners need to check backflow testing?

If the property has irrigation, commercial-style plumbing, HOA systems, or a required backflow preventer, homeowners should ask when the device was last tested.

When should a new homeowner call a plumber?

Call a plumber if there are leaks, corrosion, sewer odors, slow drains, high water bills, water heater concerns, unknown pipe materials, or damaged shut-off valves.

4. Identify the Pipe Material in the Home

Florida homes may have different plumbing materials depending on the year built. Some materials may be more likely to create insurance, inspection, or repair concerns.

Cast Iron Pipes

Common in many older Florida homes and may deteriorate over time.

Polybutylene Pipes

Known to create concerns in some older homes and insurance situations.

Copper, PVC, CPVC, or PEX

Condition, age, installation quality, and location still matter.
