What to Actually Ask a Plumber Before Agreeing to a Repiping Job

A contractor says your whole house needs to be repiped. Before you agree to anything, you deserve straight answers and a clear picture of what the job actually involves. At Trident Plumbing & Drain, we have seen too many homeowners sign off on work they did not fully understand. These are the questions worth asking any plumber in Surprise, AZ before the work begins.

“How Do You Know the Whole System Needs Replacing?”

This should be your first question. A reputable plumbing company will not recommend whole-home repiping based on a single leak. They should point to specific findings: discolored water, pinhole leaks in multiple spots, visible corrosion, or pipe material that has simply run its course. According to the American Society of Home Inspectors, galvanized steel pipes last 20 to 50 years and copper can last 50 or more. If problems are isolated, partial repairs may be all you need.

“What Pipe Material Will You Use, and Why?”

The right material depends on your home, your water, and your budget. The most common options are:

• PEX: Flexible, freeze-resistant, and cost-effective. Common across the Southwest.
• Copper: Long-lasting but labor-intensive and sensitive to acidic water.
• CPVC: A solid rigid plastic option for both hot and cold lines.

Any contractor offering honest plumbing services will explain the tradeoffs without steering you toward the priciest choice.

“What Exactly Is Included in the Scope of Work?”

Get it in writing. Does the job cover supply lines only, or drain lines too? Who patches the drywall afterward? Is the water heater connection included? These details affect your total cost and timeline. A contractor standing behind their plumbing repairs will not hesitate to spell all of this out before work starts.

“Are You Licensed, Bonded, and Insured in Arizona?”

Non-negotiable. The Arizona Registrar of Contractors requires a valid license for all residential plumbing work. You can verify any contractor’s license at roc.az.gov. A trustworthy plumbing company will hand you their number and tell you to check it.

“What Warranty Comes With the Work?”

Ask about labor and materials separately. The labor warranty is what protects you if a fitting fails after the crew leaves. Get the terms in writing, including how long it lasts and how to file a claim.

What Our Clients Ask US

How will I know the work was done right?

A permitted job requires a city or county inspector to sign off before completion. You can also request a pressure test on the new lines before walls are sealed.

Do I need to do anything to prepare my home before the crew arrives?

Clear access to areas like cabinets under sinks, utility closets, and the water heater. If the crew needs to move through specific rooms, having a path ready saves time and keeps the job on schedule.

Will the new pipes affect my water pressure or water quality?

In many cases, yes, for the better. Old galvanized pipes are notorious for buildup that restricts flow and affects taste. Homeowners with aging galvanized systems often notice an immediate difference after repiping with copper or PEX.

How do I know the permit was actually pulled before work started?

Ask for the permit number before day one. In Arizona, permits are public record and can be verified through your city or county building department. A contractor who pulled the permit will have no problem showing you.

What should I do if I notice a problem after the job is complete?

Contact the contractor in writing and reference your warranty terms. Document the issue with photos before anything is touched. If the contractor is unresponsive, the Arizona Registrar of Contractors handles complaints against licensed contractors.
