How do I know if I have a hidden water leak?

Signs of a hidden leak include an unexplained increase in your water bill, the sound of running water when everything is off, soft spots or staining in walls or ceilings, and mold or mildew in areas that shouldn't be damp. You can confirm a leak by turning off all water fixtures and watching your water meter if it's still moving, water is escaping somewhere. Call us for a leak detection inspection.

My toilet keeps running is that a big deal?

A running toilet wastes 200–700 gallons of water per day, adding significantly to your water bill. The most common cause is a worn flapper that no longer seals properly, or a faulty fill valve that doesn't shut off at the right water level. Both are inexpensive repairs. If your toilet has been running for a while, your water bill likely reflects it.

What causes low water pressure in my home?

Low water pressure throughout the house usually means a problem at the main supply a partially closed main shutoff, a failing pressure-reducing valve, or supply line scaling in older galvanized pipes. Low pressure at a single fixture typically means a clogged aerator or cartridge. We diagnose the cause and recommend the right fix.

How long do residential water pipes last?

Copper pipes typically last 50+ years. Galvanized steel (common in older Duluth and Superior homes) lasts 20–50 years before corrosion causes flow restriction and leaks. PVC and PEX are relatively recent materials that should last 50+ years. If you're seeing rust-colored water, frequent joint leaks, or low flow in an older home, the galvanized supply system may be nearing the end of its useful life.

Do I need a permit for plumbing work?

Most significant plumbing work, such as water heater replacement, new fixture installation involving supply or drain modifications, sewer line repair, and pipe replacement, requires a permit in Duluth and Superior. We pull permits when required and schedule inspections. Permitted work is documented, code-compliant, and protects your home's value. We don't skip permits to save time.

Your Safety Is Our Priority

Plumbing Safety — Water Damage, Backflow & Pipe Integrity

Plumbing failures cause more water damage than any other home system. Improper repairs create backflow contamination risk and hidden leaks that damage structure over time. Advantage Air follows proper safety and code requirements on every job.

Shut-Off Valve Assessment

Every homeowner should know where their main water shutoff is and be able to operate it. We check your main shutoff and individual fixture shutoffs during service visits — a stuck-closed valve during an emergency can turn a minor leak into a major flood. We replace corroded or stuck valves when found.

Backflow Prevention

Backflow occurs when contaminated water is drawn back into your drinking water supply through cross-connections. We inspect backflow prevention devices, install backflow preventers where required, and test existing assemblies to ensure your water supply is protected from contamination.

Water Pressure Testing

Water pressure above 80 PSI stresses pipe joints, fixture valves, and water heater connections and is a common hidden cause of leaks and premature fixture failure. We measure supply pressure and install or adjust pressure-reducing valves to keep your system in the safe operating range.

Leak Detection

Hidden leaks inside walls, under slabs, or in crawl spaces waste water and cause serious structural damage. We use pressure testing and inspection equipment to locate leaks that can’t be seen, and repair them with minimal disruption to your home.

Drain Camera Inspection

Camera inspection lets us see exactly what’s inside your drain pipes without unnecessary digging or demolition. We use camera inspection to diagnose recurring clogs, check pipe condition before a home purchase, and verify line repairs are complete before closing up walls or floors.

Code-Compliant Work

All plumbing work we perform is done to current code and permit requirements. We pull permits when required, use listed materials, and document our work. Code-compliant plumbing protects your home’s value and your family’s safety.
