Question 1

Do you know where the main water shut-off is?

Accepted Answer

If you have a leak, find the main shut-off before the plumber arrives. It's usually in the basement, utility room, or near the water meter. Knowing this prevents extra damage while you wait.

Question 2

What kind of pipes do you have?

Accepted Answer

Copper, PEX, or PVC — knowing your pipe material helps the plumber bring the right fittings on the first visit.

Question 3

Is the water still on, and is the leak active?

Accepted Answer

Active leaks are emergencies — most plumbers offer 24/7 callouts but charge extra. If you can shut off water and wait, day-rate work is much cheaper.

Question 4

Have you taken photos of the leak or fixture?

Accepted Answer

A photo of the problem area + the affected fixture helps the plumber bring the right replacement parts.

Question 5

Is anyone home with a respiratory issue?

Accepted Answer

Some chemical drain treatments produce strong fumes. Mention any health concerns in advance so the pro can choose alternative methods.

Question 8

What is a Drain snake (auger)?

Accepted Answer

A flexible coiled wire tool inserted into drains to break up or pull out clogs. Manual snakes work for minor blockages; powered drain machines handle tougher clogs in main sewer lines. A step up from a plunger but less aggressive than hydro-jetting.

Question 9

What is a Hydro-jetting?

Accepted Answer

A drain-cleaning method that uses high-pressure water (up to 4,000+ PSI) to scour pipe interiors and clear stubborn blockages, grease, and tree roots. More thorough than snaking but requires professional equipment and should only be done by trained technicians.

Question 10

What is a Cleanout (plumbing)?

Accepted Answer

A capped fitting installed in a drain or sewer line that provides access for cleaning and inspection. Cleanouts are typically Y-shaped or T-shaped pipe fittings with a removable threaded plug. Building codes require them at specific intervals and changes of direction in the drainage system — typically every 100 feet in a straight run and at every major bend. A plumber can insert a drain snake or hydro-jetting nozzle through the cleanout to clear blockages without cutting into walls or digging up floors. Knowing where your cleanouts are located (commonly at the foundation wall where the main drain exits the house, and at the property line where the sewer lateral begins) saves significant time and money during a drain emergency. If your home lacks accessible cleanouts — common in houses built before the 1960s — a plumber can install them for $200–$500 each.

Question 11

What is a Sewer camera inspection?

Accepted Answer

A diagnostic procedure where a waterproof, self-leveling video camera attached to a flexible rod is fed through the sewer line to visually inspect pipe condition, identify blockages, locate root intrusion, find cracks or offsets, and determine exact pipe material and depth. The camera transmits real-time video to a monitor and records the footage; a built-in sonde (radio transmitter) allows the technician to precisely mark problem locations above ground. Standard inspection for a residential main line (75–150 ft from house to city connection): $125–$400. A lateral-launch camera that can inspect branch lines adds $100–$200. You should request a sewer camera inspection before buying a home (not included in standard home inspections), after repeated drain backups, before major landscaping near sewer lines, or to verify a contractor's repair claims. The footage reveals problems invisible to drain snakes: bellied (sagging) pipes that collect debris, orangeburg (bituminous fiber) pipe deterioration, cast-iron pipe tuberculation, and offset joints from ground shifting. Many plumbers offer the inspection free or discounted ($50–$100) if you hire them for the resulting repair.
