FAQs
What qualifies as a main line plumbing emergency?
Any sudden issue that stops the flow of clean water into your home or prevents wastewater from leaving it through the sewer line is considered an emergency. Examples include a completely clogged or collapsed sewer main, a burst or leaking water main, sewage backing up through floor drains or toilets, or severe water pressure loss linked to the main service line. These problems can cause property damage, health hazards, and service interruptions, so they require immediate professional attention.
How quickly can your Karns emergency plumbers arrive?
We offer 24/7 dispatch for Karns and the surrounding Knoxville area. In most cases, a licensed technician can be at your door within 60–90 minutes of your call, day or night, including weekends and holidays. Our trucks are fully stocked with pipe cutters, hydro-jetting equipment, sewer cameras, and common repair fittings so we can start diagnosing and fixing the problem as soon as we arrive.
What are common signs that my main sewer line is blocked or failing?
Warning signs include multiple fixtures draining slowly at the same time, gurgling sounds in drains or toilets, foul odors in bathrooms or basements, water or sewage bubbling up around floor drains, wet or sunken spots in the yard, and frequent need for plumber-grade augering. If you notice any combination of these symptoms, shut off water usage and call our emergency line right away to avoid a full backup.
Can you repair or replace main water or sewer lines without digging up my yard?
Often, yes. We use trenchless technologies such as pipe bursting and cured-in-place pipe (CIPP) lining. These methods allow us to rehabilitate or replace damaged pipes through small access points, preserving landscaping, driveways, and sidewalks. After a camera inspection, we’ll recommend trenchless or conventional excavation based on pipe depth, material, and extent of damage, and provide a clear estimate for each option.
How much does emergency main line service cost, and do you offer upfront pricing?
Because every situation is unique, costs vary with pipe depth, material, length, and whether trenchless methods or excavation are required. That said, we charge a modest emergency dispatch fee, then perform an on-site diagnostic and present a flat, upfront price before any work begins. There are no hidden charges or weekend/holiday surcharges once you approve the quote. We also offer financing and accept most homeowner insurance claims for qualifying water or sewer line failures.
What should I do while waiting for the emergency plumber to arrive?
1) Turn off your home’s main water shut-off valve if water is leaking. 2) Avoid using toilets, sinks, or appliances that drain into the sewer if you suspect a blockage. 3) Keep children and pets away from any standing water or sewage. 4) If water is near electrical outlets, switch off power to the affected area at the breaker panel. 5) Gather any relevant information—past plumbing invoices, home warranty paperwork, or photos of the problem—to speed up the assessment when the technician arrives.
