FAQs
How can I tell if my main water line is leaking?
Common warning signs include a sudden drop in water pressure throughout the house, unusually high water bills, standing water or soggy spots in the yard, unexplained foundation cracks, discolored tap water, or the sound of running water when no fixtures are on. If you notice any of these, shut off your main valve and call a licensed plumber right away to prevent further damage.
What are the most frequent causes of main water line issues in Fountain City?
Fountain City’s clay soils and seasonal freeze-thaw cycles put steady stress on underground pipes, leading to cracks and joint separation. Other culprits include tree-root intrusion, pipe corrosion in older galvanized or cast-iron lines, ground shifting from heavy rains, and damage from nearby construction. Knowing the local soil and climate risks helps us tailor repairs that last.
Will my yard have to be excavated to repair or replace the main line?
Not always. We start with video camera inspection to pinpoint the problem. For isolated leaks or root intrusions, we can often perform spot repairs with minimal digging. If the pipe is severely deteriorated, trenchless technologies such as pipe bursting or cured-in-place lining allow us to replace up to 100 ft of pipe through two small access pits, preserving most landscaping, driveways, and sidewalks.
How long does a main water line repair or full replacement take?
A simple spot repair can usually be completed in 4–6 hours. Trenchless replacement of an entire service line (from the meter to the house) typically takes one day, including inspection, installation, and pressure testing. Traditional open-trench replacements may span two to three days, depending on pipe length, depth, and restoration work.
Do I need a permit for main line work in Fountain City, and who handles it?
Yes. The City of Knoxville (which governs Fountain City) requires a plumbing permit and often an inspection of any main service line repair or replacement. Our team pulls all necessary permits, schedules city inspections, and ensures the work complies with the 2021 International Plumbing Code and local amendments, so you don’t have to navigate the paperwork yourself.
What does main water line repair cost, and do you offer financing?
Costs range widely—from $350–$750 for a minor clamp repair to $2,500–$4,500 for trenchless replacement of a typical ¾-inch, 60-ft line. Factors include pipe material, depth, access, and restoration requirements. We provide a detailed, no-obligation estimate after our camera inspection. To ease the expense, we offer zero-interest financing for 12 months and longer-term plans up to 60 months through GreenSky and TVA’s EnergyRight program.
