FAQs
What are the most common causes of low water pressure in Knoxville homes?
In Knoxville, the leading culprits are aging galvanized-steel or polybutylene supply lines that have corroded or scaled shut, undersized branch lines in older houses, partially closed main shut-off valves, mineral buildup from our moderately hard municipal water, and pressure-reducing valves (PRVs) that are out of adjustment. While fixtures can clog, the root problem is often pipe diameter and internal corrosion, which is why upgrading pipe material and sizing is the long-term fix.
How can a pipe upgrade restore or improve my water pressure?
Replacing old ½" galvanized or polybutylene lines with modern ¾" or 1" PEX or Type L copper instantly increases internal diameter and eliminates corrosion, allowing a higher volume of water to reach each fixture. Unlike booster pumps that only add pressure, a repipe removes flow restrictions, balances pressure on all floors, and complies with current plumbing code, preventing future drops caused by continued rust or scale buildup.
Which pipe materials work best for Knoxville’s climate and water quality?
For most residences we recommend PEX-A or PEX-B because it resists mineral buildup, handles our winter freeze/thaw cycles well, and is cost-effective to install with minimal wall demolition. Type L copper is excellent for exposed runs or high-temperature applications but carries a higher material cost. CPVC is acceptable but more brittle in cold weather. We’ll review your home’s layout, budget, and any HOA requirements before choosing a material.
Do I need a permit or inspection for a whole-home repipe in Knoxville?
Yes. The City of Knoxville and Knox County Codes Enforcement require a plumbing permit for any project that involves replacing or relocating supply lines. Our licensed plumbers pull the permit for you, schedule the rough-in and final inspections, and ensure all work meets the 2021 International Residential Code (IRC) and local amendments. Skipping the permit can lead to fines and problems during resale or insurance claims.
How long will I be without water during the upgrade, and can I stay in the house?
A typical 2-bathroom, 1,800 sq ft home takes 1-2 days for rough-in and another half-day for drywall patching. We stage the job so that water is turned off only during the pipe switch-over—usually 4-6 hours. If you have multiple bathrooms, we can repipe zone-by-zone to keep at least one restroom operational. Most clients remain in the home throughout the process with minimal disruption.
What does a pipe upgrade cost in Knoxville, and is it worth the investment?
Costs vary by size, material, and accessibility, but full repipes in the Knoxville area generally run $4–$7 per heated square foot. A 2-bath home might cost $6,000–$9,000 with PEX and $9,000–$12,000 with copper. Besides restoring strong, even pressure, a new plumbing system increases property value, lowers the risk of leaks that can cause costly water damage, and may earn insurance discounts—making it a worthwhile long-term investment.
