FAQs
Why is my water pressure low and how can pipe upgrades help?
In most Erwin homes, persistent low pressure is caused by internal pipe corrosion, mineral buildup, or undersized supply lines installed decades ago. As pipes narrow, friction loss increases and pressure at fixtures drops. Upgrading to modern, properly-sized copper or PEX lines instantly restores the full municipal pressure (usually 55–70 psi in Erwin) because the interior diameter is larger and the walls are smoother, allowing water to flow with less resistance.
What types of pipe materials are recommended when upgrading for better water pressure in Erwin homes?
For pressure-boosting projects we typically suggest Type L copper, PEX-A, or PEX-B. Copper is durable, code-accepted everywhere, and handles high temperature and pressure well, but it costs more. PEX-A/B is flexible, installs quickly with fewer fittings (reducing friction loss), and resists freeze damage—ideal for Erwin’s mixed winter temperatures. PVC or CPVC is usually reserved for irrigation or hot-water runs, not whole-home pressure upgrades.
How do I know if I need a complete house re-pipe or just a targeted pipe replacement?
A licensed plumber will perform a pressure and flow test at several fixtures, inspect exposed piping, and may use a camera or ultrasonic thickness gauge. If low pressure is widespread and pipes are galvanized or over 40 years old, a full re-pipe is more cost-effective than chasing leaks section by section. If only one branch line is clogged or undersized—often a back bathroom or second floor—targeted replacement may solve the problem at a fraction of the cost.
Will upgrading my pipes increase water flow without violating Erwin’s plumbing codes?
Yes. The Erwin Building & Codes office follows the 2018 IRC and IPC, which set minimum and maximum pipe sizes, velocity limits, and 80 psi maximum static pressure. By replacing ½-inch galvanized with ¾-inch copper or PEX mains and keeping fixture branches at code-approved sizes, we meet all requirements. We also pull the necessary permits and schedule the final inspection to certify compliance.
How long does a typical water pressure pipe upgrade project take and will my water be shut off?
A whole-home re-pipe in an average 2-bath, 1,800 sq ft Erwin house takes two to three days. Water is usually off only during work hours and restored each evening; total outage time is 4–6 hours. Targeted upgrades (one or two lines) can be completed in half a day with minimal interruption. We protect floors, open only the walls we need, and haul away debris immediately.
What is the cost range and are there financing options or rebates available in Erwin?
Targeted pipe replacements start around $700–$1,200, while a complete copper re-pipe can run $5,000–$9,000 depending on square footage and number of fixtures. PEX typically lowers the total by 20–30 percent. We offer 0% interest financing for up to 12 months, and Tennessee Valley Authority’s eScore program occasionally provides rebates when pressure upgrades are combined with water-saving fixtures.
