Rust-colored Water
Rust-colored Water | Tank Water Heater | Plumbing | Lynchburg
Imagine turning on the tap and being greeted by that unmistakable rusty tint—usually the first warning that your tank water heater is fighting corrosion on the inside. Minerals in Lynchburg’s water can eat away at the unit’s lining, loosening iron particles that discolor every shower, load of laundry, or glass you pour. Left unchecked, that ugly color can quickly become leaks, foul odors, or a completely failed system.
HEP’s local plumbing team makes rust-colored water worries disappear. We’ll inspect and flush the tank, replace depleted anode rods, and recommend repair or replacement only when it truly benefits you. With same-day service, transparent pricing, and a satisfaction guarantee, we restore clear, clean water—and your peace of mind—before the next load of whites hits the washer.
FAQs
What causes rust-colored water to come from my tank-style water heater?
The most common source is internal corrosion. Over time the sacrificial anode rod inside the tank is consumed, allowing oxygen in the water to attack the steel liner and create iron oxide (rust). Sediment that collects on the bottom of the tank can also trap iron and give the water a reddish-brown tint when it is stirred up by heating cycles. In Lynchburg, our moderately hard municipal and well water accelerates sediment build-up, so heaters that are not flushed regularly tend to show discoloration sooner. Galvanized steel supply lines, aging copper-to-steel connections, or a failing water-main in the neighborhood can add additional iron to the water, but if the color appears only in the hot side 90 % of the time the heater is to blame.
Is rust-colored hot water dangerous for my family’s health?
Iron oxide itself is not considered toxic and the U.S. Environmental Protection Agency classifies it as a “secondary contaminant,” meaning it mainly affects taste, color, and odor. That said, discolored water can stain laundry and fixtures, clog faucet aerators, and in severe cases harbor bacteria that thrive in sediment layers. If anyone in the home has a compromised immune system, or if you notice a metallic taste or sulfur-like odor along with the color, you should avoid drinking the water until a plumber can inspect the system and perform a bacterial test. Even when health isn’t at risk, discolored water is a sign the tank is deteriorating and could eventually leak, so it should be addressed promptly.
How can I tell whether the rust is coming from my water heater or from Lynchburg’s city water supply?
Run only the cold tap at several fixtures (especially an outdoor frost-free hose bib that bypasses the water heater). If the cold water is clear but the hot water is rusty, the problem is almost certainly inside the heater. If both are rusty, ask a neighbor whether they see the same color; if they do, call Lynchburg Water Resources at 434-455-4250 to report the issue. Another quick test is to fill a clear glass with hot water, let it sit for a minute, and look for tiny orange particles settling to the bottom—those flakes usually point to a corroding tank or anode rod.
Can flushing the tank solve rust-colored water issues, and how often should it be done?
Yes, a full drain-and-flush removes iron-rich sediment before it can discolor your water. The process involves shutting off power or gas, closing the cold inlet, attaching a hose to the drain valve, and running water until it clears. We also open the T&P valve briefly to break any vacuum and stir up debris. Most manufacturers recommend flushing at least once a year; in Lynchburg’s mineral-rich water we often suggest every 6 months if you notice any coloration or rumbling noises. If you have not flushed the tank for several years and the water is already rusty, the sediment may be so thick that flushing alone will not solve the problem—an anode rod replacement or a new heater might be required.
When should I replace the anode rod or the entire water heater?
Inspect the anode rod every 2–3 years; if more than 6 inches of the core wire is exposed or the rod is coated with calcium, replace it. A new rod usually costs less than $100 installed and can add 3–5 years of life to the tank. Replace the entire heater if: (1) it is 10–12 years old, (2) you see water pooling around the base, (3) you hear loud popping or crackling even after a flush, or (4) rust returns within days of service. Modern high-efficiency or hybrid heat-pump models can cut your energy bills by 30 % or more, so upgrading may pay for itself over time.
How quickly can a Lynchburg plumber address rust-colored water, and what will the service include?
At our plumbing company we offer same-day appointments in most Lynchburg neighborhoods, Forest, Madison Heights, and the surrounding area. A standard rust-diagnosis visit includes: (1) visual inspection of the tank, piping, and shut-off valves; (2) sediment flush; (3) anode-rod check and replacement if needed; (4) hardness and iron testing of incoming water; and (5) written recommendations on repair vs. replacement. The service typically takes 60–90 minutes and costs $125–$225, credited toward any larger repair done the same day. Emergency calls are available 24/7 for a modest after-hours fee if the tank is leaking or water quality suddenly worsens.
