Leaking Water Heater Repair in Newark, DE

What to do right now (before we arrive)

These steps can save your floors while you wait:

1. Shut off the cold water supply. Look for the valve on the cold pipe at the top of the heater. Turn the handle clockwise, or turn a lever handle so it sits across the pipe.
2. Turn off the energy source. Electric heater: switch off its breaker in the panel. Gas heater: turn the gas control knob to "Off" or "Pilot."
3. Protect your stuff. Move boxes, rugs and anything that can soak up water.
4. Don't touch the relief valve if it is spraying hot water. It may be releasing dangerous pressure.
5. Call us at (302) 732-0874.

If you smell gas, leave the house and call your gas utility or 911 from outside first.

Where water heater leaks come from

Our leaking water heater repair process

1. Stop the waterIf you haven't already, we shut off water and fuel and drain the tank if needed to stop the flow.
2. Trace the sourceWe dry the area and watch fittings, valves and seams to find exactly where water starts, not just where it lands.
3. Find the root causeA dripping relief valve often means high water pressure or a missing expansion tank. We test pressure so the leak doesn't come back.
4. Repair or replaceWe fix valves and fittings on the spot when parts are on hand. If the tank has failed, we price a replacement before any work.

Common leak causes we see in Newark homes

Thermal expansion. When water heats up, it expands. Many homes have a check valve or pressure regulator at the meter that keeps that extra volume from flowing back to the street. Without an expansion tank, pressure spikes every time the heater runs. Over time that stresses the relief valve, fittings and tank.

Sediment and corrosion. Newark's water is only slightly hard, but minerals still settle at the bottom of a tank. Sediment traps heat against the steel and speeds up rust. A worn-out anode rod lets the tank itself start to corrode.

Age. Many homes around Newark were built in the 1970s and 1980s, and plenty still have heaters well past 12 years old. Old tanks are far more likely to leak.

Cost factors for leak repairs

What you pay depends on where the leak is and what failed:

• Fitting or connector leaks are usually the lowest cost fix.
• Relief valve or drain valve replacement costs more because the tank must be partly drained.
• Adding an expansion tank adds parts and labor but protects the whole system.
• A failed tank means replacement. See our water heater replacement page.
• After-hours visits may cost more than daytime visits. We tell you before we come.

DIY vs. calling a pro

Tightening a loose supply connection is something some homeowners can do once the water is off. But most leaks involve hot water, pressure and either gas or 240-volt power. Swapping a relief valve the wrong way, or capping a dripping relief line, can create a real explosion risk. If you are not sure where the water is coming from, shut the heater down and call.

Delaware insurance and licensing notes for leaks

What insurance tends to cover. The Delaware Department of Insurance's homeowners guide says a broad (HO-2) policy covers problems from accidents with plumbing, heating and appliances. In practice, most policies help with sudden water damage to floors and walls but not the cost of the failed heater. Slow, long-term seepage is often excluded. The same guide notes flood insurance is never part of a standard homeowners policy, so groundwater in a basement is a separate matter.

What to do before you file. Take photos and video of the tank, the leak point and every wet area before cleanup. Keep the damaged parts if you can. Call your agent or insurer to ask about deadlines, and read our guide to whether homeowners insurance covers a water heater leak. For general questions, the Department's consumer line is 302-674-7300.

Who can fix it. Delaware's plumbing board must license anyone doing plumbing work in the state. If the repair turns into a replacement, a permit and inspection follow.

Local note: Leaks do the most damage where a heater sits above finished space. That is common in Bear townhome utility closets and Pike Creek condos and townhouses, where water can reach a neighbor's ceiling. In Wilmington, many tanks sit in old stone or block basements where a slow drip goes unseen for weeks.

A hidden leak can also show up first on the water bill. See why a water bill jumps when a water heater leaks.
