A leaking water heater in Lorton should be dealt with promptly, because the water keeps escaping until the supply to the tank is closed. Start with the safe steps below: close the cold-water valve on top of the heater if you can reach it without stepping through water, keep people and pets away from the wet floor, and move anything stored nearby.
Then call. We answer 24/7, ask a few quick questions about where the water is coming from, and connect you with an independent local plumbing professional. Pricing is explained on the phone before any work begins, with no hidden fees.
The rest of this page explains what the leak might be and what happens next. You do not need to read it to get help. If the heater has also stopped making hot water, see our page on no hot water for how the two problems connect.
What to do right now: safe steps only
Keep it simple. Close the cold-water valve on the supply pipe above the heater, only if you can reach it dry and safely. If water is pooling near outlets, appliances or a panel, stay out of the area and do not touch any electrical controls.
Put towels down, move boxes and stored items away from the heater and note the model label and age if you can read them from a safe spot. Do not open the relief valve, do not relight a pilot and do not try to tighten fittings yourself. Those steps are for the pro.
Where the leak is coming from: fittings, valve, drain valve or the tank
Not every wet floor means a dead heater. The pro looks at the top first: the cold and hot connections, the temperature and pressure relief valve and its discharge pipe. A loose or worn fitting is a repair, and a dripping relief valve points toward pressure or temperature trouble that needs a closer look.
Next is the drain valve near the bottom, which can weep without the tank itself being compromised. Finally, the pro checks the tank. Water coming from the bottom or the jacket of the tank, rather than a fitting, is a bad sign, because it usually means the inner tank has failed.
If your leak is from the relief valve, the page on a gas water heater and the one on an electric water heater both explain how the two fuel types differ in what could be driving it.
Callers describe this in different ways: a relief valve leaking onto the floor, water around water heater fittings after a hot shower, or a slow drip at the base. Each description points the technician toward a different place to look first.
Leaks that can be repaired and a tank that has failed
A fitting, a valve or a connection can usually be repaired or replaced. If the leak is there, the heater may have plenty of life left, and the pro will say so. Water heater leaking from bottom of the tank is different. Once the steel inner tank has rusted through, a repair is rarely practical, and the unit needs to be replaced.
The pro explains which situation you have and shows you the evidence where it is visible. You then decide with the facts in front of you. If the leaking water heater in Lorton is only a few weeks old, mention it, because it helps the pro work out what happened.

Protecting floors, closets and ceilings below
Water spreads further than it looks. A heater in a basement can send water under finished walls and into stored boxes, and a heater in a second-floor closet or an upstairs townhome can send water through the ceiling below. Move belongings out of the wet area.
If water is dripping through a ceiling, keep people clear of it. Call us first about the heater and let the pro advise on next steps. For damage to the building itself, a restoration company is the right contact, and photographs of the leak and the wet areas are worth taking before you clean up.
Replacement after a tank leak
When the tank has failed, the next step is replacement. The pro confirms fuel type, size and location with you, then plans the swap. Our page on water heater installation explains what the work involves, from sizing to the day itself.
It is a good moment to ask about a drain pan, an expansion tank and whether the relief valve discharge pipe is routed properly. The pro can do all of it while the old heater is out.
If you want same-day service, say so on the phone. Same-day dispatch is offered where available, and the pro explains pricing before any work starts.
Leaking water heaters in Lorton homes, plus drain pans and leak alarms
Where the heater sits changes the damage. Single-family homes often keep the heater in the basement or an attached garage, where a leak may reach a floor drain or a hard floor, but nobody should assume it will be contained. Townhomes and condos near Lorton Station often have the heater in a closet with finished rooms right next to it. Our pages on water heater help in Williamsburg Square and water heater help in Southgate Woods cover the 1970s homes and early-1970s townhouses there.
A drain pan piped to a safe spot gives a slow leak somewhere to go, and a small battery leak alarm on the floor can warn you before a drip becomes a flood. Neither stops a leak, but both buy time and reduce the damage. Ask the pro whether either suits your closet or basement.

Questions about a leaking water heater in Lorton
It can be. Hot water can scald, wet floors cause falls, and water near electrical equipment is a hazard. Stay away from the wet area, keep children and pets back and call. If you smell gas, leave the home and call the gas utility and 911 from outside.
If the leak is from a fitting, valve or connection, often yes. If the steel tank itself has failed, a repair is rarely practical and replacement is the usual path. The pro identifies the source and tells you plainly which applies.
The relief valve opens to protect the tank from too much pressure or heat. A steady drip can mean a worn valve or a pressure or temperature problem. Do not open or plug the valve yourself; call a pro to inspect it.
If you can reach the cold-water valve on top of the heater safely, closing it slows or stops the flow of new water into the tank. If the area is wet or you cannot get to the valve without stepping through water, skip it and call.
Condensation tends to be light, show up on cold pipes or on a tank in a humid room and dry up when conditions change. A real leak keeps returning, grows over time and leaves a puddle or rust trail. If you are not sure, take a photo and describe it when you call.
As soon as is practical. A failed tank does not repair itself, and the amount of water it releases can increase without warning. Call early so the pro can plan, and use the safe steps above to limit damage in the meantime.
It is a sticker on the side of the tank, usually near the middle or the top. If the floor is wet or you cannot reach it safely, skip it, and the pro can read it on arrival.
It is better not to. Using the heater keeps the tank filling and may make the leak worse. Close the cold-water valve if you can do so safely and wait for the pro.
