What should you do first if a water heater is leaking in a Wichita home?
If the heater is electric, switch its breaker off at the panel. If it is gas, turn the gas control to the off position. Then shut the cold-water inlet valve on top of the tank, and call. Keep clear of any gas smell and of water near electrical equipment.
Most water heaters have a cold-water inlet valve on top, and a valve on the supply line nearby. Closing the inlet stops fresh water going into the tank and out through the leak. If you cannot reach the valve safely, shut the main supply instead, which is usually in the basement or the utility room.
A gas heater needs particular care. If you smell gas, leave the building, and call the gas utility from outside. Do not light a flame or switch an electrical device on or off in a room where you smell gas. Once it is safe, the crew can look at the heater and the floor beneath it.
- Switch off the power or the gas supply to the heater
- Close the cold-water inlet valve on top of the tank
- Keep clear of water near outlets, cords and the electrical panel
- Move stored boxes and items off the wet floor
Does a water heater leak in Wichita always mean the heater has to be replaced?
Not always. A leak from a fitting, a valve or a connection can often be repaired by a plumber, but a leak from the tank or its seams usually means the unit has failed. The plumber decides which, and the crew notes the cause in the drying log.
Ask the plumber to show you where the water came from before you decide. A drip from the relief valve may be a valve that needs replacing or a pressure problem that needs a closer look. A puddle that comes from the base of the tank almost always means the tank has to be replaced.
The drying work does not depend on the answer. The floor under the heater is dried either way, because water that has been under the tank cannot be seen and must be read.
Why does water from a heater spread so far across a floor?
Water runs down the outside of the tank and across the floor toward the lowest point, and it passes under any flooring or wall base it meets. A heater that leaks slowly can spread a long way before anyone sees the surface wet.
A floor that is level looks dry at the edges while water is sitting under the flooring. A vinyl sheet or a laminate plank can lift at its seams and let water pass beneath it, and a carpet can wick it along the pad. The crew reads the floor across its full width, not only under the unit.
Cabinets, shelving and the base of a wall also soak up water from the floor. The bottom of a cabinet is often the place a crew finds the wettest material, because the water has collected there out of sight.
How long should a closet or garage floor stay open to dry?
Until the readings say it is dry, not until the surface looks dry. Floors, subfloors and the base of walls are checked on each visit, and the drying equipment stays in place until those readings reach the dry level. The time depends on what the water reached.
A concrete slab can hold water for a long time, and it is read the same way as a wood subfloor, with a meter and a check on each visit. A closet with a wood floor and a plywood subfloor behaves differently, because the water can soak into the wood and stay there.
The crew explains the readings at each visit, so you can see the progress. If a material is not drying, the crew explains why, and whether it has to come out. Keeping the area open and the air moving is the main thing that helps.
What should a homeowner check after a heater has been replaced?
Check the drip pan, the drain line, the relief valve and the floor beneath the new unit for any sign of water in the first days. A new heater sitting on a floor that was not fully dried can cause the same problem again, so the drying should be finished first.
Look at the floor and the lower wall after the first few heating cycles. A drain line that is blocked or a pan that is not connected will show as water in the pan, and a small amount is worth reporting at once.
Keep the record of the drying and the plumber's invoice with the heater's paperwork, so the next person who looks at the closet knows what was done and where the water went.
