Why Is My Boiler Leaking Water?

Boilers have long service lifespans because they have few mechanical parts in them that can wear down from use. Furnaces, on the other hand, have multiple motors and fans that will often require repairs if the heater does not receive regular maintenance. If you have a boiler keeping your house warm, you can expect many years of quality from it, with only an occasional repair call.

However, you will still need to have regular maintenance done on it, because boilers do have some specific repair needs that can crop up unless they are looked after. Leaking water is perhaps the problem that comes up the most often. Although your boiler will probably drip a little water from its pressure release valve (which is a normal part of its operation), leaking anywhere else means there is a problem. Call up repair professionals, like those at Ardon Maintenance, and have the issue looked at immediately. Leaking water not only means a boiler headed for trouble, but it could also mean water damage to building material and the growth of mold and bacteria.

There are a number of reasons a boiler may start to leak:

  • Corrosion: The number one enemy your boiler faces is corrosion, the chemical process that results from the mix of iron, water, and oxygen. An anode rod atop the hot water tank helps to prevent corrosion from entering the tank. If the rod rusts through, then you can expect corrosion problems to begin to affect the boiler. Corrosion weakens metal until it crumbles apart, but you’ll see leaking far earlier than that. Try to have corrosion remedied as soon as you can, because if it spreads too extensively you may need to have the water tank replaced entirely.
  • High water pressure: The water pressure inside the tank and the pipes should remain at a steady level. However, breaks in the expansion tank, limescale inside the boiler, or the influx of sediment can all cause the boiler to overheat—and the pressure to spike. Increased pressure will cause leaks to spring up all across the piping. You will not only need the leaks sealed, you will also need professionals to find the reason for the increase in pressure and fix it.
  • Poor initial installation: It’s important to have expert technicians install a boiler, because a badly done amateur job often means inferior connections between the tank and the lines. Sloppy soldering jobs and loose valves will cause constant leaks. Professionals may be able to perform enough work to fix this, or you may need to have a completely new installation done. We often find this problem occurs for people who inherited a boiler with their home.

Whatever the cause of the leak, leave the detection work to the technicians. You don’t want to attempt boiler repairs on your own: you might cause the leaks to become worse. Contact Ardon Maintenance when you first detect leaks, and let us stop them before they spread. We’re ready 24-hours a day to assist you, so schedule your boiler repair in Madisonville today.
