A boiler is a great alternative to a traditional hot water heater for many people, and like all other household appliances, it requires regular maintenance. At All Hours Plumbing, Heating & Air, we’re your one-stop shop for boiler installation, service and repairs when they become necessary.

You can be a big help here as well – identifying boiler issues before they become more serious is often up to the homeowner as the first line of defense. Here are a few common signs that your boiler might be in need of service or repair.

No Hot Water

The most obvious and noticeable sign is when you notice no hot water, or heat from your radiators. This could mean a basic thermostat issue, so check this first, but otherwise it could be something more serious. Also check for low pressure on your boiler’s gauge – if it’s lower than 1, it could just be a pressure adjustment that’s needed. If not, the most likely culprit is a broken part or a valve that needs replacing.

Low Pressure

If hot water is working, but is coming out of pipes very weakly, this is another telltale sign. This could mean an issue with the entire home, so check the main line’s pressure first here. If not, a common reason for low pressure is a blockage somewhere in the system, which could be caused by a leak in some cases.

Banging Noises

Strange noises from the boiler can be a signal of air in the system – it will often create gurgling, whistling or banging noises. These sounds could also mean that pipes aren’t fitted correctly and are knocking together as air and water goes through them, in which case your pipes would need to be adjusted. Banging pipes could also be a sign of pump failure, which would mean a replacement was needed.

Leaks or Drips

Hot water corrodes metal faster than cool water, so leaks caused by corrosion are pretty common. Check the boiler for any leaks or pooling water in the area.

Pilot Light

If you notice the pilot light continuously going out, first check your gas supply to make sure there are no issues there. If this isn’t the issue, it could be due to a wind draft, a build-up in the pilot light, or a broken thermocouple.
