Common boiler repair issues

There are many issues that might necessitate a boiler repair in Cardiff, with some being less serious than others. While it is possible to correct some of these issues yourself, if you’re in doubt, we recommend getting a boiler repair company in, rather than risking further damage to the unit, or injury to yourself. Here are some of the more common boiler faults that we come across.

No heat or hot water

A common problem with boilers, and one with a multitude of possible causes, from motorised valve failure and faults with the thermostat, to broken airlocks or diaphragms within the boiler itself. Some of these parts may need replacing as part of your boiler repair in order to get things up and running again.

Leaking and dripping

Usually caused by one or more internal components having broken (such a pressure valve or a pump seal), a boiler leaking and dripping can come about through general wear and tear, or by running your boiler’s pressure too high. Since leaks only get worse, an urgent boiler repair is recommended.

Thermostat issues

If your thermostat is no long accurate, or if it switches the heating on or off when it isn’t meant to, it could be time to get it replaced. At Ray Leggett Plumbing & Heating , our engineers are experts at installing modern smart thermostats, including both hive and nest models, and will be happy to advise you on the matter as part of your boiler repair in Cardiff.

Bangs, gurgles, and whistling

Usually indicative of air in the system than needs to be released. Whilst it often sounds worse than it is, these noises can sometimes be a precursor to pump failure, especially in older boilers, so a boiler repair (or even replacement) might be advised.

Over 16 years’ experience

With over three decades of experience under their collective belts, our team of dedicated and qualified engineers have dealt with all of the boiler repairs listed above, and more. This level of experience in boiler repairs in Cardiff brings peace of mind to new and existing customers that our plumbers know what they are doing.
