Plumbright Southern provides boiler repair in Hedge End by Gas Safe registered engineers. If you have no heating, no hot water, low pressure or an error code on the display, we find the fault and fix it.
Most breakdowns come down to a handful of causes: low pressure, a failed pump or fan, a faulty diverter valve, a blocked condensate pipe or an ignition problem. The display code and the way the boiler behaves point us in the right direction, and we test parts before replacing anything.
More Information
Before calling, check the pressure gauge. Most boilers like to sit between 1 and 1.5 bar when cold. Make sure the gas is on at the meter and the thermostat is turned up. In freezing weather, a frozen condensate pipe outside can stop the boiler, and pouring warm water over it can help.
If a boiler is fairly new and the fault is a single part, a repair is usually the sensible choice. If it is old, keeps breaking down or parts are hard to find, money spent on repairs can add up fast. We give you an honest view of both options so you can decide.
STILL NOT SURE?
Boilers lose pressure through a leak somewhere in the heating system, a faulty pressure relief valve, or after radiators have been bled. You can usually top it back up using the filling loop under the boiler. If it keeps dropping, there is a fault that needs a Gas Safe engineer to find.
If the boiler shows a fault code and locks out, it is protecting itself, so do not keep resetting it over and over. Turn it off and call a Gas Safe engineer. If you smell gas or see black marks around the case, stop using it and call the gas emergency line.
Many boiler repairs are done in a single visit, often within an hour or two once the fault is found. If a part needs ordering, we make the boiler safe and come back to fit it when it arrives. We will tell you what to expect before we start any work.
