Turn off the water at your stopcock. It's often under the kitchen sink, but can be in a cupboard, garage or where the supply enters the house. If water is near electrics, keep away and switch off at the consumer unit if it's safe to do so. Catch what you can with towels and buckets, then call.

Southampton, Portsmouth, Winchester, Eastleigh & surrounding areas. If you're just outside, call and ask.

Usually there's air trapped in the radiator. Bleeding it with a radiator key often fixes it. If you have a sealed system, check the pressure gauge afterwards, as bleeding can lower it.

On a sealed system, pressure that keeps falling usually means water is escaping somewhere: a leak, a weeping valve, or a fault such as the pressure relief valve or expansion vessel. It's worth getting it checked rather than repeatedly topping it up.

Yes. I offer boiler servicing and installation, carried out by Gas Safe registered engineers.

Often, yes. This usually means replacing a vented cylinder and loft tanks with an unvented cylinder, which gives stronger showers and taps. Whether it suits your home depends on your mains water pressure and flow, which I'll check first.

It's a sealed hot-water cylinder fed straight from the mains, with no cold-water tank in the loft. Because it stores hot water at mains pressure, you get better flow at taps and showers, and it frees up loft space.

G3 is the part of the Building Regulations (Approved Document G) that covers hot-water storage. Unvented systems hold hot water under pressure, so they have safety devices that must be fitted and set correctly.

By law, unvented cylinders over 15 litres must be installed by a competent person, which in practice means someone holding a G3 unvented hot-water qualification. The installation also needs to be notified to Building Control.

Most manufacturers recommend a service every year, and it's often a condition of the cylinder's warranty. A service checks the safety valves, expansion vessel and pressure settings.

The tundish is the small funnel on the pipe near your cylinder. Water running through it means a safety or relief valve is releasing water, often because of a pressure or temperature problem. It shouldn't be ignored: get it looked at by a G3 qualified engineer.

If it's hot water or steam, switch off the water heating (immersion and boiler) and call.
