Common plumbing and heating faults

Your plumbing system can suffer from a wide range of faults, but they fall into four main categories.

Taps and valves

Taps and valves control the flow of water into and through the home. They may drip, causing stains and overflows, or may jam open or closed, or be hard to operate. Taps might need maintenance or replacement, depending on the severity of the problem.

Supply pipes

Supply pipes distribute water to wherever it is needed. They may leak, due to perforations developing in the pipe or faulty seals at pipe connectors. They may also gradually become blocked by scale, caused by hard water. Both faults are easily remedied, although leaks demand swift damage limitation – see Plumbing emergency action.

Storage tanks

Storage tanks hold cold and hot water. They may develop leaks or, in the case of the hot tank, may become inefficient due to a build-up of limescale. Replacement is the only long-term solution.

Waste pipes

Waste pipes convey used water from appliances, toilets and WCs to the household drains, via U-shaped traps designed to keep drain smells out of the house. They can become blocked, causing overflows, but most blockages can be cleared easily.


  • If a fault causes water to escape, aim to stop the flow as quickly as possible.
  • Make sure you know in advance where the system's main on/off and flow controls are located.
  • Empty leaking water storage tanks and supply pipes by turning off the main stoptap and opening cold taps, or by attaching a garden hose to a drain valve and opening the valve with pliers or a spanner. Lead the hose outside the house.
  • Clear blocked waste pipes and traps by dismantling, plunging or rodding.

The boiler

The boiler heats the system (and may also provide domestic hot water and heat to central heated radiators). It contains a number of parts that will need regular maintenance and eventual replacement and this is a job for a professional. Annual servicing will keep the boiler in good order.

The radiators

The radiators transmit heat to individual rooms. They sometimes develop pinhole leaks due to corrosion, and may trap air, gas or sludge (by-products of corrosion), all of which can cause uneven heating or banging noises when in use. The use of a corrosion inhibitor or leak sealer will help to prevent or cure these problems.

The pump

The pump circulates heated water round the system. It may become jammed or noisy in operation, or may simply fail altogether. Regular operation and cleaning help to prevent problems, but replacement is usually straightforward.

The heating system

A central heating system consists of five main components, each of which can malfunction or fail. expansion tank) tops up any water lost from the heating system through leaks or evaporation. The tank itself may also develop a leak and need replacing. The ballvalve that refills it may jam through lack of use, causing an overflow or allowing air to be drawn into the radiators and pump. A ballvalve can be repaired or replaced.

The controls

Controls operating the heating system include a programmer, thermostats and motorised valves. Faulty wiring may lead to malfunction, and mechanical failure may be remedied through servicing or replacement of the faulty control.


  • If the system overheats or the pump fails, turn off the boiler.
  • Turn off the gas at the meter immediately if you smell a gas leak and call the Transco gas emergency number (0800 111 999).
  • Until you can make a repair, drain leaking pipes, radiators and hot water cylinders via the relevant drain cock.
