Push Fit Waste

Plumbing Push Fit Waste

Waste pipe systems can be connected up using simple push fit fittings. The fitting simply pushes on to the waste pipe and an internal sealing ring is squeezed against the pipe to form the seal. This is a popular alternative to the solvent weld type.

Radiator Valves

Plumbing Radiator Valves

From standard white panel radiators through to elaborate and stylish designs, there is now a huge choice of style as well as materials for radiators. Whichever type is used, it is important to check the potential heat output available and to match this with the heat loss of the room.


Plumbing Radiators

Radiator valves control the flow of water in and out of radiators on a central heating circuit. A lockshield valve at one end is used to balance the system and a standard or thermostatic valve at the other end gives user control so that heat can be delivered as required.

Rainwater Goods

Plumbing Rainwater Goods

This section covers all items related to the discharge of rainwater form the roofs of buildings. They include the different guttering systems - gutters, connectors, brackets and outlets, as well as the downpipe used to carry the water to a suitable drain discharge point.

Soil and Vent

Plumbing Soil and Vent

Foul water discharged from toilets is carried via a soil pipe to a suitable connection point for discharge into the sewers. The term soil and vent pipe comes from the combined need to provide a method of allowing air into the pipe work to prevent siphonage of water traps.

Solder Fittings

Plumbing Solder Fittings

Copper pipes can be readily joined using integral solder fittings. Flux is applied to the pipe and fitting and, once assembled, the connection is heated with a gas torch to melt the solder. This solder flows from the integral ring to seal the connection between the two.

Solvent Weld Waste

Plumbing Solvent Weld Waste

Solvent weld waste pipes are commonplace. Before assembling the special plastic pipe and fitting, a special glue or solvent cement is brushed round both. Once assembled, the surfaces quickly bond with the cement forming a watertight seal.
