More Information on Shower Traps:
A shower trap is a plumbing fitting designed to reduce drain clogs. In plumbing language, the term "shower trap" describes a unit installed between the first horizontal drain line and the secondary horizontal line. Every water fixture in your home is directly attached to a secondary drain pipe. Before wastewater enters the drain line, it has to travel through the trap. After a water disposal, like a shower, the water sits in the trap fixture blocking gasses from escaping.
We supply a wide and extensive array of waste traps, such as shower traps and universal flexible wastes, to fit anything from bathrooms to shower rooms and kitchen sinks to washing machines. All water using fixtures and appliances within a house must have a water trap at the waste pipe to give a water seal into the drains or air, this prevents smells, bacteria and insects entering the property. Most contemporary waste plumbing (besides W.C.s) use either 32mm (1.25 inch) (for hand basins) or 40mm (1.5 inch) (such as sinks, bathrooms, showers, dishwashers, washing machines) plastic pipe and fittings (including traps); pipe runs over 2m (6 feet) can utilise 50mm (2 inch) diameter pipe to avoid siphon effect when the waste is utilised.
The dimensions quoted are the inner pipe dimensions (and also the waste outlet in the sink/basin/bath etc), the outer diameter of the pipework does vary between different producers thus pipes and fitting might not be interchangeable. Among the most important aspects of waste water traps is the depth of seal. Typically the waste pipe fits to the trap with a twist coupling (using a compression seal ring) or a push fit'O' ring coupling - there is not much to select between the two types.
