More Information on Stack Pipe Connectors:
We supply a wide and extensive array of waste traps, including anti-siphon units and stack pipe connectors, to fit applications from bathrooms to wet rooms and kitchen sinks to washing machines.
All water using fixtures and appliances inside a house needs a water trap at the waste pipe to give a water seal into the drains or atmosphere, this prevents smells, bacteria and insects entering the property. Most modern waste plumbing (besides W.C.s) utilise 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 use 50mm (2 inch) diameter pipe to avoid siphon effect once the waste is used. The dimensions quoted are the internal 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 may not be interchangeable. One of the most important facets of waste water traps is the depth of seal.
Typically the waste pipe fits to the trap by a twist coupling (with a compression seal ring) or a push fit 'O' ring coupling - there is not much to select between the two types.
