1. Drainage through the Main Drainage Outlet
It is advisable to spend a more time getting the waste pipes positioned properly so the machines waste can be taken via its own trap to the main drainage outside. There are many ways to remove waste water once the machine waste pipe is fixed, these include connectingA�waste pipes to main drainage, fitting a kitchen sink waste pipe, fitting a kitchen sink,A�or plumbing in aA�washing machine or dishwasher.
2. The Better Fittings to Use
A washing machine or dishwasher waste is usually made with 40mm plastic pipe. It is advisable to use solvent welding or compression fittings with the waste pipe as once it is made, these is less chance of defective joints. Because of health and safety regulations a dishwasher must only be plumbed in to a cold water supply. This is so the machine can heat the water to a recommended minimum of 120 degrees Fahrenheit which is designed to eliminate all bacteria within the machine. The washing machine waste pipe will normally have the trap at the bottom. The reason for the trap is to stop foul air getting back into the room. The washing machine waste pipe, once installed, must deliver its water to the foul drainage system outside your home. This is the same system which takes the toilet and basin waste.
3. Best Practice for Waste Pipe Positioning
It is advisable to place the top of the waste pipe to a level which is 100mm under the worktop. If there is no worktop then the top of the waste pipe should finish at approximately 50mm down from the top of the washing machine. The washing machine waste hose usually comes with a pre set bend which takes the hose into the stand pipe approximately 200mm. The pipe should be clipped to the wall at least twice in its vertical length and at every 350mm along its horizontal length. Any sagging of the pipework can lead to puddles of stagnant water in the pipe which can leave unpleasant smells.
4. The Benefits of a Self Sealing Waste Trap
An excellent way of connecting washing machine and dishwasher wastes is by using an in-line, self sealing waste trap. These consist of a pipe shape, about 300mm long which fit onto a standard 40-45 mm pipe with a compression fitting. They consist of a thin membrane which opens to allow the waste water through but immediately closes, to stop foul air entering. This waste is called a self sealing waste valve.
Self sealing waste traps can be put on horizontally or vertically and can be used in bathrooms as well as kitchens. Bends and adapters can be provided with the fitting so it can be fitted in virtually any situation. Installing a self sealing vent, is advisable as it reduces negative pressure in the waste system, and can be used to remove the noises associated with active pipes and basins.
