Water that comes out of your appliances flows through the waste pipes, be it a solvent weld, push-fit waste or mechanical. It then flows out into to the main soil stack, and from there it goes right into the underground drain.

In the event of a ground-floor sink, basin or appliance it could flow to a trapped gully that's connected to the drain.

The gully is usually fitted with a metallic or plastic grid to prevent debris and leaves from obstructing it and falling into the trap. The drain itself will likely then run to a pit, sewer or septic tank buried in your backyard.

Wastewater Originates From:

⦁ Washing machines
⦁ Toilets
⦁ Dishwashers
⦁ Sinks
⦁ Showers and baths

All household appliances will be connected from the trap to the soil stack. The most commonly sold and installed variant is the solvent weld waste pipe fittings and pipes. This is because once installed; it provides the most robust - longest-lasting connection of all the different waste pipe fittings and variants.

The Different Types of Waste Systems Available Are:

⦁ 21.5mm: for overflows from boilers or cisterns.
⦁ 32mm: Found under low volume outlets and small hand basins.
⦁ 40mm: for kitchen sinks and bathroom waste pipe fittings.
⦁ 50mm: Usually found in industrial buildings, but can also be seen in residential houses.
⦁ 110mm: For sewer drains and plastic soil pipe.

As a guideline, you should stick to one system in your house and be consistent throughout - so, if you've got weld systems in your kitchen, it's a good idea to use weld systems in your bathroom too.

Compression fittings are, however, the only exception to the rule as they're universal. This means that they can be used on either solvent weld waste pipes (43mm external diameter), or push-fit waste pipes (40mm external diameter).

As the compression fittings are tightened, they'll secure the pipes using watertight rubber seals. These fittings are best for linking different pipes together.

The main disadvantage of these fittings is that they're bulky and expensive. It's ideal to go throughout the entire home with either solvent or push-fit systems and be consistent where possible.

Solvent pipes are not removable and adhesive. Push-fit pipes push together and are coated using a rubberised o-ring; these must pull apart very easily. Compression fit connections use a twist-lock link that must be un-tightened before they can be taken off.

Installation Guidelines

Solvent weld pipe requires a slightly more intensive installation — for example, the push-fit system, which simply pushes together. The solvent waste pipe joints will require proper preparation and then for solvent cement to be applied and left to dry for 24 hours.

The mechanical or compression waste system offers the best of both worlds. It's easy to install and adjust and also provides a firm seal. However, the compression waste system does come at an added cost due to the additional parts required during manufacture.
