ADP wastes and traps
ADP wastes and traps are the plumbing fittings that sit beneath a basin, bath, sink or floor drain to manage water leaving the fixture. A waste is the fitting at the drain outlet itself, controlling how water exits the fixture, while a trap sits in the pipework below and holds a small amount of water to prevent sewer gas from coming back up through the drain into the room. The two work together, and most fixtures need both to function correctly and safely.
What a waste does
The waste is the visible fitting at the base of a basin, bath or sink, and in many cases includes a plug or pop-up mechanism to hold or release water. Choosing a waste that matches the outlet size of your fixture is essential, since a mismatched size will either not seal properly or will not fit the fixture at all.
What a trap does
A trap is installed in the pipework beneath the waste and is designed to always hold a small amount of water in a bend. This water seal blocks sewer gas from travelling back up through the pipe and into the bathroom or kitchen. Traps are a plumbing code requirement on most fixtures, so if you are replacing or renovating around an existing basin, bath or sink, a compatible trap needs to be fitted along with the waste.
Buying considerations
Outlet size is the first thing to check, since wastes and traps need to match the outlet size of the specific fixture they are installed on, whether that is a basin, bath, sink or floor drain. Getting this wrong is one of the most common fitting errors, so confirm the outlet diameter of your fixture before ordering.
Finish is also worth considering if the waste will be visible once installed, such as on a basin or bath. Matching the waste finish to your tapware keeps the fixture looking coordinated, rather than having a waste finish that stands out against the surrounding tapware and fittings.
- Confirm the outlet size of your fixture before choosing a waste or trap
- Check that a trap is fitted alongside the waste to prevent sewer gas entering the room
- Match waste finish to tapware where the fitting will be visible
- Consider floor waste requirements separately from basin, bath or sink wastes, as sizing and fitting can differ
Frequently Asked Questions
What is the difference between a waste and a trap?
A waste is the fitting at the drain outlet of a basin, bath or sink, controlling how water leaves the fixture, often with a plug or pop-up function. A trap sits in the pipework beneath the waste and holds water in a bend to stop sewer gas from coming back up through the drain.
Do I need both a waste and a trap?
Yes, most fixtures need both a waste and a trap to function correctly, since the trap is what prevents sewer gas entering the room, and it is generally a plumbing code requirement. If you are replacing a waste, check whether the existing trap is compatible or also needs replacing.
How do I know what outlet size waste to buy?
Check the outlet diameter of the specific fixture the waste is going into, whether that is a basin, bath, sink or floor drain, since wastes and traps are sized to match. Ordering the wrong size is one of the most common fitting mistakes, so confirming this before purchase saves a return trip.
Should the waste finish match my tapware?
Where the waste is visible, such as on a basin or bath, matching its finish to your tapware gives a more coordinated look in the finished room. This is worth considering during the planning stage rather than after fittings are already installed.
Are floor waste requirements different to basin or bath wastes?
Floor wastes can have different sizing and fitting requirements compared to basin, bath or sink wastes, so it is worth checking the specific product details for a floor waste separately rather than assuming the same waste will suit both applications.
