Floor Waste Systems and Indirect Waste Pipes


Floor waste systems are required in restrooms and laundries to prevent sewage odors and water from entering other areas of your home. It is recommended to place the floor waste in an accessible location, prime it, and connect it to other drainage systems, if necessary.

Floor sinks are primarily used as an indirect waste receptor

Indirect waste pipes do not connect directly to the drainage system, but instead convey liquid waste into a plumbing fixture and then into the drain. Floor sinks, mop receptors, service sinks, and washing machine standpipe drains are all examples of indirect waste receptors. The primary purpose of a floor sink is to accept waste from a kitchen sink.

Despite their primary use as an indirect waste receptor, floor sinks are often equipped with traps. In some jurisdictions, these traps are not required until a distance of about five feet. In other cases, a floor sink can serve as a receptor and a trap is unnecessary. A floor drain also can serve as a receptor if it is designed properly. To be effective, an indirect waste drain should be fitted with a vent.

Indirect waste piping should have an air gap or break between the fixture outlet and the flood-level rim of the receiving sink. This gap or break must be at least 6 inches lower than the lowest floor drain. This gap is required to prevent sewage back-flow. Indirect waste pipes that discharge into a sewer must have an air gap at the rim of the receptacle.

They are required in bathrooms and laundries

In a bathroom or laundry, the drain should be situated so it does not back up into the house. These drains are generally installed in the center of the floor. Some new developments also include floor drains in the laundry. They are recommended for public toilet rooms with more than three urinals, although stall urinals are considered floor drains if they are built with a drainage system for the waste water.

Floor wastes are the last line of defense in case of flooding and protect the rest of the home. They should always have water in them, as this creates a seal and blocks sewer gasses. If you notice a bad smell emanating from the floor drain in your bathroom or laundry, it may indicate that your water trap is not working properly. To avoid this, you should also install an anti-odor barrier and an in-line odour filter.

They prevent water from getting into the rest of your home

If you’re worried about flooding, you should install floor drains in every room of your home. These drains are connected to the main sewer line. Because floor drains are typically the lowest drain fixture, they can catch excess water and prevent it from entering the rest of your home. To prevent sewer overflow, install a backwater valve near the floor drain. You can also designate a specific floor drain as a backwater valve.

They prevent sewage odors from entering your home

If sewage smells are a regular occurrence in your home, you’ll want to take action right away. If you’re experiencing smells from the sewer, consider a CCTV inspection. A CCTV inspection can help you find the source of the problem, and it’s one of the least expensive solutions. Sewage smells can have serious consequences, and you’ll want to address the problem as soon as possible.

Sewer odors come from the breakdown of human waste. These gases are toxic, but small amounts won’t harm you. But prolonged exposure can cause negative health effects. That’s why it’s so important to keep a proper floor waste system. If you have an old home, there’s a chance that the pipes are eroded and cracked. Another way to prevent sewer odors from entering your home is to install clean-out plugs. These plugs are essential for separating your indoor and outdoor sewer systems, but if they’re missing or broken, the sewer gas can seep in, leaving a lingering smell.

They help prevent water damage

Floor wastes are required for wet area rooms in Class 2 & 3 buildings and part 4 sole occupancy units. They prevent water damage to other sole occupancy units and common areas. BCA Vol 3 and AS3500 treat floor wastes as fixtures and regulate their size. There is no drainage requirement for these floor wastes, but they are necessary to meet CP2.1(j).
