Connecting a waste pipe to a drain typically involves using specific fittings like boss adapters and couplers to ensure a secure and watertight connection.
According to the provided information, to connect a typical internal waste pipe to a drain, fit the waste pipe to either a 32mm, 40mm or 50mm single socket boss adapter and then push it into an OsmaDrain Coupler. This method describes a common approach for connecting standard waste pipes to a larger drain system.
Understanding the Connection Process
The process described involves two main components: a boss adapter and a coupler.
1. The Waste Pipe and Boss Adapter
Waste pipes come in various standard sizes, commonly 32mm, 40mm, and 50mm in diameter for internal plumbing like sinks, baths, and showers. To connect one of these waste pipes into the side of a larger drainpipe (often called a 'soil stack' or a main drain run), a single socket boss adapter is used.
- Function: This fitting allows you to connect a smaller-diameter waste pipe securely into a pre-drilled hole (boss) on the side of a larger drainpipe.
- Sizes: As noted, these adapters are available for 32mm, 40mm, or 50mm waste pipes, matching standard sizes.
- Installation: The waste pipe fits into the 'socket' end of the adapter, and the adapter then connects to the boss on the drainpipe.
2. The Coupler (e.g., OsmaDrain Coupler)
Once the waste pipe is fitted to the boss adapter, the connection to the main drain system is completed using a coupler. The reference specifically mentions an OsmaDrain Coupler.
- Function: A coupler is a fitting used to join two pipes or a pipe to another fitting (like a boss adapter) together, creating a sealed joint. In this context, it seems to be the component that the boss adapter pushes into, likely connecting the adapter/waste pipe assembly to the drain system itself or a specific entry point.
- Installation: The reference states you "push it [the boss adapter with the waste pipe fitted] into an OsmaDrain Coupler." This suggests the coupler is the receiving end of the connection point on the drain side.
Step-by-Step (Based on Reference)
Based on the described method:
- Determine the size of your waste pipe (32mm, 40mm, or 50mm).
- Obtain a single socket boss adapter that matches your waste pipe size.
- Fit your waste pipe into the socket end of the boss adapter.
- Locate or prepare the connection point on the main drain system.
- Obtain an OsmaDrain Coupler suitable for receiving the boss adapter.
- Push the boss adapter (with the waste pipe attached) into the OsmaDrain Coupler to complete the connection.
This method provides a robust and sealed connection point for standard internal waste pipes entering a drain system.
