Description
The
160mm double socket Y branch is an equal underground drainage fitting designed to connect a full-size 160mm branch into a compatible 160mm main drainage run. This
160mm equal Y branch provides a practical
160mm underground drainage branch with a gradual
45 degree drainage Y branch configuration, creating a reliable
160mm drainage Y junction for foul-water and surface-water systems. The 45° Y configuration introduces the branch into the main drainage run at a shallower angle than a near-90° T branch, helping provide a smooth directional transition through the junction.
160mm Double Socket Y Branch
The
160mm double socket Y branch is designed for larger underground drainage systems where both the main pipe and incoming branch are nominal 160mm. The double-socket connection arrangement allows the fitting to integrate with compatible pipework while keeping the branch connection full size.
Choosing a 160mm Double Socket Y Branch
Choose the
160mm double socket Y branch where a 160mm drainage line needs to enter a 160mm main run at a 45° angle. If the branch connection is smaller, such as 110mm, choose a suitable unequal reducing Y branch instead.
160mm Equal Y Branch
The
160mm equal Y branch uses the same nominal diameter throughout the main run and branch connection. This differs from an unequal branch, where the incoming pipe is smaller than the main drainage line.
160mm Equal Y Branch Applications
The
160mm equal Y branch can be used within suitable applications including:
- 160mm foul-water drainage
- Surface-water drainage
- Rainwater drainage systems
- Commercial groundworks
- Larger domestic drainage systems
- Drainage extensions and alterations
- Main underground drainage runs
160mm Underground Drainage Branch
The
160mm underground drainage branch provides an additional full-size connection within compatible 160mm gravity drainage systems. It is particularly useful where two larger drainage runs need to combine within the same underground network.
Installing a 160mm Underground Drainage Branch
Before installing the
160mm underground drainage branch, check that the sockets, sealing rings and adjoining pipe ends are clean and free from grit or damage. Use suitable underground drainage lubricant where required and insert prepared pipe or fitting spigots squarely into the sockets without displacing the seals.
45 Degree Drainage Y Branch
The
45 degree drainage Y branch introduces the connecting pipe into the main drainage run at a gradual angle. This can provide a smoother directional transition than a near-right-angle T branch and is useful where the drainage route allows a shallower entry angle.
Using a 45 Degree Drainage Y Branch
When positioning the
45 degree drainage Y branch, consider the direction of flow, pipe falls and available installation space. The fitting and adjoining drainage pipework should be correctly supported and bedded before backfilling.
160mm Drainage Y Junction
The fitting creates a practical
160mm drainage Y junction where an additional 160mm line needs to enter the main underground drainage run. A
160mm drainage Y junction can be used across domestic, commercial and groundwork installations where a full-size branch connection is required.
Installing a 160mm Drainage Y Junction
Make sure the junction is orientated in the intended direction of flow and that all surrounding pipework is correctly aligned before completing the connection. The
160mm drainage Y junction should not be forced into alignment through unsupported or incorrectly positioned pipework.
Double Socket vs Triple Socket Y Branch
This product is the double-socket version and uses a different connection arrangement from a triple-socket Y branch. A triple-socket fitting provides sockets at all three openings, while a double-socket version uses a combination of socket and spigot connections. Choose the connection arrangement that best matches the surrounding underground drainage system.
45° Y Branch vs 90° T Branch
A 45° Y branch introduces the incoming drainage pipe at a shallower angle than a near-right-angle T branch. The correct fitting depends on the route of the pipework, direction of flow, available space and overall drainage design.
Equal Branch vs Unequal Branch
This fitting is an equal branch because the main run and branch are all nominal 160mm. If a smaller 110mm pipe needs to enter a 160mm main drainage run, choose a 160mm-to-110mm unequal branch instead.
Push-Fit Underground Drainage
The socket connections use ring seals for straightforward push-fit jointing with compatible underground drainage pipe and fittings. Keep all seals and jointing surfaces clean throughout installation and use suitable drainage lubricant where required.
PVC-U Underground Drainage
This type of branch is used within compatible PVC-U non-pressure underground drainage and sewerage systems. PVC-U is widely used below ground because it provides a lightweight, corrosion-resistant and durable drainage system for foul-water and surface-water applications.
BS EN 1401 Underground Drainage
160mm underground drainage fittings of this type are used within PVC-U systems manufactured to BS EN 1401-1 for non-pressure underground drainage and sewerage. Always check compatibility where pipe and fittings from different drainage systems are being combined.
Preparing Drainage Pipe for Installation
If drainage pipe needs to be cut, make a clean square cut and remove any burrs from the prepared end. Chamfer the edge where required before insertion to help protect the ring seal and keep all jointing surfaces clean.
Bedding and Support
The branch and adjoining pipework should be evenly supported using suitable underground drainage bedding. Avoid leaving the fitting suspended between unsupported pipe sections, as movement after backfilling can place unnecessary stress on the joints.
