Description
The
160mm 45 degree triple socket Y branch is an equal underground drainage junction designed to introduce a 160mm branch into a compatible 160mm main drainage run. This
160mm equal Y branch provides a practical
160mm underground drainage branch with three socketed connections, creating a reliable
triple socket drainage Y junction and
160mm 45 degree drainage junction for foul-water and surface-water systems. The 45° Y configuration introduces the branch into the main drainage line at a gradual angle, while the triple-socket design allows compatible plain-ended drainage pipe to connect directly into all three openings.
160mm 45 Degree Triple Socket Y Branch
The
160mm 45 degree triple socket Y branch is designed for larger underground drainage systems where both the main run and incoming branch are nominal 160mm. The three socketed connections make the fitting particularly convenient when building a new drainage junction from plain-ended pipe.
Choosing a 160mm 45 Degree Triple Socket Y Branch
Choose the
160mm 45 degree triple socket Y branch where a full-size 160mm branch needs to enter a 160mm main drainage line at a 45° angle. If the incoming branch is only 110mm, use a 160mm-to-110mm unequal Y branch instead.
160mm Equal Y Branch
The
160mm equal Y branch uses the same nominal pipe diameter on the main run and branch connection. This differs from an unequal or reducing branch, where the side connection 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 groundwork
- Larger domestic drainage systems
- Drainage extensions and alterations
- Main underground drainage runs
160mm Underground Drainage Branch
The
160mm underground drainage branch allows an additional full-size pipe run to connect into a compatible 160mm drainage system. It is particularly useful on larger gravity drainage layouts where multiple 160mm runs need to combine within the same underground system.
Installing a 160mm Underground Drainage Branch
Before installing the
160mm underground drainage branch, check that all sockets, seals and adjoining pipe ends are clean and free from grit or damage. Use suitable underground drainage lubricant where required and insert prepared pipe ends squarely into the sockets without displacing the sealing rings.
Triple Socket Drainage Y Junction
The
triple socket drainage Y junction has socketed connections at all three openings. This allows compatible plain-ended 160mm pipe to connect directly into both sides of the main drainage run and into the branch connection.
Triple Socket Drainage Y Junction Connections
Each socket uses a push-fit ring-seal connection designed for compatible underground drainage pipework. Keep the sockets, seals and pipe surfaces clean throughout assembly and avoid forcing misaligned pipe into the fitting.
160mm 45 Degree Drainage Junction
A
160mm 45 degree drainage junction introduces the connecting pipe into the main drainage line at a shallower angle than a near-90° T branch. The 45° configuration can provide a more gradual directional transition where the drainage layout and available installation space allow.
Using a 160mm 45 Degree Drainage Junction
When positioning the
160mm 45 degree drainage junction, consider the intended direction of flow, pipe falls and future maintenance access. The fitting and surrounding pipework should be correctly bedded and supported before the trench is backfilled.
45° Y Branch vs 90° T Branch
A 45° Y branch introduces the incoming pipe at a shallower angle than a near-right-angle T branch. The correct fitting depends on the route of the drainage pipework, flow direction, available space and overall system design.
Equal Branch vs Unequal Branch
This product is an equal branch because all three connections are nominal 160mm. Where a 110mm pipe needs to enter a 160mm main drainage run, a 160mm-to-110mm unequal branch should be selected instead.
Triple Socket vs Double Socket Y Branch
A triple-socket branch provides socket connections at all three openings. A double-socket version uses a different socket-and-spigot arrangement and may be preferable where one side of the surrounding installation already provides a suitable socket.
PVC-U Underground Drainage Systems
160mm 45° triple-socket branches of this configuration are used within PVC-U non-pressure underground drainage and sewerage systems. PVC-U is widely used below ground because it provides a lightweight, corrosion-resistant and straightforward push-fit drainage system.
BS EN 1401-1 Underground Drainage
Equivalent 160mm x 160mm 45° triple-socket branches are manufactured to BS EN 1401-1 for PVC-U non-pressure underground drainage and sewerage. Brett Martin, for example, lists the same 160mm equal 45° triple-socket configuration as product B6091. :contentReference[oaicite:1]{index=1} For general standards information, see the
BSI BS EN 1401-1 reference.
Preparing Drainage Pipe for Installation
If pipe needs to be cut before assembly, make a clean square cut and remove burrs from the prepared end. Chamfer the pipe where required to help protect the ring seal during insertion and keep all jointing surfaces clean.
Bedding and Support
The branch and adjoining drainage pipe should be evenly supported using suitable bedding material. Avoid leaving the fitting suspended between unsupported pipe sections, as this can place unnecessary stress on the joints after backfilling.
