Our FloPlast underground drainage bends are available with either a single or a double socket. The...Our FloPlast underground drainage bends are available with either a single or a double socket. The sockets are a simple push fit design with a captive rubber seal that is housed inside a moulded recess. Drainage bends have a variety of used depending upon their angle. 87.5 degree bends are most commonly used vertically at the foot of a soil pipe or a rainwater pipe, whilst 45 degree bends are often used at the entry and exit points of an inspection chamber. 30 and 15 degree bends are generally used in the horizontal plane when a slight change of direction is required. We always recommend the use of silicon lubricant with all push fit drainage fittings as it makes installation easier and maintains and enhances the performance of the seal in the long run. This terracotta PVC single socket bend from FloPlast is ideal for carrying waste safely and cleanly away from your home.

FAQs
What is the purpose of a 30-degree drainage bend?
A 30-degree drainage bend is used to create a gradual change in direction for underground drainage pipes, typically in horizontal runs, allowing for smooth flow and avoiding sharp turns that can cause blockages.
How do I ensure a watertight seal?
A watertight seal is achieved by ensuring the pipe end is clean, the rubber seal is lubricated with silicon lubricant, and the pipe is pushed firmly and squarely into the socket until fully seated.
Can I use solvent cement with this fitting?
No, this FloPlast drainage bend features a push-fit design with a rubber seal and is not designed for use with solvent cement. Use only the specified push-fit connection method.
What is the diameter of this drainage bend?
This drainage bend has a diameter of 110mm, which is a standard size for most underground drainage and sewer applications.
Do I need to use lubricant?
While not strictly mandatory, using silicon lubricant is highly recommended. It makes installation easier, prevents damage to the rubber seal during insertion, and helps maintain the seal's performance and longevity over time.
What is the difference between a single and double socket bend?
A single socket bend has one end with a socket for connecting to a pipe spigot. A double socket bend has two sockets, allowing for connections at both ends without needing separate couplings or fittings.
Can this bend be used for rainwater or soil pipes?
Yes, this 110mm drainage bend is suitable for both underground rainwater drainage and soil pipe systems, provided the connections are made correctly.
Troubleshooting
Difficulty pushing pipe into socket
Ensure the pipe end and the rubber seal are adequately lubricated with silicon lubricant. Check for any obstructions inside the socket or on the pipe spigot. Verify that the pipe is correctly aligned and not at an awkward angle.
Leak detected at the joint
The pipe may not have been fully inserted. Gently pull the pipe out slightly and re-insert it firmly. Check the rubber seal for damage or debris and clean if necessary. Ensure the connecting pipe is not stressed or misaligned.
Pipe does not seal properly
Confirm that the rubber seal is correctly seated within its recess in the socket. Ensure the spigot of the connecting pipe is clean and free of damage. Re-apply lubricant and ensure a firm, straight push to engage the seal.
Pros and Cons
Pros
Easy push-fit installation saves time and labor.
Captive rubber seal ensures a reliable, watertight joint.
Durable PVC material offers long-term performance.
Standard 110mm diameter ensures broad compatibility.
Specific 30-degree angle allows for precise drainage line adjustments.
Cons
Requires careful alignment during installation to prevent seal damage.
May require silicon lubricant for optimal installation and seal longevity.
Not suitable for solvent-weld systems.
Limited to its specific 30-degree angle; other angles may be needed for different configurations.
Setup, Compatibility & Care
Setup:
Ensure the ends of the pipes or fittings to be joined are clean, free from dirt, and chamfered (slightly angled) on the outer edge.
Apply a thin layer of silicon lubricant to the rubber seal and the outside of the pipe spigot.
Push the pipe spigot firmly into the socket of the bend until it is fully home and the rubber seal is properly engaged.
Compatibility:
This bend is designed for use with other 110mm diameter underground drainage systems.
It is compatible with push-fit fittings and pipes featuring a spigot end.
Ensure any connecting pipes or fittings are also suitable for underground drainage applications.
Care:
Underground drainage systems are generally maintenance-free. However, occasional flushing may be required to prevent blockages.
Periodically check for signs of leakage around joints, although the push-fit system with a captive seal is designed for durability.
Avoid exposing the fitting to excessive heat or harsh chemicals that could degrade the PVC or rubber seal.
