Product Information
Full details
The Kayflow 40mm Push-Fit 45 Degree Swept Bend is an essential component for DIYers and professional plumbers looking to install or modify domestic grey water drainage systems for sinks, showers, and appliances. Its primary benefit is a tool-free, adhesive-free installation process that ensures a watertight seal, though users should ensure they are using compatible 40mm pipe sizes to prevent leaks or loose joints.

FAQs
Does this require glue?
No, this is a push-fit fitting that relies on integrated rubber seals to create a watertight connection.
Can I use this for hot water?
Yes, the material is engineered to handle typical temperatures found in domestic grey water systems such as dishwashers and washing machines.
Is this compatible with solvent-weld pipes?
This fitting is designed for 40mm push-fit pipes. While some pipes are universal, always check your pipe's diameter and tolerance to ensure it creates a firm seal with the internal O-ring.
Can I remove the bend after installation?
Yes, the joints are fully demountable, allowing you to disassemble and move the fitting as needed for maintenance or layout changes.
What is the warranty period?
This product is backed by a 10-year Kayflow guarantee against manufacturing defects.
Troubleshooting
Joint is leaking
Check that the pipe is pushed in fully past the seal and ensure the pipe end is not scratched or burred.
Pipe is very difficult to insert
Ensure the pipe is 40mm diameter and clean. Apply a small amount of silicone lubricant to the end of the pipe.
Joint feels loose
Verify that you are using standard 40mm push-fit pipe; thinner-walled or metric pipes not designed for this system may not seal properly.
Pros and Cons
Pros

- Swept design minimizes blockages
- Durable construction with 10-year guarantee

- Black finish may be visible in exposed aesthetic setups
Setup, Compatibility & Care
To ensure a successful installation, follow these steps: first, ensure the pipe end is clean and cut squarely. Use a file or deburring tool to remove any sharp edges from the pipe, as rough edges can tear the internal rubber ring, leading to slow leaks. Lubricate the pipe end slightly with a silicone-based grease if the fit is too tight. The system is designed for 40mm waste pipes meeting BS EN 1451 standards. To care for the system, periodically check the joints for moisture, though generally, the push-fit mechanism is maintenance-free. If you need to reconfigure your plumbing, simply pull the joint apart with a slight twisting motion to release the pressure on the seal.
