The Davant 21.5mm Solvent Overflow 45° Elbow is a reliable and easy-to-use fitting designed to connect two overflow pipes at a 45-degree angle. Ideal for systems where a straight run isn’t practical, this elbow helps you navigate around corners or obstacles while maintaining a smooth, efficient flow path for excess water.
This fitting is typically used in overflow and condensate systems, such as those connected to cold water storage tanks, cisterns, or other low-pressure drainage setups. The 45-degree angle provides a gentler change in direction than a 90-degree elbow, which can improve water flow and reduce the risk of blockages over time.
Made for use with standard 21.5mm solvent weld pipe, the elbow is installed using solvent cement, creating a permanent and watertight seal. The black finish offers a clean, professional look—particularly suited for external or visible pipework installations.
Whether you’re a professional plumber or a DIYer handling your own overflow system, this 45° elbow offers a practical, durable solution for building or modifying pipe runs in tight or tricky spaces.
Frequently Asked Questions
What is the benefit of using a 45° elbow over a 90° elbow?
A 45-degree elbow offers a smoother change in direction, which helps maintain better flow and reduces the risk of clogging—especially in overflow systems where gradual movement of water is preferred.
Is this fitting compatible with white 21.5mm pipe?
Yes, while the fitting itself is black, it can be used with both black and white 21.5mm solvent weld pipes. The only difference is cosmetic, so it depends on your visual preference for the installation.
How is this elbow installed?
This is a solvent weld fitting, so it requires solvent cement. Apply the cement to both the inside of the elbow and the outside of the pipe, then push them together firmly. Once set, the joint will be secure and leak-proof.
