Davant 21.5mm Solvent Overflow Straight Tank Connector

The Davant 21.5mm Solvent Overflow Straight Tank Connector is a simple yet essential component designed to provide a secure and watertight connection between a pipe and a water storage tank. Whether you're working on a domestic cold water system, an overflow pipe for a loft tank, or a small garden water butt, this fitting makes installation straightforward and reliable. Designed for use with 21.5mm solvent weld overflow pipe, this straight connector is available in both black and white finishes to match the surrounding pipework and installation environment. It provides a clean and professional look while delivering dependable performance over time. This connector is solvent weld compatible, meaning it is intended to be permanently bonded to plastic pipe using solvent cement. Once applied, the joint becomes strong and leak-resistant, ideal for long-term applications where durability is key. The straight-through design ensures an uninterrupted flow path, helping to manage overflow efficiently and avoid unwanted water buildup. Suitable for both residential and light commercial systems, this tank connector is commonly used in vented cold water storage tanks, cisterns, or any overflow installation requiring a reliable through-tank connection.

Frequently Asked Questions

What is this tank connector typically used for?

It’s used to connect an overflow pipe to a water storage tank or cistern, allowing excess water to safely exit the tank without causing flooding or overfilling.

Is this connector suitable for both indoor and outdoor tanks?

Yes, it can be used in both indoor and sheltered outdoor applications. For outdoor use, ensure the installation is protected from harsh UV exposure or use the black version for improved UV resistance.

How is the pipe connected to the fitting?

This is a solvent weld fitting, so the pipe is permanently bonded using solvent cement. Apply the cement to both the inside of the connector and the outside of the pipe, then push them together for a strong, watertight seal.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
