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.
