Water Butt BSP Tank Connector Adapter

This BSP threaded tank connector adapter lets you add a reliable outlet to water butts, rainwater tanks and similar containers, helping you route water to a hose, irrigation pipework or other garden watering setups. It’s designed to give a tidy, secure connection through the tank wall and help reduce the risk of leaks when fitted correctly.

The fitting uses British Standard Pipe (BSP) threading and seals through the tank using washers and a locking nut. Options include threaded connectors, versions supplied with a quick connector, and a kit option that includes a valve for convenient on/off control.

It’s a practical choice for rainwater harvesting systems, garden irrigation, pond and pump pipe runs, and general water transfer where a through-tank connection is needed. Choose the correct BSP thread option to match the hole size in your container and the connection style you want.

Installation is straightforward: make sure the hole in the tank is the correct size, insert the fitting with the washer in place, tighten the nut to compress the seals, then attach your pipe and secure it with a suitable clip or cable tie. Check for leaks after filling and re-tighten by hand if required.
