Trebles BoostBox

The Trebles BoostBox is a fully packaged cold water Cat-5 booster set designed to deal with low pressure without overcomplicating the job. It comes complete with pumps, an integrated 18L break tank, and controls, so there's no need to build a system on site. It's compact, tidy, and ready to install.

Available in single- or twin-pump options, it delivers consistent performance with a fixed-speed setup. The built-in Category 5 AB air gap provides full backflow protection, making it suitable for applications where compliance is essential.

It also includes features you'd expect, such as auto-changeover (twin), dry run protection, solenoid fill for fast filling, and a digital controller with error logging - so it runs reliably without needing constant attention.
