Pump Controllers

We have a wide range of pump and mains-water top-up controllers in stock (this section of our website is being added to regularly).

If you have a domestic or commercial rainwater harvesting controller that is broken or malfunctioning (or indeed from a company that is no longer trading like ECOVAT or SpinFlow), please contact us as we may be able to repair or find a replacement unit.
