    5/ 5

    Good value, works well so far and was easy to fit, with negative head pumps time will tell but so far working better than the one it replaced which was double the price

    Installed for a customer needing to boost their shower. Fitted pump in the loft and ran pipework down to the shower below. Looks good quality, easy to install and have had no complaints so far.
