We have replaced our down pipe diverter to the water butt. Until now we had issues with blockages in our drain pipe. It has never been easy to take apart and clean/clear the blockage and put it all back together. We have now installed the freeflush version of the diverter which allows very easy pull out of a filter for quick clean and back in.....we are so pleased with the quality and easy use of the product. It was easy to instal, purchase, website was full of information and detail and the delivery was quick. We can highly recommend the product and are very happy to recommend freeflush.
