  • Mini saver double water butt kit 4/15/2018
    I am very satisfied with these two 100 litre butts. I did not have too much of a problem fitting the rainsaver device into the down pipe but you do need to remove the fittings that attach the down pipe to the wall so that both peices of cut downpipe can be pulled right away from the wall. Otherwise it would be all but impossible to insert the device between the two peices of downpipe. The other minor issue was that the rubber seals where the tap screws into the butts tended to distort as you screw the taps in. The secret is to smear the seals with vaseline and screw the taps in very slowlly so they do not grip the seals and distort them. The stands are three peices that clip together but I beefed them up with some gorilla tape and once the barrels are full they are rock solid. It rained quite heavily for two days after fittiing the butts and both are now completely full. They appear to be pretty robust and should last some years and I am looking forward to reduced water bills from now on. Overall, I can highly recommed this kit.

    Everything needed to set up both waterbutts and link together. These will be used to collect water running off the garden shed. As the taps can be connected to a hosepipe I will take advantage of a short piece of hose connected to the tap to fill up the watering cans to make life easier for me due to the location of the butts. Everything supplied is of good quality and I will definitely return to your company when my large and very old water butts need replacing.
