Rainwater Saving Diverter Kit. On-Off Lever. Fits Round 68mm & Square 65mm With Auto Overflow. Black. Comes with complete fitting instructions.

This product has been doing its job perfectly from day one, been able to fill my water butt and prevent over fill , great easy design, and easy to fit and use

Easy to install, but more importantly, the diverter is sturdy and well-designed. Pleasing to discover that there is a control lever on both sides.Perfect for harvesting rainwater to keep the wildlife pond topped-up

Works well but leaks round the top if high flow rates & you have a round downpipe. It’s easily fixed with a strong sealant in the 4 corners before you push the top converter down. It’s looks like it would be fine with square pipe. The diverter manual switch is positive; whole thing well constructed.I’m using it to collect rainwater & bath water in the same butt & one can select the bath water to go straight to drain with this switch. They run down the same downpipe like a lot of old houses. The pipework all fits UK standard butts and downpipes.

It's manual system so you have to re bet to swap it over when tank is getting low , BUT it doesn't block like auto systems and is easier to control.

Easy to fit and works brilliantly. Completely filled the water butt in one shower of rain. Easy to turn on and off too. Will be buying another.

Fantastic bit of kit better than all the rest on the market, would recommend to anyone who is collecting rain water for carnivorous plants.

This is a very well-made product with excellent instructions.It worked very well this morning with the welcome arrival of a heavy storm. Would recommend.

Item was received a few days before delivery date. It was installed the same day, quite easily and works well as far as I can see. I did have to put a filter at the top of the drain pipe as debris seem to be clogging it when the flap is closed. My only personal issue is that mine is installed on a flat roof, so when my tanks are full, I have to climb a ladder to open the flap. So some sort of automated system would be more useful.Other comments regarding the flap not sealing effectively is kinda a mute point and does not need to seal shut, as when it rains, it’s impossible to get such a large quantity of water to funnel into the 20mm pipe feeding the tank. So a certain amount of overspill depending on the rainfall intensity is inevitable.
