That you can't use it!
Just bought this unit, looks and sounds great but you can't buy the pipe or fittings to go with it in the uk so a compleate waist of money!

This is a very good product. Performs perfectly. I am very satisfied with the performance. I have gotten inquiries from both friends and family. I highly recommend it to anyone who is thinking of rain harvesting.

I wrote this in the Leaf Eater comments and it deserves to be here too. I love these and combined them with the Downpipe First Flush Water Diverter Kit system. (also on Amazon) And they work great. I'm in a 3rd world Caribbean country and have had NO city water for almost 2 years and in a major drought. We are having are second heavy rain since last FEB. and watching these simple systems collecting water off a rather dirty roof with the Leaf Eater taking out the larger debris while the flush system takes captures the finer dust and... bird stuff. Both need a little cleaning type maintenance after a hard rain, it is easy to do and I'm glad to do it. I have 3 of the 4 Leaf Eaters installed so they are easy to get to from upper porch, the other I need a ladder. The Flush system needs to be opened at the bottom, easy by hand, to clear the drain. But since we have only had 2 heavy rains, they have a lot of garbage to deal with. Since we need all the water we can get, small price to pay. 1" of rain = 2,000 gallons for us going into 2 water cisterns. I'll take all that I can. Not difficult to install. We are on the Atlantic Ocean with VERY salty air; the Leaf Eater stainless steel grid has held up very well with NO corrosion at all. We also have had to put in a well, very salty and nasty water but we have filters/UV and 3 RO systems by iSpring that deliver 1,500 a day. When you don't have ANY water, you do what you need to do. When you find good products that could help others dealing with drought and water problems, then you should talk about them. Thank you

This item works very good with just one complaint: It has a very small screen (about the thickness of a highlighter) to filter the water before it leaves your pipe. This screen gets completely filled with brown scummy slime that blocks the screen up and water does not flow out the bottom. I even bought the Rain Harvesting Pty Ltd WDAC02 First Flush Water Diverter to help block larger amounts of junk coming off the roof but this did not help. I have come to the conclusion that you just need the First Flush Water Diverter in place and just remove that small screen completely. This allow water to flow freely out the small end of your pipe. Other wise this system works great! I highly recommend it after trying some of their earlier versions. (Their "Clean Rain Advanced" breaks very easily) You do need the Rain Harvesting Pty Ltd RHAD99 Leaf Eater Advanced Rain Head to make this item work though.
