This kit allows you to connect ordinary water butts to downpipes that are of a 50mm outside diameter. You can fit them to 19mm or 25mm internal diameter pipes.
Our 50mm downpipe kit is for use with downpipes with an OUTSIDE diameter of 50mm (such as the FloPlast Miniflo system commonly used on greenhouses and sheds).
The downpipe adapter is fitted inside the 50mm pipe.
This 50mm kit now has an additional part that adapts the standard 19mm spigot to a 25mm spigot.
This adaptor fits to FLO PLAST mini line 50mm downpipe.
This listing is for the adapter only. Tubing and downpipe is not included but can be purchase separately.

Couldn’t understand quite why it wouldn’t fit the downpipe until I realised that there were the remnants of a downpipe already in it. Extracted and fitted, now works fine. Looks like this had been used previously or was a return from a customer.
Thank you for taking the time to review the 50mm Downpipe adapter, the 50 mm adaper has a plasticspring inside the flexible part which pushes the adapter onto the internal faces of a 50mm downpipe to ensure there is a seal between the inside face of the downpipe and the adapter.
If you have fitted this adapter on the outside of the downpipe it is likely the downpipe it is fitted to is less than 50mm external diameter.
All our adapters are new we do not re sell used stock.
If you have any further enquires on this please do not hesitate to contact us.
Kind regards Sarah
It took quite a while to arrive. Before l just bought the adapter on its own but now you have to buy kit which l didn’t need and extra cost so not very happy.
Adapter was perfect for connecting from the drainpipe to the water butt. Only downside is that it is expensive for what you get to be honest, but saying that, it completed my project.
You can't seem to find a kit like this elsewhere but there are some problems with the design. Specifically I have used it to adapt my 25mm (ID) downpipes on my Robinsons greenhouse to a 50mm minipipe so I could fit a rainwater diverter (it's a big greenhouse!).
However the 25mm adaptor in the kit has a barb which makes the effective diameter ca 28mm, and the barb was not made of a solid plastic (not rubber) and so split my 25mm downpipe when I tried to fit it. Solution - I had to sand down the barb until it fit which was a bit of a pain - esp if you do not have a multitool.
Also the 50mm adaptor has a tendency to disappear down the pipe - a bigger lip would be good. Otherwise good.
Note to manufacturer use a soft rubber for the barb as downpipes are not thermoplastic.
