Connectors ideal.

This little fitting sorted out my water butt problem and saved me a lot of extra work and time.

The downpipe adapter is something I've been looking for, for years. It fitted perfectly with no problems and diverts the water to the butt without any leakage. Fast delivery after ordering too. Thanks very much....highly recommended

Downpipe adapter for water butt

Very happy with the adapter that worked as we wanted

Fantastic piece of kit for my greenhouse!

I was bought a water butt for my Halls greenhouse . Sadly the 2 did not have compatible accessories , nor could I seem to find any that were. That was until stumbling via google across this adapter from Rainwater Terrace . The communication was excellent via email . Peter was extremely helpful , and the item was delivered really quickly.
It fits perfectly, with the additional piece of tube that was kindly sent . I would recommend this as well as the company - fantastic !
