Excellent customer service

I bought the adapter for my greenhouse downpipe, but needed an additional section to make it fit. Very helpful advice on the phone, and the additional piece worked first time. Thanks!

Greenhouse Water

After a lot of online research I did not think at one point that I could find these adapters for my greenhouse downpipes to feed water butts but am very pleased with the outcome. They worked absolutely fine and were simple to connect. Well done Rainwater Terrace for thinking of this idea. I have put your site in my favourites in case there is some other gem you might have.

Water butt connection

I needed to connect my water butt to the 40mm downpipe on my green house. This adapter worked perfectly and my butt is now filling up nicely. The person I spoke to on the phone was very helpful and the adapter arrived very quickly.

Just what we needed!

Having realised that the water butt we bought from a different company didn’t have the right attachment for our pipes we found this adapter. Did the job perfectly. Very easy transaction.
