Most of the manufacturers of irrigation equipment are based outside of the UK. This is true of our two key brands; Rain Bird is American and Antelco Australian. It means the videos they produce are biased towards their home bases and use a few terms we are not familar with. However, there is still a lot of valuable content - these are some of the best.
We have focussed Rain Bird on Sprinkler Irrigation and Antelco on Drip.
