Been on this and Matt's site for about three months vacillating between different options. This trailer is not braked, it does have a jockey wheel, and I have sent away for some prop stands (legs) to stop it tipping back.400l is 400kg and I am hoping that I can manage it, and do not end up chasing it down a hill
In the end it was a bit much for me to decide, as I am not good at DIY, and do not understand everything about pure water.So phoned a supplier up who Matt recommended and let him tell me what I wanted and it was delivered the next day.The 400l tank fitted snugly with packing wood either side and a two by two bolted through the floor with five bolts to stop it coming back to where the pump box, leisure battery (Free), and DI sit. Also supplied was 100m of mini bore and reel, Unger tele pole plus with vikan, and a 3 by 3 for downstairs.
My RO which came at the same time only registered 3.5psi and trickled out, and I had to phone up for a booster pump which was sent the same day and was easy to fit. Now it's a gusher 15psi, 278ppm in, 0-1ppm out.
