Thanks Peter,
how did your pump fare from it having to get the water through a smaller bore pipe & did you have any issues in winter with the pipe freezing due to the thinner walls of the Aqua-dapter hose?
I've had no problems with the pump, in fact i've hardly upped it at all (I use a pure freedom trolley as a van mount).
In the winter, I bring the hose reel inside (it's so light to carry) and yes it can freeze a bit but then I probably won't be cleaning anyway if it's that cold. Also because it's so thin it defrosts very quick if you stick a fan heater next to it.
When I first started using it, I just bought 50m and attached it to my existing 8mm mini bore, in case I didn't like it and I could just remove it.
