Bought two 10m hoses today (Ekka holiday) from Bunnings and fiddled with them to get them to work. It does, but I have to secure the coupling from the machine's hose or there is yet another flood inside.
Otherwise, it seems to work but I need another 10m hose, to reach other parts of the garden, at the R Rd end. I will get that on the weekend, when I will have to do more laundry.
Bought the extra 20m hose on the weekend, and connected it. Worked well. Hopefully it makes a difference to my plants.
