I was really pleased about the forum suggestion for watering cans. So after 5 journeys (2 cans each track to the tap), the 4 overflow pipes leaked water out. Yea, full, (I thought)!
Suddenly there was a flood under the van, water gushing out!!!
Split tank I thought as there was so much water.
After 2 more attempts at filling the tank with the cans I realised what was happening. This is after being drenched looking for a split under the van, guess what I found?!!!!
The 4, yes 4 overflow pipes were obviously far too deep into the water tank and all the water syphoned out and drained the tank!
