This is the main water tank for the farm troughs, gardens, trees etc. It holds 15,000 litres when full but when a horse or cow trips over a pipe it tends to hold zero water fairly quickly. After finding an empty tank last night it was time to fix the problem.
I needed a system to keep the tank usable, but limit the loss of water when the inevitable happens. Until all the fencing is finished, there will always be temporary plastic troughs floating around and they are easy to trip over or disconnect.
My trusty cordless drill made short work of the plastic tank side – drilling a hole half way up.
Here’s the tank fitting in the hole. Rubber gaskets seal it from both sides between the two halves. Thankfully, what you can’t see is me having to climb into the tank in my boxers to push the fitting through from the inside. Luckily the water was only knee-deep (thanks to the horses).
The finished job – you can see we now have two exits for water, both with valves. If the bottom valve is shut then water can only drain as far as the halfway point before running dry, but we still have half a tank safe in reserve for when the problem is fixed (and a few days of water in which to refill).
