I have installed some extra water butts that were around the garden not being used and have connected them up together. I use these for reserve when my main tank runs dry. This has only happened once so far. My main tank is full again now.
I have moved the connections and the pump away from the electrics and into the corner of the garage and have finished insulating the pipes.
My meter has almost reached 5000 liters. That equates to around £21.00. I still need to do final calculations and also monitor how much electricity the pump uses to work out what I am saving.
I have also swapped out the timer for a digital one as the manual one broke down. I know run the pump twice a day for a 5 minute period. Within this 5 minute period the pump will switch off when it is full.
