One of the tasks that happens on a yearly basis is the cleaning of the water system. This involves filling the tank with a solution of PuraClean, running it through the taps then leaving it for a while. Usually about six hours or so. Then, drain the system down and fill with clean water and flush through.
I don’t drink out of the water system, this isn’t recommended but this year I’m hoping to get to some more out of the way sites and some of them don’t have toilet blocks so a functioning and reasonably clean water system is essential.
The water system itself is interesting. It works by being having a pump keep the system under pressure. When a tap is turned on, the pressure drops and the pump starts working.
