Water Pump

[Digger]

Just had a thought last year I had to replace the pump for the water tank because there was water in it and it was this time of year so it froze up and split, a new one is not cheap so it might be a good idea to check that there is no water in it.

I have a good habit to empty the tank before driving back from a holiday, otherwise the weight slows it down & increases petrol consumption.
The only time it gets filled is when on site, i never use it for drinking water though, i keep a separate water container for that
