Of late, our water tanks of which we have two (4500Lt & 2200Lt), have been getting full of sludge and sediment and this has been flowing through into the outdoor taps and also the cisterns that we operate off them.
1. Has anyone any ideas on how this can be remedied?
2. Are there companies that can clean them for you?
3. Do you need to first empty the tanks or can they do it by filtering the water back in?
4. Are there chemicals you can add to prevent the build-up?
Thanks
