Doesn leaf debris or sediment get into the stored water?
As small amount, yes. Most tanks accumulate a millimetre or two a year, but there are 3 further devices in our kits which ensure clean rainwater in the home. a) The calmed inlet prevents arriving water from disturbing and silt. b) The siphon on the overflow sucks dirt of the surface of the water c) The floating intake takes rainwater for the house from just below the surface of the water, where it’s clean.
