a pressure vessel and the water then passes though this. The vessel has an
automatic timer fitted that backwashes (passes water in reverse) the vessel at
set times, usually at night when you are not using the water.

material from the pressure vessel.

medium to make sure the pH is correct for the manganese dioxide base to work.
These two mediums are kept in the one tank and because of the mix we can use a
smaller tank then previously used before. After the pressure vessel we fit a
sediment filter to catch any particles that might get though. This is our
standard 10" filter housing with a 5 or 20 micron sediment filter fitted.
