Product Detail

Our iron and manganese units include ABS lined cylinder, Automatic back wash valve. 1.5m drain hose.

Type: Iron and manganese reduction unit

This filter is designed to collect Iron and Manganese and Hydrogen Sulphide (the rotten egg smell) from the water during the day and automatically backwash at night to clean the Iron and Manganese it has collected during the day.  This filter is designed for properties that don't have cold water storage in the loft so the Iron will need to treat the water as it is required so if 2 baths are running at once the filter must be able to cope without causing a flow restriction.

This filter has a Potassium Permanganate backwash to help with the backwashing of the filter, rest assured the Potassium Permanganate is not used to treat the water it is only used to clean the media in the filter similar to putting rinse aid in the dishwasher.

The Iron and Manganese filter will also need a pressurised supply of water to backwash with so will need to be fitted after the pressure vessel although this filter wiil work in other applications but this will need to be specified when ordering.

It is always advisable to email a test report on your water before buying the filter to ensure the filter is right for your water or alternatively you could give us a call as the advice is free!

For use with potable water to reduce levels of Iron, Manganese and Hydrogen sulphide.

This is a filter for essentially low contamination levels with a flow rate of up to around 35 lpm depending on contamination levels.

The potassium Permanganate is a cleaning agent used to clean the media more thoroughly than using water alone the Potassium Permanganate will need recharging every 6 months.

Please Note: Potassium Permanganate is a controled substance and therefore we require you to fill out a declaration form and return it to us (by email or post) before we can dispatch your goods.

Installation Guide



  1. Unscrew control head from cylinder and remove gently
  2. Place riser tube back into cylinder ensuring it is central
  3. The media charges are numbered. Pour first bag of media (labelled ‘1’) into the cylinder ensuring none enters the riser tube and that the riser tube remains central. Use of a funnel is recommended
  4. Shake the cylinder gently to level the media
  5. Repeat steps 3 & 4 for each bag of media in numerical order
  6. Push top screen onto riser tube and replace the control head screwing up firmly
  7. If you have a potassium permanganate tank this should be ready charged (we recommend the level is checked on at least a yearly basis)


  1. Connect the inlet of the iron unit to the water supply,
    DO NOT connect outlet
  2. If your unit has a potassium permanganate backwash tank:
  • ·         Locate the ‘black tee’ on left side of unit head
  • ·         Partly unscrew black nut
  • ·         Push the black 3/8” tube from the tank, through the black nut and into the black tee
  • ·         Tighten nut to secure – do not over-tighten as this could split.
  1. Fit drain line to the drain elbow on top of head
  2. Allow water to flush through the unit slowly until water runs clear
  3. Connect outlet to water line
  4. Connect transformer to power supply.
  5. Press the scroll button on head ONCE and set the correct time using the up and down indicators
  6. Press the scroll button TWICE to initiate a manual backwash (total time 85 minutes). NB: Once backwash has started the whole cycle must be completed – DO NOT stop mid-cycle
  7. The system is now in service.

NB: If a PH correction unit is required this must be fitted on the water line BEFORE the iron & manganese unit.


  • Partly unscrew black nut at back of valve head on Iron & Manganese Unit
  • Push tube from potassium permanganate tank through nut in black elbow
  • Tighten nut to secure.  Do not over-tighten as this could split nut
  • Fit overflow pipe to elbow on side of tank and run to drain
