Tank & Filter Maintenance Tips

Cleaning Your Filter

It is recommended that your RainWatch Filter is cleaned every 3-6 months and often the Rainwatch Filter can be washed clean with a garden hose by lifting the filter membrane out (but not completely out of the RainWatch canister) and hosing it down. The cloth can be replaced every three years depending on the volume and frequency of Rainfall in your area and the level of exposure to contaminants.

The inside of the canister of the RainWatch Filter enables you to easily identify how dirty it is.

If it is time for a clean,

  • Drain the RainWatch Filer by removing the two black cleaning caps.
  • Then open the top of the canister by removing the 8 clips.
  • Remove the filter plate using two screwdrivers as shown in our maintenance guide (Fig 2) by gently lifting the filter plate out of the RainWatch canister.
  • Rinse your filtration membrane in clean water.

When complete, simply reassemble the RainWatch Filter making sure the canisters O ring is also clean.

If a rinse is insufficient, the RainWatch filter cloth is NOT machine washable and (cold and only cold water only) with thorough hand washing probably up to ten times.

Tank maintenance

It is recommended that in order to keep a quality rainwater catchment, that you visually inspect your rainwater tank and surrounding catchment components (gutter roof water tank and pipework) every 6 months and de sludge your tank every 2-3 years.

With RainWatch as a pre-filter, the extraction of contaminants before the storage of rainwater results in a significant reduction of sediment build up in the rainwater tank. This means an exponential decrease in the amount of sludge that needs to be removed.

We estimate that with the addition of the RainWatch Filter, the cleaning period and de-sludging can be extended to once every 5-10 years (depending on how well other components are maintained, and exposure to other contaminants).
