20" Jumbo Melt Blown Cartridge 20m
This depth cartridge is designed for high flow situations, to remove quite large particles, rather than organic debris.
A good selection for farmers that draw their water from silt laden streams.
The next cartridge should be a 5 micron.
Being a 'depth cartridge' this is not cleanable. Plugging is evidenced visually - it darkens progressively from the inside outwards.
When fittings always relubricate the sump Oring and threads, to enable sealing from hand tightening the sump. This avoids flattening of the Oring due to 'overtight'.
Always purge before finishing your systems cartridge change, to avoid unnecessary air spurting through your household taps.
Sumps tighten from the effect of water pump pulsation.
