WSI-PTC-45-2001 Jumbo 20" Pleated Cartridge 1m
A high flow final filter cartridge in a filtration system designed for typical water quality, that contains a normal amount of debris, evidenced by plugging at 6 to 9 months.
Used as an alternative to a 1 micron depth cartridge to allow periodic cleaning.
Premature Plugging can occur during 'high pollen'. The pollen clogs the papers pores but is difficult to see. The paper otherwise looks clean enough...
Can be washed.
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.
