Pentair 155226-43 Cartridge Filter 25 Micron 20 Inch Polypropylene

Product Description

The PENTAIR 155226-43 is a spun bonded polypropylene cartridge filter designed to remove sediment from residential and light commercial water supply lines. Measuring 20 inches in length with a 2.375-inch outside diameter, it fits standard 20-inch filter housings and delivers 25-micron mechanical filtration. The polypropylene construction handles operating temperatures from 40 degrees F to 145 degrees F, making it suitable for cold and warm water applications. Plumbers and water treatment technicians install this cartridge as part of whole-house filtration systems, under-sink assemblies, and point-of-entry setups where sediment control is the primary concern.

This filter is used in residential and light commercial potable water systems to reduce sediment such as dirt, rust, and fine particulate from the water supply. It is suited for installation upstream of water heaters, softeners, and other treatment equipment to protect downstream components from particulate fouling. The 25-micron rating makes it appropriate for general sediment pre-filtration rather than fine polishing applications.

Installation Notes

A licensed plumber or qualified water treatment technician should install or replace this cartridge. Shut off the water supply and depressurize the housing before removing the filter cap or cartridge. Follow local plumbing codes and the housing manufacturer instructions for proper cartridge seating and cap torque. Replace the cartridge when pressure drop across the housing increases noticeably or on a scheduled maintenance interval.
