Pentair may be known as the brand that redefined the industry with its smart, sustainable solutions for pool and spas, water supply and disposal, but its 4000 Series Filters are still a major breakthrough of the brand for solving major pool consumers' pain points.

What people can expect from the 4000 SERIES FILTERS' technology include: sheet molded fiberglass tank with PPO resin backwash valves for long life, dependable performance and easy maintenance; a filter with refined internal design that minimizes flow restrictions requiring the least amount of pumping power; and ability to produce the maximum required flow rates – for lower utility costs.

Regardless of the promises offered by Pentair as a brand, standard wear and tear issues may soon render these filters unusable. You can prevent that by considering the repair parts you can find in this category as the genuine replacements you will need to get them right back up running again.

The first component in this category you may soon need replacing is the: 074922 PENTAIR ELEMENT, (4024 12" 8 REQUIRED). With this component, you can expect the 4000 filter to deliver a Maximum Operating Pressure of about 50 psi with corrosion-resistance of about 20 in. in diameter with fiberglass filter tank for strength and durability.

The next item you may need to replace is the 075207 PENTAIR DRAIN COCK, 1/4" NPT. This filter element is what helps the filter to continue offering the Unique Spiro-Mite grid design that provides high efficiency filtration and longer filter cycles.

The 071404 PENTAIR NUT (WING) is available in this category, too. We placed this here because this is a key component for your the Pentair 4000 Series to maximize its exclusive clamp ring design that's proven to be strong and reliable for quick and easy access to internal components.
