Product details

The Pentair 170040 is the genuine OEM bottom manifold for the Clean and Clear Plus cartridge filter, for units built after December 2000. It sits in the base of the tank and carries the lower end of each filter cartridge.

What it does

A cartridge filter only works if every drop of water is forced through the media. The manifolds are what make that happen: the bottom manifold locates and seals the lower end of each cartridge, and the top manifold does the same at the other end. Between them the cartridges are held square, on center, and sealed against bypass.

When it needs replacing

Cracked ports, a split body, or a manifold that no longer holds cartridges upright all mean the same thing in practice. Water finds the gap and skips the media, so the pool stays cloudy while the cartridges look perfectly clean. If you have cleaned or replaced the cartridges and the water still is not clearing, open the tank and look at the manifolds.

Before you order

Confirm the production date of your filter. This manifold is the version Pentair specifies for units after December 2000. The top manifold and the air bleed tube assembly are separate parts.

Questions and answers

What people ask about this product, answered by our pool techs.

Will it fit my Clean and Clear Plus?
It is specified for units built after December 2000. Filters made before that date use a different bottom manifold, so check the date on your tank before ordering.
What does the bottom manifold do?
It sits in the base of the tank and holds the lower end of each cartridge, keeping them square, on center and sealed so water has to pass through the media.
What happens if it is cracked?
Water takes the easy path. Instead of passing through the cartridge media it slips past a broken port, which means dirt goes straight back to the pool no matter how clean the cartridges are.
Do I need the top manifold as well?
Not automatically. The top manifold and the air bleed tube assembly are separate parts. Inspect both while the tank is open and replace whichever is damaged.
