Product details

Pentair part 178578 is the replacement tank bottom assembly for the Clean & Clear Plus cartridge filter and the Quad DE filter. It fits filters manufactured after 11-98 and is the genuine Pentair part, so it seals to the existing lid and clamp the way the original did.

When you need it

The lower tank takes the load of the plumbing and the pressure of the system. When it cracks, weeps at a port or has been damaged by a freeze, the rest of the filter is usually still good. Replacing the tank bottom keeps the lid, clamp, cartridges or grids and internals in service.

Before you order

Check the manufacture date on your tank label. This bottom is for filters built after November 1998. The tank o-ring and clamp kit are sold separately, and a new o-ring is the right call any time the tank is split and reassembled.

Questions and answers

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

Will it fit my Clean & Clear Plus?
If the filter was manufactured after 11-98, yes. Check the manufacture date on the tank label; earlier tanks used a different bottom.
Does it fit the Quad DE as well?
Yes. The Clean & Clear Plus and the Quad DE share this tank bottom for filters built after 11-98.
Does it include the o-ring and clamp?
The tank o-ring and clamp kit are separate Pentair parts. Plan on a new o-ring whenever the tank is opened and reassembled.
Why replace the tank bottom instead of the whole filter?
Because everything else on the filter is usually fine. The cartridges or grids, lid, clamp and internals carry over, and a new tank bottom costs a fraction of a complete filter.
