Pentair Manifold Internals 400K | 77707-0209

Frequently asked questions

Will this cleaner work with my pool's plumbing?

Automatic cleaners are split by drive type - suction side, pressure side and robotic - and each needs different plumbing. Suction cleaners run off the skimmer or a dedicated line, pressure cleaners usually need a booster pump, and robotic units run on their own low-voltage supply.

What is the part number for this pool cleaner?

Pentair lists this pool cleaner under part number 77707-0209. Quote 77707-0209 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.

How long do the wear parts last?

Tyres, wear rings, diaphragms, flap valves and hoses are consumables and are replaced on a schedule rather than only on failure. A cleaner that slows, climbs poorly or stalls in corners is usually telling you a wear part is due, not that the unit has failed.

How do I confirm this fits my equipment?

Match the part number stamped on the component you are replacing, or look it up in the parts list for your Pentair equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.

Does this listing include hoses and accessories?

Check the specification section above. Cleaners are sold both as complete units and as heads without hose sets, and hose sections, leaders and swivels are also sold individually as replacements.

Is there a warranty on this pool cleaner?

It carries the standard Pentair manufacturer warranty. The terms are set by Pentair, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
