Product details

The Polaris 9-100-1200 is the genuine in-line back-up valve for the Polaris 360 pressure side cleaner. It fits the larger corrugated hose the 360 uses, which measures roughly 1-1/2 in. in diameter.

What it does

The back-up valve cycles on a timer built into the valve itself. Every few minutes it redirects flow to a rear jet that pulls the cleaner backwards, breaking it free from steps, ladders and corners so it can carry on cleaning. When the valve wears, the cleaner either stays stuck or the valve sprays nonstop.

Check the hose first

This valve is made for the ribbed 1-1/2 in. hose. If your hose is smooth and about 3/4 in. across, you have a different cleaner and need the G52 back-up valve.

Before you order

It installs in-line in the feed hose. If the hose sections themselves are cracked or stiff, the complete 360 feed hose or the 6 ft 9-100-3102 replacement sections are the matching parts.

Questions and answers

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

What does the back-up valve do?
Every few minutes it diverts water flow to a jet that pulls the cleaner backwards for a short burst. That is what frees the cleaner when it wedges against a step, a ladder or a corner.
How do I know I need a new one?
Two signs: the cleaner gets stuck and never backs itself out, or the valve sprays continuously instead of cycling on and off.
Is this the right valve for my hose?
It fits the Polaris 360 corrugated hose, which measures about 1-1/2 in. across. If your hose is smooth and closer to 3/4 in., order the G52 back-up valve instead.
Is it a genuine Polaris part?
Yes. 9-100-1200 is the Polaris OEM part number for the 360 back-up valve.
