Quick overview

  • Genuine Polaris part 9-100-1204 The OEM back-up valve mechanism for the 360 cleaner.
  • Goes inside valve 9-100-1200 This is the internal mechanism, not the complete in-line back-up valve.
  • Restores the reverse cycle The back-up valve is what periodically sends the cleaner backward so it can free itself from a corner or a step.
  • For the Polaris 360 Listed with the Polaris 360 pool cleaner parts.
  • Cheaper than the whole valve If the housing is sound, replacing the mechanism brings the valve back without buying the assembly.
  • A known wear point The mechanism cycles every few minutes the cleaner runs, so it wears long before the body does.

Product details

The Polaris 9-100-1204 is the genuine OEM mechanism for the in-line back-up valve used on the Polaris 360 pressure side cleaner. It is the working internal part that fits inside back-up valve 9-100-1200.

What the back-up valve does

A 360 cleans by wandering the pool on a random pattern, and the thing that keeps it from getting stuck is the back-up valve. At intervals the valve diverts water and the cleaner reverses for a short run, which is enough to pull it out of a corner, off a step or away from a ladder. When the valve stops cycling, the cleaner parks itself and stays there.

Mechanism, not the whole valve

This listing is the mechanism only. It is the part that actually cycles, and it wears long before the housing does, so a valve with a good body can usually be brought back with the mechanism alone. If the body is cracked or the hose barbs are damaged, you want the complete valve instead.

Questions and answers

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

Is this the complete back-up valve?
No. It is the mechanism that goes inside the Polaris 360 back-up valve 9-100-1200. If the valve body itself is cracked, you need the complete valve instead.
Which cleaner is it for?
The Polaris 360. It is listed with the Polaris 360 pool cleaner parts.
What does the back-up valve do?
It interrupts normal operation at intervals and drives the cleaner in reverse for a short run, which is how the 360 gets itself out of corners, steps and behind ladders.
How do I know the mechanism has failed?
The usual signs are a cleaner that never backs up, or one that stalls in the back-up cycle and stays there. Both point at the mechanism rather than the hose.
