Product details
The Polaris 39-300 is the water management system assembly for the Polaris 3900 Sport and P39 Sport pressure side cleaners. It is the genuine OEM part and comes with its o-ring.
What it does
Pressurized water arrives at the cleaner from the booster pump, and the water management system is what decides where it goes. Drive, sweep hose and the vacuum action all depend on getting their share. When the assembly is worn or damaged, that balance is lost and the cleaner starts to behave oddly even though the booster pump is fine.
Fitting
It is supplied as a complete assembly, so there is nothing to build up from loose parts, and the fresh o-ring means the seal is new when it goes back in.
