Polaris 380. Is the back up valve supposed to have a jet of water coming from it when it is not in 'back up mode'? I'm assuming a trickle is fine, but I'm getting a jet of water permanently from the valve. The jet is about 40 to 50% of the power of the jet that you see at 'back up cycle' time. I'm sure this is robbing the cleaner of power. Wheels are rotating at about 20 RPM.....not 28 as I read in the service book. Time for a new valve I think?
Thanks in advance
