I have a 10 year old polaris 65 and it needs a new float hose. I have only had this machine for a year it came with the pool. I would like to keep it going but I'm concerned that the internal workings could be getting old. It operates Ok sorta does lazey 8's in the pool. It could be that the old hose is less pliable (SP?) . Could some one tell me which parts to inspect for wear so I can decide if I want ro rebuild or replace the whole unit. I recieved the origonal manual with the polaris and Part #34 Polaris 65 Filter Screen was not included when this machine was manufactured.

thanks again
