My float valve in my waste tank didn't work on a job this morning? I think it needs adjustment but not sure. Water was coming out my vacuum exhaust. It was spraying out pretty good. I drained the tank and ran the machine for a while. I then sprayed wd-40 in the lubrication port to dry up any water that was in there. Should I do anything else? Maybe change the oil in the blower? Thanks for any info in advance.
