I have a 1 year old JB Platinum pump that has worked great until yesterday (when I went to start up a heat pump 50 miles away) Anyway, It fell over in the back of the van for the first time ever and when I got to the job I changed the oil, filled it to the fill line and started pumping away. I let it do its thing for 15 minutes and came back to check the reading, 7000 microns... The pump wasn't making its normal gurgle so I checked the sight glass and found that the oil level was pegged completely above the glass. I turned it off and the oil went right back down to the fill line. I drained a bit of oil out and tried again to no avail. Do you guys have any idea whats going on here? I plan on having it sent back to JB to fix it but I want to make sure there's not something that I'm missing here.
