At the beginning of the season one of our 2 washers went down (both running cat pumps) i replaced one with a different brand and its been great! Our second washer is fairly new with only 1 season on it. Everything was working fine yesterday, took the rig out this morning and the cat pump isnt producing any pressure. Water flow was good and constant but no pressure through the pump. Its pretty cold here in NY so ive been parking the rig in a heated garage. Checked oil and everything looks normal. Any ideas?
