2017 WRX Air Lift 3P Viair 444c Check Valve & Pump Issue

One morning when I aired up to leave the house my Air Lift controller went black. Upon inspection, I found that one of my two 30A fuses had blown (two fuses for dual compressors). I found that I had a bad check valve on one of the units and I believe the other had started wearing out do to compensation for the leaking pump. I currently have a rebuild kit coming in the mail since after replacing the check valve the fuse was still blowing. Viair and Air Lift both confirmed that the issue is related to the 2.5+ year old pump. I had been chasong around a ghost leak and was glad to figure out that it was the check valve causing the trouble. I hope this helps and for the meantime I am running a 40A fuse in place of the 30A which is a common size that people use from the start.
