Three weeks ago my VG4 pump started cycling for about 15 seconds throughout the night. “Time to perform maintenance,” I cheerfully thought. Somehow, after three complete tear downs, two maintenance kits, 2 bellows, one new pressure switch, and one set of new o-rings, I have gotten the system worse— is the pump cycles for 3-5 seconds every 2 minutes.
Is this acceptable or a harbinger of impending disaster? I was ridiculously careful during the last rebuild, almost operating in clean-room conditions. Is it possible that the seal between the top of the accumulator tank and the base goes bad? I even disconnected the input side of the accumulator and sealed it with my hand—same exact 2 minute cycling.
What is the acceptable hold time for the vacuum?
Thanks,
