My pump would prime itself instantaneously before. But now it will take several seconds to prime (and each time I opened the air relief valve). This happens after I accidentally turned off the main pump while the booster was still on. I was meant to turn off the booster, and I immediately realized the mistake and turned the booster off. So, there were only several seconds that the booster was on while the main pump was off. Is it a coincidence or it actually does cause the delay in prime? Any suggestions on solving the prime issue? Thanks.
