I have a dual chamber CR 140 for about a year and a half and my old OTP-2000 was loud so I just ordered a new one got it installed last night and let it run full open (no CO2) to get the air out all night and there is still air bubbles trapped inside and seems to be louder than previous pump (feeling like its a me issue and I wasted money on a new pump) but how do i get all of the air out and get this thing quiet???
