Is there a way to calibrate the 1 oz Carlisle Coldmaster pump? I have several of these pumps, but two are pumping more than 1 oz. One is pumping 1 3/8 oz and the other is pumping 1 1/4 oz. I am using them for flavored syrups on soft drinks that require precisely 1 oz of syrup.
This can be used with an insert, that is sold separately, to confirm you are dispensing the exact amount. This can dispense either 1/2 oz or 1 oz.
