I have a issue with condensate pump on a Mini Split I installed. want to know if others have run inot the same issue and how they fixed the problem. <br><br>This is a NEW installation of Mini split and pump : Purchased 4 Sauermann si-30 condensate pumps all have failed after 3-4 days of use. Purchased new design of si-20 multi positional pump also with the same result. The pumps burn up. This is a 2 ton mini split. system with the length of the drain tubing is 15 feet. Has a 2 foot rise over the 15 feet. Everything works good for a few days then pump seems to burn up. Again this happen 5 times in a row. I can blow the water out to the drain tube easily with my mouth. the drain tube drain end is cut 1 foot fall so there is no suction that i am aware of. Home owner uses it for a few hours at night to then turns the ac off Home owner now cuts the circuit breaker off at end of each night use to prolong the pump life. <br> Any help would be appreciated!
