Hi all,
We installed some condensate pumps in mini-split AC to drain the water upwards but something went wrong.
One of the pumps (they're 3) stopped working after a week or so, we thought it overheated and "burned", we changed the pump, and after that all pumps worked but after a whyle (after the AC unit had been shutdown) the AC indoor units would start to drip (we think the water in the pump pipes backtracked into the unit (note that the pumps have external power, always ON).
Since we had to move the pumps earlier (because of noise) we used a conection to "extend" the pipe that goes from the remote detection unit (level float) to the pump, that may be the reason why the water comes back (since the pipes should be always filled with water.
Any ideas about this, right now none of the pumps is working, we're gonna go there again and change one (trade it for a sauermann), change the pipes (no cuts or unions, full lenght pipe) and see how it goes for 1 or 2 weeks.
If anyone has any similar experience I would appreciate the help.
Have a nice day!
