Help! Condensate pump is so loud and working when minisplit is off
I can see the pump turning on a couple of times after being in cooling mode but it should not have a lot of water to pump once the unit warms up.
if the pump is pushing water I would be concerned about the amount of ice in the head.
Is the filter being cleaned low air flow can cause icing.
Don’t run the ac when the outside temps are below 65F this can cause icing.
If there is ice on the evaporator coil it may take several hours to melt and your pump is doing it’s job.
I would be concerned about that much ice, floats usually stick closed and won’t turn off or fail to close and turn the pump on.
I have not seen a float cycle unless it has to lift the water and then a long horizontal run. What happens in some cases the water is syphoned back into the pump.
A simple check valve close to the pump is needed in this case this theory is easy to check by watching the water level in the pump tray.
