Every mini split indoor unit creates water - it's a natural by-product of the air conditioning process.
Depending on where your mini split is placed, there may be no easy gravity-based way to drain the water outside. This condensate pump is specifically designed for mini splits with this issue.
How it works: Once this pump is installed, the residual water drains into it. After reaching a certain threshold in the tank, the water is pumped out to wherever the hose drains out and your mini split continues working at it's maximum capacity
