How Does a Mini Split Drain

Mini splits need to connect a drain pipe at the indoor unit to discharge the condensate water to the nearest plumbing pipe. Mini splits use a drain pipe to drain condensate water via gravity flow. A drain pump can be used to assist the drain of the condensate water.

How do mini split systems drain?

It drains water just like any other mini split. Typically you will have an air handler on the wall and there will be a condensate hose in the air handler. You have to drill a hole in the wall and you put that condensate drain out through that hose. You run it down through the house and it drains out.

Does a mini split need a condensate pump?

Many mini-split systems are not equipped with a condensate pan because the water is drained with the help of gravity. However, there are situations where gravity draining is not an option. When this is the case, a condensate pump is needed.
