    Question Condensate pump for 7.5 ton

    Has anyone used a condensate pump for a commercial split system? Unit is 7.5 tons and there is no where to run PVC drain lines. Only solution is to go to roof 20' high.

    I have used pumps plenty of times, but a 20' lift is going to be expensive. I would see if I could tie it into a sink drain in a janitors closet. You may have to check you local codes.
    I STARTED WITH NOTHING, AND I STILL HAVE MOST OF IT!

    No sink or janitors closet nearby. Only option is pump up to roof.

    Than you have to find a place. 20ft head is rough and not a good idea. i can envision the problems.

    There is no place nearby and unit is installed in center of warehouse. There is no sewer or drain in building due to its just a parts storage. GC wants to pump condensate up to roof.

    I use it for washer machines slop sinks etc only problem it needs to be vented you can run the vent up to the roof with the drain or considering its not connected to a sewer you could get away with going out the side wall of the building it has plenty of head for what u need

    20' isnt that high, you could run copper and it would work fine.
