    i have a high efficiency ac system. Condensate drains down to a pump and is pumped out. The pipe from the ac unit to the pump is now backing up. There is a cleanout into which I have inserted a tube to siphon the water out.But how to clean this line out to fix it?

    Connect a shop vac to the line, that should clear it.
