Q: My heat pump is shooting water up in the sky. It looks like a place in the pipe has malfunctioned and the installers did not put a bypass in so I can't even run my filter. The model number is HP21004T. I tried calling your number but it seems like you don't turn the phone on even during normal business hours.
