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.

Q: What is the decibels dab at one meter from the 90,000btu salt pool heat pump.? What type of metal do you use exposed to salt pool water. Dave

A:

Hi, we do not sell a cover for our heat pumps. They are designed to be outside through the winter, but if you want a cover they are available through aftermarket sellers. We do not have a recommendation on one. We find that putting a cover on them creates...
