I plan to install in a cottage in very cold climate that will require the unit to be drained every year. Can it be installed upside down to drain?

Not sure if can be upside down. Based on the way the connections are you can remove in Minutes and drain lines. or perhaps install a drain valve below.

Does this unit have a light to indicate it is working properly?

There are 2 lights on the ballast. A red one that shows power on and a green one that indicates the condition of the lamp.

My water pressure is 80 psi, and I get 1.2 gpm on my sink, will the water pressure change significantly?

Maximum operating pressure 125 PSI (862 kPa),Minimum operating pressure 4 PSI (27.5 kPa),I don't think it will influence your water pressure significantly

What size thread are the fittings?

The 6 GPM model is 1/2". The 12 GPM model is 3/4". I think that accounts for the different answers.
