[C320-list] Hot Water Pressure at a trickle

[BA1978 at comcast.net]

Hi Christian,

I used a compressor for the first time this year.  I have some new valves and fittings back at the water pump to add an air hose just downstream from the pump.  Put a hose from that spigot to the bilge and that did a nice job except I know (pretty sure... ) that there are a couple of gallons left in there with that spigot way above the bottom of the tank (weird they do that... ).  That extra water in there has always diluted the antifreeze, but, maybe I'm wasting a bunch of money on antifreeze.... 

Very much appreciate your input!

Bill,
I'm in Chicago, so like you, in a hard freeze zone.  I've never put antifreeze in my plumbing lines, only bilge and head.  I use an air compressor to blow my lines out.  And on the hot water heater, I hook up a wet vac to the heater spigot and suck the water out of the heater.  Just did this on Sat, 8th year, never had an issue, where I've seen temps get below -20F for multiple days straight.
