Question Winterizing 177

Hi there

I was working on winterizing my 177 today and could not find the pump and the bypass valves. Can anyone tell me where they are and how I can access them? The generic FR owner's manual was no help with this issue.

The pump should be within a couple of feet of the water tank. Turn it on, open a faucet, and listen for it! Between the pump and the fresh water tank, look for a two-position valve, with a 24"+/- piece of rubber hose attached. This is where you add anti=freeze (after switching the valve from FW tank to rubber tube suction).

Before doing that, look behind the water heater for three valves. The top and bottom ones you should close, and open the middle one. This isolates the water heater. Don't forget to DRAIN the water heater, or you'll freeze and crack it.

I drain and blow my system COMPLETELY clear of water with compressed air, then I pump anti-freeze in. That ensures that there are no low-sitting pockets of water.

My father has an 171 and both his hot water bypass and pump are located under the bed on the kitchen side.
