Two fresh water drains?

[ctpres]

Our 3211 has low point drains for hot, cold lines and fresh water tank on drivers side of wet bay.
On passenger side there is another fresh water connection near bottom of tank and cutoff valve with about two feet of hose laying in bottom of the bay. What is it for?

Are you sure it connects into the bottom of the fresh water tank? It sounds like your winterizing hose - if it is, then there should be another shutoff valve on the main water line upstream of where the stub hose tees into it. To winterize, you close off the main water line, stick your stub hose into a jug of RV antifreeze, open the valve on the stub hose, start your water pump and run antifreeze through your fresh water system.

it is a tank drain and winterizing hose Just put your HW heater on by pass close valve to tank open drain valve and put hose in rv aniti frezze turn on the water pump.
When sanitizing the tank the 2nd drain helps takes a while to drain

Well I'll be dxxxx. Never would have figured that out. Big Texas Thank You. With a little luck I'll never use it.

gasser 38 is right. Here is mine where I marked the hoses/valves.

shellback1 - Yup that is exactly what it looks like. Ours almost two years old and I am still learning about the various systems.

As I stated, to winterize the unit with the piping shown, close the top valve, open the bottom valve with the hose inserted in a jug of RV antifreeze, turn on the water pump and (with the water heater tank bypassed and drained) start at the farthest point from the water pump and open the valve/fixture until you have a flow of RV antifreeze and work your way toward the pump repeating the procedure. Be sure that drain P-traps are protected with the RV antifreeze as well.

Maybe I need to start a new thread, but I'll try here first, since this is where the idea came from and is most applicable to similar Damon products.
Now that I have a better understanding on the plumbing why couldn't I:
1. Add surge tank in this bay, tapping into the line feeding the pump?
2. Relocate pump to this bay. Easier to service and silence the pump, also would free up more useable storage space in bath cabinet.
This is the smallest basement bay and I would not miss the space. Also this bay is heated so little to worry about in freezing weather. In both cases my plumbing add-ons would not present any possible water damage in living space.

Don't see why you can't.
