I would think putting water in the tank would only cause water to be drawn into the system instead of air, diluting the antifreeze if indeed the air was coming from the water tank. The best way to eliminate the tank is to bypass it with a valve as shown in the picture.

After reading Crabman's post above, I went out and tried adding antifreeze. The pump pulls with the fresh tank empty. I must have not had a good, tight hose connection when I previously tried with empty tank.

Sorry,
Mike

Looks like you`re a pro at this now Mike! Trial and error and asking questions is how we all learned this stuff.

I had similar issues on my Melbourne not sucking up the antifreeze. I bought a small winterizing hand pump from Camping World for less then $10 and it works like a charm. Once all the lines are blown out, just pump the coolaid through the lines. Helps to have a 2nd person to assist. In truth, if all the water is blown out of the lines, using antifreeze is really just an extra precaution. But I'm generally exta-cautious, so there you go.

Have done our 29D twice since winter. Had an issue first time but found I did not have the line to the fitting tight at the fresh water inlet.
On the first try also forgot to close the by-pass vales on the hot water heater tank.
A learning process.

I am a new owner of a Greyhawk (2010 31FK), and from reading the comments on this thread, there are NO other valves that need to be controlled except for those on the utility panel...is that correct??? That is everything (winterizing, sanitizing, fill, normal) is done from these two three-position valves.

I posted a question in the general chat area about not being able to get water to pump from the tank. Everything works OK in city fixture mode, but when I go to normal I have no luck. Most of the advice so far has been to find another valve like TTs have. But I haven't been able to find one. If there is one, it seems to be behind a panel under the bathroom vanity.

Ran out of time tonight. I am going to try and experiment tomorrow with a jug of water outside and the panel set for winterize lines. From the schematic of the hoses and valves I do see, that should be water to the faucets via the pump.

Any advice is appreciated from other Greyhawk owners. God knows the dealer hasn't been able to provide any. They told me you need to open/close the valves and the manual should tell me what to do.

NoRegrets,

On mine. Once I have water in the fresh water tank using "City Fill (1&6)", I set the valves to "Normal (3&5)", turn water pump on, open a water faucet, the pump starts and water flows in a few seconds.

Thanks Mike for the confirmation. With that information, and from everything I have read in the manual and looked over (and double looked over) in the MH, it sounds like there are no additional valves to control.

I tried my experiment of putting the panel in sanitize/winterize lines (2&4) with a jug of water outside to suck from with no luck. It looks like my pump might be bad. It runs, but never generates any suction.

Any experiences on how the pumps usually fail? I assumed it would be in the motor, and not the pump part...but mine is indicating otherwise.

I would be very careful in blowing out my lines only. I have seen too many units with frozen lines by using this method (myself included). It takes approx. 1 1/2 jugs of juice to winterize and less than an hour to complete. Why take the chance?

Mike, did you get this problem resolved? I have a 2012 31FK, tried to winterized today, and appears to have the same problem, pump runs but does not suck up the antifreezes my pump does work in Normal position, and with some coaxing I can get it to pull water into the tank in the country fill position, just doesn't like the winterizing setup. Thanks!
