Water Pump Woes
Yahoo Message Number: 126500
I was winterizing my '03 Mid-Bath this morning.  I had already pumped two gallons of anti-freeze into the system.  I got the third gallon ready to go (placed the input hose into the anti-freeze bottle) and when I turned on the pump switch, the pump just made a low buzzing sound and there was no suction.  The fuse is not blown.  Is there some kind of reset switch, or does this sound like the water pump has gone bad? Thanks for any insight.

Any chance that air got sucked into the pump causing it to loose priming?  I know when I drain our system, it sometimes takes a while to get the pump to reprime itself.  The pump just sort of hums until it starts pumping properly again.

Joe, sounds like the same problem I had a couple of weeks ago in my 2003 MB.  This was my second Whisper King to go bad.  If replacement is necessary I highly recommend the new Revolution Pump.  Slightly more noise but much better performance.  Just swing your P-trap out of the way and mount it slightly forward to clear the trap.  All water fitting are the same.

Thanks for the replies.  Art, thanks for the suggestion about allowing the pump to prime.  I did that for several minutes with no results.  I'll be checking into the pump that Joe Hamm mentioned.  - Joe B.

--- Just a FYI... the Whisper King in my 2003 takes a lot longer than "several minutes" to re-prime after draining and flushing the hot water tank (for example); the last time, it took at least 30-40 minutes before it kicked in!
 While you may indeed need a new pump, it could be that your current pump just isn't getting a chance to re-prime on its own timetable! ;-)

As Art and Joan have mentioned, it sounds like the prime has been lost. It can take a long time to prime once it has been lost. Running the pump dry,  for 10-15 minutes doesn't hurt the pump.
Try this. Set the bottle of anti-freeze on a stool so that it is higher than the pump. If possible, pre-fill the intake hose with anti-freeze.
I would go as far to use a turkey baster to force antifreeze into the intake hose. Once pumping, do not let the pump run dry again, shut the pump off. Are you filling the hot water tank?
 Since you are ready to install a new pump, you have nothing to lose by letting the existing pump run in an attempt to prime.
If your pump turns out to be good, go ahead and buy a new pump anyway, for a spare. Today's pumps have short lifespans and always die at the most inconvenient time.
