I just installed a new water pump...on the coach--before I did the old pump did not pump the anti freeze very well so thought the pump was gone...the new one does't pump all that well...I have an 03 W...
Pumped 3 gallons of antifreeze into the fresh water tank before I realized the valve was turned to "fresh water fill". Drained it in a bucket and started over, this time with the valve in "Normal" position. Took an extra 10 minutes, no biggie!! Lesson learned.....??
