Filling the water tank

I don't know if this has happened to anyone else but I was filling the water tank and all of a sudden it would not fill. Matter of fact, it regurgitated on me. The tank was only half full. Not sure what I did but to fix it, I ran the water pump and this cleared it up.

 

Me thinks it's an Air Bubble... or something like that... a flood of water into a pipe with air in it, can cause it to 'Belch' as the compressed air bubble breaks loose..
Just recalling somethings in the past, others will have a better idea, but that's my initial thought.
Just pour in slowly so the trapped air can escape.. should be ok..
Hope that helps..

 

Frank,

I am sure you are right. I am sure I was trying to fill it too quickly. Fortunately, turning the pump on and running the water dislodged the bubble.
