Fresh water pump

[allanmet]

My fresh water pump stopped pumping water on my way home last year so I bought a new pump and installed it as we are getting ready to leave for a trip this year. The new pump did the same as the old pump. The fresh water tank is full, I hooked a separate tank and line to the pump and the pump emptied the tank but still no water to the sink, where did the water go? I'm lost, and ideas?

I realized my antifreeze was "disappearing" as I pumped it in and it wasn't coming out the sink faucet. Walked around the back of the coach, carefully avoiding the pink puddle, and closed the low point drain. Worked fine after that.

air relief line blocked by bugs etc.

pumps can't pull a vacuum on the tank ?

does the toilet flush, basin and shower work ?

Could it have lost it's prime?

+3 or bad check valve, but likely the first.

+2 I've forgotten that myself several times after filling the water tank and then wonder why the pump isn't getting anything to the sink. 😮
