3006w water pump?

[kaferman]

While on our 4th trip in our new 3006w, I filled up the fresh tank just to make sure all worked. After about 5minutes the pump stopped and we had good pressure. But, just 2 minutes after that, no pressure. I could hear the pump running, for at least 10 minutes but nothing at any faucets. I have seen some rvs that you must switch when going from city to tank for fresh. Can someone verify that on this? In the panel where the filter is, there are several valves, nothing labeled and they appear to be a bypass for the filter( I assume for winterizing). My previous TT's did not require switching.

Sounds like a fitting is cracked or separated on your suction line. There is also a plastic filter screen on that line too that can loosen and let it suck air.
