Water Weirdness

[Al - K4GLU]

What would cause water to drip out of the fresh water tank overflow hole when you're hooked up to city water?

Picked up a new 23' FB Flying Cloud from Colonial last week. Spent the first night in it on their lot and they have no water hookups. However they had filled the fresh water tank before I took delivery of the trailer.

Am now at Jersey Shore Airstream Haven and have been here for 4 days. Yesterday afternoon I noticed that water was dripping from the overflow. Since I took a shower and used other water from the fresh water tank and have not added any additional on top of what Colonial put in the tank should not be completely full.

It seems to me water is somehow finding its way back into the tank through the water pump. Could something be hooked up wrong to cause this - or could it be a defective pump? I'm going to be in Jackson Center in 2-3 weeks so can get things taken care of there.

Anyone else ever run into this and if so what was the cause?

Speculation - leaking check valve???

It also COULD be leaking past (through) the pump -

Should be a minor warranty fix at JC.

if I might ask a silly question, where is the overflow?

The overflow is a small hole with a screen over it right beside the tank fill inlet.

thanks, never really looked for it but since you were talking about it i thought i would learn something new since the owners manual is lacking in details

We purchased our 23' fb from colonial, and if you are still in NJ, call Patrick and schedule to come in, sounds like they need to replace the water pump. A failing check valve will allow water to continue to fill the fresh water tank. It would be a quick install, the water pump is below your closed on the kitchen side.
