Fresh Water Tank

I think I saw a post on here, but maybe on Airstream Addicts. Our fresh water tank went from being 50% full from our initial delivery from the dealer to 100% full without being connected to the fresh water intake, but is connected to city water. We were running on city water exclusively for a month and maintained this 50% tank level and then it started filling up on its own. Why would that be?

Hi

The tank will fill if the reverse flow valve on the pump is defective or simply has a bit of crud in it.

Check valve properly just stuck. It happens a lot is not considered an issue or defective. Here's the fix. Turn off City Water, I would go so far has to say to disconnect the hose altogether, then turn on your water pump and use the water that is in the tank until gone, then reconnect back to city water.

Also, check the door/port on the fresh water gravity full port. If pressured water is getting into the fresh water tank from city water, it would overflow out of the fresh water tank vent next to the filler port was a certain pressure was reached.

I think that it may have been leaking near the fresh water intake, but it was raining when this was happening so it was hard to tell. We have been running off the fresh water tank. It has gone down as we have used it and has not gone back up. So using the water pump may have done the trick.

Since it rained, pop open your outside shower door and see if it's trapping water. I just dumped mine out again last night and cut bigger slots in the foam gasket at the bottom.

When I got my AS (Used, but hardly), I was unclear about it's history as far as water tank went, so I pulled the bung in the bottom of the tank and flushed it thoroughly. Literally hundreds of shards of plastic came out. Remnants of the hole milling process, I suppose. The debris screen in the filter downstream of the pump would catch most of them, but I would guess that some are small enough to pass through to the pump. I suspect that many check valve fouling instances are the result of this trash.

Thought this had been solved. Used up the fresh water tank this week. Put the city water back and on used it for 2 days. Came back and fresh water tank was filled back up.

Consider replacing the pump diaphragm, or opening it up and cleaning it out, there may be dirt in there it cant flush out. You'll need to turn off water for this. You should be able to use a 1/2" nylon plug to plug the line from the pump while working on it.. The only way for water to get in there this way is backwards through the pump. Down the road consider getting a suction strainer for the pump, adding a check valve or shutoff valve on the pump discharge.

Hi

Since crud is one part of this sort of problem - do a really good flush of the tank and pipes before you swap out parts on the pump. Better to do it before rather than after.
