Water drain

I parked my FR3 on a slight incline tonight and water was gushing out of the overflow drain. I assume it emptied because of the hill I was on? Does anyone know if there is a cap that is supposed to be in there that possibly fell off or is it simply because of the incline?
Thank you...

Are you hooked up to city water? Seeing as the water is 'gushing out of the overflow drain' it could be the check valve in your water pump allowing water into your onboard water tank.

Thanks for the reply. I was not hocked up to city water, I was simply parked on an incline and the water pump was not on. Any ideas?

Most likely water out of the overflow. Which doesn't have a valve or cover so the water can overflow as needed.

On most units the overflow is the vent which the tank needs to stay open or it would collapse. Depends where the vent is located. If you have water you should be on level ground, Don't know where your vent is located most are on top but there has just been a post about a vent located about half way down. So there 35 gal tank can carry only 17 gals. That's just a great design by FR.

Interesting. I just filled up the tank until overflow occurred. It isn't just draining the overflow though. It is draining the entire tank.

Siphon effect.


Try turning on a faucet inside to see if that breaks the vacuum.

You can drill a small hole a the top of the overflow loop to help break the siphon. Works for me and a 1/4" hole is easily plugged if you decide against it.

You need to have a "p trap" put in to the overflow line. It you don't water will siphon out until your tank is empty. It's an easy fix and covered under FR warranty.
