Fresh water from tank disappearing

[DonaldJP]

Hi, We have a 2021 Imagine model 2610ML which we really enjoy apart from the fresh water issue. I fill the tank and by the time we get to our destination the tank level is well down and there are no apparent leaks or water dripping. Any suggestions about why this may be happening or what else to look for. Thanks, Don

Do a s3srch on here regarding the siphoning effect. It's been covered many times. You're basically losing that water through the overflow tube. Easily fix with a Sharkbite ball valve. Just need to remember to open that valve before turning on that pump, or else it might implode the tank,

Combine the ball valve with a tee and some PEX terminating at a location above the tank, raising the vent and the problem is fixed. Only open the ball valve when emptying the FW via the dump valve
