Glad to be a new Eagle HT (2016 28.5 RLTS) owner! Not glad to be starting out with a problem!
We have had our Eagle for 6 months now and have already had her into the dealer...and they couldn't find the problem, in fact it never happened to them!
So here is the issue.
about 5 months into our camping (?maybe 60ish nights in) we noticed water coming from under the kitchen sink a few minutes after taking a shower. Our model has the kitchen in the middle and the shower is on the opposite side.
We check all the obvious culprits, fittings lose (no), water in the basement under the drain (no) brought it into the dealer, they did a test where they filled up the tanks to check for a leak and rechecked fittings....nothing!
Discovered there is a exhaust pipe under the kitchen counter top and thought maybe that was over flowing ...no. We would dump every couple of days so we weren't overflowing
When it first happened we would keep our drains closed, now we have started opening them before showing...but shouldn't have to do that. We haven't had it happen since we are opening them....
Anyone else ever had this happen? Could the tanks be vapor locking when the values is closed???
