After buying our 2012 Keystone Cougar 26SAB used in 2014 for a great price, we traveled around for two seasons before this year deciding to park it for the season at a semi-local campground. We struck gold and made all sorts of friends, so we're staying, probably for a few years.
A couple of weeks ago, I noticed a slow drip underneath the RV and when I got down there, could tell the water was blue from my black tank chemicals ... bad news. I tried sealing it up with RV aluminum roof tape but wasn't really surprised when it didn't hold.
It's leaking from a barely perceptible crack around the center end drain hole and there's also a very slow leak from the valve. The valve is relatively new, replaced by the dealer in the spring of 2016 when the galley grey was replaced under extended warranty. My first thought was that they screwed up the valve replacement and cracked the tank. Sadly, the warranty has expired and even if it was active, I don't want to haul it out of the campground after we just got everything set up the way we want it this season.
So my options are try to seal the leak in some way or find a mobile repair guy to install a new black tank and valve on site. There are a couple of certified RV repairers in Vermont that I can call but I first thought I'd check with everyone here to see if there's a way I can DIY it to stop the leak. If pictures are necessary, I can do that next weekend when we're back down there to begin winterizing it, but if I can't repair the leak, my antifreeze is just going to run out and the tank will be dead on arrival next spring anyway.
