New Trailer, a little concern with black flush system
Think I have a little issue with my black tank flush system. Sunday after doing final pack up, and I was emptying the black tank, and hooked up my gray hose to my black tank flush system, turned it on slowly, and let it do it's thing (typically let it run for 10m), while I was packing everything else up, and noticed some water dripping from the back left of the trailer, and the left side of the fender well. Also noticed a little water in the bathroom, but I didn't have time to really look into it.
Once I got home, I started looking around, and did some research about it, and I think the issue is the check valve, under the sink (See Picture). My check valve seems to look different than some other ones I've seen.
I was also not using a water pressure regulator when I was flushing the black tank.
Anyone have experience with this?
Trailer in question is a 2017 21LHSWE
