New to Georgetown 378xl

Hello to all,
We are new to Forum and to Georgetown 378xl and taking our first East Coast beach trip. We have a 2018 which we bought new in Dec. of 2019. First trip and of course have some learning curves and lessons to be learned about a motor home.(previously travel trailer family). Here are a couple questions? Maybe should be multiple topics not sure??
1: We have a smell in the closet behind the bathroom, smells like sewer??
2: while trying to “flush” we had water pour out of the Same closet somewhere and flooded our clothes. Luckily caught before any damage.
3: There appears to be a LED lighting strip behind the outdoor tv and we can’t for the life of me figure out how to turn on!!
As of now we love the RV but the Mrs. Definitely wants the smell gone!!! Any help would be helpful and glad to be a part of the forum!!

When you wrote "we bought new" did you mean "New" as in never titled before or "new to you"? If the former, you need to get that thing to the dealer to get that leak fixed immediately. That absolutely is not normal and will result in rot and mold. Many dealers will prioritize leak work ahead of other people; I know ours will.

It sounds like a pipe separation or crack.

Is this only from the half-bath toilet and the full bath in the rear is OK? Or is it both?

If it's "new to you" and not covered by any warranty and you do not have the experience to tackle that kind of work, try to find a "mobile RV repair" service near you. A quick search for Georgetown, KY showed a few possibilities.

Good luck,

Ray

When you say "flush" are referring to the black tank cleanout (flush)? If so the vacuum breaker-check valve for the cleanout is located in that closet (closet has washer/dryer prep) probably tied to the plumbing in there and it may be leaking. It may look like this:

Yes new as in never titled. Also it is the “flush” to the black tank or at at least that’s what I assume. When I used the “flush” we had clean water come from the closet in the bedroom behind the bathroom. This is where the washer dryer would be, if we had one. I’ll attach a pic. The smell seems to have dissipated some after ensuring calves were closed and only dumping when getting full.

I don’t see one of those in my closet. You thing that’s what the blue pex lines are?! If that is the connection to my flush that would make a tone of sense and maybe where the smell is coming from if it’s connected to the black tank?! Just a thought??

That is the first GT378 I've seen that didn't have the valve in that location. It may be the valve was never installed and that would explain the open pex tubing. You could hook up your flush port and see what happens with low water pressure or maybe a compressor pumping air into the flush port to check.

Thank You!!! That looks like it. If that is the other line to the black tank then that would be the smell also I’d think!! Thanks for the help!!

OK, thanks. When you wrote about toilets and black tanks and used the word "flush" I thought you meant the water leak and smell occur when you flush a toilet.

That's not it, right?

So by "flush" do you mean "dumping the black tank of its contents" or "running fresh water into the black tank to help it stay clean"? I think you mean the latter.

We have a 2016 George Town 378 XL and have never had that problem. When you connect to the tank flush with the water running you MUST have the valve open when the water is running.

You are referring to something that is not part of nor has any useful information toward this thread.

Thanks to all for the quick and helpful reply!! Truly it is appreciated!! I just covered the lines and it appears the smell went away also. When we get back to the dealer I’ll make sure to get the part. THANKS AGAIN!!

OK, I think you're referring to emptying the tanks and that is normally called dumping, not flushing.

This can get confusing because the black tank actually has a "flush" fitting. You hook a hose to it and there's a kind of sprinkler head inside. That washes stuff off the walls and other section of the tank to try and keep the black tank cleaner.

Good to hear bubbles figured the problem out, again.

What you are looking at is the hook ups for the water and drain for your washer. I am in the process of installing a washer/dryer combo. That 1 1/2 inch pipe with the screw on cap has a p-trap which will keep the smell from coming from the black water tank. When you tried to clean your black tank, watch out for using too much water pressure.

Good luck

I think he/she got confused by the use of the word "flush" as did I.

i have a 2016 378 xl and the black water flush valve everyone is talking about was installed backwards. could not flush the black water tank. had to remove and reverse it. bought the tool from lowes and just cut the line and reversed it. no more issues. but it appears you will need to purchase a valve and install it. i used an air compressor to find out which hose came from the outside for the flush and knew which way to install the valve.
