What did I do? Convenience center/water issue

[Travelin’ Gran]

Hi!
Just had a bunch of company sharing our 3150RL 2010 over the weekend and thought I’d save my DH the task of cleaning the black tank. I let it go( we are hooked up in a full service site) pushed the valve back in and then pulled the grey- then pushed that valve back in. For good measure, I thought I would use the “no fuss flush” to be sure it was all tidy. I pulled the black tank valve again, hooked up water to what I thought was the flush, and turned on the water. Nothing seemed to be happening as I was checking the black drain hose. I turned the water off- only to find it was now dripping in the giant basement and the floor by the shower, fridge and steps was all wet. Grateful for heat to dry it all out, but did I damage something? Is there somewhere I can check? I can’t find anything online or in our manual, and I’d like it all done before DH gets home late tonight so it’s not more work for him! Thanks in advance for the help!! I was using the third connection from the top- under the sewer flush label.

One possibility is the anti siphon valve leaking. It prevents water from the black tank rinse line from going back into the water supply. It is often located up high under the bathroom sink. They often fail or stick in the wrong position. Look under the sink and see if something looks like a valve at the end of two hoses.

Check your tank level lights to see if the black tank shows full. It’s possible that when you reopened the black tank the cable disconnected from the valve and didn’t open. If that happened and you left the water on long enough you may have overfilled the black tank and it backed up into the toilet and overflowed. Hope not.

Take the time you have left before your husband returns to run as far as you can

[Travelin’ Gran]

No black water- everything smells fine and it didn’t overflow the toilet- just water under shower running down to refrigerator. Did I have the right inlet? I’m very confused now. Good chance to empty and wash out the basement

Your black tank anti siphon valve is leaking. Get rid of it ASAP.
That the panel off behind the connivance center. Follow the flush line going up into a wall. Find the other line that goes down to the tank. Cut both in such a way that they can be connected together. Use sharkbite fittings.
Just leave the dead valve in the wall.

The anti siphon valve got you. Take it out and deposit it in the nearest trash can. They are total junk and not needed. There are two kinds of them, ones that have leaked and ones that are going to.

The black tank flush system back flow preventer/air gap valve, if not under the bath sink could be in the wall behind where the water lines of the shower are located. Access to the valve might require accessing through the back of a cabinet. Also, why is the white hose connected to the winterizing inlet?? The photo shows where our valve is located, in the space where the pocket door is between the bath area and the kitchen area. I would have to create an access hole in the back of the pantry cabinet to get to the valve, but so far after eight years of weekly use of the valve it is still working quite well with no leaks. Also, the valve will be located, wherever it is, above the level of the rim of the toilet bowl, which is the highest point that black water could siphon from in these rigs, and that is why they are installed in these rigs.

On the 3150rl model they have the backside of that shower is the refrigerator there is no access to that valve if that's where it's at. That's why I suggested cutting the pipes in the basement and plumbing them together.

I'll be able to tell you for sure cuz my buddy just bought the same exact year make and model and will be removing his once I find it

I am also with the black tank flush anti siphon valve group. Mine was in the wall between my shower and the entry closet, in the wall where my pocket door is. Water flowed out of wall and down the steps. Yours is probably in the wall between your shower and your fridge, where your pocket door is.

I removed my valve and plumbed the lines together. But access to mine as fairly easy thru the back of the entry closet. You would probably have to remove the fridge to access yours. I would do as beeje said.

But in your picture, why do you have a hose to your freezegard connection?

[CruzinMooses]

If the picture is how you had your hose hooked up I can see the problem... The hose is hooked into the SUCTION port of the water pump that is meant for sucking antifreeze into the water pump for winterizing the water system. If that is where you had the hose hooked you PRESSURIZED the input to the waterpump which I would be willing to bet you blew of the line going INTO the water pump which would flood the basement and come out over by the steps also...

Yeah, I'm thinking those hookups aren't right if what I'm seeing is....what I'm seeing.

Yeah I just looked at the picture I agree let's definitely hooked up to the winterizing port. Don't know what water pressure would really do there. At any rate I would still get rid of that valve

[BB_TX]

She did say it occurred after she connected to the bottom connection, the flush connection. So I don’t think the hose to the freezegard connection is the cause of the leak.

BB she said that she THOUGHT that she hooked the hose up to what she thought was the black water flush hookup but if you look at the picture she has the hose hooked ti the winterizing port which is not meant to have a pressurized hose hooked to it. I would be willing to bet money that she blew a line off that caused a leak.

I definitely attached the hose to the third inlet down, which, by the labels I presumed was the black flush. The photo is to show you the layout of our convenience center
The other hose is where DH has our waterline from our campsite going in. We have water flowing fine in the taps in our trailer.
I think the check valve group could be right. It may never have worked-as I add tons of water through the toilet when we empty.

I can’t get under our sink properly. They’ve stapled a panel in under the lower shelves. I unscrewed everything and it won’t budge, but I follow the line from the water line in the basement to an area between the shower and the refrigerator where the sliding divider pocket door is located so I think the valve is still the right idea.

Sounds like you flushed the blank with the correct Port the third one down however your husband has the city water connected to the winterizing port. The city water Port is the center one.

Just to make sure go behind the convenience center and look at how it is plugged in make sure Keystone did it right. Wouldn't be the first time it wasn't Plumb correct or marked correctly

I think you are right.
As to the connection showing in the photo- , this is where DH has our campsite water going in. I think it’s where he was told to put it when we bought the trailer 2nd hand.

Ridding myself of the check valve sounds really practical. I would just need a dedicated hose for the flushing.
When I opened the water area in the basement there were a lot of lines! I should have taken a picture when I had it open! There were 2 lines that looked like hose rather than water lines. Would the hose-type be the check valve lines? I wish these things came with diagrams!

[beeje]

No the braided white looking hose does not go to the flush valve.. one of those probably goes from the pump to the tank the other one from the pump into the water piping system.

The water lines to the valve and all of the plumbing fixtures should be PEX like a hard plastic. Yours may be all the same color like a translucent white. Like I stated earlier the newer ones have three different colors. Red is hot water blue is cold water white for that check valve.
