City water connector?

[Orionpax235]

I just got a 2007 QUE RE and I can't seem to figure out how to connect city water to it. Is it okay to just have the water going directly into the potable water inlet?

If this is how I should be doing it how will the system bypass the water pump and maintain good water pressure.

I'm kind of at a loss here. I really worry about messing up the water pump or causing a leak.

Welcome Orionpax235!

Congrats on your new Sunny!

I have never been inside a Que, but I may be able to help you with your question. The Que was a new, unique-style camper for Sunline. While they changed how they were built compared to all the other Sunlines, I sense they did not change the water system.

There should be a "city water" hook-up fitting outside the camper. The fitting looks like the swivel female hose end of a standard garden hose. That city water inlet fitting should have a screen washer to keep dirt or other bigger debris out. Deep inside the fitting, which you cannot see if the screen washer in in place, is a check valve that keeps water from flowing backward from the city water fitting when using the water pump. If you can find that fitting, you would screw on a potable water hose to it to pressure the water system in the camper. This is common when at an entire hook-up campsite. See if you can find that fitting.

This post has pictures of the inside of that city water inlet fitting on the other non-Que Sunline travel trailers from the era yours was built. This post tells you "not" to push the check valve plunger in when water pressure is still left in the camper as it will blow out the O ring in the check valve. But you can see the valve "type" you are looking for https://www.sunlineclub.com/forums/f71/fresh-water-inlet-valve-repair-11736.html

Now to the water pump. Inside the water pump is also a check valve. That check valve prevents water from going backward through the pump and into the freshwater tank. So, when you are hooked to city water with a hose screwed into the city water inlet valve, the system automatically will not have water going into the fresh tank backward through the water pump. You do not run the water pump when on city water.

You mentioned,

Is it okay to just have the water going directly into the potable water inlet?

. If you mean, do you have water going directly into the freshwater tank fill spout? If so, that is only for filling the onboard fresh water tank, and when it is full, it will spit back water out that fill spout as the tank is full. Then, you use the water pump, which draws water from that fresh tank, pumps it through the camper, and pressurizes the water lines.

If the above does not sound like anything you have, post some pictures of what you do have, and we can help you figure it out, as someone may have changed something.

I hope this helps,

John

If you need help posting pics, here are the basics.

There are three ways to add pics.

1. Upload pics to a specific post, attaching them at the end of the post.

2. Link them in from a publicly viewable web photo hosting service you have.

See here for 1 and 2 https://www.sunlineclub.com/forums/f105/forums-101-posting-accounts-basics-11235.html#post86041

3. You can upload pics to the forum in your own personal photo album. Then link them to anywhere in the text of a post. See here on how to create an album. https://www.sunlineclub.com/forums/f105/forums-101-posting-accounts-basics-11235-2.html#post87945

If you still get stuck, let us know. Pic's go a long way in helping show things you are working on, and we really like seeing Sunline pics!

Hope this helps

John

Hi John B!

Thanks for the help here

I guess the crux of my confusion is this inlet here.

I assumed it was a black water flush because its directly over the black tank and the sewer connection. All other pictures I've seen online has the flush inlet next to the utility shower like this. The freshwater tank fill is a few feet to the left of this.

Thinking about it now after a full nights rest. It doesn't make sense to have a black water tank flush over a city water connection. I'll give her a test in the morning to be sure.

I checked the sales literature on the Que and a black water tank flush was not standard on those, nor was it an available option. Actually the Que only had two available options- the 14" Toshiba TV/DVD player and outside gas grill (bracket would have been standard though). Given Sunline did custom stuff, I suppose it could have been special ordered with a black tank flush, but that's pretty unlikely for a Que. Not many of those ended up special ordered.

Sunline was also very good about clearly labeling the black tank flush, even though it did have a similar sidewall connector. And those decals have held up fairly well compared to the Que graphics package.

That's great to know! I was definitely just overthinking it then. This is my first travel trailer so I'm still learning a lot. I appreciate the help. I think I have 99% of the original documentation here but I could not for the life of me find anything on what this inlet was.

For every Sunline floorplan since the mid '90s, they made a model locator sheet that tells you where the important things are. You should have one in your owner's manual binder, but they are also downloadable on here. I was surprised to see that the 5.4 RE locator sheet (and others as well) doesn't show the city water hookup, just the water fill.
