I have a 2023 D290 RLT, the campground I'm at has extremely high pressure and I don't have a regulator. So going to fill the fresh water tank but I do not see an overflow line out the bottom of the camper. I have the two low point drains and then there is two red Pex pipes sticking out about midway of the camper. Have no idea what they are for. I would think the overflow would be a white hose that is similar to the ones attached to the pump.
I did fill the tank halfway but afraid to fill it until water runs out. Because I think it will be in the under belly.
Any suggestion

Typically the overflows are PEX, mine are red, but I wouldn't be surprised to see some blue ones. If there isn't a valve on the end of the tube, its a safe bet it's a vent or an overflow.

I have a Durango 301rls and my water over flow is on the side of the trailer by my on water demand. It is the vent for the tank.
Hope this helps.

There is two red pex that appear to be overflow lines both are just down from the low point drains. The only way I'm going to know is fill it up.
How many of you use a water pressure regulator. I looked online and TSC has a brass non-adjustable Camco in stock. I will give it a try see what happens.

I have two red pex lines which overflow when the tank is full. Camper is a 2021 Durango D250RES. I don’t use a pressure regulator but use a Camco inline water filter. I used to use a regulator but it dropped the pressure too much for my liking.  |

The un-adjustable ones are known to fail, or otherwise not properly control pressure. Yes, I started with one of those, but recycled it when I got the adjustable one. Lyle |

I looked online and TSC has a brass non-adjustable Camco in stock. I will give it a try see what happens. The water tank has vents that many call overflow pipes. they can be any color or type depending what scraps are available. The inline pressure regulators may be better than nothing, but get a good one when you can. What I found was that the cheap inline types may reduce the flow to a trickle under certain uses and pressures, just checking flow from a hose is not a good test. A good way to determine the quality of RV accessories is to look for the name Camco and then try to find another brand. |

Thanks Catman mine looks just like that. I fell a lot better about filling it all the way now. Be aware that, depending how how they ran those lines, you can actually siphon water out of your tank. I had that situation with my rig and lost probably 10 gallons driving into our old boondocking site. One reason that I always bring at least 1 "blue cube" of water besides what's in my tank. Local KZ dealer pulled down the belly cover and re-ran the vent line OVER the frame to stop this, mostly, from happening. As an aside, one of my biggest pet peeves is that mfrs won't use water tanks that have a low-spot pickup or a "high-spot" vent. You can end up losing 10-20% of your capacity due to the aforementioned siphoning or simply not being able to pick up all the water in your tank. Lyle |

All good information, only thing I could get is a camco inline with a gauge. It is not adjustable but it has me up and running, for now anyway.
Thanks

I tried the non adjustable ones and all they did was restrict flow. |

Lyle This does happen and it just happened yesterday when backing into a site. Didn’t lose much though. The worst part when filling is tank shows full on screen but doesn’t overflow for about 3-4 minutes after. Got to love those accurate sensors lol. I have the app on my phone so I watch it when filling. |

Lyle My KZ270thle has a vent right at the fresh water fill. No overflow on the tank. I fill it til the water comes out the vent. No chance of siphoning water with the vent that high.

There is no such thing as water siphoning out the vent pipes, it is a spill plain and simple. KZ has no clue that water runs downhill and have been building with pipes attached near the top of the tank and water spills out when the trailer leans that way or when you round a curve sloshing water that way. I corrected mine by adding a gravity fill like you have. I also moved the pickup tube to the drain port so all water is available for use. |

Mine is about 2 inches from the bottom of the tank. Maybe they were trying not to use the the water at the very bottom due to some crud laying there. But then again, they would have to be thinking.
Same as the tank sensors not being far enough apart on the sides of the tanks vertically.

My old Komfort was that way but it was gravity fill. Wish my KZ was the same way. Lyle |

Excellent idea on moving the pickup to the drain, but it assumes that the drain is actually on the bottom of the tank. Lyle |
