My husband and I just bought a 2006 KZ Frontier 2505. We de-winterized it today, intending to take it out for the weekend, but when we filled up the water tank it started to come out from the pressurized intake valve when we turned on the water pump. We followed the de-winterization instructions to the 'T' and cannot figure out where we went wrong.
I think you might be referring to the screw on connection for a hose to connect directly to the unit.
If that is so, what often happens is that when people winterize they know that they have to get antifreeze into that little bit of pipe. So what they do is press the little button in the check valve when the antifreeze is under pressure in the line.
Unfortunately, that almost always results in a sudden gush out of antifreeze, and the tiny flapper inside the valve loses it's seal. The correct way to winterize that part is to have no pressure in the system, push the tiny check valve, and turn on the pump for a second or two until pink comes out the valve.
They are a bit of a bugger to fix, and it's most likely easier to just replace the check valve with a new one from an RV supply shop. Only a few dollars.
On the other hand, you might be referring to the safety valve on the top of the water tank. There is a release position, and a normal position on the safety valve... If neither position will seal, replace the safety valve.

As I have posted before, I finally removed that stinkin' little plastic check valve and replaced it with a hose fitting with a shutoff valve. No more problems.
My inlet now from inside to outside: manual shutoff, pressure gauge, quick disconnect. I snap on the water hose, check the pressure and open the valve. When I disconnect I always shut it off, then it's set anytime I want to use the water pump.

The check valve in my flo-jet water pump got clogged last year, and I called the nice service tech at flojet and he talked me through how to clean it out. I was shocked at how one timy piece of sand can keep the entire system from pressurizing. Lesson learned: if your RV manufactorer skimped on a filter between your fresh water tank and pump, install one yourself...
Sounds like a defective check valve to me. The place where you would connect a water hose to the trailer, is that where the water is coming out? If yes, the check valve is bad. Take it out and go buy a new one install it and go camping.

That is what we did for years with our last camper.
