As mentioned I mistook this vent for the HWT drain as it was routed over to directly under the HWT and a valve installed on it from the previous owners. I have traced it back to the fresh water tank so I can confirm it is indeed the tank vent
I assume the owner put the valve on the vent so they could travel with the tank full without losing the water.
I already put a sticker on the water inlet to make sure vent valve is open to avoid another incident of pressurizing the tank inadvertently
Now if the new pumps fixes the pressure issue then I am in good shape. If not I will have to see where there might be a blockage but lets hope this fixes the final piece of the puzzle
That is a very good guess, I have read many reports on people filling tanks leaving to find near empty tanks when they are, that water will siphon out. I believe that I may have that problem. I have 16 more gallons of water in my KZ than I did in my old Komfort, yet we ran out of water after a 4-day boondocker. Yes, it could be that we used more water, but I don't think so. I'm going to meter the next fill and see if I actually get the stated 61 gallons. Given that there's one person here who's "missing" about 15 gallons between what he's metered in and what the spec says, it's a concern. I also need to double-check my placard to see what =it= says, too. I simply can't remember if the yellow tag gives a water weight or not. I =know= Jayco does that. Lyle |

Fill the tank and the watch in the mirrors as you round curves, my trailer left a solid streak of water whenever the road curved to the right. The tanks were made with two vent pipes attached at the top and then went straight down towards the road. That ain’t a siphon, it’s a spill, plain and simple. Think of your tank as a bucket, tilt it or rock it back and forth, water spills out. Now add to that, they attach the pickup hose to the side of the bucket so that the last 20 percent is not accessible.

OK so update on my journey with this trailer. Vent issue has been sorted out but we are still struggling with the pump. Will not pressure lines to the point of shutting down pump. Never reaches 40 psi to trigger pressure shut off
1) system works perfect with city water but water is inconsistent with pump and has a lot of air in the line. not sure what is normal but pump runs inconsistent and pumps water in spurts as opposed to consistent flow
Here is what I have looked at or adjusted so far on the pump
- replaced the pump
- replaced the hose from tank to the pump
- Checked to make sure no blockage at tank outlet
- Checked all lines to make sure no blockage in any of lines
- Tried with tank full/half full and quarter full
- Tried pulling water from pail not tank as well as tried pulling from winterizing hose. Same result
-Pressured up the lines with city water and then switched to pump and after a few seconds back to same intermittent water and air
I am getting air from somewhere or I have inconsistent power to pump that is causing pulsating pump
Any thoughts?

How about the ball valve for winterization? Or perhaps the ball valve that switches from city water to pump? One of those may be leaking air in. Any way to cap those entry points off and see if it helps?

There should be a strainer before the pump, did you check it and the connections?

Could it be an electrical issue. When I was messing around with the pump I discovered that when plugged in to power I can feel current in the frame when I touch a small piece of the trailer hatch where the paint has rubbed off so wondering if it might be something to do with the electrical.
It looks like the last owner of this trailer chased this same ghost as a lot of the stuff I have done with water system looks like he tried already so I wonder if electrical might be why the pump is pulsating an not steady stream of water as it should
Thoughts if this is possible and if so where could obvious culprits be?

First, Google "RV hot skin" and read, this is dangerous. Do not continue on till this is corrected. Do not touch the trailer while standing on the ground, use a rubber mat and rubber gloves at a minimum.
No, air in water lines does not come from an electrical problem, it comes from a leak that lets air into the water system. I asked you about the strainer that you call a "filter", because they are often the source of an air leak, improper winterizing can cause them to crack. Follow the water line from the tank, thru the valving, thru the strainer and right to the pump.

Please DO NOT ignore or discount the danger of a "hot skin" condition. If you don't have strong electrical knowledge, please take it to an RV dealer who does or find an electrician who understands how R.V.s are wired, as they have some differences than standard household wiring.
