Question 2015 Ventana LE fresh water tank

[Old-RV'er]

In the first picture, that is sort of what I have, but one position is manual and one position is autofill. Ours is 2019 Ventana, see picture attached from Owners Manual page 124. I have noted our valve setup.

@Old-RV'er very interesting valving arrangement, Newmar inconsistency once again. Does your coach actually autofill the fresh water tank?

We've gone way beyond the original poster's @skychs dilemma. It was never mentioned if in fact the fresh water tank was full or at any level to begin with. I know that until I further investigated why my Ventana LE had "autofill" on the DigiLevel panel, but not in the wetbay did I learn what I tried to discuss above. I made the same assumption on my first trip about autofill, but had to figure out why it kept timing out and never filling...because I have only a part of the system!

@skychs might I suggest that you use the signature feature to let us all know what type of coach you're working with to give possible helpers more insight in our help.

Yes, if the valve in picture is set in autofill, (where I leave it), and I select the AF button on the panel, it will consistently autofill tank once drops 50%. If I also select the "top off" feature it will do it at any point below 95%. I have overfilled the tank by turning off AF on the panel, but leaving AF selected outside, if the hose bib is on. Normally after fill event I leave it off. They must both be on or off (manual Fill). Don't forget to use pressure regulator, as warnings all over the place of damage if pressure is over 60PSI. Believe disparity is because some gas coaches don't have AF, the upline gas one I think does, but, not sure if all diesel coach's have it as well. Ours may have it because we ordered all electric unit, and that caused the macerator toilet and couple other things to be added I was not aware of.

@RandyB - mine doesn't have what yours has, so yeah, inconsistent. Best for someone with a question to give us a picture of their setup as we can't assume it's like ours.

I finally got the chance to get a photo of my Ventana LE water/sewer panel. I have the basic set up in my coach. Some of the valves/knobs are even stuck so I can't open or close them. I wanted to sanitize the fresh water tank then clean out the hot water heater before I leave for the weekend. I guess its time to go pick up a new anode rod too.

Same setup as mine. For your IMG_4667 that's the manual water fill, only use that when you in fact want to manually fill such as topping off prior to boondocking somewhere where there is no water.

The 4668 photo are low point drains to empty the tank such as for sanitizing. They may be stiff.

The 4669 photo with A and B markings is for winterization.

All of the black knobs only turn 90 degrees so don't force them but they can be stiff.

AutoFill is controlled by your tank level panel in the electrical panel over the stairs. Press and hold the autofill button to turn on or off and sometimes if filling from empty it will timeout and you'll need to reset it back to ON. Also if autofill times out regularly it's a good sign your house filter (in the wet bay, white holder) needs to be replaced. I replace mine quarterly.

A point of clarification, from my coach anyway. The “low point drains” as shown on the white panel are in fact low points in the plumbing lines. One hot and one cold. The fresh water tank drain is nearly hidden. Look below the 2 low point drain valves, in the open space, on the wet bay floor level, now look inboard towards the rat’s nest of tubing. Down there, on the floor is another valve that is the fresh water tank drain. A simple ball valve that only turns 90 degrees.

@skychs your white panel is exactly like my LE. The DigiLevel panel has the autofill verbiage on the display. I have physically confirmed that my LE does NOT have the required solenoid operated flow control valve required for the autofill function. I’ve become accustomed to ignoring it. I can only fill my fresh water tank manually by the valve on the wet bay white panel “on-off”. I simply fill it until the tank overflows and close the valve.

Today I got the valves to move. The two low point drains (hot and cold) and valve B were stuck. Once I was able to open the low point drains I could see where they drained from the coach. I discovered the third valve last week when I flushed and filled the FW tank the first time.

When I got valve B open I could see the suction in the pickup line ... the line Im going to use when I get back for sanitation. Once I get the fresh water tank sanitized Ill install the new water filter.

I don't see anything that says Autofill. The last time I filled the tank I did what RandyB did .... I just waited until it started over flowing.

I also drained and removed the Anode rod from the hot water heater. The Anode rod was fine but with a flashlight I could see the limescale deposits building up inside. I heard vinegar takes care of that so that's next. . One day at a time.
