Just purchased a 2013 27 flying cloud. The monitor says fresh water empty. I spent the key-protected port, place the clean water hose, and turn on. Within seconds water backs up as if the tank is full, yet the monitor says tank empty? I will try the outdoor shower to empty the tank and refill it? Am I not getting the freshwater tank full or is the monitor bad?

Otto, my guess is you are trying to fill the tank with the hose pushed pretty far down the inlet, and the flow rate too high. The tank can't vent properly, and the water is coming back out the only place it can. Try to slow down the inlet flow and pull the hose out till a few inches are in the inlet. Just my thoughts. Mike

I have slowed it to a trickle, put it in the tank, opened one of the faucets inside, and it still won't take water? I had drained the tank with the petcock and there was very little water in it. Stumped.

Open the drain and see what comes out?

My 2012 FC 28' had a bad monitor and it needed replacement. You need to have your dealer check it. Bobby

I had to purchase an adapter hat attaches to the hose then place the tube into the inlet then turn the water on. I don't have a photo but camping world had them on sale. The think it is called simply enough...water filler with shut off valve. Hope this helped. Sorry no photo.

Hmmmm, is it possible you have a kink in the hose that leads to the tank? Or the hose pinched?

OTRA15 · 07-17-2017, 12:49 PM

Can you ask the previous owner who just sold you the AS? Ditto to MollysDad about a kink in the fill tube between the inlet and the tank.

Ditto to suggestion to open the tank drain and see what happens. Your monitor may be shot, but a low flow rate of water into the water inlet should fill the tank until it overflows out the fill inlet port.

Good luck!

Peter

I have had this happen on two trailers. Both were caused by kinked air relief hoses that went from the fresh water tank back to the vent at the filler location. Replace, re-route or simply in-kink and twist so the kink is not an issue. Try it.

HowieE · 07-17-2017, 02:56 PM

When you open the fill port on the side of the trailer you should see a hole for the hose an there may be a smaller hole with a plastic plug in it. That is the vent port and that plug has to be removed to releave the pressure in the tank as it is filled. Without a vent path you will get blow back no matter how slow the water is added.

Try drawing water in the trailer via the pump. That will tell you if there is any water in the tank.

greghoro · 07-17-2017, 03:08 PM

2013 trailers used MicroPulse tank monitors, notoriously inaccurate.

Try draining the tank for a few minutes. If no water or small trickle, most likely not the tank monitor. If a strong flow, let it drain for a few minutes and then see if you can add water without the immediate spill-over you encountered. If you can add water, then monitor needs re-calibration. If immediate spill over, then some sort of blockage in the filling tube. Note, this will obviously remove some water from the tank which you might need in case you have to go camping and have no time to correct the problem of not being able to add water.

Note, when filling the tank, always make sure that the portion of the hose you place in the filling tube does not take up the full inside diameter. You want room to breathe, even though there is a separate breather tube. I've seen a thread where a person caused their fresh water tank to balloon due to the pressure encountered when filling using a hose that had a snug fit inside the filling tube.

A kinked air relief hose should still allow some water to flow down the fill spout tube to the tank, if the flow coming from the hose is very light IMO. The air in the tank simply comes back up the same hole, per the next post.

Not necessarily . . .

If the hose is set real slow to a trickle, this small flow of water will go down the fill spout piping, which is at least 0.75" ID, if not 1-2" ID. Air in the tank can come back out the same pipe, as there is plenty of extra cross-sectional area inside the pipe, with only a trickle of water going down.

Just like when you pour water out of a water jug. If you do it slowly, it works fine without the air vent hole being opened.

PS -- If some critter crawled inside the fill pipe, however, and took a very long nap, it could be totally stopped up, but this is unlikely IMO.

FWIW AS under warranty just replaced our micropulse as readings indicated wild swings even 30 minutes later. Also FWIW I hear that the mfr of Micro Pulse is leaving the business. A thread from a few weeks back had many posts re conversion to SeeLevel systems.

https://www.rvupgradestore.com/RV-Ta...stem-s/164.htm

As for the filer, I use one of these but from WM. I throttle it back with the thumb-lever shutoff and it helps with a slow and stead flow. Unless you filled the tank with your water source, I would also drain the tank completely and refresh it with some chlorine...it takes very little. Many threads on the subject.

2X what others have said re blowing out the vent line with a compressor and puling the face plate and check for obvious kinks.

What HowieE said.

Camping World website was down this AM so I could not post a photo or give you the link to the $5.00 tool that will fix the problem. It is called Tank Filler with Shut Off Valve. Please try this tiny little, cheap fix before driving yourself crazy. Pretty darn sure it will work.

OTRA15 · 07-18-2017, 04:36 AM

Unless the fill tube is totally clogged, a tool like that is not necessary if the water flow in the hose is low enough.

Keep it simple, Stu . . .

PS -- Good advice from Bob to replace tank water and sanitize system with bleach etc..

xrvr · 07-18-2017, 05:04 AM

Betcha the tank is full.

When you turn on the pump, does any water come out of the faucet? [Don't leave the pump on for more than a few seconds if no water comes out.]

Could you give us a status update please?

Thanks,
