It used to be that when I used the auto fill system, all the floats would come to the top and stay there. Now, I notice that when I run the water thru the system all the floats pop up, but when I stop the flow of water thru the system, a couple of the floats drop back down. When I check the water level in those cells, they appear to be fine. Has anyone else experienced this problem?

I have the same issue, and contacted the manufacturer of the float caps. They told me that as long as the floats appear -- high, low, middle -- the water level is acceptable. If you can't see the floats, even part way up, then there's not enough water.

This seems to work for me, along with watching whether water comes out of the reservoir when filling. If it doesn't (water just recycles back to the reservoir), there's enough water in the cells.

So that's what I've learned from using the system and talking to the manufacturer.

On my 05 the floats were too long, Original ones was designed for a different battery. new floats supplied by WRV had shorter necks on the floats, They now work well.

My floats are factory installed, and they work reasonably well, as long as I see them moving.

My floats were also installed by WRV, they changed Interstate battery and they required a shorter neck on float, They didn't know there was a problem as floats were bottoming out and always showed as being full. not sure if thats your problem. good Luck

I had earlier posted a "help" thread because my slides wouldn't work, and it turned out that the house batteries were low, as suggested by several forum members. In addition, the batteries weren't holding a charge.

Turns out, when I took the coach in for service it was noted that the auto-fill system was not working properly, and a number of cells were either dry or low in spite of religiously using the auto fill system and fast idling the motor regularly when not going on trips.

A word of warning! DO NOT expect the auto-fill to absolve you of checking your batteries visually! My mechanic said most of the problem seems to be in the battery caps, which somehow preclude the water going everywhere it is supposed to go.

Net result is that I now have 6 new Trojan T105 house batteries, and I have installed a Flow-Rite 6V kit on each battery ($30/battery) at the suggestion of my mechanic. He says this should solve some of the battery caps preventing water from going everywhere when the auto-fill is used. He also said to be sure to visually check the batteries regularly anyhow.

This is not the first case of which I am aware where the auto-fill system did not work as it is supposed to. There is obviously a problem with the OEM combination of auto-fill and original batteries/caps.

Double check the operation of your system or you will have a very expensive experience!

We had/have the same problem as Rick Coleman. It seems, though, that our batteries did not ruin before the problem was discovered.

So, these automatic float systems cannot be counted on.

I had the same problem as Rick, but I went the more expensive route and installed AGM batteries.

Also, after service a while back, I went to add water to the old batteries using the fill system, only to find the solution in the reservoir was blue!!! The nice mechanic had filled the distilled reservoir with windshield washer fluid!!
