W.W. Fresh water tank problem

[sjseng]

My '05 LE 3305 W.W. has two fresh water tanks that I guess are supposed to self equalize. Well my problem is with the level gauge. At first, the water always seems to be used up faster than I expected.

I just recently drained the system after the winter. The water level gauge read empty. However, it still drained out of the mass dump valve for several minutes. When I filled it back up, it again took several minutes before the gauge began to read again. Once it started registering, it filled up very quickly and began to overflow.

It appears the gauge reads out of only one tank and it does not self equalize very quickly. Is this typical with Weekend Warrior? How do I fix this? I don't want to just assume that when the gauge hits empty that I still have half a capacity. What happens on the one time that it works right and I DO run out of water? Thanks for your help.

I thought that I would add this bit of info also.

It's not that the gauge responds slowly, but that it only works for half of the tank. I agree, I don't usually look at the gauge either when filling. When it overflows, it's full. Easy enough!

The problem that I have is it only reads the first half of the tank. From Full to 3/4, 1/2, 1/4, then empty. Only now do I know that I still have a half a tank left. But for the next few days, I have no clue. All of this while it still reads empty. I don't want to be at say Dumont were there is no water in sight, and run out unknowingly. Hope that makes since.

I need a way to have the gauge read the whole tank capacity, not just the first half.

Maybe your guage needs to be calibrated.

On our MH there is a little set screw below the fresh water tank button, covered buy a rubber plug. You may have the same . You can then set the guage to read full when full, and then set it again for empty.

[sjseng]

Are you talking about a mechanical gauge? I looked at mine and it is electronic with the lights on a circuit board with all the other gauges. No way to adjust. I think it may be because the sensors are on the elivated end of the tank. Elivated so the water will go to the pick up tube for the water pump. Not sure.

[Tom and Patty]

The adjustment is on our fresh, grey, and black tank panel, in the coach. I have seperate ajdustment screws for all three tanks. Each adjusting screw is under each button.

I don't believe there is any sort of adjustment you can make on the WW. As sjseng said, our tanks just have electrodes protruding through the tank. When the liquid shorts across them it lights them up.

sj-even if your tanks are equalizing slow, they should be able to equalize fast enough with normal use. I have never run out of water so I can't comment on how much is left when empty but
if you stick your head under there you can see how far down the last electrodes are. I believe on mine they are at 1/3, 2/3 and full. So once you have below 1/3 it will read empty. At that point it should be normal to have 20 or 30 gallons of water.

In case you haven't noticed, when the tanks have been filled they bulge down in the bottom and after that it takes about 10-15 gallon in them before the water pump will pick up the water so in effect when empty you will still have the 10-15 gal left in the tanks that will drain when you open the valve. Some have put additional supports under them but as I understand you have to be careful when filling or you could damage the flooring with the tanks bulging upward instead of downward. Thats all heresay though, no experience since I just left mine alone.

Also, these tanks are so narrow that the slightest thing makes the sensor read wrong. For example, parking on uneven ground. I only came close to running out of water once, at Pismo with a trailer that only held 50 gallons, 150 gallons is a lot of water, I never even come close anymore. If fact, I have only filled mine up all the way one time just to make sure it didn't leak.

My DW takes them as Gospel- I trust those indicators just about as far as I can throw the [Full] water tanks...

[Tom and Patty]

When I want a real accurate reading, I climb into the basement look up at the 3/4, 1/2, and 1/4 marks I've made on the tank. Never has failed . I know, I'm in a Toyhauler forum .

Someone has to spy on you guys and gals with all the toys

[sjseng]

Does this mean that your tanks are clear? My tank is thick black plastic. I can't see the water level even if I was to put a light up to it.

[Tom and Patty]

The fresh water tank is milky whte plastic. So I can see the water level. Even better with a flashlight. Since it is a rectangle, I measured the height and marked it accordingly. Black and grey are black like yours.
