We took Trixie out for the first trip (little red 176S) We had filled the fresh water tank as we were staying at a hot springs with sulfur water.  The weird thing, we ran out of water in 3 days...we only used water to do dishes 3 times, make coffee and oatmeal and use the toilet...no showers. It says the tank is 39 gallons...but when it was empty, the black tank was empty and the grey tank was only 1/3 full....it sure didn't seem like we went thru 39 gallons of water.  When we filled up, the display showed the tank was full...but it sure feels more like 11 or 12 gallons used. Are there tricks I'm missing? 20170526_154205.jpg

Did you run out in that no water came from the faucet, or did the display just show empty? If the latter, could just be an issue with the display.

Sure way to tell is look at the tank underneath - I assume it's translucent white like on the 177, so you can see the water level.

There's also a short hose with a plug on the end for draining, the hose itself might not be screwed into the tank tightly, or the plug may be loose - you could lose water that way. Worst case is a plumbing leak, hopefully not inside (but you'd probably notice water on the floor if so). Fill it with water in your driveway, and check for wet spots after a few hours.

We actually ran out...when my husband looked underneath he said it looked like there was about an inch of water in the tank. We will check the drain hose and see if that's the issue, thank you for the suggestions.

We ran into the same thing, we were a bit mistified. I called our dealer's repair shop and asked why this might be. He explained that the hot water heater fills with water as it is used. The heater tank holds 5 gal so it diesnt take long for the water to get used up. I have noticed if no water comes out when the cold water lever is turned you can turn on the warm water lever and there is water because it's coming from the hot water tank. After we thought about this we could see how the water was being consumed so quickly. Once we adjusted for it we didn't run out of water unexpectedly. I have found the gauges aren't very accurate for fresh, black or gray water. Not sure if this is helpful but thought I would offer it up.

Georgiana Rock, thank you. I didn't think about the hot water tank holding 5 gallons. This helps. I guess I just thought 39 (or 34 gallons if 5 is in my hot water heater) would go further.
