i replaced my faulty holding tank indicator light last season and installed a snake river model that's a bit more tell-all. we've (my 10 yo, my wife and myself) now spent two weekends on the boat and i'm only up to 1/4 tank. so of course i'm wondering if the thing is working correctly so i tried to figure out how much liquid goes down with each vacuuflush. here's what i came up with.
i emptied a 1/2 liter water bottle into the DRY bowl. the water level that created looked about the same as the level that we will typically flush (yellow let it mellow, brown flush it down). my holding tank has a 20 gallon capacity. yes i know, small. but this was confirmed by searay AND by measuring the volume of the tank in cubic inches and converting it to gallons (LxWxH=4600cu in=20gallons). i have not (nor do i intend to) keep a running total on the flushes.
anyway, 20 gallons = 75.71 liters, which means it'd take 150 such flushes to fill the tank. assuming that SOME of the flushes contain MORE than a 1/2 liter, i figure a flush total greater than 100 would be entering the danger zone. so if the 1/4 tank reading given by the snake river gauge is correct, i've got 25-40 flushes sloshing around in there.
anyone else wacky or gross enough to think about/calculate this??
