Just got done emptying our waste tank, and now it sits in the back yard, as we are trying to clean it before reinstalling it. What a job!!! This tank is original equipment
...11 gals., 10 usable, installed in our 08 Larson Cabrio 260. We have a Dometic vacuflush head
. All grey water
is plumbed overboard
Originally, I planned on changing the tank to a larger tank as it seemed last season we were pumping out just about every weekend(two days usage). As far as usage goes, I use the marina head
almost exclusively, while my wife uses the head on the boat almost exclusively. We think that we are pumping out too often, and blamed it on the tank size at first, but I am wondering if we are not pumping out properly....I pumped the tank out at the end of the season(or thought I did) in anticipation of the winter. We spent extra time there to make sure we got everything, but I found this spring that we left the tank about half full!! Thank god it didn't burst over the winter!!!
Anyhow, since we were unsuccessful at the end of the season, I am wondering if we were not pumping the tank completely during the season as well, therefore possibly explaining the short cycles, if you will. This was our first year with this type of boat(cruiser), and much of the equipment
. The tank is a poly tank, but stained on the inside to not allow us to see the level so well. There is not a level meter other than warning and full float switches and lights.
After reading some articles here, I wonder if my vent filter was clogged, or something like that. We bought the boat used from a local dealer. Could the tank have been so filled with sludge, that that never came out? The gray water
was originally plumbed to empty into the tanks
as well.....I replumbed that last year, but the fitting at the tank was loose(and had been by virtue of the caulk buildup). Anyone have any suggestions or comments? How much waste does one human make per day? I read here someplace that it is an average of 6 liters (1.59 gals) per day, which should equate to us being able to go longer than we have. I can fit a slightly larger tank, but would just as soon not if I don't have to...
BTW, I boat on an inland lake in North America, so there is no option of pumping overboard
Thanks in advance.
