So, we drive up to the marina today to pull out the old nasty holding tank on Emmanuel. when we arrive I am pleased to see that our new tank from Triple M has arrived and is waiting for us. Captain Grumpy gets to work pulling up the cabin sole and working on removing the fittings from the tank. The smell is pretty bad but manageable. We get the fittings removed and the bolts unscrewed from the hold down flanges and now the smell is really bad. We decide it is now time to lift the tank out. We both grab hold and lift and we realize that the tank is full!!! A 40 gallon aluminum holding tank and it's full of black water!!! We were horrified. The worst part is that because of the moving around some of that nasty water has sloshed out and then makes it's way to the bilge, which because of the automatic pump, it kicks on and then we're pumping that stuff right out onto the parking lot. It was awful. It turns out that the previous owner had arranged for the marina to do the winterizing on the boat and they didn't pump the holding tank!! All they did was throw some pink stuff in the heads and pumped it into the tank. It was truly disgusting.
