New Holding Tank
for a few years we battled a bit of an order in the area of the holding tank. New hoses and a hefty dose of chemicals helped quite a bit. However, at the beginning of this year after a good inspection it was clear the tank was getting way past its prime. The difference with the new tank has been dramatic.
At first I looked into purchasing what is essentially a custom tank from OceanLink but I found the site very frustrating, it was expensive (I think around $250.00) and would take three weeks for delivery. I called the company and they were very nice but it was more than I wanted to spend and I needed the tank fairly soon.
I ended up purchasing a 35 gallon tank from The Tank Depot which worked out pretty well. The tank was $125.00, and I needed a conversion kit that cost another $35.00 because the way the tank was configured would not work for me. Thats essentially the difference between purchasing a custom tank and what here is essentially a stock item. They have quite a selection of sizes and shapes but they come stock where the hoses fit in.
So first step was to make the tank the way I needed it. You can see below where all the holes for the fittings were. The conversion kit gives you plugs for those. I will admit it was a bummer not to use those holes because they were threaded, and the holes I made for the conversion kit were not. But trying to use it as already configured would have been very hard.
You can see here the hole on the top is for the drain, and the other fixtures I already put in are for the inlet and vent.
This is what I mean about it being a bummer not using the original holes that were threaded, the conversion kit is a plastic fitting with a nut on the inside. Thus you goop it up with sealant, put it in and then crank the nut.
Here is the hole for the inspection port.
Here is the tank back in the boat, on ours its under a berth in the forward part of the boat, directly on the other side of the wall where the toilet is in the head.
Heres a picture of the drain hose in the bottom of the tank, it goes through the wall to the head, under the sink and into a through hull.
So far so good, one things for sure it is a big improvement and it completely eliminated the odors.
