Integral Water Tank Part 2

200 hours later, we finished the water tank! Parts 1 (Building an Integral Water Tank) and 2 combined for a rewarding job; now we have double the water capacity (65 gallons), more storage, and an easy to clean cabin sole.

Installing 3 inspection ports
Using an angle grinder to recess the inspection port to stand less proud
Dry fit
Brew coat on the bottom of the sole/tank top
Brew coat (second coat)
Third and last coat

After finishing the brew coat (a food grade epoxy coating), we prepared to epoxy the forward sole section and the main cabin sole/tank top into position. We applied epoxy to the tops of the flange from the old cabin sole, and to the new floors and baffles in the water tank.

Yes!

We finished the project by filling and painting the border of our new sole. Our water system works great! Check out our galley post to see our bucket sink, foot pump, and water filter.

    1. We used one gallon of brew coat on the tank in 2015. We have since rebuilt the tank. The plywood did not hold up. This year, we rebuilt the tank with Coosa board. This time we used just over one gallon of brew coat again. The kit from SS Coatings comes in a 2 gallon amount, and we have split it with other cruisers both times that we’ve used it.
