We purchased our boat last April, and during the delivery
, our captain
said that he found the water tanks
were compromised by diesel fuel
from the bilge
entering the inspection
access caps on the tank. There are two of these, made from plywood
of all things, and the tank is 100 gallons capacity located in the top of the keel
, so basically the lowest part of the boat's bilge
area is above the tops of the tank. After discovering the problem, he emptied, rinsed and refilled the tanks
twice, and did a temporary resealing of the one hatch
that was accessible--the other hatch
is under settee floorboards so was not attempted at the time.
We used the boat all season and tried to flush out the tanks twice, but the diesel
is still quite prevalent. Our surveyor
said we should file an insurance
claim. we mainly just want to solve the problem to the extent of being able to wash dishes safely and take showers without smelling diesel. We don't plan to use it for drinking at any rate.
What I am wondering is if there is a suitable cleaning
agent to flush out the lines and the tanks to make it tolerable? After that, is there a membrane that we could paint
a new liner on the inside of the tank to make it more pure? I know we have to make new hatch covers first and get that sealed before anything else so no need to advise on that. I have looked into getting a bladder but have not found any that are close to 100 gallons, so would it be feasible to use 2 or 3 of these and somehow connect them if that is the route
Lastly, is the whole system permanently compromised to the point where we would need new lines, faucets, etc. or can that be flushed?
Thanks ahead for the advice.
