retro-fit water tank inspection hatch?
Has anyone installed any kind of inspection hatch on an aluminum tank?
We recently purchased a Nordic Tug 37, which has a built-in aluminum water tank. Unlike the rest of the boat, which is immaculate, the water tank has been sorely neglected. (Wish we'd noticed this on the survey.) The pump strainer keeps clogging with what can best be described as black and grey snot. I suspect I could fill and drain it forever and not get all this stuff out. What I need is access to the inside - ideally, from the side as there's not much overhead clearance.
