4300 Gallon Plywood Build (3600+ Take 2)

Dang, After all this reading, I thought I would see a completed project..

Ok that was a long read..

Anyhow, Pete... you get a major pat on the back for going this far..
Can't wait to see it done

Congrat's on the engagement

That's why you should always start at the END of a long thread and read back. :hitting:
 
A belated contrats to you and good luck with your tank- it seems like you deserve it all.:)
 
I think investing in a liner is a good move but before I would go that rout I would strenuously consider the possibility that something is structurally not quite right with the container portion since the sealer by all rights should have worked by now.

If you consider the container with sealer to be smooth enough with enough coverage to stop a leak, then that may mean there is a real possibility that somthing structurally is changing every time you fill the tank. If that tank is opening up here or there under stress, you could have a bigger problem then just basic sealing. I think the problem lies between the stationary structure of your home wall and the rest of the stand alone tank structure which may be acting differently on each when water pressure acts on them in opposite directions. It may be nothing more then a large settling or it may be a growing problem that may get bigger over time. Just a theory.:rolleyes:
 
I don't know at this point. I've thought about sheathing the inside with hardi board then sealing that, but I'm at a loss. The liner seems to be the most fool proof and cost effective.
 
I have an idea and want to see what you guys think.

Build a 2x4 frame

Cut a piece of liner to cover the acrylic (I have a section of old liner that may be big enough from one that had holes in it)

Secure the liner over the acrylic to seal it off from the rest of the tank

Test fill to see if it's the window seal causing the problem or not
