OK. Help me give myself a bit of peace of mind WRT my recently burst sump.
Some history: this is a W/D I built about a month ago for my 200gal DIY plywood tank. It was built as an improvement on the original plywood sump, and was (I thought) a pretty nice piece of work. I filled it outside and let it sit for a few days with no leaks before installing it in the house. Well, long story short, it started leaking after about a month, and when I took it outside to figure out why - both bottom seams had blown out along the long sides.
I've used weld-on #16 to re-attach the broken joints, and I've used 7/16" acrylic strips fastened with weld-on #16 to the inside of the seams. (original construction was done with methyl chloride, so I'm avoiding that for the repair). I would also like to run a bead of some kind of sealant along all seams, so that even stress-induced seperations won't result in water on the floor. I'm considering silicone, GOOP, loctite marine construction adhesive, or anything else you guys might suggest.
I noticed that weld-on makes a two part high strength structural plastic adhesive. Is that the recommended compound for making tanks with? Should I get some to put in the seams?
Anyone offer some suggestions? The thing that really wiggs me out is just that the seam was perfect-looking in the beginning, and then it seperated. I really don't want to pat myself on the back fo rmaking a nice repair, throw it back into service and have to face the ol' lady with another 50gallons of water on the floor.
