What does polishing have to do with cracking?
I wish you would of showed pictures of your plumbing and the crack, unless I missed it?
so sorry. Keep fighting the insurance company. Your home owners should cover damage.
Ive been in this hobby 30 years now.
The bulk head was hand tightened.
They forgot to drill the tank, so when i got there they rushed it.
The inside of the hole, including the edges had small chips and was not smooth.
The plumbing was stable and was not moving in anyway.
All these people crying wolf about that company. How many of YOU own their tanks? I personally do, going on 8yrs, and 4 drilled holes. No issues.
I'm sorry to say it...
#1- You over tightened it
OR
#2- You bumped the stand pipe.
I literally just cracked a 30gal last night. Luckily it was an old tank. But after 10+yrs of use on that one, why did it crack sitting on the ground empty. I BARELY backed up into it BARELY bumping it, I hit the bulkhead...BAM giant crack!
I'm glad you didn't lose your entire home. I'm glad you are safe. But, in all honesty, I don't buy the story...glass just doesn't break...

Pic of the tank and the hole would be helpful.
Possible failure mode, just conjecture: connect the bulkhead to an elbow, then a long piece of PVC pipe. The PVC pipe is a long lever whose fulcrum is the bulkhead fitting. Would not take much pull pressure on the end of the PVC to apply a *lot* of force to the hole edges.
Might be best to use barb fittings and vinyl tubing.
just post pic of the plumbing and did you support the plumbing behind the tank?

everyone seems a little harsh.
10 minutes of effort on google would give you an answer. It's well documented in the glass industry.What does polishing have to do with cracking?
