so 2 days ago i took a road trip to morgantown, wv to pick up a new piece from cool ridge. i ended up picking out a beautiful ~30" double dome perc bubble bottom bong with ice notches. i didn't really notice in the store, but when i got home i saw a tiny crack in the joint, just barely noticeable. i called up cool ridge the next day, and the girl said that all water pipe sales are final, and that they could not do anything about it. today i looked at the bong, and the crack had spread all the way from the top to the bottom of the joint and down and slightly around the top of the bubble bottom. it still hit fine, but i didn't want the crack to spread more. i have since repaired it as best i can with hot glue, which doesn't look as bad as i thought it would. in fact, if the hot glue is the right solution, i would be fine with leaving it like that. but my question is: will the hot glue prevent the crack from spreading? if not, what should my next course of action be? i know joints can be repaired, but the crack extends well into the bubble bottom. would it be better to have a blower convert it to a straight tube? is that even possible? i would prefer to leave it with the hot glue, but if that won't work, i want to find the best way possibble to ensure that i didn't waste $202. thank you in advance for your help. sorry i don't have any pics.
