Sorry for not getting back sooner but I wanted to make a trip and make sure my repair was sound. My spin weld guy flaked out on me so I contacted a RV dealer near by that was recommended and he welded it for me. $200! I wanted a new tank but I guess they repair them all the time as some had advised me here.Little pricey but what isn't these days?
Thank you for the help!
the vast majority of plastic fresh water tanks are a material that is easy and best fixed by spin welding. Holds up great. In fact in these tanks most of the fitting that aren't molded in are spin welded at the factory. Most repair shops that do spin weld repair have an assortment of spin weld patches on hand. Basically the patch or fitting is spun against the tank and friction melts the junction, stop, let it cool and it's welded together.
For black/grey tanks, most are ABS which again is easy to fix, but instead of spin welding, solvent welding is done. Basically either use ABS glue on small cracks or use abs sheet material to bridge the break and solvent weld.
