O Day 272 plastiic water tank

My 20 gallon water tank has a horizonal split about a foot long near the top on what would be the side faceing the outside of the boat. I have removed the tank. any suggestions as to how to repair would be greatly appreciated.

plastic welding of cracks

Easy Fix. It's most likely a rotomolded or plastic welded tank. You can plastic weld the crack. Use a soldering iron if you don't a plastic welder. Try to get some donor material to puddle a weld fillet after you fuse the crack back together. Be aware the crack maybe a good indication the plastic has lost it's plastizers and is therefore old and brittle. Might be time for a new tank. Good luck.

How difficult was the tank to remove?

If it was difficult, you should probably replace it, rather than try and repair it, since many plastics do not take to repairing well and you'd likely be pulling the tank out again when the repair fails.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Epoxy will not stick to plastics like the tank. That is why all the tools for filleting epoxy are plastic - very easy to remove the epoxy after it sets.

Used this on my poly tank in my boat almost 3 yrs ago now.

Amazon.com: 3M(TM) Scotch-Weld(TM) Structural Plastic Adhesive DP8005, 35 mL [PRICE is per PACK]: Industrial & Scientific

It was over the top in performance! We would have had to rip the saloon settee apart to remove it though. If yours is out replace it for sure.
