O Day 272 plastiic water tank

[Hagen]

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.

Replace it.

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.

tank is in and out in 10 min. thanks for info. has any one had luck with epoxy in this type of repair.

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.

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.
