Plastimo tank leaking again

[KAM]

Just had another one leak after less than a year. Probably my 4th in the time I've had the boat. Just fitting a replacement. I pumped it up with air in an attempt to try to get all the creases out of the corners. It doesent seem possible as the outer is smaller than the inner. By the time it's filled with 200 litres of water I don't see how it's going to last very long again with all the creases in the corners. The hull is designed for this type if tank and is very smooth. They always fail in the same way from a small split near one of the corners. Any good ideas out there to increase the life.

There are a lot of threads on Plastimo water tanks leaking. Have you read those?

I replaced my leaky Plastimo tank with one from Nuovo Rade. Single layer fully welded and seems to be made of the same sort of material as inflatable dinghies.
I've been very impressed so far (c. 2 years); seems very robust and no plasticky taste.

Is it always the same corner? May not be the tank that is the problem! Could it be snagging on something, or is that too obvious?

The boat was designed For flexi tanks. The compartment is very smooth. Leakage is from nicks where there are unavoidable folds in the corners. Think I'll maybe limit to half full and go for rigid tanks in the future.

I have had a Vetus flexible tank for black water that has lasted 12 years with no issues. Other brands I've used for fresh water have seldom lasted more than a year.
