When using Chime tanks, are there any concerns with Joint Gasket Embrittlement and possible leaks?

Generally speaking, leakage caused by gasket embrittlement is rare. UV light will, over time, break down the gasket material. However, once installed, the “working” portion of the gasket is blocked from light exposure by the panels it is sealing.

This risk is further mitigated in western Canada as for most applications the tanks require insulation and cladding or are located in a building to prevent freezing.
