MMA (this stuff) hardens when exposed to sunlight. The tank and valves are outdoors. I would not be surprised to learn that is why the pipes/valves/etc are "gummed up" (to use the term from the article) - people who touch the valves/etc probably have mma on their hands/gloves, and then because those are outdoors, it eventually hardens. Or something similar. |
