Hey guys looking for a little info here..I am the head of Maintenance for a big hotel chain in ohio..this is the problem we have 3 hot water heaters in one room all have expansion tanks...in april we noticed one of the expansion had a pin hole in it and was shooting water across the room...so we replaced it and just noticed today that the new expansion tank is leaking now. what would cause these to go bad so fast.The two other water heaters still have the original expansion tanks on them and both still look new. These water heaters are about 7 years old.....thanks in advance guys
