Copper Cylinder lifespan

    I replaced my copper cylinder 9 years ago but have had to get a plumber in this week as the feed and expansion tank in the attic was overflowing. He tells me this is caused by a pinhole in a coil in the copper cylinder which is pushing water up into the tank and causing it to overflow.

    Anyway, my question really is how long should a copper cylinder last. Nine years seems a very short life time. Also I am wondering would my house insurance cover the cost, I know it's not accidental damage but it is hardly wear and tear.

    Any advice would be appreciated.

    To answer your main question; lifespan varies greatly with type of water. Lots of people would consider 9 years great. Others would be getting a lot longer.

    Second part of your post. Is your domestic hot water tank in your attic higher than your F&E tank?. If not, it is hard to understand the over flow. Are you sure that it is not the big tank that is overflowing?

    Thanks for your reply. After I replaced the cylinder the last time I got a water softener installed as I live in a hard water area and I thought that might have contributed to the first cylinder having to be replaced and that one was also only seven years old.

    The big tank in the attic is higher than the smaller one and i have been keeping an eye on where the water is coming into the small tank from and its definitely not from either of the two hockey stick shaped copper pipes over the small tank so it must be coming in from a pipe to the side. The ball cock float seems to be working ok too as initially I thought that might need adjusting or replacing.

    Pin hole in cylinder coil may be correct diognosis then. Ask your plumber his opinion about using a cylinder of a different material.
