How can a pool table get ruined?

Answer 1

A good slate pool table cannot get ruined in normal use - things get spilled or other damage occurs to felt. which simply gets replaced - the rail rubber deteriorates and has to get replaced - etc. By far the most common thing to hurt a pool table is people bumping into it, hard, or picking up an end for some reason, both of which now may require the pool table to be re-leveled. Most things that happen to a pool table like this are to be expected and simply part of owning a pool table - it requires maintenance at some point.
