I haven't flushed my gas water heater since I moved into our home. We do have hard water and it's not that difficult of a process to do but now I'm wondering if I should even bother with it. If it doesn't make much of a difference then I won't do it but if it doesn't hurt to do it but may not help then I might as well do it. Terrell - I'm in need for an ~link deleted~ specialist
