It's not that hard to do, about an hour job or so, just get a friend to help you with the lifting if you don't have access to a lot of tools, like floor jack, pliers, screw driver, drain pan, hammer, just take off you filler hose by turning it to break it loose after taking hose clamps off,drain tank if full, undo the two straps (skid plate)with a socket and rachet, holding tank up, lower it down a little, take off your vent line, return line, high pressure line, drop it out pulling the wire appart at the couplers by hand, when out turn the ring at the top or unscrew the top plate(would have to go look at mine)pull the pump out and see what is in there! you might be supprised at what the kiddies will do to pizza guys.olives ect.lol
