[Gold Digger]

I have one "A" with powder rust in it that gave me trouble for several years. I replaced the valve twice and pencil filter both times and still had fine rust go through and stop up my sediment bowl. i ran a magnet around in tank often and would find real fine rust on it every time. So I made a magnet with a hook in it and leave it in there for a year at a time. When I pull it out to clean it is always loaded with fine rust. Recently I was in Harbor Frieght and saw a pack of 4 magnets the right size with a hook already in them for $4. I almost bought them to have in case I buy another one with rust in the tank.
