Anyone have any ideas why my side arm would stop working? To start off I have bled water from the bottom of the tank several times now. There was some lime but did seem like a ton of it. I have somewhat hard water (we do not have a water softner thought) so I know to do this on a reg. basis. Usually when the water isn't as warm as normal I know to bleed some off to clear things out. Well bleeding did not work this time, so I thought maybe something was stuck so I hooked up my compressor and shot air in from the drain valve (I closed the cold water coming in and open one hot water tap) and that didn't help. Also bled off some water from the P&T valve thinking maybe the blockage was at the top. We do not have a mixing valve (yes I know danger, by it's just me and my wife so we know...) so that is not the problem. Any ideas thoughts? Do not want to cut it off unless I have to as you can imagine. Thanks.
