Well I guess I'll start with what I found out about the HVAC system when the boiler guy came a while ago. He cleaned the boiler, which is pretty new, and working great. I expected nothing less since the woman I bought it from had told me it was newer. Unfortunately I also found out about the second half of a boiler system called the heat pump. It pumps the hot water through the furnace inside of the boiler and up to the radiators throughout the building and back down. Fortunately the pipes seem to b in good working order, but the heat pump is on its way out. Some genius installed it so that water drips into the coupling of the heat pump motor and it has been slowly rusting. After every time the boiler cools down when it's not needed, a gasket contracts and some condensation drips straight onto it. It all could have been avoided if installed right, but now I'm left gambling that it'll make it through the winter. No sense fixing something that's not broken yet. For all I know it could last another 3 years; we'll see. sounds like a relatively quick fix when it goes as well.
Which brings me to the expansion tank. Yet another thing that my inspector failed to see. The pin hole leak that drips and rusts. It's been a real bitch to stop the leak so that I can patch it with some JB Weld. The trouble is that it won't set up properly unless it's dry around the hole. And being on the bottom of the tank it just keeps dripping despite turning off the value to it and waiting for it to drain. The vacuum created in the tank makes it drain slower and slower as it gets emptier so it takes forever.
I've tried soldering it but when you heat a tank of water the pressure pushes more water out. I've tried underwater JB weld (white); it's bullshit and doesn't cure fast enough to hold the water in the tank. In a last ditch effort I've put a bandaid with adhesive around it on and then covered it with JB Weld. Still haven't looked to see it it worked, but I'm hoping to cover the entire thing better with the JB Weld again if it stopped the water. Here's hoping...

The expansion tank is an easy fix if it is for your water heater. There were a lot of people having issues with their tanks in my condo and since the building installed all the same tanks I replaced mine as an insurance policy. I don't think a tank will be more than $50 at home depot and takes 15 minutes to replace. It would at least save you from having to spend the time to keep patching it.
