|In response to Re: Expansion Tanks|
The water in the expansion tank in the attic is warmer than the air surrounding it and therefore condenses the water molecules contained in moist air into dripping water.Several insulators can keep the air away, and several other insulators can keep the warmth in. Either one has to be absolutely airtight. You can build a styrofoam box (like a picnic cooler) to encase the entire expansion tank and its mounting hardware, and then caulk completely any area that allows the condensate return and supply lines, mounting lumber, or hardware to penetrate, and then caulk a lid into place. The trouble with this type of installation is that if you didn't do a good job of sealing, water will collect in the styrofoam box and will breed staphlococcous bacteria and mold spores, spreading staph infection. You could wrap the entire expansion tank in insulating rubber and use a high quality contact cement at the joints, making sure to also wrap the supply and condensate return lines wherever they are exposed to air, and custom fit the insulation at the fittings and unions by cutting gore points and scribed elbows.
Probably cheaper and a more homeowner type repair is to build a small drain pan and drain tube to allow the condensation to form and drip, and drain to a PVC pipe which penetrates the attic wall, (and of course gets caulked) and extends four inches past the siding, and is allowed to drip into a cute little bird house with bird waterer hanging off the eves.
