We discovered that the "drip pan" that was holding up the PWET (potable water expansion tank) was entirely rusted and had disconnected from the drain spout. More than one of the metal strips holding the drip pan to the beams in the attic had rusted through and had broken loose.
So, here are some Before, During and After photos of our exciting Saturday morning home repair adventure.
As you can see here the 'drip pan' is tipped forward, away from the existing drain spout.
Sorry for the rotated angle, however it shows just how far away the drip pan was from the drain spout!
The outside of the Potable Water Expansion Tank had to be cleaned off and inspected for any damage or cracking...
The original drip pan caked with layers of rust...!
We had to get creative in our repair as Lowe's doesn't carry or even know of any small (12"x12") drip pans with drain spouts. So, we used a plastic storage box and a 1/2" wood bit and made our own hole.
We independently suspended the PWET to hold it up out of the drainage container. We then positioned the plastic drainage container and used liquid nails to attach and seal the hole in the box to the existing draining spout.
We'll have to check on the seal after the glue has seasoned overnight. We had to remove some insulation from the attic and treat several wet boards. There is no mold or mildew but I'm just overly concerned with such possibilities. My super-sniffer has not picked up on any indication that there is a growth in the boards up there.
We thought we were out of the woods, so to speak, upon completion of this project. However, when Dan went outside to turn the water back on, the pressure jolted the pipes and I then noticed a small drip on ANOTHER pipe connection. You cannot really see the small pool of water around the base of this connection.
The leak is where the copper piping meets the plastic ring...there is evidence of rusting in the copper pipe. I thought copper was sturdier than this! The house is 7 years old! I'd expect pipe degradation in an older home but not here!
