I have a new Goodman GMH95 furnace, installed several months ago.
Recently I noticed some water pooling around the base of the exhaust
Hope this description makes sense. The PVC piping coming from the
outside fits into a PVC collar which in turn appears to be attached to
a flat plate. The plate is bolted to the top of the furnace with four
screws. I wiped away the water and watched more water slowly appear
as if it was coming out from between the collar and the plate. The
furnace wasn't running at the time.
The plate screws have rusted enough that I can tell this has been
going on for a while. There isn't any evidence of the water coming
from the outside of the pipe.
Any ideas as to what could be causing this ... maybe a sealant just
needs to be applied? I'm guessing that if I apply the sealant myself,
I'll be voiding the warranty.
Thanks in advance.
