Quiet condensate pump for gas furnace
 

The house I just moved into has a closet furnace with a Hartell
KN-20X-1UL condensate pump. I can understand why they felt the need to
pump the water up to the attic and out the side. Finding a way for it
to drain would seem very difficult from the closet. Guess they could
have gone with an furnace installation in the attic but oh well.

However, the thing is noisy. Not so much while the AC is on but after
it's off since condensation can still drip into the pump for up to an
hour or more. At night this has a tendancy to be loud when no other
sound is made.

So I'm wondering if anybody has any advice to a quieter one. The
installer could have gone with a 15' unit instead. It doesn't have to
pump that high. Would a Hartell KN-15X-1UL naturally be quieter because
of this? Thanks.
