If anyone could provide how or if this problem is corrected I'd really appreciate it. All the techs and installation company is clueless after contacting them, and I'm not interested in replacing the furnace as some have suggested. TIA.

dosy777: I'm not hijaking anything (?) I'm looking for the solution to the problem that started the thread. If the problem was solved, it would be great to see what the solution was. That's the point of these threads!

See my photo posted before, make the tube to go up (tie a hook in the top), so the drips of water go back into the motor. My furnace has been working fine for last 2 years! I have consulted the maker of the motor, this is ok.

Thanks Quin. It wasn't clear if that actually fixed the problem or not, but it's great to get confirmation that it did! I'm going to give this a try and keep my fingers crossed....

Are you still going with the vinyl tubing? Has it held up? Funny, your furnace looks exactly like mine, as well as the replacement combustion blower. Mine is a Fasco A172.

Thanks again.

My vinyl tubing is good, wind from the motor has cooled the temperature down.

Quin
Your solution was elegant.
I've seen a client do the same with a t fitting placed in the low dip of the tubing. The t fitting was attached to a hose that draped down into a large glass jar. The water in the jar sealed of the drain opening of the drain tube so the pressure switch could function. The glass jar in the furnace evaporated the liquid enough that he never needed to empty it. The only drawback was that he'd have to pour an inch of water into the jar at the begining of each heating season or the furnace wouldn't work.

Quin / rcisguyrcisguy, please confirm after the new routing of vinyl tube if you still need to drain the water out of preesure switch tube once in a while? my concern is if water flowing back to motor, it could cause damage to motor.
Your response will be highly appreciated.

Thanks,
