Question about Aprilaire 700 Humidifier
I have an Aprilaire 760 attached to my furnace, but it just started to leak quite a bit of water from the bottom of the unit. It leaked a considerable amount of water before I noticed the problem. I have since unplugged the humidifier and it seems to have stopped the dripping. Is there a solution you could recommend, or should I just leave it unplugged? Thanks for any help...
The tune up kit that I ordered arrived on Friday and I installed most of it on Friday night. While it is nice to have a new frame and the distribution panel and I think the price of the whole kit was fair considering it comes with the parts and 2 water panels, the fix was really simple.
The kit came with the water distribution tube with with a new blue orifice (Aprilaire #4232) already inserted. This orifice is in the end of the plastic tube at the solenoid end. When I removed the old water distribution tube, the old orifice was not really dark blue anymore but kind of a light blue and was deteriorating from 12 years of exposure to the chemicals in the water. What should have been a pin-hole size opening in the orifice was up to about 2mm or a little more so the orifice was letting way too much water through.
If anyone else has this leaking problem, and your orifice is several years old, I would check that first. It is a $2.75 part and may be the cause of the leak. The whole feed tube kit is only $8.75 and includes the feed tube, nozzle, orifice, ferule, compression nut, strainer so if you need to replace the orifice, I would order the whole feed tube kit for a little bit more.
Hope this helps,

After shutting down my 760 for the summer, I recently turned it on and it started leaking water from the bottom.. This is the first time I've had this problem. The unit is several years old and I average a filter change every two years. I took the unit apart and made sure all the drain components were secure in their proper discharges. This fixed some of the problem. I then noticed that the fan housing was not aligned all the way with the housing on the furnace. After correcting this, no leaks.
