I had a new high efficiency furnace installed and I'd like a second opinion on the way the drains were plumbed.
The installer ran a 3/4" PVC pipe from the AC condenser drain to a T that drains a trickle flow humidifier to a T that hooks to the furnace condensate pump to the sump/ floor drain.
My concern is that the humidifier creates chunks of minerals (I'm on a well system) which slew off into the drain occasionally. If those chunks block the pipe downstream of the furnace drain, it will shut down and I'll be without heat.
Should the humidifier have it's own drain line?
Thanks in advance for your help.
