Merging multiple plumbing lines in a furnace room
First I would like to say Hi and I apologize for any incorrect terminology used.
A little background:
My fiancee and I built a house and recently took possession. We have been living in the house for about a month now.
Please see image for clarification.
In our furnace room, there are currently 4 water outlets all draining into the same area:
1. Red - Slightly acidic water coming from on demand heater. Seems to be some soft rubber tubing
2. Blue - Clear plastic rubber/plastic tubing from the Air Exchanger
3. Purple - white pvc piping from the furnace (it was have an atmospheric vent)
4. Green - same clear tubing as Air exchanger for Humidifier
I was wondering, would it be ok to merge all of these lines into the furnace's PVC Piping in order to clean up all the lines?
I don't personally think there would be an issue as long as the angles of the new PVC piping is correct and it is vented.
Can anyone provide me any feedback on this?
