Can you combine condensate lines?
“The condensate drains for both systems are jointed together. A clog in one line with affect both units and we therefore recommend, as is customary, two independent condensate drains. Service by a licensed HVAC contractor is recommended.”
How many condensate lines are there?
Primary and secondary lines Many units that are located in attics or similar places will have two condensate lines. One is the primary condensate line that is generally connected to a location, like a tail piece of a bathroom sink drain piece.
Can a drain line be sized to carry condensate?
Regarding the conditions inside the drain line, as there is no significant pressure drop between the plant and the trap, no flash steam is present in the pipe, and it can be sized to carry condensate only. When sizing the drain line, the following will need consideration:
What is a condensate line in a HVAC unit?
Enter: the condensate line. Your condensate line is essentially a drain line. It’s typically made out of plastic (commonly PVC) or sometimes metal, although plastic is preferable. It connects directly to the HVAC unit then leads outdoors, often through an exterior wall.
What does IMC 307.2.5 say about condensate drains?
IMC 307.2.5 states that the condensate assembly must be installed so that the drain line can be “cleared of blockages and maintained” without cutting the drain. The IMC states that condensate drains should be trapped according to manufacturers’ specs.
What are best practices for condensate removal on steam lines?
The following four “Best Practices” are guidelines to help ensure the smooth discharge of condensate on steam lines and to prevent the occurrence of typical steam system problems such water hammer and air binding.

Can a condensate line travel off the service platform?
If the condensate lines travel off the service platform and disappear in the insulation, that’s fine. But you still need to confirm to yourself that the ENTIRE drain line has at least, an eighth-inch slope to it. I’ve seen some pretty big dips in PVC piping which clogs the drain line, creates a backup, and causes water damage in the house.
