What problems would this pose?

This is a condensation line, went from 1" pvc to 1/2 clear hose.. Any comments welcome.

The fact that the connection appears to be held together with black duct tape might be your first clue.

Yep thats the obvious one, what about the size reduction? Concern?

If you notice that many condensate drains in basements reduce to this size to reach floor drains, it is not likely an issue in and of itself. The level of flow through that line wouldn't likely need larger size.

I would be more concerned about the connection and where the drain ends up.

M1411.3.2 Drain pipe materials and sizes.
Components of the condensate disposal system shall be cast iron, galvanized steel, copper, polybutylene, polyethylene, ABS, CPVC or VC pipe or tubing. All components shall be selected for the pressure and temperature rating of the installation. Condensate waste and drain line size shall be not less than 3/4-inch (91mm) internal diameter and shall not decrease in size from the drain pan connection to the place of condensate disposal.
Where the drain pipes from more than one unit are manifolded together for condensate drainage, the pipe or tubing shall be sized in accordance with an approved method. All horizontal sections of drain piping shall be installed in uniform alignment at a uniform slope.


Obviously it does not meet the 3/4" requirement and should not be decreasing. The line also appears to be sloping up slightly. The main issue, besides the great tape job, would be leaking at that joint and blockage from either foreign items being washed down the tube or any buildup that may occur which would further reduce its size.

Already been said but anytime you put a smaller diameter hose, pipe etc. inside a larger one you create a lip or ledge inside the hose. This is a primo location for debris (rust, scale, funk, etc.) to accumulate and create blockage which is the last thing in this world you want on a condensate drain line.

What is the direction of flow?

Besides the tape job. Will the line hold water and freeze in the winter?

Around here there are many AC coils in the basement which means a condensate pump is needed to get it out to drain level. The pumps have a 1/2 inch or less poly soft hose to run outside or whereever. 3/4"? Couldn’t even fit that on these. Must be a provision for pumps.

What is important is the size of the drain line before it gets to the pump. Once the water is in the tank of the condensate pump, then the proper line size is whatever will connect to the pump, usually 1/2".
