How to Clean Drain in a York Diamond 80

DO NOT cut any copper lines!!!!! You want to cut the 3/4 inch white plastic drain line and add a Y style fitting or a TEE fitting if a Y is not available. Then you can blow the line out with compressed air or what have you that will get the job done. (I use a small tank of Nitrogen but that is not always available to home owners)

After you clear the line you can install a small piece of pipe and place a cap on top so your future cleanings will be easier. This should have all been done during the install.

you can also find the drain outside and hook up your shop vac there and prime it to a good suction if you want. that will work in a pinch but hvac1000 is right there should be a nice p trap and somewhere to access but the shop vac will get you done in a pinch.

Thanks for your help! I agree the builder cut a lot of corners. I assume its not that hard to cut a pipe and install a Tee or Y style fitting (I'll check the internet). I assume this should be done away from the unit. When I cut the pipe I assume there will be a large flow of water from the unit which I should be ready for....the unit is in the attic. Also, before I cut the pipe I will open the valve per the caution sign. I assume it will re-pressurize after I close everything back up.

Thanks. Unfortunately, I cannot locate the drain outside of the townhome. The pipe goes from the unit into the floor of the attic and then disappears. As you can imagine, a townhome is not huge and I searched every inch of the outside and there was no pipe to be found. I am at a loss as to where the pipe goes.

then in a pinch just cut the pvc a ways away from the air handler and get a 3/4 coupling and some glue ready. vac it out to remove the obstruction and re attach with the coupler
