I'm trying to figure out the best way to modify my PVC condensate drain so I can clean it out properly. It's currently clogged, and I can't seem to get my wire pipe cleaner through the first elbow. The opening is only an inch or two wide, making it tricky to work with. I've been using a 30% vinegar solution to clear the line, but it only offers a temporary fix; it gets clogged again shortly after. The drain is connected to my gas-fired furnace, which I worry might complicate things regarding carbon monoxide hazards. I'm new to cutting and gluing PVC, so I'm looking for straightforward modifications. Would switching to a clear plastic hose be helpful for future clogs? I'm aiming for the simplest solution since I plan to replace this unit in the next five years. Thanks for any advice!

You might need to cut the drain line a couple of inches from the pan for easier access. Just dry fit a couple of new pieces back on without gluing—it's straightforward and won't have any pressure issues. Additionally, consider leveling the back end with some wedges to help drainage. If you're feeling adventurous, try adding a slip joint; it'll allow for easy disassembly later and still keep it sealed.
Consider using a shop vac to clear out the clog. It might give you the extra suction you need to remove blockages from the drain. It’s often pretty effective for cleaning out pipes.
But honestly, dry fitting could lead to leaks down the line. Glued joints might be the way to go unless you can ensure a perfect fit all season!
