Thankfully my house has been OK, but the AC is only a year old, so I would hope so. Now I will share my own experiences with this joyous subject! sorry its going to be long. I dare you to open that up, its going to be NASTY, I can tell because that ugly brown/yellow tube from the pump, it probably started out as clear tubing, and has algae in it.Īlso, you might want to re-evaluate the idea of not needing primer, it will be under a light vacuum pressure, and the drain in my parent’s house separated right where it attaches to the condensate pan, causing a fun leak. Its not just for the trap, its for the condensate pump as well. you want to flush MORE bleach than just a teaspoon through the system, like a quarter cup in a gallon of water (pour that through, then flush it with another gallon of clean water to make sure the bleach doesn’t sit). I see most of my comments have already been covered, like the purpose for the removable cap that you already figured out 🙂 when you used it to flush the system.īut I do have something else to add to that. Have you ever had to tackle and issue with your HVAC unit? Do you remember to change your air filters? What have you made out of PVC before? Fred and Kim have their A/C back and I get to share a great how-to with all of you. When it was all finished, we flushed the line with water to make sure it didn’t leak and everything worked as expected. Here’s a close-up of the bracket I used to keep the PVC in the right spot. I actually ended up gluing the left side of the flexible tubing (in addition to the metal clamp) as there was a small leak. Turning that screw allows you to tighten or loosen the clamp. This is the metal clamp I used to secure the flexible tubing. Keep everything in the right orientation, otherwise you’ll end up with PVC going in the wrong direction. It’s also a good idea to give it a little twist to ensure good coverage. PVC cement is a chemical solvent that melts the two pieces together making a super strong bond when it cures.īe sure to fully seat the PVC inside the fitting. When I was satisfied that everything fit together, it was time to start gluing. We had a miter saw handy and it worked well. If you’ve ever worked with PVC before, you know that it’s important to make clean, straight cuts and to remove any burrs and debris. I’m not sure if it was to introduce some air or another reason, but I recreated that too. Using the old drain as my template, I began dry fitting everything together. Here’s a picture of the existing PVC. The drain goes to a small pump. Since this was a drain line and wouldn’t be under pressure, I didn’t need to use any PVC primer (that purple stain you often see on PVC). I had a gift card for Lowe’s so that’s where I picked up my supplies - ¾” PVC, various fittings, 1′ of clear tubing, a pack of metal clamps (the kind you tighten with a screw driver) and PVC cement. The trap would collect any gunk, and adjustable clamps would allow access for cleaning. My goal was to piece together a new drain line and use some clear flexible tubing to recreate the trap.

How to Replace an Air Conditioning Drain Line You can do this project too, if you find your air conditioner giving out due to a condensation line clog. Unfortunately, none of the big box stores carry that component, so I improvised.

I thought it should be simple enough to install one at Fred’s and Kim’s house. When my HVAC unit was replaced, the pros installed a clear plastic trap so we can see when it needs to be cleaned. It’s a better solution than having interior temperatures reach 90°, but it wasn’t a permanent solution. Water pooling inside the drain pan of the air handler was preventing the coils from cooling down, ultimately robbing cold air from the rest of the house.įred took a temporary measure and cut the drain pipe, then directed the water into a bucket which had to be emptied every 12 hours.

They went home and checked, and sure enough, found their drain line full of dust, rust, and other gunk.
The Fauth family came to our place to cool off that night, and I told Fred and Kim how a while back our HVAC quit working because the condensation drain was clogged. Remember those kitchen cabinet pulls I installed at Fred and Kim’s house? Did I mention that their air conditioning wasn’t working that day… and that it was 100° outside when I did those? I didn’t? Well, it was miserable.
