Best Drain Cleaner For PVC Pipes

Clogs are a common occurrence in homes due to a wide variety of reasons. The vast majority of drain pipes found in a home are Plastics Polyvinyl Chloride (PVC) pipes. PVC pipes have several benefits like low cost, high-temperature resistance, fracture resistance, and strong joint tightness, which is why they are so commonly used in piping.

Unlike other types of piping, PVC pipes aren’t prone to corrosion. Regardless of that you still need to be careful when using drain cleaners since some can be quite damaging to PVC pipes. Here are some of the top recommendations when buying a drain cleaner for PVC pipes.

How To Unclog PVC Pipes

Depending on where the clogged PVC pipes are located, whether it’s the bathroom or kitchen, clogging can occur due to different debris buildup. You can tell you have clogged pipes if the water isn't draining or if the water pressure is low. If your water pressure is low, you might also want to consider investing in a water pressure booster pump.  

You will want to use a drain cleaner that can clear up different types of material, which you can find with any of the options listed above. For most drain cleaners the steps are similar. 

Pour the drain cleaner formula down the pipe that is clogged. Wait anywhere between 15 minutes to an hour depending on the formula and the instructions. You’ll often get the best results if you leave it on overnight.

Once it’s been on for a while, pour hot or boiling water down the drain. At this point, the clog should be gone, and it should work as if it was brand new, assuming you used a quality cleaner. 

If it’s still not fixed, then it might be time to bring out a drain snake. Most of the time, a clog forms in what is known as the p-trap of a pipe. The p-trap is the curved area of the pipe, and if there is a clog at this point you might see water trickling from here. 

First, place a bucket under the pipe and then loosen the nuts to remove the p-trap. If you see the clog, remove the materials with a drain snake or any other tool.

If no clog exists at this point, then just use your drain snake and run it down the drain until you hit the clog. Even if you use a drain snake, you will still want to use a drain cleaner to clean up any left debris.
