I always took my home's heating and cooling system for granted. That is until I found myself battling one of the hottest days in years and my air conditioner simply refused to turn on. After contacting my local HVAC contractor, I learned that my cooling coils had frozen over from a lack of maintenance. He did get my AC back up and running that day, but he also helped me to look at my heating and cooling system in a whole new light. I have spent a lot of time over the last few years learning more about how to properly maintain my HVAC system and ultimately lower my energy costs. Today, I would like to share this knowledge with you so that I can help you to avoid some of the costly mistakes I have made in the past.
Have you ever cooked a large pot of pasta and decided to strain out the noodles by pouring that boiling water into a strainer over your kitchen sink? You may think this is a perfectly fine thing to do, but it can cause problems with certain types of kitchen plumbing: more specifically, PVC piping that is low-quality or very thin. Here is what you need to know about pouring that boiling water into the drain.
PVC Pipe Heat Tolerance
In normal circumstances, PVC pipes can withstand heat up to approximately 140°F. Of course, this is when the liquid in the pipe is sustained at that temperature for a long period of time. Boiling water tends to pass through a pipe very quickly, and is unlikely to melt the PVC material. Boiling water also tends to cool down quickly.
However, kitchen sinks have a trap underneath them to stop sewer gases from coming up through the plumbing. As a result, it is possible for that boiling water to sit in the trap longer than necessary. Water can also get stuck in a pipe if there is a clog inside that you cannot see. This can cause that boiling water to sit in the pipe longer than normal, which can cause it to deform and weaken your plumbing over time. This puts the risk of having the pipe fail much higher.
PVC Pipe Protection
There are things you can do to help maintain your PVC pipes if you do pour boiling water down your drains. The easiest way is to run cold water as you are pouring the boiling water, which should cool down the temperature enough to avoid shocking the pipes with heat. You can also keep your kitchen pipes unclogged so that the water doesn't sit in the pipes. This will involve performing some regular maintenance, such as snaking a kitchen drain if food waste often goes down it.
PVC Pipe Replacement
If you have caused damage to your PVC plumbing, consider having a plumbing maintenance professional repair it for you before the pipe finally bursts. This will help avoid a messy accident where water spills all over your kitchen cabinets and floor.
As for replacement options, you can replace the old PVC with new pipes, and be more careful about how you drain boiling water. You can also switch your kitchen sink plumbing to metal pipes that will not warp under the extreme heat.Share
