After all, there are small plumbing problems can be easily handled by a DIY aficionado. But there are just some things that you have to be really wary of. There may be some problems that you believe require a simple fix but they turn out to be just symptoms of an even bigger concern. Of course, you can always call Hayes Plumbing if you want answers to your concerns regarding your plumbing system.
Here are some common DIY plumbing mistakes that can actually escalate a problem:
USING THE WRONG TOOLS
Some people think it is okay to improvise when doing simple fixes. But the thing is, it can actually cause more problems. For example, shoving a metal coat hanger in your attempt to unclog a drain is a risk because if you lose it, there’s one more thing that you have to dig out.
USING TOO MUCH CHEMICALS
Okay. In some situations, chemicals might be beneficial, but do know that it’s not always the case. For instance, chemical drain products don’t actually work for most of the obstruction that causes clogging like toothpaste and soap film, as well as hair. What happens is that they create an even more complicated issue as they can damage your plumbing system. Also, chemicals are very harmful when you inhale them or when they come into contact with your skin.
KEEPING THE WATER ON
This is a no brainer, right? If your repair requires that the water is turned off, please do not take the risk. If you don’t, you can be in the middle of a strong stream of water that will be everywhere. And make no mistake, that’s going to take a while to clean up. Worse, it can cause water damage to your home, too.
DISASSEMBLING PIPES
If it’s just a clog that you’re trying to fix, do not take apart your pipes! We know there will be an urge to disassemble the structure, but try to resist. Doing so might help you find the clog, but putting the pipes together can be a nightmare, especially because it would require some special tools that only professional plumbers have and know how to use.
