Plumbing repairs are an aspect that almost all of us (well...maybe men) like to think we can do ourselves. And that's probably true for a lot of things. A running toilet is fairly easy to diagnose, and provides plenty of ways to get cheap parts for replacements. And in today's age, you can Google and YouTube basically anything to figure out how to DIY.
But sometimes you're going to need to know more than just some basic plumbing skills. And if you're not 100% sure then there's a 100% chance of making a mistake.
The most common aspect that we have found from our plumber Allen TX sources, is homeowners overtightening connections to the pipes. It's pretty easy to do, and sometimes you don't even realize you're doing it. Some of the fittings and other parts we use will be plastic, so overtightening plastic fittings on your faucet tubes for example can eventually crack and begin to leak. Same with toilets, being made of porcelain you're risking cracking that could destroy the toilet all together.
One thing that a lot of DIYers do first...is reach for the liquid drain cleaner. It's the easiest way to "attempt" to unclog a pipe, but not always the best. Too much liquid drain cleaner, being corrosive, can cause damage to the metal pipes and traps. Or, just think about how much drain cleaner is down in the P-trap if you have to take it apart?
Oh, don't forget...TURN OFF THE WATER! It's important to remember to turn the water off before attempting to replace any valves or pipes. It seems self explanatory...but it happens.
Long story short, think twice about the issue. If you have experience and know how to resolve a simple plumbing issue...then by all means do it. But consider consulting a professional first, even if it's just online research to see if it's best to try to do it yourself. If there's any hesitation, contact a local plumber and get a quote!
