It is not uncommon for people to attempt fixing plumbing issues without calling a professional. DIY repairs can be effective if you have the right tools and knowledge but they can also go horribly wrong. If you are attempting to make a plumbing repair yourself, avoid these DIY plumbing mistakes.
Rushing the Process
Whether it is a burst pipe or a leaking faucet, it can be extremely frustrating and disruptive in your home. People attempting to make a repair themselves are likely to rush the process, wanting to fix the issue as quickly as possible. Unfortunately, rushing can lead to careless mistakes that cause more problems.
One common result of rushing a repair is forgetting to turn the water off before starting. Even if you are not sure that you need to turn the water off to fix the problem, turn it off to be safe. Water exploding out of a pipe is not only stressful, but will also cause a huge mess that will only add time to your repair. When attempting a DIY plumbing repair, take your time and think through everything that you do.
Starting Without Making a Plan
Even the most experienced plumbers need a plan before beginning a repair. Do not start fixing a plumbing issue until you have done significant research about the process and have planned out how you are going to complete each step.
Confusing How Things Fit Together
If you attempt a repair too quickly and without a plan, you may forget how all of the parts fit together. In general, things are easier to take apart than put back together. Do not haphazardly take everything apart. Take note of how each component fits together. You can also take a picture of the plumbing at the beginning so you have a reference when trying to put everything back together.
Stripping or Splitting Parts
Many people believe that there is no such thing as fitting a pipe too tightly. However, being too aggressive with screws and other parts may strip or split the part, which will force you to take extra, time-consuming steps with your repair. Do not pull as hard as you can when tightening up things in your plumbing. Tighten it until there is resistance and then make slower, more intentional turns until you are confident that it is secure.
