While it’s a great idea to do plumbing work on your own, there’re several mistakes may arise, especially among inexperienced homeowners. It’ll help to know the plumbing mistakes you should avoid so as to keep your plumbing system and home safe. 

Mistake #1: Forgetting to Shut Off the Main Water Supply

It’s important to shut off the main water supply when doing most plumbing projects. Forgetting to do so before working on a plumbing repair or installation may lead to water wastage and flooding.

For minor repairs, you can simply shut off the valve that stops water flow to that fixture or pipe. For major projects, or when you can find a valve to a specific repair area, then shut off the main water valve.

Mistake #2: Connecting Copper Pipes to Galvanized Pipes

Corrosion is inevitable when a copper pipe and a galvanized pipe touch each other. Most homeowners don’t know this fact. They rush to repair their old galvanized pipes with new copper pipes. To connect a copper pipe to a galvanized pipe the right way, you’ll need to use a special connector known as a dielectric joint/union. This joint comprises of a rubber washer and plastic sleeve that prevent the copper pipes and galvanized pipes from connecting to each other directly.

Mistake #3: Doing Unpermitted Work

You can devalue your home by doing major plumbing changes without seeking the necessary permits from your local authorities. A home that undergoes unpermitted plumbing work might take more time to find a buyer and even sell at a lower rate. Some states demand that contractors have to get permits to do major plumbing changes while others allow property owners to get permits themselves.

Whichever way, you should ensure that you get the required permits when doing major plumbing work such as re-piping or remodelling a bathroom or even bathroom floor. Permits allow local construction officials to oversight a home improvement project. By so doing, local authorities ensure that the project is done according to the set plumbing standards and codes. Although it might cost you some money to get a permit upfront, it’ll keep you protected from fines related to doing major plumbing work without a permit. The permit will also ensure that your project is done the right way.

Mistake #4: Using Chemicals to Clear a Blocked Drain

Most homeowners view liquid based drain cleaners as miracle products. You only need a little amount of a drain cleaner chemical to unclog your drain or sewer line. However, using chemicals to clean the drain comes with bad effects on galvanized pipes. Using chemicals on galvanized pipes can lead to leakage and corrosion.

There’re many effective ways of clearing clogs without using toxic chemicals. For example, if you have a clogged drain, you can solve this unpleasant situation quickly. You can use alternative drain cleaning products such as:

  • Natural products- You can clear a slowly flowing drain using baking soda, vinegar, and hot water. You’ll simply sprinkle some baking soda into the drain, then pour some vinegar into the drain and allow the solution to settle for some hours. Then flush the drain with some hot water.
  • Plumbing auger– An auger is operated manually. It cleans most clogs without using chemicals. You can use it yourself without hiring a plumber.

In case no unclogging option works for you, then contact your local plumber. A reputable plumber will clear the clog without using any harsh chemical that can result in damaging your plumbing system.

Mistake #5: Plumbing Without Proper Skills

Some homeowners attempt doing challenging plumbing tasks without insurance and licensing, something that most professional plumbers can offer.

The professionals know everything about plumbing. They undergo thorough training and learn how to use the best plumbing tools and equipment. Moreover, they under apprenticeship for some years before doing an exam to get a license. As such, professionals ensure you get high-quality results and keep your home safe.

Doing a major plumbing project without the necessary skills and tools can result in costly damages to your property. Doing plumbing work yourself without the required skills might cost you more money when you make damages. You might end up paying a plumber to redo the work.

Nevertheless, it can be challenging to determine when a plumbing task is not ideal for DIY. You can find out by consulting with some plumbers before starting the project.

Ask them questions about what it involves to complete the project and how it should be done. Talking to the experts will assist you in gauging the complexity level of the project and whether it’s possible to do it yourself.
