Common DIY Plumbing Mistakes and How to Avoid Them
As someone who often opts for professional help to avoid plumbing mishaps, I highly recommend doing the same. A simple repair that could cost a hundred dollars can turn into a much more expensive issue if not done correctly. If you're considering tackling a plumbing job yourself, especially with limited mechanical aptitude, you may find it best to hire a professional plumber. However, it's important to be aware of the most common DIY plumbing mistakes, so you can avoid costly and extensive damage.
Understanding the Basics
The most common mistake when it comes to DIY plumbing is underestimating the complexity of the task. A phrase that frequently sums up potential problems is “What could possibly go wrong?” Understanding this can prevent a number of issues. Familiarize yourself with the basics of plumbing, such as the direction of water flow, the need for venting, and the proper use of shut-off valves.
Water Flow and Drainage
Water and sewage flow downhill due to gravity. Therefore, all pipes in your house are designed to slope downward significantly from their starting points to maintain this natural flow. Simply put, water and sewage cannot flow uphill. This means that when you encounter a backed-up toilet, the water is not being forced through a pump but rather flowing naturally. For this reason, venting is essential for proper drain function. Vent pipes that extend through the roof allow air to enter the pipes, ensuring smooth water flow when the toilet flushes.
Water Pressure and Safety
Hot and cold water pipes deliver water under significant pressure, typically ranging from 50 to 80 PSI (pounds per square inch). This high pressure is why it's crucial to turn off the main water supply before performing any work on fittings or valves. Without turning off the water, you risk squirting water across your living space as you cut through pipes. The main water supply is usually located at the entrance to your home and can be turned off by a single handle, cutting off both hot and cold water.
Cold Water and Hot Water Systems
Cold water enters your home and directly goes to the hot water heater, which then heats the water for use in the home. Turning off the main water supply will prevent water from flowing through the pipes, making it safe to work on any plumbing fixtures without worrying about a water leak. For instance, when working on a shut-off valve, ensure that you have turned off the main supply to the house. This simple step can save you from costly messes and ensure that your DIY project is successful.
Conclusion
By understanding the basics of plumbing and following the guidelines for water flow, pressure, and safety, you can avoid many common DIY plumbing mistakes. If you're unsure about any part of the process, it's always best to consult a professional plumber. Remember, what could possibly go wrong? Knowing the basics and taking the necessary precautions can save you a lot of time, money, and frustration. So, whether you're a DIY enthusiast or a beginner, approach your plumbing projects with the right information and tools to ensure success.
