What is Installation in Plumbing?


Plumbing installation is a critical aspect of any construction or renovation project. For most people, plumbing installation refers to the plumbing fixtures like sinks, faucets and showers. Installation in plumbing actually refers to a vast and complex network of pipes, valves, and drainage systems. A well-designed plumbing system includes a clean water supply into your home, drainage pipes to remove waste, a number of appliances, and even the gas lines that provide fuel to heat your home and power your oven. Professional plumbers are skilled in planning, installing and maintaining the safety and overall health of your home. If you are considering new plumbing, you should understand everything that occurs between your main water line and the sewer.

A plumbing system works primarily to provide safe water into your home and ensure that waste is disposed of safely and efficiently, preventing the buildup of harmful bacteria and other contaminants. This means that installing a plumbing system requires careful planning and attention to detail. Working with a professional plumber makes certain that the system fits the specific needs of the property and is tailored to fit your needs. Both for new construction and for remodeling projects, a plumber will map out the layout of the system, identify potential obstacles and select the right materials for your home and also for the climate around your home.

What is the First Step in a Plumbing Installation?

Whether you are building an entire system or just installing a new water heater, the first step for a plumber is to plan and prepare. Obviously there are local codes and regulations, but expert plumbers are always working to design a long-term solution to protect your entire house. A single plumbing fixture or improperly installed water line can result in poor performance and even damage to your property. A malfunctioning drainage system comprises the health of your home and family. It’s essential to take the time to carefully plan out the plumbing system and gather all of the necessary tools and materials.

There are a number of DIY projects that homeowners can perform. For instance, if you want to install new sinks or replace a shower head, you may feel comfortable after watching a few online videos. If you take the time to plan and verify you have all the right tools and materials, then you are less likely to create a problem. Nearly every plumber has a story about an emergency repair that started as a DIY project. Many homeowners bite off a bit more than they can chew and realize too late that even plumbing fixtures are best installed by a professional plumber.

The key really is planning and designing before you take any action. In new construction plumbing, the first phase is typically the rough phase before any foundation or above-ground work begins.

How Do You Install Plumbing Systems?

Installing a plumbing system depends on the complexity of the project. A new construction project includes an underground rough-in phase where sewer pipes, vent pipes, drain pipes and water supply lines are installed before a foundation and walls are constructed. The second phase is usually referred to as the above-ground rough phase. During this stage all water pipes, drains, gas lines and familiar copper fittings are installed into the walls and floors where appliances and fixtures will be installed. This phase is one of the most important and time-consuming processes for a plumber.

A plumbing system is designed to last for decades. When any error is made during the rough in phases, water lines can fail, leak and potentially create very expensive repairs. Before walls are treated and decorated, plumbers strive to design and install systems that are durable and secure for your family. Whether during a new construction project or a remodel, the care and expertise of a plumber help prevent leaks and other disasters from befalling your home.

After rough in, fixtures are installed. These include all of the sinks, faucets, toilets, tubs, showers and appliances. While most homeowners do not attempt DIY projects in either rough-in stage, you may consider installing water heaters, dishwashers, ovens, refrigerators, clothes washing machines, faucets and maybe even a complete bathroom remodel. These projects can be fun and also disastrous. Consult with a plumber before you start any project.

5 Common Errors of DIY Plumbing Projects

Avoid these common mistakes when taking on your own project instead of working with a certified plumber:

  1. Using the wrong tools: One of the most common mistakes homeowners make when attempting a plumbing project is using the wrong tools. In the spirit of saving money, you may not have access or budget for a specialized tool. This can lead to damage to pipes, fixtures, and other components.
  2. Over-tightening connections: Hours of home repair shows and online tutorials cannot replace lived experience and training. Over-tightening connections quickly leads to damaged pipes and even breaking the new fixture you are installing. If you don’t know how much force to apply when tightening connections, most DIY homeowners err on the side of making connections too tight.
  3. Failing to turn off the water supply: Always know where you shut off valves. Before beginning any plumbing project, it’s essential to turn off the water supply to the affected area. Our team routinely arrives at costly water damage repairs that could have been avoided if the main water supply was closed.
  4. Ignoring leaks: Arriving at the finishing phase can be time-consuming and stressful in a DIY project. Overlooking small leaks or forgiving a slow drip is a side effect of exhaustion. Even small leaks can be a sign of a larger problem, and should never be ignored. If left unchecked, leaks can lead to water damage, mold growth, and other issues, and may require costly repairs.
  5. Improper drainage: In a remodeling project, some homeowners alter the system without realizing the implications. A deeper sink can create issues with drainage. A new basement bathroom project can disrupt the pressure of your entire water supply system. Using the right tools is important but you also need to understand the building system behind your plumbing.

What is the Last Phase of a Plumbing Installation?

Once the fixtures are mounted, sealed and the water supply pipes are reopened, the final phase of a plumbing installation is the testing and troubleshooting. This phase is critical to ensuring that the plumbing system is functioning correctly and free of leaks or other issues. A professional plumber will test the entire system even if you only installed a new water heater or replaced your water softener. Plumbing is vital to delivering water into your home safely and a minor issue like a leak or damaged vent pipes can compromise your family. Testing the installation ensures the water system within your home is secure and better than ever.

What Plumbing Installation Can Be DIY?

A properly installed plumbing system is a critical component of any functional home or business. Many installations are affordable to hire an expert plumber so for some homeowners the risk of a DIY project is too high. If you choose the wrong color for your bathroom, you can always paint over it. The risk of flood damage is a greater consideration.
