Learn About Your Home's Plumbing

Home plumbing systems connect the home's plumbing fixtures such as sinks, showers, washing machines, and pools to the main water line. Professional plumbers undergo years of rigorous training in the classroom and on the field as apprentices to learn how to service plumbing systems. Homeowners should also have basic knowledge of their home's plumbing to properly maintain their system.

Knowing how the plumbing system works, what kind of maintenance it needs, and the warning signs that something is wrong can help homeowners to save money in the long run. A small plumbing issue can usually be quickly resolved, but leaving it in a state of disrepair can lead to expensive property damage and complicated repairs if it worsens. Learning about plumbing systems has a lot of benefits for homeowners.

The Main Water Supply

The complicated network of pipes and plumbing fixtures in a home connects to one main water source. Most people rely on city water, but rural homeowners often have well water.

A water meter measures how much water enters the home's plumbing. This meter is used to troubleshoot plumbing issues and for utility companies to bill for the amount of water being used. A damaged, leaking, or malfunctioning water meter can lead to higher utility bills, water damage, and low water pressure.

The water meter also has the main shut-off valve that cuts off the water supply for the whole home. Plumbers use the main shut-off valve to stop the water flow and safely service the plumbing system.

Water exits the home through drains in the plumbing fixtures. Once the water enters the drain, it travels to the city sewer or a septic tank. The pipes that carry wastewater away to be disposed of are called the sewer line.

Common Plumbing Fixtures


  • Showers
  • Bathtubs
  • Sinks
  • Faucets
  • Toilets
  • Dishwashers
  • Clothes washers

These are the main plumbing fixtures that are found in most homes. Some homes also have outside plumbing fixtures such as pools, hot tubs, fountains, and sprinkler systems. Properly maintaining plumbing fixtures by keeping them clean and replacing outdated parts helps improve the plumbing system's longevity and performance.

New plumbing fixtures are more eco-friendly and water-saving than ever before. Homeowners can save money on utility bills by replacing old plumbing fixtures with new, energy-efficient models. Saving water is good for homeowners' wallets and for the environment.

Plumbing Maintenance

Homeowners can lengthen the lifespan of their plumbing fixtures, save money on utilities, and prevent plumbing disasters by doing bi-annual maintenance. Drain cleaning services are one example of a beneficial maintenance service that homeowners can invest in to improve their plumbing performance.

Water heaters provide essential hot water for cleaning, bathing, and other daily tasks. When the water heater works, natural minerals such as calcium and magnesium in water separate into solid sediments. Over time these sediments build up and can cause corrosion. During maintenance appointments, plumbers drain water heaters safely and flush water heater tanks out to remove sediment buildup.

Plumbing maintenance should always be done by a qualified professional. During maintenance appointments, the plumber will have a chance to inspect the plumbing for signs of damage or malfunction that the homeowner may not know to look for. Benefits of hiring a professional plumber for routine maintenance include:

  • Improved safety
  • Less time spent on maintenance
  • Getting professional advice on how to improve plumbing performance
