Your plumbing system is to thank for comfortable showers, clean clothes, and flushing toilets. When it breaks down, your household suffers. Fixing issues with supply lines, waste lines, and vent systems can seem like a big task, but you can address them confidently with the right preparation. Learn the ins and outs of your plumbing system and how to handle leaks, low water pressure, and clogs in our guide below.
Understanding Your Home’s Plumbing System
Every home plumbing system consists of three main components: supply lines, waste lines, and vent systems. Each plays an important role in delivering clean water and removing waste.
Supply Lines
Supply lines deliver water from either municipal water lines or private wells to your house. If a utility supplies the water, you can find a water meter and main shutoff valve on the main supply line. Knowing the location of shutoff valves is very important in case of plumbing emergencies.
Waste Lines
Waste lines drain dirty water from your home. These pipes are larger than supply lines, and can be made of plastic, copper, or cast iron. In rural areas, wastewater travels through pipes to a septic tank that feeds a septic field. Urban areas usually connect to a municipal sewer system. Regular maintenance, such as septic tank pumping, keeps the system functioning properly.
Vent Systems
Plumbing vents facilitate proper drainage, and prevent vacuum action from impeding wastewater movement. Every plumbing fixture must have vents, though some fixtures can share vent lines. Conventional vents are made of pipes that run through the house and extend through the roof. You might find admittance valves in houses in which traditional venting is not possible.
Types of Plumbing Pipes
Different plumbing pipe materials offer different pros and cons. Read more about how certain types of plastic pipes and metal pipes compare below.
Plastic Pipes
Plastic pipes have become increasingly popular in residential plumbing because they’re durable, easy to install, and resistant to corrosion. The three main types are below:
- Chlorinated polyvinyl chloride: These are more expensive than PVC pipes, and are common in hot water supply lines because they have a high tolerance for high temperatures.
- Cross-linked polyethylene: These are flexible tubes that are common for use in both hot and cold water piping. They are easy to install and bend.
- Polyvinyl chloride: PVC pipes are common in drainage systems and cold water supply lines.
Metal Pipes
Metal pipes, particularly copper pipes, are common for use in supply lines, and have a long history in plumbing applications. Copper is durable, but is more expensive than plastic, and may interact with minerals in hard water.
Pros and Cons of Different Materials
Each plumbing material has advantages and drawbacks. Plastic pipes are cost-effective, resistant to corrosion, and provide some insulation. They may not be suitable for all applications, though. For example, they may not be a good ideas for areas prone to freezing temperatures, as they can become brittle and crack.
Metal pipes, such as copper, are durable and feature antimicrobial properties. However, they can be more expensive than plastic and are prone to scale buildup in hard water areas. Consider factors such as local building codes, water quality, and budget when choosing plumbing materials for your home.
Essential Plumbing Fixtures and Fittings
Plumbing fixtures and fittings are the visible components of your plumbing system with which you interact daily, such as sinks, toilets, and showers. Understanding these elements can help you make informed decisions about maintenance and upgrades.
Sinks and Faucets
Modern faucets are available in various styles and finishes, and might include features such as touchless operation. Consider factors such as durability, size, and compatibility with your existing plumbing when choosing a sink. Thinking of these factor in advance can help prevent plumbing problems in your kitchen or bathroom.
Toilets
Toilets have become especially energy efficient in recent years, and low-flow toilets can save thousands of gallons of water annually. Consider factors such as flush power, water usage, and comfort features when selecting a toilet.
Showers and Bathtubs
Modern shower and bathtub features include water-saving showerheads, digital temperature controls, and rain shower systems. Make sure you have proper waterproofing and drainage setups in place when you install or replace these fixtures.
Water Heating Options
Water heating accounts for 14%–18% of a home’s total energy expenses, according to the United States Department of Energy. Consider installation cost, energy efficiency, maintenance requirements, and your household’s hot water demands when selecting a hot water heater.
Tank Water Heaters
Tank water heaters are the most common water heater types, and store hot water in a tank that can hold up to 120 gallons. These heaters use natural gas, propane, electricity, or fuel oil to operate. Tank water heaters can suffer from standby heat loss as the water in the tank cools between uses.
Tankless Water Heaters
Tankless water heaters heat water on demand, eliminating standby heat loss. These heaters warm cold water in a heat exchanger until the water reaches the desired temperature. Tankless water heaters can be more expensive than other types upfront, but they offer savings over time.
Alternative Heating Methods
You should also consider the alternative water heating methods below.
- Indirect water heaters: These use your home’s heating system to heat water, providing efficient operation during colder months.
- Heat pump water heaters: These extract heat from the surrounding air to heat water, offering high efficiency in warm climates.
- Solar water heaters: These systems use solar energy to heat water, potentially cutting water heating expenses by up to 80%.
Common Plumbing Problems and Solutions
Recognizing common problems with plumbing systems can save you time and money. Read more about how to address and repair common plumbing problems below.
Leaks
Leaks can occur in pipe joints, fixture connections, or other parts of your system. Common causes include loose fittings, cracked pipes, and faulty valves. Tightening connections or applying plumber’s tape may help to repair minor leaks, while more severe leaks may require professional assistance. Regular inspections and prompt repairs can help homeowners prevent issues that may lead to water damage and waste.
Clogs
Address clogs in drain lines immediately to prevent overflows. You can address most toilet clogs with a plunger, and cleaning the P-trap beneath the sink can usually clear sink clogs. If you can’t locate or dislodge a clog, call a professional plumber.
Low Water Pressure
Mineral buildup in pipes, leaks, or problems with the municipal water supply can all lead to low water pressure. To diagnose low water pressure issues, check to see if the issue affects all of your fixtures or just one. Clean aerators and showerheads regularly to prevent mineral buildup. If problems persist, consult a plumber.
Plumbing Maintenance Tips
Regular maintenance is key to keeping your plumbing system in top condition.
Regular Inspections
Visually inspect exposed pipes, fixtures, and appliances regularly. Look for signs of leaks, corrosion, or unusual house noises. Check the water pressure, and drain flow in all fixtures. Consider annual professional inspections too.
Preventive Measures
Take the preventive measure below to keep your plumbing system in good shape:
- Avoid flushing nonbiodegradable items down toilets.
- Insulate pipes in unheated areas to prevent freezing.
