When renovating or building a home, it’s important to understand the different types of plumbing materials available like PVC, copper, PEX etc. and choose the most suitable option for your needs. Factors like corrosion resistance, pressure rating, ease of installation and cost should be considered.
Selecting suitable plumbing pipe types is crucial for a well-functioning domestic plumbing system. The right pipes ensure efficiency, durability, and safety, addressing all your plumbing needs.
Several types of pipes are commonly used in homes:
Considerations such as water quality, soil properties, and sunlight exposure influence whether copper, PEX, or other common plumbing materials suit your needs. Cost, ease of installation, and usage also play a role.
This guide explores the most popular plumbing pipe options, as well as essential pipe fittings and fixtures. It covers the pros and cons of each to help you choose right for your homes’ needs.
The type of water supplied to your home is critical in choosing the suitable material for your plumbing pipes. Over time, hard water with high mineral content can corrode pipes. Understanding your water’s properties helps you determine the most compatible pipes for your system.
And contaminants require specialised treatment.
Copper, PEX, known for its flexibility and durability, and stainless steel, with their excellent corrosion resistance, are among the most commonly used materials, while PVC is versatile, accommodating most water types effectively. Ascertain if water treatment is necessary for other materials before making a decision.
The intended use for the water should also be taken into account.
Water heater lines need materials also suitable for high temperatures like copper. Supply lines experience frequent pressure fluctuations, which demand high-strength materials. And waste lines must resist corrosion from effluent, critical for your new plumbing fixtures.
PEX pipe, while suitable for bathroom plumbing systems, is less efficient for hot water applications. PVC and cast iron offer reliable options, more than PEX, for your bathroom renovation plumbing drains. Analyse the usage to pick right plumbing pipes your needs.
The type of water supplying your home greatly impacts the ideal plumbing materials to use. Soft water lacks these minerals but can still be corrosive in pipes.
Hard water contains high mineral content like calcium and magnesium, which can corrode copper and galvanised steel pipes over time, leading to leaks, low water pressure, and potential health issues.
For hard water, PEX and PVC pipes are favourable choices due to their resistance to corrosion and mineral buildup.
Going for clay-lined copper or stainless steel pipes upgrades durability.
But chlorinated soft water can still wear pipes over time.
PEX handles soft water well, while PVC works for supply but not drains/vents due to chemical interactions.
The intended use significantly affects the selection of the most appropriate plumbing pipe materials. Key considerations include:
Analyzing your plumbing requirements allows you to pick pipe options that offer a blend of strength, corrosion resistance, ease of use, and safety.
The soil type on your property is a crucial factor in choosing underground pipes. Soil composition and chemistry impacts buried pipes in several ways:
The most soil-resistant pipe materials for buried lines are PVC and polyethylene pipes, due their robust construction. Their impermeable plastic construction resists chemical corrosion and abrasion. High-density polyethylene (HDPE) also handles pressure surges well.
Concrete pipes offer excellent strength but are prone to cracking in adverse soil conditions. Although durable, steel and iron pipes are prone to quicker corrosion when buried. Selecting the appropriate materials guarantees that your soil type doesn’t compromise your pipes’ integrity.
Exposing plumbing materials to UV light can accelerate degradation and affect durability. Non-metallic pipes like PEX, PB, and PVC are especially vulnerable when used outdoors or in sunlight exposure.
The sun’s UV radiation can degrade the materials, making them brittle and more prone to cracks or leaks over time. Employing UV-resistant formulations or shielding can greatly enhance durability.
For PEX or PB pipes, compared other standard materials, look for UV-resistant grades like PEX-a or PB-R to use above ground or outdoors. Insulating lines can also help protect against temperature variations. For exterior PVC drainage systems, these kinds pipes using UV-stabilised and thick-walled Schedule 80 PVC piping is recommended over standard options.
Where feasible, run water lines in UV-protected conduits below ground. Use joint sealants/cements on outdoor plastic pushfit fittings too. Additionally, insulate copper lines that are susceptible to sunlight, particularly those carrying hot water.
Choosing the correct plumbing materials requires balancing initial costs with long-term value and durability. While higher-quality pipes, typically used in large-scale projects, are more expensive, they often justify their cost over time through durability.
Higher grade copper and stainless steel pipes have significantly longer lifespans of 50+ years when installed correctly. Though more expensive initially, savvy choices can save on replacement costs for cheaper pipes in the long run.
Likewise PEX-A, with its extreme temperature durability and corrosion resistance, offsets its price premium through decades of reliable performance without needing to repipe.
Consider your budget in conjunction with the maintenance requirements and longevity of materials such as PVC, PEX, copper, cast iron, and steel. Make your choice for the best fit for your needs, ensuring top-notch value even if they come with a higher initial expense. Quality plumbing materials save money and hassle long-term.
When selecting types of plumbing materials, homeowners have various options to consider including:
Additional factors like cost, application, water type and exposure conditions help determine the best materials for a home. Consulting with a pro helps you determine which type of piping and fittings are best suited for your specific plumbing needs.
Copper pipes have been a choice commonly used and favoured for decades thanks to their longevity and corrosion resistance in your house. Properly installed copper often lasts over 50 years, making it an important consideration for your pipe selection. The pipes are rigid, so require skill to install around bends, but handle hot and cold water efficiently.
Copper is widely used in plumbing and is unaffected by most water compositions, resisting corrosion and mineral buildup well.
This helps maintain water flow and quality.
Copper’s rigidity may complicate the installation process, especially when fitting your plumbing in tight spots.
On the downside, the initial cost of copper is higher than that of plastic pipes.
Overall, copper strikes an optimal balance of durability, corrosion protection, and reliable performance. The long lifespan offsets the higher initial investment, making it a sound choice for most homes despite some limitations.
PEX piping, usually used for its flexibility, has gained popularity in recent years as a durable plumbing solution. Made from high-density polyethylene, PEX is highly resistant to corrosion and mineral deposits. It handles both hot and cold potable water efficiently.
A key benefit of PEX is that it can easily be maneuvered due to its flexibility in pipe plumbing applications. The pipes can bend and fit tightly around corners, allowing easy installation in tight spaces. This flexibility also makes PEX more resistant to freeze damage compared to metal pipes.
PEX can use its resilience very well against common water types in your home plumbing. And PEX doesn’t transmit noise like copper pipes, ensuring quieter operation for your drains in multi-family housing. Overall PEX offers a cost-effective piping solution with good longevity when properly installed.
PVC (polyvinyl chloride) is a popular rigid plastic pipe used in both water supply and drainage applications. It offers an affordable, durable piping solution.
PVC pipes, resistant to corrosion and mineral deposits, have a lifespan of approximately 50 years. Its rigidity ensures there are no issues when it comes to handling pressure changes effectively. Smooth interior walls help maintain good water flow.
For drainage systems, PVC withstands exposure to effluents and soil chemistry, making them highly reliable. Joined correctly with solvent cement, make sure joints form secure seals. The extensive product range has adapted to come in various forms, providing cost-effective choices more than ever before.
Specialised tools and cement are also needed for assembly.
Overall, PVC piping provides excellent value and longevity for your cold water supply, irrigation, and drainage needs. With proper installation and protection, PVC reliably serves homes long-term.
Galvanised steel pipes were once a common type plumbing used for water supply lines. The pipes have an inner steel core coated with a zinc layer, protecting against corrosion. However, over time gaps in the coating can lead to rust and deposits internally.
Today, materials can such as galvanised steel is being phased out in many areas due to corrosion concerns reducing its lifespan to 15-20 years. The inner rust and mineral buildup gradually reduce water flow and pressure. And corrosion releases contaminants into the supply, posing potential health risks.
Though initially cost-effective, the short lifespan and corrosion issues of galvanised steel pipes make modern alternatives such as copper, PEX, and PVC more suitable for long-term plumbing. Though still seen in some older homes, new installations should utilise more durable piping solutions.
Cast iron pipes were historically used in drainage systems. Made by casting molten iron, they are rigid and durable if properly maintained. Yet, with time, cast iron is susceptible to rust and corrosion.
In their heyday, when comes to longevity, cast iron pipes offered unmatched performance over 50+ years. Coatings can help resist corrosion and abrasion from effluents, making this kind pipe ideal for certain conditions. Their rigidity offers superb pressure management, which means you can confidently upgrade older systems with cast iron in different configurations.
Over time, however, cast iron can become brittle and corroded, potentially requiring replacement pipes. Eventually cracks, leaks and blockages develop, requiring repairs or full pipe replacement. Modern plastic pipes avoid these drawbacks.
While cast iron still appears in older homes, understanding its pros and cons is vital as it is seldom installed today beyond matching existing drains in retrofits. PVC, ABS and polyethylene pipes instead offer superior corrosion resistance and long-term value.
When it comes to selecting plumbing materials, it’s vital to analyse your home’s specific needs. Factors like your water supply composition, intended applications, climate, and soil type all influence the ideal pipes to use.
In many home plumbing systems, durable options such as copper, PEX, and PVC provide a combination of efficiency and long-term reliability. With decades of experience, they can assess the specific needs of residential commercial properties and recommend the best plumbing materials for performance, safety and value.
Selecting the appropriate pipe material, such as copper, guarantees over 50 years of corrosion resistance, while PEX manages pressure changes effectively. PVC is affordable yet robust for drains. Where possible, consult a professional plumber from reputable local businesses like Blacktown Plumbing.
