Applications, Pros and Cons, and Essential Installation Products
Thanks to their durability, low cost, and ease of installation, using PVC plumbing pipes has become increasingly popular. Whether you are a working professional in the field or a homeowner looking to upgrade your plumbing system, understanding the ins and outs of PVC pipes can help you make informed decisions.
In this blog post, we will delve into the world of PVC pipes and explore when and why they are used, the pros and cons, and essential products needed for PVC pipe installations, as well as what homeowners should know.
Applications Using PVC Plumbing Pipes
PVC plumbing pipes are a versatile and commonly used option for various plumbing applications in homes and buildings. From the ground up, PVC pipes are often used for drain, waste and vent (DWV) systems. These carry wastewater from buildings and homes, eventually connecting to the city's main or an on-site septic system. The larger pipes in the DWV system branch off into smaller pipes as they reach different areas of the structure.
Another application of PVC pipes is for water mains that bring cold water into buildings and homes. Since PVC is suitable for cold water, it is commonly used for this purpose. Furthermore, PVC pipes are employed for stormwater runoff systems, channeling excess rainwater away from the property and into designated city mains or drainage systems.
Even in specific scenarios like hot-water tanks, PVC pipes play a role. Power vents, used for venting exhaust gases and allowing air intake in hot-water systems, often utilize PVC pipes. These vents facilitate the safe expulsion of combustion byproducts without involving high heat levels.
The Pros and Cons of Using PVC Plumbing Pipes
PVC pipes offer advantages over older options like galvanized metal or cast iron.
-
Easier to Install: With older materials, such as cast iron or galvanized pipes, precise measurements and cutting were required beforehand. In contrast, PVC pipes can be easily measured and cut on-site, making the installation quicker and more convenient.
-
Resistance to Leaks: PVC pipes have solid and well-joined connections because they are chemically fused at the joints. In comparison, older lines often rely on threaded connections or rubber couplings, which have a higher potential for leaks. Although sealants and rubber bands are used to prevent leaks, factors like the pipe’s quality or the sealing method's effectiveness could still lead to potential leaks.
-
Resistance to Corrosion: Unlike cast iron or galvanized pipes that can corrode over time due to the wear-off of protective coatings, PVC pipes remain unaffected by moisture and other factors. This corrosion resistance helps prevent failures in the pipes, such as cracks or holes, which can lead to leaks or the escape of sewer gas.
-
Lightweight: PVC pipes’ light weight makes them easier to handle and transport on job sites, especially for large commercial projects or installations requiring larger pipe diameters. This easier handling also benefits wholesalers storing and moving PVC pipes, making them easier to stack and handle without heavy machinery.
-
Cost: PVC pipes are typically more affordable than their cast iron or galvanized counterparts because plastic materials are generally less expensive than metals. This cost-effectiveness makes PVC pipes a more affordable option for plumbing systems.
Essential Products for PVC Plumbing Pipe Installation
When working with PVC pipes, you will need several products for installation, securing, and assembling the joints. Here are some of the essential products:
- DWV Pipe Hangers: These hangers are specifically designed for PVC pipes and are used to secure the pipes during installation. They are ideal for ceiling or wall installations. Oatey® Universal DWV Pipe Hangers are made of durable polypropylene and ABS plastic and are used to support copper, PVC, ABS, galvanized, black iron and cast iron piping to joists and rafters. The strap orientation can be reversed based on installation needs and can be adjusted to accommodate 1–6 in. diameter pipe. These pipe hangers feature straight and angled mounting holes and preloaded ring shank nails for easy installation in tricky spaces.
- DWV J-Hooks: Made of durable ABS plastic, J-hooks include pre-loaded nails in the stem for easy installation. A diagonal nail path offers flexibility for tight spaces, and a locking finger provides a tight hold in inverted applications. Oatey® DWV J-Hooks have additional holes that secure cable ties and other fasteners.
- PVC Cement: PVC cement is crucial for assembling the joints of PVC pipes. It is used with a primer to fuse the pipe and fittings chemically. The primer preps the surfaces by softening them, making them tacky. Then, the cement is applied to create a strong bond. Oatey® and MASTERS® Cements offer products for various commercial and residential applications, including potable water, DWV, industrial, pool/spa, turf/irrigation, sewer, and many more.
These products are essential for working with PVC pipes, ensuring proper installation, secure connections, and the ability to test and verify the system's integrity.
PVC Plumbing Pipe Maintenance Tips
Not much effort is required to maintain drain or sanitary drainage systems. However, being mindful of what is being flushed down the toilet is essential. Items like feminine products or excessive amounts of paper can cause blockages or clogs over time. Educating household members about proper disposal practices is critical to avoid potential issues.
Similarly, in kitchen pipes, substances like grease can stick to the inside walls of PVC pipes, potentially leading to blockages or reduced water flow. Taking precautions to minimize the amount of grease and other residues going down the drain can help maintain clear and efficient plumbing.
Overall, PVC pipes are highly durable and long-lasting. With proper installation and care, PVC pipes can last many years without major issues, making them a reliable choice for your plumbing system.
