This collection focuses exclusively on uPVC plumbing supplies designed for a wide range of domestic installations. We've curated a selection of fittings, pipes and connectors crafted from this durable thermoplastic material, ideal for both new builds and renovations requiring a cost-effective and robust solution. uPVC is known for its resistance to corrosion, making it suitable for various water pressures and temperatures commonly found in UK homes.
These supplies are designed for use within cold water plumbing systems. It's crucial to note that uPVC is not typically compatible with hot water systems without appropriate thermal insulation. Selecting the correct uPVC components based on your project’s specifications – considering pipe diameter, pressure rating and intended application – is paramount to ensure a safe and lasting installation.
Available items include various lengths of 110mm and 150mm uPVC pipes, solvent welding joints, threaded fittings, bends, elbows and stopcocks. Always consult relevant building regulations and plumbing codes before commencing any work. Please review the manufacturer’s specifications for each product to ensure compatibility with your chosen system.
FAQ
What is uPVC suitable for?
uPVC is primarily suited for cold water plumbing installations, offering resistance to corrosion and a cost-effective solution. It's generally not recommended for hot water systems without adequate thermal insulation due to heat-induced expansion and potential damage.
How do I join uPVC pipes together?
uPVC pipes are typically joined using solvent welding – applying a special adhesive that creates a strong, permanent bond. Ensure the pipe ends are clean and free of contaminants before applying the weld solution.
What tools do I need to work with uPVC?
You’ll typically need a solvent welding kit including a heating tool (usually a hot plate), a cutter for trimming excess pipe, and a deburring tool for smoothing edges. Safety glasses are also essential.
Is uPVC suitable for external plumbing?
While uPVC can be used externally, it's crucial to select UV-resistant grades specifically designed for outdoor applications. Standard uPVC will degrade over time with prolonged sunlight exposure.
What are the different sizes of uPVC pipes available?
We offer a range of diameters, most commonly 110mm and 150mm for standard domestic plumbing. Larger diameters may be required for specific applications like rainwater drainage or specialist installations; always check your project needs.
How do I prevent leaks in uPVC joints?
Ensure all connections are made correctly, using the appropriate fittings and applying sufficient solvent weld. Regularly inspect joints for any signs of movement or damage and re-weld if necessary.
What is the lifespan of uPVC plumbing?
With proper installation and maintenance, uPVC pipes can typically last 50-75 years in a standard domestic setting. However, factors like water pressure and external conditions can affect longevity.
Can I use different types of sealant with uPVC?
While some sealants may be compatible, it’s generally recommended to use solvent welding specifically designed for uPVC. Using incompatible sealants could compromise the strength and integrity of the joint.
What is the minimum internal diameter for a 150mm uPVC pipe?
The minimum internal diameter for a 150mm uPVC pipe is typically around 125mm, allowing adequate flow for standard household water usage. Confirm this with the specific product specifications.
Should I use threadless or threaded fittings with uPVC?
Solvent welding joints are most commonly used with push-fit (threadless) fittings as they provide a watertight seal without requiring threading. Threaded connections can be used for specific applications but require additional sealing tape.
