Reliable Wastewater Performance
The 40mm ABS Solvent Weld Waste Pipe delivers strength, compliance, and long-term reliability—making it the dependable choice for modern bathroom and kitchen drainage systems.
1. What is a 40mm waste pipe used for?
A 40mm waste pipe is commonly used for baths, showers, kitchen sinks, and dishwashers, where a higher water flow is required compared to basin waste.
2. What is the difference between 32mm, 40mm, and 50mm waste pipes?
32mm – Washbasins and bidets
40mm – Baths, showers, kitchen sinks, dishwashers
50mm – Commercial use or where multiple waste pipes combine into one flow
Choosing the correct size helps prevent slow drainage and blockages.
3. What material is this waste pipe made from?
This pipe is manufactured from ABS (Acrylonitrile Butadiene Styrene), a strong, impact-resistant plastic that offers durability, a smooth internal bore, and long service life.
4. Is this waste pipe manufactured to UK standards?
Yes. It is manufactured in the UK to BS EN 1455 and is Kitemarked, ensuring high quality, reliability, and compliance with recognised standards.
5. How do I correctly make a solvent weld joint?
To create a secure solvent weld joint:
Clean and dry both the pipe exterior and fitting interior
Apply solvent cement (e.g. SC250) to both surfaces
Push the pipe fully into the fitting and twist slightly
Wipe away excess solvent
Leave for 5 minutes to set and 12 hours before testing
6. Are solvent weld joints removable once installed?
No. Solvent weld joints are permanent and cannot be dismantled once set, so accurate measurement and alignment are essential before bonding.
7. Can this 40mm waste pipe be cut to size?
Yes. The pipe can be cut down to the required length. Ensure the cut end is square, clean, and free from burrs before solvent welding.
8. Do waste pipes require ventilation like soil pipes?
No. Waste pipes only carry wastewater and do not require a venting system, unlike soil pipes which carry foul water and gases.
9. Can this pipe be used with push-fit fittings?
No. This pipe is designed for solvent weld systems only. Push-fit fittings use different tolerances and sealing methods and should not be mixed with solvent weld pipework.
10. What safety precautions should be taken when using solvent cement?
Always work in a well-ventilated area, keep solvent cement away from heat or naked flames, and avoid skin contact. If contact occurs, wash thoroughly with soap and water.
The 40mm ABS Solvent Weld Waste Pipe is a dependable, standards-approved solution for higher-flow domestic waste applications, delivering strong, permanent joints and smooth, efficient drainage when installed correctly.
