FAQs
What standards does this reducer comply with?
This Wavin Osma reducer is designed to connect to pipes and fittings conforming to BS EN 1451-1.
Can I use solvent cement with this fitting?
No, this is a push-fit fitting and does not require solvent cement. It relies on mechanical seals for watertightness.
What is the main advantage of push-fit waste systems?
The main advantage is the speed and ease of installation, saving time and labor costs compared to traditional solvent-welded or compression fittings.
How do I ensure a leak-free joint?
Ensure pipe ends are clean, squarely cut, and free from burrs. Push the pipes fully into the sockets until they reach the internal stop. Using silicone lubricant is also recommended.
What does 'spigot' and 'socket' mean in this context?
The 'spigot' end is the part that inserts into another fitting (the 40mm end). The 'socket' end is the part that accepts a pipe or fitting (the 32mm end).
Can I connect 32mm pipe to 40mm pipe directly?
No, you need a reducer fitting like this one to transition between the two different pipe sizes.
What is the material of the reducer?
The reducer is manufactured from black polypropylene.
Troubleshooting
Leak at the 40mm connection
Ensure the 40mm pipe spigot is clean, free from debris, and fully inserted into the socket. Check the integrity of the socket's rubber seal and the pipe's condition. Re-lubricate and reassemble if necessary.
Leak at the 32mm connection
Verify that the 32mm pipe is clean, cut squarely, and inserted fully into the reducer's socket until it meets the internal stop. Check the pipe for any damage that could affect the seal.
Difficulty pushing pipes together
Ensure pipe ends are clean and free from burrs. Use a silicone-based lubricant on the spigot and socket for smoother insertion. Do not force connections; if resistance is significant, check for obstructions or misalignment.
Reducer doesn't fit correctly
Confirm that you are using the correct reducer for your pipe sizes (40mm to 32mm) and that both the pipe and the fitting conform to the specified standards (BS EN 1451-1).
Pros and Cons
Pros
- Fast and simple installation due to push-fit technology.
- Reduces the need for specialized tools or adhesives.
- Durable polypropylene construction ensures a long service life.
- Complies with relevant British Standards for safety and performance.
- Versatile for connecting 40mm and 32mm waste pipes.
Cons
- Requires clean and correctly prepared pipe ends for a secure, leak-free joint.
- Limited to specific size transitions (40mm to 32mm); other sizes require different fittings.
- Black color may not match all visible plumbing aesthetics.
Setup, Compatibility & Care
Setup:
- Prepare Pipe Ends: Ensure the 40mm and 32mm pipe ends are clean, dry, and free from burrs or damage. A clean cut is essential for the seal.
- Lubrication (Optional but Recommended): Apply a small amount of silicone lubricant to the spigot end (40mm) and the socket end (32mm) for easier insertion and to protect the rubber seals.
- Connect 40mm Spigot: Insert the 40mm spigot end of the reducer into a compatible 40mm push-fit ring-seal socket until it is fully seated.
- Connect 32mm Pipe: Insert the 32mm waste pipe into the socket end of the reducer until it reaches the internal stop.
- Check Joint: Ensure both connections are secure and the pipes are aligned correctly.
Compatibility:
- The 40mm spigot is designed to connect to a 40mm push-fit ring-seal socket conforming to BS EN 1451-1.
- The 32mm socket is designed to accept 32mm waste pipe conforming to BS EN 1451-1.
- This reducer is part of the Wavin Osma Push-fit Waste system and is compatible with other fittings in the range (e.g., other adaptors and reducers).
Care:
- Regularly check all waste pipe connections for leaks. If leaks are detected, the joint may need to be dismantled, the pipe ends re-prepared, and reassembled.
- Avoid harsh cleaning chemicals that could degrade the rubber seals over time. A mild detergent and water are sufficient for cleaning the exterior.
