Product Information
Full details
The Wavin Osma Overflow Solvent Weld Tee (21.5mm, White) is designed for plumbers and DIY enthusiasts needing to create a secure, 90-degree connection for overflow pipes. Its key benefit is providing a permanent and leak-free joint for efficient water drainage from boilers, cisterns, or tanks. A caveat to consider is the need for solvent cement for installation, which requires proper ventilation and handling.

FAQs
What type of solvent cement should I use?
Use a solvent cement specifically formulated for ABS and PVC-U plastics, such as Wavin Osma Solvent Weld Cement. Always follow the cement manufacturer's instructions.
Can I use this tee for hot water pipes?
No, this fitting is designed for cold water overflow and condensate drainage. It is not rated for hot water applications.
What is the maximum temperature and pressure rating?
This fitting is intended for low-pressure overflow and condensate applications and is not pressure-rated. It is suitable for temperatures typically associated with boiler condensate and cold water systems.
How do I ensure a permanent and leak-proof joint?
Proper preparation of pipe and fitting surfaces, correct application of solvent cement, immediate and firm joining with a slight twist, and adequate curing time are essential for a permanent and leak-proof joint.
Can this fitting be painted?
While painting is possible, ensure the paint is compatible with ABS and PVC-U. Unpainted surfaces offer the best assurance of material integrity. Test paint compatibility in an inconspicuous area first.
What does 'Solvent Weld' mean?
Solvent welding is a process that uses a solvent-based cement to chemically fuse two pieces of plastic together, creating a single, solid, and permanent joint.
Troubleshooting
Joint is leaking after installation.
Ensure proper application of solvent cement and sufficient curing time. Re-cut and re-join the pipe if the initial fit was poor or if the joint was disturbed before curing.
Difficulty inserting pipe into the fitting.
Check for obstructions or damage inside the fitting socket. Ensure the pipe end is cut square and deburred. Ensure the correct type and amount of solvent cement is used, as it acts as a lubricant.
Fitting appears brittle or discolored.
This may be due to excessive exposure to UV light or incompatible chemicals. Ensure the installation area is suitable and protect the fitting if necessary.

Setup, Compatibility & Care
Setup:
- Preparation: Ensure both the pipe ends and the inside of the fitting sockets are clean, dry, and free from dust or grease. Cut the pipe ends square.
- Dry Fit: Temporarily assemble the joint to check the fit and ensure the pipe is inserted to the correct depth mark (if applicable).
- Apply Solvent Cement: Apply a generous, even coat of appropriate solvent cement (e.g., Wavin Osma Solvent Weld Cement) to both the pipe end and the inside of the fitting socket.
- Join: Immediately push the pipe into the fitting socket with a slight twisting motion until it reaches the full depth. Hold firmly for 30 seconds to prevent the pipe from backing out.
- Curing: Allow the joint to cure for the manufacturer's recommended time before stressing or testing the system. Ensure good ventilation during application and curing.
Compatibility:
- Compatible with Wavin Osma condensate fittings.
- Designed for use with PVC-U pipe of the corresponding 21.5mm diameter.
- Use only approved solvent cement specifically designed for ABS and PVC-U.
Care:
- The fitting itself requires no regular maintenance once installed.
- Periodically check connected pipework and appliances for any signs of leaks or blockages.
- Avoid exposing the installed fittings to excessive external heat or chemical contaminants that could degrade the ABS or PVC-U materials.
