TECE 8cm Slimline Replacement Outlet Valve | Genuine Spare Part

Is this the right TECE valve for your toilet? Before ordering, use these three “On-Site” checks to confirm you have the 8cm Slimline system:

1. The Lid Test: Lift your toilet seat and lid. If the lid does NOT touch the flush plate, you almost certainly have the 8cm Slimline cistern.

2. The Wall Profile: Is your toilet built into a standard-height wall rather than a short “half-wall” or under-window niche? The 8cm valve is designed for full-height slim cavities.

3. The Width: Pop the push plate off and look inside. The tank should be approximately 8cm narrow.

Genuine TECE Engineering The TECE 8cm outlet valve is the high-performance heart of your concealed cistern. While these units are built for longevity, internal wear or mineral buildup can eventually cause the mechanism to stick or fail.

When to replace this valve:

• Continuous Running: If water continues to trickle into the pan after the cistern has finished filling, the base seal or the valve housing is likely faulty.

• Flush Malfunctions: If the dual-flush buttons are no longer activating the flush correctly, or the valve is failing to reset after a cycle.

Technical Partner Parts:

• The Universal Inlet Valve: If your cistern is slow to fill or won’t stop filling, the inlet valve is universal across all TECE cisterns. You can find the TECE Universal Inlet Valve here.

• The 8cm Washer: If you have a very minor leak, you may only need the 8cm Outlet Valve Washer rather than the full valve.

• Q: My valve has a barcode on it; does it match this one?

  • A: While barcodes can vary by production batch, the primary factor is the 8cm cistern width. If your tank is narrow and the lid doesn’t hit the plate, this is the correct valve.

• Q: Can I use this in an under-window (low height) cistern?

  • A: Likely no. Low-height “undercounter” cisterns usually require the shorter 9.820.223 valve. This 8cm valve is designed for standard-height slim walls.

• Q: Does this include the base seal?

  • A: Yes, the valve comes complete and ready to drop into your existing TECE 8cm cistern.
