FAQs

What does WRAS-approved mean?

WRAS approval signifies that the product has been rigorously tested and meets the Water Supply (Water Fittings) Regulations 1999 in the UK, ensuring it is safe for use with drinking water and does not waste water.

Can this syphon fit any toilet cistern?

It is designed to fit most standard cisterns with a 1.5" bottom outlet. However, checking your cistern's internal height and outlet size is recommended for guaranteed compatibility.

How do I adjust the height of the syphon?

The syphon features a telescopic mechanism. Loosen the locking nut near the base, then extend or retract the upper section until the desired height is achieved, and retighten the nut.

How do I set up the dual flush mechanism?

The dual flush is typically activated by how long or hard you press the flush buttons or lever. Ensure the internal linkage between the buttons/lever and the syphon's internal rod is correctly connected and moves freely.

What is the lifespan of the silicone seal?

With normal use and standard water quality, the durable silicone seal is designed for longevity, typically lasting many years. However, it can be replaced if it shows signs of wear or damage.

Do I need special tools to install this?

Basic tools like an adjustable wrench or pliers, and possibly a screwdriver, are usually sufficient for installation. Ensure you have a cloth to dry any residual water.

Troubleshooting

Syphon does not flush or flushes weakly

Check that the lever arm is correctly adjusted to lift the diaphragm sufficiently. Ensure the water level in the cistern is adequate. Verify the flush pipe is not obstructed.

Cistern leaks into the toilet bowl (phantom flush)

Inspect the silicone seal at the base of the syphon for damage, debris, or improper seating. Ensure the syphon is sitting flush against the outlet. The seal may need replacement if damaged.

Dual flush buttons/lever not working correctly

Ensure the dual flush mechanism inside the cistern is properly connected to the syphon's activation rod. Check for any obstructions preventing the mechanism from engaging.

Syphon is too tall or too short for the cistern

Re-adjust the telescopic height mechanism. Ensure the cistern's internal height falls within the syphon's adjustable range.

Pros and Cons

Setup, Compatibility & Care

Setup:

  1. Ensure the cistern is isolated from the water supply and the old syphon is removed.
  2. Adjust the syphon's height by loosening the locking nut and extending or retracting the telescopic mechanism to match the cistern height.
  3. Position the syphon in the cistern, ensuring the 1.5" base sits correctly on the flush outlet.
  4. Connect the flush pipe to the syphon outlet.
  5. Adjust the lever arm so that it operates smoothly with the cistern lid and actuates the flush mechanism correctly when pressed.
  6. Reconnect the water supply and test the flush, making further minor adjustments to the lever arm if necessary.

Compatibility:

  • Suitable for most standard toilet cisterns.
  • Requires a 1.5" (approx. 38mm) diameter flush outlet at the base.
  • Internal cistern height should be compatible with the adjusted syphon length (typically up to ~24.3cm when fully extended).

Care:

  • Periodically check the silicone seal for any signs of wear or debris that might cause leaks.
  • Clean the syphon components if any sediment buildup is suspected, though this is rarely necessary with normal water quality.
  • Avoid using abrasive cleaners. A damp cloth is sufficient for external cleaning.
