FAQs

What size flush outlets does this valve fit?

The Fluidmaster PRO550UK fits both 1 1/2″ and 2″ flush outlets.

Can I adjust the amount of water used for flushing?

Yes, the water-saving adjustable flush volumes for both full and reduced flushes can be customized.

Where can I install the flush button?

The dual flush button is designed to fit top, front, or side applications on your toilet cistern.

What is the maximum height of the overflow pipe?

The overflow height is adjustable from 8 1/2″ up to a maximum of 13 1/2″.

What is the length of the cable for the flush button?

The cable length provided is 350mm.

Is this valve suitable for all types of toilets?

It is designed for standard toilets with 1 1/2″ or 2″ flush outlets. Always measure your outlet to be sure.

How do I clean the flush valve?

Gently wipe the external components with a damp cloth. For internal cleaning, follow the manufacturer's instructions, which usually involve removing the valve and rinsing it.

Troubleshooting

Cistern not filling completely

Check the water supply valve is fully open. Ensure the overflow height is set correctly and not too low, preventing the cistern from reaching its optimal water level.

Flush is weak or inconsistent

Verify that the flush volumes are adjusted correctly. Ensure the cable connecting the button to the valve is not snagged or too tight. Check for any debris obstructing the valve seat.

Cistern continues to leak after flushing

Ensure the valve is properly seated on the flush outlet and the tightening nut is secure. Inspect the rubber seal for damage or debris and clean if necessary.

Dual flush button is stiff or difficult to press

Check that the cable is properly aligned and not kinked. Ensure no obstructions are around the button mechanism.

Pros and Cons

Pros

  • Promotes significant water savings through adjustable dual flush volumes.
  • Flexible installation options with adaptable button and overflow heights.
  • Fits a wide range of standard toilet cistern outlets (1 1/2" and 2").
  • Modernizes toilet functionality with a dual flush mechanism.
  • Reliable performance expected from a reputable brand like Fluidmaster.

Cons

  • May require some DIY aptitude for installation.
  • Cable length might be limiting in exceptionally large cisterns.
  • Specific compatibility check needed for very old or non-standard toilet models.
  • The white color may not match all toilet aesthetics.

Setup, Compatibility & Care

Compatibility: This valve is designed to fit standard 1 1/2″ and 2″ flush outlets. Before purchasing, measure your toilet's flush outlet to confirm compatibility. The dual flush button is suitable for top, front, or side mounting applications.

Setup: Installation typically involves shutting off the water supply to the cistern, emptying it, and then removing the old flush valve. The PRO550UK can then be fitted by securing the valve base to the flush outlet and connecting the dual flush button mechanism via its 350mm cable. Adjust the overflow height as needed and reconnect the water supply. Detailed instructions are usually included with the product.

Care: To maintain optimal performance, regularly check the valve for debris. Cleaning the cistern periodically will prevent sediment buildup that could affect the flush mechanism. Wipe the flush button with a damp cloth if it becomes soiled. Avoid using abrasive cleaning chemicals directly on the valve components.
