Common Spare Parts

The most frequently requested Alca Plast spares include flush mechanisms, seals, connectors, and buttons. If you are unsure which version you need, use the Identification Service above.

Flush valves: Essential for ensuring proper water flow and stopping leaks.
Seals and gaskets: Commonly needed for maintaining watertight joints.
Connectors: Necessary for linking cisterns to bowls, and for smooth operation.
Flush buttons: A frequently replaced part for upgraded aesthetics and functionality.

Common Faults and Fixes

Leakage at base
Often caused by worn seals or incorrectly fitted connectors. Verify the connection and replace seals if needed.
Button not responsive
Typically linked to an issue with the flush mechanism or button connection. Check for obstructions and proper alignment.
Weak flush
A common problem that can be caused by misadjusted flush valves or clogging.
Cistern filling too slowly
Usually due to blocked inlet valves or faulty washers, which can be checked and replaced as needed.
Water runs continuously
This might be due to a stuck or malfunctioning flush valve, requiring adjustment or replacement.
Debris in cistern
Sediment and debris can build up and affect the operation of flush and fill valves. Regular cleaning is recommended.

Technical Support FAQ

How do I identify my Alca Plast cistern model?+
Check the inside of the cistern and the flush button area for model codes. If not clear, email photos to our support team for help.
My Alca Plast button is not responsive, what should I do?+
Ensure the button connection is secure and not obstructed. If issues persist, consider replacing the mechanism for smoother operation.
What photos should I send for the Identification Service?+
Send a full item photo, close ups of markings, photos of the removed part, and a measurement reference such as a ruler for scale.
How do I identify a flush valve type?+
Look for moulded markings on the valve body and note the button layout. A clear photo of the valve in the cistern often confirms the style quickly.
What if my part has no code or markings?+
That is common on older parts. Photos and measurements often allow identification by shape and dimensions.
Does Alca Plast share parts with other brands?+
Some parts may have similarities, but it is vital to identify them by photos and model codes for exact matches.
Can you help if I only have the front of the toilet or cistern?+
Yes, but identification is faster if you can include a photo of the internal parts or connections along with any measurements you can take.
