Common Faults and Fixes
Toilet running
Typically due to a worn flush valve or seal. Identify the valve by markings or measurements for the correct replacement.
Tap leaking
Often caused by a faulty mixer cartridge. Match the cartridge by shape and spline count to ensure a correct fit.
Weak flush
Caused by issues with the flush valve or an insufficient water level. Examine the mechanism for any wear.
Shower leaking
Leakage often results from worn seals or joints. Replace with compatible parts from photos and dimensions.
Toilet not filling
This issue can be associated with the inlet valve. Clean or replace as necessary.
Overflow issues
Overflow is typically a sign of a failing fill valve or faulty float. Inspect for integrity and size to get the right fit.
Technical Support FAQ
How do I identify my GSI toilet model?+
The model number is often located on the underside of the cistern lid or on the ceramic body. If unavailable, email us detailed photos.
My GSI tap is leaking, what do I need?+
Leakage is often due to a worn-out mixer cartridge. Identify the cartridge by its dimensions and style for selection.
What photos should I send for the Identification Service?+
Please send a comprehensive photo, close-ups of any markings, and detailed measurements, preferably alongside a ruler for scale.
How do I identify a flush valve type?+
Check for marking on the valve or the valve body itself. Photos from multiple angles can help us assist you better.
What if my part has no code or markings?+
This is common with older parts. Detailed photos and precise measurements help with identification.
Do GSI products share parts with other brands?+
Some generic parts may be compatible, but verifying through our Identification Service ensures proper fit and functionality.
Can you help if I only have the visible part?+
Yes, but identification is more effective when comprehensive photos and measurements are provided.
