Common Spare Parts
OLI's popular spare parts include flush mechanisms, fill valves, and dual-flush buttons. If unsure, utilize our Identification Service above.
Common Faults and Fixes
Water continuously running
Often due to a faulty flush valve seal or maladjusted float. Exact part match is best confirmed via photos.
Weak flush
Commonly caused by an incorrect flush valve setting or a worn out diaphragm. Inspection and photo submission can assist in diagnosis.
Leak at connection joint
Might be due to misaligned fittings or worn seals. Photos and precise measurements are crucial for accurate replacement.
Overfill or underfill
Usually a fill valve issue; checking the float height and valve condition is advised.
Button sticking
Often caused by dirt or limescale build-up under flush buttons. Cleaning and adjustment may resolve this.
Seal degradation
Old seals can cause leaks around components. Matching seal specifications is essential for optimal fitting.
