The swimming pools at Dewsbury Sports Centre will be closed until next weekend.
Kirklees Active Leisure, which runs the facility, had originally planned to close the pools from this Sunday, but a technical fault meant maintenance work had to be done earlier than planned.
A KAL spokeswoman said: “Due to essential planned maintenance work required at Dewsbury Sports Centre, KAL had scheduled a planned closure of the swimming pools from Sunday November 8.
“Unfortunately, due to technical issues, the pool has had to be closed earlier than scheduled. However, we will now be able to re-open slightly earlier than planned, on Saturday November 14.
“KAL would like to thank all of our customers for their patience during this period of disruption.”
