The slab units have a macerator pump with an alarm in the utility room of the unit.
If the alarm goes off that means that the macerator pump is not working and do not run any water or flush
toilets.
There is a circuit breaker for the pump in the same box outside that the sprinkler system circuit breaker is
located.
WARNING: When the sprinkler system is drained for the winter it is easy to mistakenly turn off the macerator
pump also.
