What are the causes and effects of your pump sucking air?
A few of the more common reasons for a pump sucking air are the pump lid is cracked, or maybe the o-ring under the rim is broken or dirty. The inlet could be cracked; your autocleaner may have a hole in the hose or the water level may be too low.
A swirl in the skimmer box will indicate a low water level, which could also be the reason why your pump is sucking air.
The skimmer box weir door may also be jammed, rather than floating.
