Why is my Haskel Water Pump not cycling and has audible air leakage at the air exhaust port?

If your Haskel Water Pump isn't cycling and you hear air leaking, the issue might be due to a few reasons. It could be that the drive air volume is restricted, so try increasing the air line size. Another cause might be a damaged or undersized drive air o-ring P/N 56225, possibly due to age, in which case you should replace it. Also, check the spool o-rings P/N 546285 for wear or damage and replace them if needed.
