Made by Waterway

1/8 HP Circulation Pump

This hot tub and spa circulation pump is very much as it sounds, powerful and reliable.

The 'Iron Might' hot tub circulation pump is versitile and a common replacement for the Aqua-flo Circ Master pump, it can be found on spas such as Hyrdospa, Costco, Southwest Spas and many other hot tub brands.

You will know in an instant if this is the right hot tub circulation pump replacement for you due to its distinctive yellow wet end attachment.

Connecting the pump to the plumbing please see the following guide: Hot Tub  Union Guide

Please note WaterWay are slowly changing this pump to a new motor, which is seen in Image 2, the yellow pumps are becoming rarer and the wet end on is now only available in Black.

If you need a new cable please see hot tub pump cables

Replacement Mighty Iron Circulation Pump
Friday, 25 April 2014  | 

Thanks for the replacement pump that has now been superseded by a more efficient Italian motor. Be aware that the pump mounting height is different and will need to be shimmed as the baseplate is of a lower profile. Thanks for the advice,
