This Pump is the replacement for the original HA440 Commonly Found On the Spaform Spas
1 set of unions included.
This pump is also the direct replacement for the discontinued GC150 with the blue wet end. It is not a straight swap for the GC150 as there are a few plumbing changes needed.
This pump will perform at its best with 2-inch plumbing. This pump does not always perform at its best when plumbed into 1.5-inch plumbing combined with running through a water diverter valve.
