      recirc pump 74427 for Caldara spa retro

      Posted by Robert Ross on Dec 18th 2020

      This is the only pump available for all years of this spa It is MUCH smaller than original equiipment which is a problem as it is too tall for the space allocated for it in the spa especially after using the required hose adapters. This was overcome by manually cutting down the length of the adaper tube . The other issue is that despite the picture, there was no option to buy 110 or 220. This confused my repair guy the old one was 110 and he thought this one was 220. After a couple of phone calls, was able to convince him this was a dual voltage unit 110-220 which he could used in either situation. Once installed, it has worked fine. But it is 1/2 the size of the old one and looks like a small pond pump.
