Manufacturer Defect causing leak

After a difficult install during s -20 cold snap, the heater was leaking internally. The heater was removed for inspection. A leak was found internal to the attached electrical box. A close inspection shows the stainless tube was not formed properly (too short) which meant the rubber compression seal could not seal on the tube properly. I was forced to use silicon to seal the tube properly. Hopefully the repair gets us through the winter.

Good replacement for Jacuzz J365 spa

Bought this to replace the heater in Jacuzzi J365 spa. SpaDepot is one of the few places that stocks all of the parts for my equipment at fair prices. Their site makes it easy to find the correct parts for people that do the repairs themselves

Fast service, with no additional surprise shipping/duty cost. Direct replacement heater for my Jacuzzi 2006 model J345, installed with no issues. Working as expected after replacing main circuit board due to blow relays.
