OEM Watkins No Fault 4000 PDR Heater replaces all previous no fault 4000 versions on Hot Springs and Tiger River spas from 2003-2009. Can also be used to replace the 73790 6KW No Fault version, because it will draw less amperage and extend the life on your heater relay board an breaker.
The heater is designed with a double pass to heat water efficiently.
Your old sensors simply unscrew from the old heater and thread into the new one.

Some of the original No Fault 4000 heaters had a built in pressure switch and this heater can still be used, but you will need to jumper the pressure switch wires going to your IQ2020 board.
