My Airstream used a Thetford Sani-con 70494 so I wanted an exact replacement and stayed with a Thetford. However, I did change the model slightly to a number 70224 which has the gray water bypass. The bypass doesn't change normal operation, just gives you the option of allowing unlimited gray water when using full hookups without the tank filling and needing to periodically turn on the macerator. Kind of like the 3" hoses do.
I haven't put it to use yet, but the theory sounds good. Unlimited showers (well, so long as hot water holds out).

SO.... your macerator also failed at 7 years?? Coincidence?? Probably not.
Turns out that my tires, batteries and propane sensor all went out at the same time .... approximately 6 years...this is just another maintenance item??
The representative at Roadtrek just treated this like a normal wear and tear item......
The macerator gets a lot of use on my Sprinter since it doesn't have a gravity dump...the hose is permanently attached to the rig and just extends from the rig like an accordian.... you push the button and the pump evacuates the tanks..
I have to say the whole process of emptying our tanks at the dump station makes it a lot easier...we don't have to take out and attach any hose ...it's always there....
We just put the hose in the port, pull the black and gray tanks and press the button to activate the macerator.
Hopefully, it will be the solution ....The flow rate is 13 gallons per minute. Even though the hose is only 3 inches in diameter... the tanks usually evacuate faster than most other RVs we've observed.....no need to flush out the hose....it's automatically rinsed with the dumping of the gray water.....
