2018 Macerator hose

Hi - I have searched and found great info on older model macerator hoses. It looks like they are 0.75" ID and 1" OD. Does anyone happen to know if the 2018 model uses the same size hose (0.75 ID)?

It would really be simpler if they used the standard Clean Dump hose (given the Clean Dump is clearly the system since its labeled on the inside of the macerator control panel door)....but obviously they haven't been in the past.

Thanks for any help!

I don't have a newer Interstate but I don't believe they have changed the hose size because a 1" ID (1.25" OD) will not fit on the take-up wheel they use (or rather, the hose would not be very long).

The use of a .75" ID hose puts pressure on the pump and I've had to replace mine once because of a bolt on the housing failing likely because of this issue.

Verify your model number - this is on my 2012.
