Somewhat surprised to read you coudnt buy an nrv for a Turbo unless you were trying local plumbers merchants. Saniflo spares are generally available for a considerable time after production of a model comes to an end and that doesnt happen often.Before you buy, check to see if you can get spares for the model your looking at.
Like a non return valve - they seem to be a common failure.
Else when installing ensure you have the piping so you can install an external valve, also a drain point in the outlet pipe so it can be drained off iff the macerator gets glogged up because er indoors etc. used wet wipes a lot.
Ditto the turboflush, I have one and cannot get a replacement valve so fitted an external one.
