Moe the Sloan “flushmate” is used by several manufacturers for power assisted toilets.
The problem with this product is the noise level and you will also need to make your own repair tool for it.
I was fortunate enough to attend the Sloan class for their products given for the greater NYC toilet change out.
My personal choice would be a gravity system unless it is for a commerical use.
The residencial(toilets) models seem not to work as well for some reason IMHO . If you still want a pressure assisted type GET ONLY a Sloan. Have a great one
