When the Sanipro system is utilized in a bathroom, can any rear discharge toilet be used with it or does it have to be a Saniflo brand toilet? It looks like the toilet that comes with the system has a long extension about a foot long that seals into the grinding tank with the supplied rubber boot. Could't an extension be made from any rear discharge toilet to be used with the system. Would be much cheaper than purchasing the toilet they sell for it. I've asked Saniflo this question but have had no response.
