SFA seems to be the iconic brand of this type of device, and it must be agreed that it is absolutely perfect to fulfill its rôle.Il allows to install toilets, anywhere, in the basement or first floor, in places which were not originally designed for this type of use.The sanybroyeur fires automatically when you pull the toilet flush which it is raccordé.Il settled on a flat floor behind the toilet and with a little back from the wall, to avoid vibrations.Il is also perfectly silencieux.Chez me, I decided that the installation be done by a professional, although one finds on the net explanatory videos. There has indeed sewage and electrical standards to adhere to, and constraints on pipe diameter and pentes.Le sanybroyeur is discreet, small in size, and very silencieux.Reste the price, which represents some investment !
