Sfa in France is the first choice for hotel toilet sewage upgrading. I recommend an sfa sewage elevator, which is Shenglijie 1. The highest sewage temperature of this equipment can reach 90 degrees Celsius in five minutes, while the normal sewage temperature is 35 degrees Celsius. Its highest lift can reach 1 1m, and its protection level is IP 44. In terms of performance, it is very reliable.
