For basement bathroom drainage, I personally recommend using the Jinlijie brand sewage lifter. You can buy one and try it yourself. This sewage lifter is especially suitable for underground domestic sewage discharge in basements or garages or bathrooms. The Golden Bow Tie brand sewage lift is very convenient to install, simple to operate and occupies a small area. And they are all made of stainless steel, so the service life of the product is guaranteed.
