All,.. on two sewers.She cleans then every week and uses "iron out" I think the porcelain glaze is getting kind of rough 'the shine].Will 3 gallon toilets get the job done on this long of a run....clear to the main, in the street? Theres just her and i here, and the dog,and the dog would rather go outside thank you if you need more info let me know bob s
