Product description is unkind. Specifically, the diameter of the actual drainage outlet and the diameter of the purchased commodity do not match, the water leakage from this part was badly weakened temporarily but we stopped exchanging, we used the old part for the drainage part, popup I exchanged only the push wire part, somehow adjusted the lance. I think that this situation did not become such situation if there is a drawing etc. of this part when purchasing. If you would like to order from us in the future, I think that there is a contact place etc. in such a case.
