We are renovating our house, adding two additional bathrooms. There is an existing SVP at the end point of the drainage system. The two new bathrooms connect to the drain through a new connection at a different point [downstream].
Is there an alternative to a second SVP? This would have to be 2m above roof to meet regs regarding window clearances due to the gable end.
