The lead bend is deteriorating and badly holed, especially the part between wall and horizontal toilet spigot where it has been cemented in over seventy years ago when house built. Not sure how bad remainder of lead is. Soil stack is iron. A handyman suggested pulling it out after cutting both ends but unlike using modern core drills to make holes for 110 mm soil waste pipes the lead pipe I think is cemented in. Is it possible to core drill it out using a drill core bit a few mm wider than the lead pipe. The thickness of the wall is two clay bricks separated by a small gap, smaller than a cavity. I tried a number of times to seal holes in pipe indoors with plumbers mail and tape over but still leaks and over time holes got a lot bigger. So replacing pipe from toilet to iron stack with 110 mm PVC pipe. Be difficult to get lead pipe end out of toilet spigot and the soil waste stack. How to remove the hard cement? Hammer and chisel carefully without breaking the pan. For ease of access, how to remove the four badly rusted two and a half inch half inch slot flat head stuck screws securing pan to floor? Cannot get a flat blade in to saw screws between pan base and floor. I want to keep the high cistern and toilet bowl if possible.
