this is a quick how to on replacing an old rusted fitting with a new PVC TEE using fernco fittings aka no hub coupling. no re-threading required and much simpler and faster if the space is not available. ask me anything if there are any questions about this or other renovation needs, I am not a professional but a handyman and jack of all trades, dabble in a bit of everything, from rc to automotive and housing.
Removing old galvanized pipes can be tricky, mainly because they usually have quite a bit of rust and corrosion where they meet tees, elbows,and couplers. In this video I discuss how to remove old pipe using a combination of penetrating spray ( I prefer PB), two pipe wrenches working in opposition, and a counter-intuitive first tightening that actually helps loosen the pipe. Thanks!
