What I should use to seal the joints of cast iron pipe ? These are the drains for the toilet and the sink . They may get a drip or two at each joint .
Thank you

Simple repair. Go down to the local Rent-All place and ask for inside and outside caulking irons, (see image) just recaulk the lead joints and you'll be fine. Good luck, Tom
