hi, the toilet bowl in our house was previously put in with not enough ''slope' from bowel to soil pipe.
consequently it drips very slowly all the time. some cement was put it to seal the bowel outlet pipe going into the soil pipe, but the cement seems to have never dried out, or the moisture has been absorbed into it and the cement is now going very crumbly.
is there a good way to make the seal? i.e. something that will dry out or set in damp circumstances.
thanking you john west
