Hello. This being our first house, we are unsure what to do in this situation. Our toilet is leaking at the base which we have figured may be a wax seal problem, but it is also underneath the linoleum. This is a basement toilet against the back wall of the house. We just sprayed down the back of the house and noticed this seeping in. We have noticed leakage on 3 occasions recently, all due to heavy rain, etc. Not sure where to begin here, please help!
