Actually, if the continually flowing blood of the fountain is an essential part of the mana of the pretender, peeing in it just might be considered to poison it. I can very easily imagine a fantasy scenario (and it has been used in several books) where some spirit is weakened by desecrating/poisoning it by means of any number of substances injected into waters or blood.

On the other hand, if the blood is not an essential part, but merely the by-product of the spirit inhabiting the fountain, then the fountain should probably be poison resistant.
