Well, that is really a subjective question. Do you really need to go to the doctor for your annual checkups? Do you really need to get the oil in your car changed as suggested? There are no laws dictating that you do such things—but you probably do because you know that they really are in your best interest. The same is true of a sump pump. You are not going to have your home repossessed for negligence if you don’t have one in place.
But the potential problems that you may run into may leave you wishing that your home was no longer your problem! The sump pump serves one function and one function only, and that is to protect your home in the instance of flooding. This is not only important in areas where heavy rains or rapid snowmelt are common. Anything, including plumbing leaks, could necessitate the type of protection that only a sump pump in Tucson has to offer.
