In older times, it was acceptable for sump pumps to be routed into sanitary sewers. This practice was generally used for ease of installation but is now actually illegal! It’s amazing that plumbing laws have changed so greatly in the past several years, but they certainly have.
The problem is that some of the older installations (like many in New York City) have been passed on to new landlords or new owners and been forgotten about. The landlord might know there’s a sump pump in the basement of the school or hotel or apartment complex, but they might have no idea that it could cost them a huge fine for noncompliance!
This is an instance where calling in a sump pump repair company would prove beneficial. Not only can they save you from a potential fine, but it’s also beneficial to the environment to get it rerouted.
The reason that it’s no unlawful for sump pumps to be routed to sanitary sewers is the potential risk of overwhelming the municipal sewage treatment system. If your sump pump is routed to a basement sink, it is likely that it is heading directly toward the sanitary sewer system.
If you find this to be the case, you should call a sump pump repair company immediately to help you change this problem!
