It seems that the Department of Buildings requirements are becoming ever so restrictive when it comes to fire protection, and all for good reason. Over the years the city is requiring separate water main pipes to be installed from the city main in the roadway, to protect a home in the event of a fire. Many developers and homeowners are not happy about this as the installation tends to be costly however, the restrictions are only to protect the people working or living in the building.
Installing a new sprinkler main or combined water main is a big project in the eyes of most property owners, when dealing with a licensed plumber, the process is straight forward. An experienced water main and sewer contractor should have the entire processed streamlined, all the way from obtaining the required DEP approved drawings, to installation of the actual piping. Once the licensed plumber has all of the required permits with DEP and DOT, he can schedule the DEP to install the new city connection and begin the roadway excavating.
On the first day the contractor begins excavating in preparation for the new DEP wet tap installation, which connects the new fire sprinkler main to the city main.

Once the wet connection installation is completed, the plumber will complete the excavation process from the roadway, to the foundation wall of the building.

This type of water main requires a curb valve to be installed and must be inspected by the DEP, along with the rest of the pipe and the OSY valve inside the building.

Once all inspections are completed, the roadway is back-filled with dirt and prepared for the final restoration.
