There are a number of reasons why a property owner would be required to install a new fire sprinkler or combined water main. The most common reason would be if you are being required to install a new main by DOB. In this case you are most likely renovating the property or building from the ground up.The rules and requirements for installing new fire sprinkler mains are constantly changing, for this reason we always suggest that you consult with your architect to determine the exact details your project is going to require.
Another common reason would be if your existing fire sprinkler main is leaking. In this case the replacement would be completed on an emergency basis. It is important to understand the DEP regulations and requirements even if you are replacing an existing main. Depending on the size of your water main you may be required to upgrade the size, even if it is an existing sprinkler main that has been in the building for over 50 years.
Requirements for all fire sprinkler & combined water main installations
The installation of all water mains feeding a fire sprinkler system are required to obtain a DEP inspection. Once scheduled a DEP inspector will arrive on-site to inspect each section of piping before the excavations are back-filled. All fire sprinkler mains are required to have a curb valve installed on the sidewalk and an OS&Y valve installed on the inside of the building. The inspector is required to inspect the piping installation and confirm that that piping is installed per the DEP code. The inspector will also confirm that the piping is installed in accordance with the approved plans.
Installation & Permits in NYC
Our installation division features a staff of experienced field supervisors and crew members who will oversee the entirety of your project. After over 100 years of proving ourselves in the field, our sprinkler installations and repairs have garnered us a reputation of being the most competent fire sprinkler specialists in the industry. When working on filing for NYC, DOB & DEP permits for a new sprinkler or combined system, there are two sets of approved plans that the licensed plumber is required to submit for DEP to review prior to releasing permits.
A DOB (Department of Buildings) approved plan showing the sprinkler service, water meter and/or check valve.
The cross connection letter which is the DEP approval for your Backflow Prevention Device.
Does your Fire Sprinkler System require a tap or a wet connection on the city main?
If you are installing a new 2”copper main or anything smaller in size, you will be required to install the same size tap connection on the city main. This differs from a domestic water service where the tap connection would be one size smaller than the pipe. In most cases when installing a new 3” ductile iron sprinkler service or larger, you will be required to install a wet connection of equal size to the pipe unless approved plans state otherwise. Example: A 3” ductile iron pipe would require a 3” wet connection to be connected to the city main. The only exception to these rules would be if the contractor is making a repair to a existing 2.5” or 3” sprinkler main that was previously hooked up to a 2” tap connection. In this case the contractor would re-connect back to the existing 2” tap on the city main.
What is a Backflow Prevention Device and why are they required?
Backflow prevention devices prevent contaminated water or chemicals from flowing backwards into the public water system from the fire sprinkler system. Certain types of business that are more prone to contaminated water and most buildings with a sprinkler system require a backflow prevention device. Backflow Prevention Devices are an essential piece of the “New York City Department of Environmental Protection’s Drinking Water Protection Program”. Backflow Prevention Devices are now mandatory under the “New York State Sanitary Code and the Rules of the City of New York” for any businesses that may serve as a risk to public water supply.
Recently had to deal with a broken sewer for my elderly parents after receiving a city violation. Harris came in and did not try to sell me an entire new sewer like others. They were professional, very fairly priced and got the job done quickly!read more

Recently became aware of a sinkhole in front of my house and determined that my sewer line was broken. I reviewed and met with a few companies to gain a better understanding of what was needed. I am happy to have met Mike Kayne from Harris. He was patient with all of my questions, didn't try and force me into a quick decision like others. And most of all he actually gave me a cost effective option to repair a section of my pipe which nobody else did. After further explaining the risk with this I decided to replace the entire sewer line but did feel a level of comfort just for the fact that Mike gave me the option. He also advised on all variables to take place during the installation process. One week later my new sewer is installed and running well!Thank you to Mike, Millie and the entire staff for handling my situation like professionals.read more

Recently used Harris Sewer after my insurance company denied a claim for my broken sewer. They claimed the pipe was back pitched and not covered under warranty. I received several estimates from private firms who were all trying to either sell me an entire new sewer or trying to charge me an exorbitant amount of money.Finally I was referred to Harris who advised that they could repair just a section of the pipe if we were able to identify where the back pitch was located which was later provided by the insurance company.Long story short, the work was completed with a DEP inspection and all in one day. Thank you Harris Sewer!read more

I was on the brink of disaster two days ago when my water main cracked and water was leaking back into my house. I called Harris who calmly walked me through the process to completing the work and even better, had the worked completed the very same day. I really want to thank the entire staff for being so professional when I may have been excited and keeping composure. Thank you!!read more

Before I moved into my house in Brooklyn 5 years ago, the inspector advised me to replace the sewer and water lines going from the street to the house. (At that time, it still had the original lead water pipe from 1902, when the house was built!) I'm so glad that someone referred me to Harris. They did a most excellent, totally professional job. This is not one of those fly-by-night companies (so prevalent in Brooklyn) that are more intent on avoiding paying their business taxes than on doing a good job. It was amazing to see, but this company does this every day and they really know their stuff! I recommend them without reservation.read more

We had a broken sewer pipe. From the very beginning they were very professional. They came out and gave us a quote. They called to schedule a day for the job. They showed up on time and got the job done. They came back at a later date and repaved the road in front of our house. I was impressed when they followed up with a thank you for service and a copy of our full paid invoice. I did not expect this type of treatment. Usually after the job is done the consumer usually hears nothing from the business. Overall, I am satisfied with the job. I only pray that where they replaced will not have any future problems.read more

These guys were on point and worked on my property super quick. I had a main pipe coming from the street going into the property break down on a HOLIDAY 3 DAY WEEKEND. These guys filed for city permits asap and worked on my property efficiently. The whole team was very professional and courteous. If I ever need help again, I'll be reaching out to them for sure.read more

I received a 3 day notice from DEP and contacted Harris Water Main. They were recommended by a close friend that works with the city. Harris immediately put me at ease and said they would take care of everything. They got all the permits and did the work within the 3 days. I would definitely recommend Harris Water.read more

I was fairly upset when I got a 3-day notice from the city about my leaking water main, in fact i really didn't know what to do. I called my regular plumbers, but they said they weren't equipped to do this job. Thankfully they referred me to Harris. We quickly got an appointment scheduled for them to come out and take a look. Once I got the estimate and paid the deposit, they took over, getting all permits and applications, handling the 3-day notice, etc. I didn't need to lift another finger. The job itself was big and messy and loud, but I don't think there's any other way to repair something buried in the sidewalk and your driveway. I was impressed with their speed and efficiency. They got here first thing in the morning and the primary job was done before close of business. Two other crews came by in the following days to do the final repair on the road and my driveway. In all, getting the notice was super stressful and no one likes to pay a bunch of money out of the blue, but given that there was no way out except to fix it, Harris gave me a ton of peace of mind and took the job completely off my plate. I would definitely use them again.read more

When I got a three day notice from the city, I knew that I needed to find someone who could come ASAP to fix the issue or else the water would be shut off. I turned to Harris water main and Sewer contractors for help. They came within a few days to assess the site and the problem and sent a team to come fix it pretty soon. They finished the job pretty quickly and cleaned up any residue from the work and made it look just like before the construction took place. I am really grateful for Harris to be able to come as soon as they did and in doing such a great job.read more
