Fire Main & Water Supply Installation Services

Building a new property or upgrading an old water line? Everest Drain & Plumbing has been providing fire mains and water supply installation services in the Toronto and GTA area since 2013. A fire main supplies your building’s sprinklers and standpipes and a robust water supply keeps everything else running. We size, install, and connect both to the code from the city main to your riser. Call us for fire main and water supply installation across the Greater Toronto Area.

The Water Lines That Keep Your Building Running and Protected

Underground Water Work Done Right the First Time

Fire mains and water services are underground and have heavy demands; therefore, there is no room for shortcuts. Since 2013, we have installed and replaced water lines throughout the GTA using trenchless methods when suitable, avoiding damage to your property. This is just one of our comprehensive HVAC services throughout the area.

  • Licensed and insured team: fire main piping services from people who know the code and the city’s rules.
  • Trenchless where possible: we install and replace mains with less digging and less mess.
  • Correct sizing every time: we match the pipe to your building’s fire flow and water demand.
  • Permits and approvals handled: we deal with the city and the water authority for you.
  • Backflow and valves done right: we protect your supply and pass inspection.
  • One team, whole job: excavating, piping, connecting, and cleaning at one site, all under one roof.
  • Clear pricing up front: a clear quote before we begin, with no hidden fees.

Why Fire Main and Water Supply Work Is Specialized

A fire main is a pipe dedicated to supplying water to your fire protection system. A water supply line brings water to your building that you use every day. Both are connected directly to the municipal main and contain pressure that requires the correct pipe, valves, and backflow protection. If you get the size or connection wrong, the sprinkler will go dry or the pressure will drop. This work must be done in compliance with fire and plumbing codes and requires a licensed crew with experience. Each line is designed, installed and tested to last decades.

When Your Building Needs a New or Upgraded Main

In some buildings, a new main is required and in others an upgrade to meet demand. We install and replace mains across the GTA for a range of reasons:

  • New buildings require a fire main and water service installation from scratch
  • A renovation or addition that adds sprinklers or fixtures
  • An old water line (either lead or galvanized) that must be replaced
  • Low water pressure due to corrosion or an undersized main line
  • A new fire protection system specified by code or your insurer
  • A failing underground main that leaks or keeps breaking

Not sure which of these matches your building? We visit the site and tell you straight away.

Fire main and water supply installation services for residential, commercial, and industrial buildings.

What a Fire Main Installation Involves

The fire main installation is more than just a pipe in the ground. We provide you with all the work from the city connection to the feed that reaches your sprinkler riser. The following is a typical underground fire main installation:

  • The city connection: we tap the municipal main and set the shutoff and isolation valves.
  • The buried pipe: ductile or approved pipe laid according to your fire flow.
  • Backflow prevention: we install a backflow preventer to ensure that fire water does not flow into your drinking water supply.
  • The fire department connection: we install the FDC so crews can boost the system.
  • Thrust blocks and supports: we hold the line against the pressure it carries.
  • Testing and flushing: we pressure-test and flush the main before it goes live.

All fire main pipe installations include testing and paperwork required for sign-off.

The Above-Grade Fire Service Line

The fire main does not stop at the foundation. Where the line rises into the building, the work stays just as demanding. We install the above-grade side of your fire service, from the point it leaves the ground to the riser that feeds every floor. Here is what that covers:

  • The riser connection: we tie the buried main into your sprinkler and standpipe risers.
  • Above-grade valves: control valves, check valves, and test-and-drain assemblies, all supervised.
  • The backflow assembly: a room-mounted preventer sized and set for inspection and annual testing.
  • Standpipe risers: vertical piping and hose connections run to each floor and stairwell.
  • The fire department connection: above-ground FDC piping crews use to boost the system.
  • Interior fire main piping: large-diameter pipe braced and hung to carry full fire flow.

This is heavy pipe under real pressure, held to the fire code and signed off on inspection. It sits outside what a residential plumber takes on, and our licensed crew handles the buried run and the building side as one job.

Water Supply Installation for the Whole Building

Your water line supplies all the water taps, fixtures and appliances in the building. For new construction or upgrades, we install water supply services in your building to meet the demands of your property. A tired or old pipeline will cause a loss in pressure and will have rusty water and poor flow. We run a new service from the city main, fit a meter and backflow preventer, and install the main shutoff where you can reach it. Once the water supply system is installed correctly, you will have a strong and clean flow and our plumbing services will take care of all that comes after.

Not Sure What Your Building Needs?

You don’t need to have a complete specification before calling. Tell us about your building and your project, and we’ll take it from there. We evaluate the site, inspect existing lines, and plan out what the fire and plumbing codes require. No jargon, no upselling, and a clear plan and an honest quote.

Working to a Construction Deadline?

A water line that delays your construction can cost you both money and time. Everest plans and directs the work throughout the GTA while working with other trades to ensure the project keeps moving. Give us a call, and we will arrange the dig, permit and connection around your schedule. We have been working in the GTA since 2013 and we know how to stay on track.

How We Install Your Main, Step by Step

Every fire main and water supply installation follows the same clear steps, so you always know what to expect.

  • Assess and design: we size the line and design the route to your building.
  • Permits and approvals: we handle the city and the water authority.
  • Dig and connect: We cut, lay and connect the pipe.
  • Test and restore: we pressure-test, flush the line, then backfill and clean up.

What Fire Main and Water Supply Installation Costs

Cost depends on the length of the run, the pipe size, and how deep we dig. A short water service costs far less than a long fire main with valves and a backflow assembly. You get an upfront quote before any work starts, so nothing on the bill catches you off guard. Everest gives a free estimate over the phone or with a site visit, and every job is priced fairly for the work it takes.
The cost will vary depending on the run length, size of the pipe, and depth of digging required. Short water service lines cost much less than long fire mains with valves and backflow devices. Before any work commences, you’ll have an initial quote of the total cost of the services, which means no surprises on your bill. Everest provides free quotes via phone or by visiting our site. Every job is charged at a fair rate according to its requirements.

Frequently Asked Questions

  • 1. What is a fire main?

    The fire main is the pipe responsible for carrying water to the fire protection system in the building. This includes fire sprinklers and standpipes, running from the city main to your riser, typically buried.

  • 2. Do you handle the permits and city approvals?

    Absolutely. We take care of everything – the city, water authority, permits, and inspections. You don’t have to run around with all the paperwork.

  • 3. Can you install a new main without tearing up my whole property?

    Often, yes. Depending on the site, we can use trenchless technology that requires less digging. There are cases where we have to use open excavation, and we restore the site afterward.

  • 4. Will a new water supply line fix my low pressure?

    Most often, it helps a lot. Low pressure, in most cases, is the result of an outdated or small pipe. With a properly sized service installed, you’ll get a high flow.

  • 5. How long does a fire main installation take?

    For a small one, it takes a couple of days. Installation of a large fire main line with valves and tests takes more time. We provide the schedule in advance.

Very disappointed with my experience. I was charged what I felt was an excessive amount just to be told my water tank had failed. No repair was completed, yet the bill was still very high.

When I questioned the charge, I was told I had “already received a deal” because I had previously used Everest Plumbing for a flood. That response was disappointing and didn’t justify the cost.

To make matters worse, during the previous job I had arranged for my property management to shut off the building’s main water supply for the scheduled work, but Everest Plumbing never showed up. It wasted everyone’s time and caused unnecessary inconvenience.

I won’t be using them again.

Big thanks to Mr. Nimesh. He really saved me and my home from almost flooding the basement. Nimesh was quick to snake the blocked drain, and later, with his camera inspection, he found that the blockage was caused by roots. He snaked and cleared out the roots. Everything is now working completely fine, and he showed his work through a camera inspection proving the roots were cleared after the snake. A big thank you to Mr. Nimesh for helping to calm down such a panic moment.

First time working with Everest. Great experience! Was able to get a next morning appointment to fix our leaking sink. Plumber arrived on time, analyzed the problem, replaced a part, cleaned out the drain, tested everything, and cleaned up. The price was reasonable. Our new go-to plumber when we need one (not too soon please😉) Highly recommended.

Found Everest on Google after looking for someone to clean our drain line. Rajiv and Sandip appear as a team; their housekeeping was excellent. They cover and protect every aspect as needed. The work performed was clean and swift. They did power flushing until all the debris was clear time and again. Impress with their dedication toward work.
Great team, will use them again in the future.

Great Drain Cleaning and Flushing Service by Tenzin and Mr. Sandip, who well-communicated and was professional about all the work he did. Housekeeping was top-notch, from bringing tools in to keeping tools properly while working.
Everything was smooth from beginning to finish. No mess; leave the house as it was after completing snaking and flushing.

Tenzin came to fix a sump pump and check valve issue after a massive rainstorm. He worked hard to diagnose the complex problems and trial a few different solutions that fit the unique aspects of my house and property. His demeanour was very kind and calm and it was a pleasure to have him in our house. Great work!

Excellent service from Everest Drain & Plumbing. They are a family-owned business and Indra arrived promptly for a service call on the weekend, even though he works weekdays, to fix my clogged drain. They were very efficient and courteous. Indra assessed the situation in a timely manner and fixed the issue quickly without making any mess. Definitely knows his work, and I highly recommend them if you're looking for a local plumber. Thanks, Indra. Great work!!!

I had a pipe burst a few days ago and contacted several companies, but Everest Drain and Plumbing was the only one that could clearly confirm how soon they could attend to the issue. They offered me a 9:00 AM appointment the following morning and arrived right on time — even a bit early.

I truly appreciated the prompt response, professionalism, and fair pricing. The service was efficient, and everything was handled smoothly.

I would definitely choose Everest again for any future plumbing needs.

Thank you, Everest, for your excellent and reliable service!

I had a pipe burst a few days before Christmas - tis the season. Out of the companies that I contacted, Everest was the only company that could confirm how soon they'd be able to attend to the issue. They offered an appointment for 9am the following morning and Indra was prompt, if not early.

We were very appreciative with his service, and I would go directly with them for future plumbing issues/needs.

Thank you Indra and Everest for your prompt service and pricing.

Our main drain was cracked. From the moment we called Everest Drain the service has been exceptional. Indra was very professional and honest, the work they performed was very clean as they had to dig a finished basement. They did not make a mess and finished the job on time. I have no hesitation in recommending this company.

I recently had the pleasure of working with Everest Drain & Plumbing in Toronto, and I could not be more impressed with their exceptional service! From the moment we called them for assistance with plumbing work, I knew it was in good hands. Aly was punctual, with something we always appreciate. Not only professional but also incredibly knowledgeable about the problem. He explained in detail and made me understand before moving forward. The work was completed with the highest level of craftsmanship. One of the standard aspects of Everest Drain & Plumbing is their fair and upfront pricing. The pricing was reasonable for the quality of work provided, and I appreciated their transparency. What truly sets them apart is their outstanding customer service. Aly made sure to clean up after all the work completed, and there were no surprises when the work was done. I was overall impressed by how well Aly managed the entire process from diagnosing to resolution. If you are looking for a trustworthy, skilled and professional Plumbing company look no further. They have earned a loyal customer in me!
