Commercial Plumbing vs. Residential Work

A house has one family using a couple of bathrooms and a kitchen. A commercial building might have dozens of people using the same restroom every hour, a kitchen dumping grease into the drains all day, and tenants on the other side of the wall who lose business if the water gets shut off. The pipes are often bigger, the fixture counts are higher and the stakes are different when something fails.

The rules are different too. Commercial plumbing in Florida is built and inspected under the Florida Building Code, Plumbing, and the local building department reviews the work before it’s covered up. Bigger commercial jobs can require plans from a design professional. Lee County, for example, requires one when changes to the water supply or drainage system reach a certain project value or fixture unit count. Our residential plumbing work follows the same code book, but commercial jobs usually carry more paperwork, more inspections and more people to coordinate with.

Then there’s the schedule. At a home, a shutoff is an inconvenience. At a restaurant or a dental office, it’s lost revenue. So a lot of what we do on commercial jobs is planning: when to shut water off, who needs notice, and how to get the building back in service with as little downtime as we can.

Plumbing Needs by Property Type

Every building type wears its plumbing out differently. Here’s what we tend to see around Southwest Florida.

Offices and professional suites

Offices are usually light on water use but heavy on restroom traffic during business hours. Common calls are running toilets, sticking flush valves, slow break room sinks and small leaks at supply lines that go unnoticed over a weekend. Most of this is straightforward plumbing repair work that we can schedule before or after the office opens.

Retail storefronts

Retail spaces often have one or two restrooms and a utility sink, sometimes sharing a sewer lateral with the neighboring units. When one tenant’s drain backs up, it can be a shared line problem, not a problem inside that unit. Figuring out where the blockage actually is saves arguments between tenants and the landlord.

Restaurants and food service

Kitchens are the hardest-working plumbing in any commercial building. Floor drains, prep sinks, dish machines, mop sinks and hand sinks all run constantly, and grease is always working its way into the lines. We cover the grease side in more detail below.

Medical and dental suites

Medical and dental offices add hand sinks in every operatory or exam room, sometimes specialty equipment connections, and a lot of fixtures packed into a small footprint. These suites usually come up during build-outs, when a former office space gets converted and needs new supply and drain lines run to each room.

Salons and barbershops

Shampoo bowls push hair and product into the drains all day. Hair traps help, but the lines still need regular attention. Salons also use a lot of hot water, so water heater sizing matters more here than in most small retail spaces.

Warehouses and flex space

Warehouses tend to have long runs of pipe, a restroom or two and maybe a small office. Problems often come from age and neglect: corroded supply lines, a water heater nobody has looked at in years, or a floor drain that’s dried out and letting sewer gas into the space.

Multifamily and condo buildings

Apartment and condo buildings run on shared risers, the vertical supply and drain stacks that serve units stacked on top of each other. A leak or clog in a riser affects several units at once, and repairs usually mean getting into more than one unit.

HOA clubhouses and amenity buildings

Clubhouses, pool bathrooms, fitness centers and outdoor showers see heavy seasonal use, then sit quiet. That on-and-off pattern is hard on fixtures and valves.

Restaurant Drains, Grease Interceptors and FOG Rules

Fats, oils and grease (usually called FOG) are the biggest plumbing problem for food service. Grease goes down the drain warm and liquid, then cools and sticks to the inside of the pipe. Over time it builds up until the line slows or stops. When it gets into the public sewer, it causes blockages and overflows there too, which is why utilities regulate it.

Most food service operations need a grease interceptor or grease trap between the kitchen drains and the sewer. Local utilities in Southwest Florida run FOG programs that inspect food service establishments and set rules for how interceptors are maintained. Collier County’s program alone monitors hundreds of restaurants and food service sites. The details vary by utility, so check with the one that serves your building.

The 25% rule

Many FOG ordinances use what’s called the 25% rule. Inside an interceptor, grease floats to the top and solids settle to the bottom. When the grease layer and the solids layer together take up 25% of the liquid depth, the interceptor is considered full and needs to be pumped. Some utilities also set a minimum pumping schedule. Pumping and hauling is done by a licensed grease waste hauler, not a plumber, so keep your hauler’s records handy for inspections.

What we handle

Our part is the plumbing on either side of the interceptor. That includes the drain lines from sinks and floor drains, the piping into and out of the interceptor, and the building sewer downstream. When a kitchen line slows down, we clear it and look at why it’s happening. Our drain cleaning service covers kitchen lines, floor drains and main lines. If you’re remodeling a kitchen or adding equipment, our kitchen plumbing work covers new sink and equipment connections.

• Scrape plates into the trash before they go to the dish area.
• Keep strainers in floor drains and sinks and empty them.
• Don’t pour fryer oil or hot grease down any drain.
• Call us if the same line keeps backing up. Repeat clogs can point to a pipe problem.

Commercial Restrooms: Fixture Wear, Flush Valves and ADA Basics

A public restroom fixture might get used more in a week than a home toilet gets used in a year. Flush valves (the lever or sensor valves on commercial toilets and urinals) wear out their internal parts and start running on, short flushing or failing to flush. Faucets drip, sensor units lose power or calibration, and wall-hung fixtures can loosen on their carriers. We repair and replace these parts, and our bathroom plumbing page covers the kinds of fixture work we do.

ADA basics we build around

When a restroom is built or remodeled, the fixtures need to meet federal accessibility standards. A few of the plumbing-related basics:

• Accessible lavatories can’t be higher than 34 inches to the rim or counter.
• There has to be knee and toe clearance under the lavatory.
• Water supply and drain pipes under the lavatory must be insulated or otherwise configured so people can’t contact them.
• Faucet controls have to work with one hand, without tight grasping or twisting of the wrist.

We install to the designer’s layout. Getting the rough-in right before the walls close is a lot cheaper than moving it later.

Public handwashing sinks also need tempered water, usually delivered through a temperature limiting device, so nobody gets scalded at a hand sink. That ties into the water heater setup.

Water Heaters for Businesses

A small office might be fine with a single tank unit. A restaurant, salon or laundry facility needs a lot more hot water, often at different temperatures for different uses. Dish machines may need hotter water than hand sinks, and hand sinks need tempered water for safety. That can mean a mixing valve, a booster or more than one heater.

Sizing is the main question. An undersized heater runs out at the busiest part of the day. We look at the fixtures and equipment on the system, how the business actually uses hot water and the space and venting available.

Tankless units are a good fit for some commercial spaces, especially where floor space is tight or demand comes in bursts. They’re not the right answer everywhere, and multiple units are sometimes needed to cover the load. Read more about our water heater service and our tankless water heater installs.

Leaks and Water Damage in Shared Buildings

In a standalone house, a leak damages one owner’s property. In a strip center, office building or condo, water travels. It runs down through ceilings, under walls into the next suite and along slabs. By the time someone notices a stain, the source can be two units away.

That’s why finding the leak matters as much as fixing it. Our leak detection work helps pin down where water is actually coming from, whether it’s a supply line in a wall, a drain connection above a ceiling or a line under the slab. Knowing the true source also helps owners, tenants and associations sort out who’s responsible for the repair.

Some leaks come from old piping that’s failing in more than one place. If you’re patching the same building over and over, it may be time to look at replacing sections of supply line. Our water line repair service covers both spot repairs and replacement of damaged runs.

• Know where the main shutoff and any unit or floor shutoffs are, and make sure they actually turn.
• Label shutoff valves so tenants and staff can find them.
• Check water heater pans, ice machines and under-sink supply lines during routine walk-throughs.
• Take ceiling stains seriously. They rarely fix themselves.

Sewer and Drain Lines on Commercial Sites

Commercial sewer lines handle more flow and more abuse than residential ones. Paper towels, wipes, grease and hair all end up in them. Tree roots find their way into older clay or cracked lines, and settled or shifted pipe creates low spots where waste collects.

Cleanouts give us access to clear and inspect the line. If your property doesn’t have accessible cleanouts, or they’re buried under landscaping or paving, adding or exposing one makes future service faster. When a line is cracked, collapsed or bellied, cleaning only buys time. Our sewer line repair service covers repairing and replacing damaged sections along with cleanout installation.

Backflow Prevention and Cross-Connection Control

A cross-connection is any point where drinking water could come into contact with something that shouldn’t be in it, like irrigation water, chemicals, a boiler or a soda machine. Backflow happens when pressure changes let that water flow backward into the supply. Backflow prevention assemblies stop that from happening.

Florida requires community water systems to run cross-connection control programs. Under state rules, backflow assemblies on non-residential connections have to be tested after installation or repair and at least once a year after that. Utilities in our area, including Lee County Utilities, require testing by certified testers they approve, and they can shut off water service to properties that don’t comply.

Testing has to be done by a certified backflow tester. When a test fails or an assembly needs to be moved, replaced or reconnected, HomeFlow can repair and replace the plumbing around it. We also run the piping to new assemblies during build-outs and new construction. After any repair, the assembly has to be retested by a certified tester before it’s back in compliance.

Tenant Build-Outs and Remodels

Build-outs are some of the most common commercial plumbing jobs in Southwest Florida. A former retail unit becomes a dental office. A vanilla shell becomes a cafe. An office gets another restroom. Each of those means new fixtures, new drain and supply lines, and often cutting and patching the slab.

Build-out plumbing generally needs a permit from the county or city building department in Lee, Charlotte and Collier Counties. Depending on the size of the job, the permit may need plans showing fixture counts, pipe sizing, water heaters and backflow protection. Kitchens may also need grease interceptor details on the plans.

We work with general contractors, landlords and tenants on these projects. The GC usually runs the schedule, the landlord has rules about shutoffs and access, and the tenant wants to open on a certain date. We try to get those details up front so the plumbing rough-in, inspections and trim-out fit the overall schedule. Our plumbing renovations page has more on remodel work.

• Confirm where the existing sewer and water connections are before the layout is finalized.
• Check whether the landlord requires specific fixtures or shutoff procedures.
• Plan for slab work early. Trenching for new drains takes time and affects other trades.
• Build inspection dates into the schedule before drywall and ceilings go up.

New Commercial Construction Plumbing

On new construction, plumbing starts before the slab is poured. Underground drain lines, sleeves and stub-ups have to be in the right place and inspected before concrete. Then comes above-ground rough-in, water service, testing and finally setting fixtures and equipment.

We work off the approved plans and coordinate with the GC and other trades so the plumbing lines up with walls, casework and equipment. Our new construction plumbing page covers the phases of that work in more detail.

Planning Work Around Your Operations

Most businesses can’t just close for a day so the plumber can work. Planned work can often be scheduled around business hours, before opening, after closing or on slower days. A restaurant might need a shutoff between lunch and dinner. An office might prefer a Saturday.

Before a planned shutoff, it helps to know which fixtures and tenants are on the affected valve, how long the water will be off and who needs notice. In multi-tenant buildings, the property manager usually handles notices. We’ll give you a realistic time window so nobody gets caught off guard.

After a Storm: Flooding and Reopening Checklist

Hurricanes and tropical storms can push floodwater and storm surge into commercial buildings along the coast and in low areas inland. Floodwater can back up through floor drains, damage water heaters and equipment at ground level, and push debris into sewer lines. Power outages and pressure drops can also affect water service.

Before reopening after a storm, walk through the plumbing with this list:

• Follow any boil water notices from your utility before using water for drinking, food prep or ice.
• Check water heaters that sat in floodwater. Gas and electric components that got wet need to be looked at before use.
• Run water at each fixture and check for leaks, low pressure or discolored water.
• Flush floor drains and check for slow drains or sewer odors that may mean debris or a damaged line.
• Look at the backflow assembly and exposed piping outside for storm damage.
• Check grease interceptors for floodwater intrusion and call your hauler if needed.
• Document damage with photos before repairs for insurance purposes.

If you find leaks, backups or damaged equipment, call us to get it repaired.

Working With Property Managers and Associations

A lot of our commercial work comes through property managers and HOA or condo boards. They need clear answers about what failed, why, what it costs to fix and whose responsibility it is. We explain the problem in plain terms and put it in writing so the manager can share it with owners, tenants or the board.

For condo associations, plumbing is also a long-term planning item. Florida’s structural integrity reserve study requirements for condominiums list plumbing among the building components associations have to plan for. If a board is looking at aging risers or supply lines, it helps to understand the plumbing condition before budgeting.

We serve commercial properties across Lee, Charlotte and Collier Counties, including Fort Myers, Fort Myers Beach, Cape Coral, Bonita Springs, Naples, Lehigh Acres, North Fort Myers, Estero, Sanibel, Alva, Punta Gorda, Port Charlotte, Golden Gate and Marco Island. See our service areas, or visit our Fort Myers and Naples pages for local info.
