A Water Main Break Near the Passaic River Kept Fair Lawn Under a Boil Water Advisory for Two Days

A break at 542 Wagaraw Road cut water or pressure to parts of Fair Lawn on August 10 and triggered a boil water advisory that stuck around through Wednesday afternoon. The physical fix was fast. Confirming the water was actually safe again took almost two full days, and the borough's own reopening checklist is a reminder that clearing an advisory and trusting your own pipes again are two different things.

What Happened at 542 Wagaraw Road

On Monday, August 10, 2026, a water main break near the Passaic River at 542 Wagaraw Road left some Fair Lawn customers without water entirely and others with a significant drop in pressure. By around 3 p.m. that afternoon, the borough had issued a precautionary boil water advisory covering its service area while crews worked to isolate and repair the break.

The advisory itself was standard for this kind of disruption. Any water used for drinking, cooking, brushing teeth, washing produce, making ice, or mixing baby formula needed to be boiled for a full minute first, or residents could use bottled water instead. A sudden loss of pressure like the one Fair Lawn saw can let contaminants into the system at the exact moment water is trying to force its way back through the pipes, which is why utilities default to the advisory rather than waiting to see if anything actually went wrong.

Why the Advisory Outlasted the Repair by a Full Day

Fair Lawn's crews had the actual break on Wagaraw Road fixed by Tuesday morning, less than a day after it was first reported. That is a normal turnaround for an isolated residential main. But the boil water advisory did not lift with the repair. It stayed active through a full second day while the water system was flushed and tested, and it was not until Wednesday, August 12 around 2:30 p.m. that the borough confirmed water quality had cleared and lifted the order.

That nearly two-day gap between the pipe being fixed and the advisory being lifted is the part that catches people off guard. A physical repair only stops new contamination from entering the system. Confirming that the water already sitting in the pipes, both the borough's and every home's own interior plumbing, meets safety standards takes lab turnaround time that a wrench cannot speed up.

The Five Things Fair Lawn Told Residents to Do Before Trusting the Tap Again

When the advisory lifted, Fair Lawn's water department did not just say the water was clear and leave it there. It published a specific five-step checklist: run faucets for three to five minutes to flush the service line and interior plumbing, empty and clean any automatic ice maker or water chiller, drain and refill a hot water heater if it is set below 113 degrees, run water softeners or cartridge filters through a regeneration cycle, and drain and refill any rooftop or building water reservoir.

Those steps exist because stagnant water sitting in a home's own pipes, heater tank, or softener resin bed for two days is a different problem than the water main itself. Skipping them means the first glass out of the tap after the all clear can still carry sediment or trapped air, even though the citywide testing came back clean.

What This Means for Any NJ or PA Home After a Main Break

Fair Lawn's situation was specific to Wagaraw Road, but the pattern applies anywhere in New Jersey or Pennsylvania a main break triggers a boil water advisory. The utility's job stops at confirming the water entering the system is safe again. Whatever happened inside a specific house's own plumbing while the advisory was active, a water heater that sat unused at a cooler temperature, a softener that stopped regenerating, a dishwasher line full of stagnant water, is not something the borough's testing checks.

For homeowners or small businesses that went through an advisory, running through a version of Fair Lawn's checklist is worth doing even if the local water department did not spell one out. Plumbarama's licensed technicians can flush a water heater, check a softener or filtration system, and confirm pressure and water quality at the fixture level, on a 24/7 basis, for anyone who wants a second check after service comes back.

6 Things to Check After Any NJ or PA Boil Water Advisory Lifts

Fair Lawn's five-step checklist is a good starting point after any advisory, in any town. Here is the fuller version for a homeowner or small business owner.

1. Flush your faucets first, before you drink anything: Run cold water at every faucet for three to five minutes to clear stagnant water and sediment out of the service line and interior plumbing before using it for anything else.
2. Empty and clean ice makers and water chillers: Any ice made during the advisory should be discarded, and the ice maker's reservoir should be emptied and wiped down before it makes another batch.
3. Check your water heater's temperature and refill it: If the tank is set below 113 degrees, drain and refill it. Stagnant water sitting in a lukewarm tank for two days is exactly the kind of thing a boil advisory is meant to guard against.
4. Run water softeners and filters through a full regeneration cycle: A softener or cartridge filter that sat idle during the advisory needs to cycle through per the manufacturer's instructions before it is treating water normally again.
5. Drain and refill any building or rooftop water reservoir: This mostly applies to apartment buildings, schools, and commercial properties, but any tank that stores water separately from the main line needs its own flush.
6. Call a plumber if pressure or water quality still looks off: If water still runs cloudy, discolored, or low pressure a day after the advisory lifts, that points to something local to the property rather than the water main, and it is worth a professional look.

Frequently asked questions

Do I need to boil water even after the advisory is lifted?

No. Once a utility lifts a boil water advisory, testing has confirmed the water meets safety standards. The follow-up steps, like flushing faucets and refilling a water heater, are about clearing stagnant water from a home's own pipes and appliances, not about ongoing contamination risk.

Why did the advisory last almost two days if the break was fixed overnight?

Repairing the physical break only stops new contamination from getting in. Confirming the water already in the system is safe requires lab testing of water samples, which takes time a repair crew cannot speed up.

Is a water heater damaged by sitting through a boil water advisory?

Not typically, but water that sat in the tank for an extended period at a cooler than usual temperature is worth draining and refreshing, especially if the thermostat is set below 113 degrees, which is why utilities include that step in their post-advisory checklists.

Who do I call if my water still seems off after the advisory lifts?

For anything traced to the water main itself, contact the local water department. For issues specific to a single home, like a water heater, softener, or fixture that is not behaving normally after the advisory, a licensed plumber like Plumbarama is the right call, available 24/7 across New Jersey and Pennsylvania.
