Before You Call: Know Where Your Shutoffs Are

Plumbing is the one trade where what you do in the first two minutes changes the size of the bill. Water running for twenty minutes into a ceiling is a different claim from water running for two.

Situation	What To Do First
Active leak or burst line	Close the nearest isolation valve if there is one, otherwise the building main. Then call. If you do not know where the main shutoff is, tell dispatch your building type and we will talk you through where to look while a technician is on the way.
Sewer backing up	Stop using every fixture in the building, including anything upstairs. Each flush and each sink adds to what is coming up through the lowest drain. Keep people out of the affected area.
Water near electrical	Do not enter standing water near panels, outlets or equipment. Tell us when you call, because it changes who we send and whether power needs isolating first.
No hot water	Check whether the heater has power or gas, and whether a mixing valve has been adjusted by someone. On gas units, check whether other gas equipment in the building is also out, which points upstream rather than at the heater.
Smell of gas	Leave the building and call your gas utility first, from outside. Do not operate switches or equipment. Call us after the utility has made the site safe.
Blocked drain, no overflow yet	Stop putting water down it and note whether other fixtures are slow too. One slow fixture is usually local. Several at once means the problem is in the main line, which changes what we bring.

Find your shutoffs before you need them. The most expensive plumbing emergencies are the ones where nobody could find the valve. If your building is under a maintenance agreement we exercise and tag the main and zone shutoffs so they work, and so your staff know where they are. See commercial plumbing maintenance.

Common Commercial Plumbing Failures

What the symptom usually indicates. This is direction rather than a diagnosis, since the same symptom can have several causes.

Symptom	Usual Causes
Multiple fixtures draining slowly	A restriction in the main line rather than at any fixture. Grease, scale, roots, a collapsed section, or a blocked vent. One slow fixture is local, several at once is the main.
Sewer smell with nothing broken	Almost always a dry trap on a floor drain that rarely sees water, or a failed trap primer. Occasionally a vent issue. Buildings chase this complaint for weeks; it is usually a five minute fix once someone identifies it.
Urinal or toilet running constantly	A worn flush valve diaphragm, a failed sensor or solenoid on automatic valves, or a fill valve that no longer shuts off. Cheap to fix and expensive to ignore, because it runs constantly onto your water bill.
No hot water or not enough	Failed heating element or gas valve, sediment reducing effective tank capacity, a failed recirculation pump leaving distant fixtures cold, a mixing valve out of adjustment, or simply demand outgrowing the equipment as the building changed use.
Low water pressure building-wide	A partly closed valve, a failed pressure reducing valve, a failed booster pump, scale in older galvanized piping, or a fouled backflow device. Sudden pressure loss is different from a gradual decline and points in a different direction.
Water stain on a ceiling	A supply or drain leak above, a condensate line from HVAC equipment, a failed drain pan, or roof water tracking along a pipe. Water travels along structure before it drops, so the stain is often nowhere near the source.
Pit flooding or pump not running	A seized pump, a stuck or fouled float switch, a tripped breaker, or a discharge line blocked or frozen. On duplex systems the second pump has often been carrying the load alone for months without anyone knowing.
Banging pipes on shutoff	Water hammer, from a failed arrestor, a fast-closing solenoid valve on equipment, or unsecured piping. It is not just noise. Repeated hammer stresses joints and is a legitimate cause of future leaks.

What Happens When You Call

Step	What We Do
The call	We ask what is happening, whether water is still running, whether it is contained, and what the building is. A sewer backup in a restaurant and a slow washroom drain in an office get very different responses.
Dispatch	Maintenance agreement customers get priority dispatch. If we already service the building, the plumber arrives knowing the layout, where the shutoffs are, and what has failed before.
Contain, then diagnose	On an active leak the first job is stopping water and limiting damage. Diagnosis comes after the building is safe, not while it is still filling.
Quote before work	Once we know what failed, you get the cost before the repair proceeds. If it is a repeat failure and repair is not the right answer, we will say so and quote the alternative.
Repair and report	The work is documented: what failed, why, what was done and what to watch. On insurance claims that written record is usually the first thing your adjuster asks for.

Commercial Plumbing Repair FAQ

Do you offer 24/7 emergency commercial plumbing?

Yes, at 519-354-9491, including weekends and holidays. Maintenance agreement customers receive priority dispatch and reduced after-hours rates.

My drain keeps blocking even after it is cleaned. Why?

Because snaking clears a channel through a blockage without removing what is coating the pipe wall. If a line blocks repeatedly, the answer is a camera inspection to find the cause, then hydro jetting or a repair. Repeat blockages in the same spot usually mean grease, roots, scale, a bad slope or a failed section of pipe.

Will I know the cost before work starts?

Yes. On an active leak we stop the water first, because that is what limits the damage, then diagnose and quote the repair for approval before proceeding.

Can you find a leak without opening walls?

Often. Water travels along structure before it appears, so the visible stain is frequently nowhere near the source. We locate first and open as little as possible, but on a concealed leak some access is unavoidable and we will tell you before we start.

Do you repair equipment installed by another contractor?

Yes. We repair commercial plumbing systems regardless of who installed them, and will document what is on the building so there is a record going forward.

Can you handle a repair without shutting the whole building down?

Usually, if the building has working isolation valves. That is one of the practical reasons we exercise and tag shutoffs on maintenance visits. In buildings where valves have seized, a small repair can require a full shutdown that would otherwise have been avoidable.

Do you work on gas piping and appliance connections?

Yes, with G1 and G2 licensed technicians. If you smell gas, leave the building and call your gas utility first from outside, then call us once the site is safe.

Do you handle HVAC and electrical emergencies too?

Yes, on the same number. That matters more than it sounds on plumbing calls, because a ceiling leak is often an HVAC condensate line and water near a panel is an electrical problem before it is a plumbing one. See commercial HVAC repair and commercial electrical.
