Hot Water Complaints We Diagnose in Markham
Half of what we are called about here turns out to be capacity or distribution rather than a broken heater.
Hot water runs out when two showers run together
Usually not a fault. A single 50 gallon tank has a fixed recovery rate, and two simultaneous draws exceed it. We measure the actual recovery against your peak demand and talk through a larger tank, a second unit or a tankless before you replace anything.
Long wait for hot water at the far bathroom
This is distribution, not the heater. In a large Markham home the run to an ensuite can hold a lot of cold water. A recirculation loop or a demand-controlled pump fixes it. Replacing the tank does nothing.
Recirculation pump failed or was never balanced
A dead pump presents exactly as slow hot water. So does a pump running against a badly balanced loop. We test the pump, the check valve and the aquastat rather than guessing.
Recirculation is driving up the gas bill
A loop on a permanent timer keeps reheating water nobody is using, and it also accelerates anode consumption by keeping water moving. We switch it to demand or occupancy control.
No hot water at all
We check gas valve, thermocouple, igniter and pilot assembly, or elements and thermostats on electric units. Most finish in one visit.
Sediment noise or a leaking tank
We flush and check the anode, and we separate a real tank rupture from a valve or fitting leak before recommending replacement.
Markham Neighbourhoods We Cover
Markham has an unusual concentration of large homes with three or more bathrooms, a primary ensuite well away from the mechanical room, and in many cases a recirculation loop. That combination produces hot water complaints that no amount of repair work will solve, because the equipment is working and the demand simply exceeds it.
Markham Water Heater Repair FAQs
Two of us shower at the same time and the hot water runs out. Is the heater broken?
Probably not. A tank has a recovery rate, meaning the gallons per hour it can reheat, and two simultaneous showers can draw more than that. The tank empties faster than it refills. That is a capacity mismatch, not a fault, and the fix is more capacity rather than a repair. We measure your recovery rate and peak demand so the recommendation is based on numbers.
Why does the ensuite take so long to get hot when the kitchen is instant?
Because the pipe run is longer and it is full of cooled water that has to be pushed out before hot water arrives. In a large home that can be a lot of water. A recirculation loop keeps hot water near the fixture and removes the wait. This is a plumbing distribution issue and no water heater repair will change it.
Is a recirculation pump worth running all the time?
No. A pump on a permanent timer reheats water nobody is drawing, which costs gas and keeps water moving past the anode rod, consuming it faster. Demand control, where the pump runs when someone actually calls for hot water, gives you the convenience without either penalty.
Should I move to tankless for a big Markham house?
It genuinely suits high simultaneous demand, because it does not run out the way a tank does. The two things to check first are gas supply, since a tankless unit needs considerably more input than a tank and the existing line may be undersized, and venting. We check both before quoting rather than after.
Do you cover Unionville, Cornell and Cathedraltown?
Yes, along with Milliken, Berczy Village, Buttonville, Angus Glen and the rest of Markham. Same-day repair with no residential overtime surcharge.
