Water Heater Repair, Replacement & Installation

No hot water is the plumbing problem nobody can ignore for long. PHD Plumbing, Drain & Well Service repairs, replaces and installs water heaters across Alliston, Barrie, Innisfil and Simcoe County: conventional tanks, power-vented units, tankless systems and the boilers behind indirect tanks. Our licensed plumbers carry the common elements, thermostats, valves and gas parts on the truck, so most homes have hot water again the same day, and we answer emergency calls 24/7.

Pricing: Diagnosis is free. Our weekday service call is $45. After-hours and weekend calls are billed at a higher rate, and we tell you the price before we start any work.

Signs your water heater needs repair or replacement

• No hot water, or hot water that runs out far sooner than it used to
• Water that is lukewarm, or swings between hot and cold
• Popping, rumbling or banging from the tank (sediment build-up)
• Water pooling under the tank, or dripping from the relief valve or fittings
• Rusty or discoloured hot water, or a metallic smell
• A pilot light that keeps going out, or an error code on a power-vented or tankless unit
• A tank that is more than 10 to 12 years old, even if it still works

Water heater repair

Most no-hot-water calls come down to a failed heating element, thermostat, thermocouple, gas valve or igniter, and those are same-day repairs. We also fix leaking drain valves and relief valves, replace anode rods to stop tank corrosion, flush sediment that causes noise and lost capacity, and diagnose venting and combustion problems on gas units. If the tank itself has failed, we will tell you honestly that repair is not worth it and quote a replacement.

Water heater replacement and new installation

When it is time for a new unit we help you choose between a conventional tank, a power-vented tank, a tankless (on-demand) heater or an indirect tank on a boiler, based on how much hot water your household uses, your fuel type and where the unit sits. Every installation includes:

• Sizing for your home: number of bathrooms, occupants and peak use, so you do not run out or overpay for capacity you will never use
• Removal and disposal of the old unit
• New shut-off valves, flexible connectors, drain pan and thermal expansion tank where required
• Gas, venting and electrical connections to code, with the permit and inspection handled
• Full leak, pressure and temperature testing before we leave
• A walkthrough of the controls, the shut-offs and the maintenance schedule

Tankless water heaters

Tankless units heat water only when a tap opens, so they never run out and use less energy than a tank that keeps 40 gallons hot around the clock. They cost more up front, need adequate gas supply and venting, and require annual descaling on hard well water. We install, service and descale tankless heaters, and we will tell you plainly whether one makes sense for your home or whether a high-efficiency tank is the better buy.

Water heaters on well water

Hard water and iron shorten a water heater’s life. Scale insulates the element or burner, sediment fills the tank, and the anode rod is consumed faster. If you are on a well, we check hardness during the visit and can pair the heater with a water softener or filtration so the new unit lasts.

Water heater FAQs

How long does a water heater last?

A conventional tank lasts 10 to 12 years on municipal water and often less on hard well water. Tankless units last 15 to 20 years with annual descaling.

Can you replace my water heater the same day?

Usually. Common tank sizes are on the truck or a short drive away. Tankless and power-vented units are typically installed within a day or two.

Should I repair or replace?

If the tank is under 8 years old and the problem is an element, thermostat or valve, repair. If the tank is leaking, rusting or over 10 years old, replacement is the better investment. We give you both prices.

Do you handle rental water heater buy-outs?

Yes. We remove rental units and install one you own, and we can walk you through the numbers on rental versus purchase.

Do you install tankless water heaters?

Yes, gas and electric. We confirm your gas line and venting can support one before you buy.
