Hot Water Tank Repair in London for Gas, Electric and Tankless Units

Hy-Pro Plumbing and Drain Cleaning handles water heater repair in London for gas, electric and tankless units. A tank that pops, leaks at the base or runs cold halfway through a shower usually points to one failed part. We find it with test equipment, then quote a flat rate before any work starts. Call our London plumber team at 226-289-1773, day or night.

What Does a London Water Heater Repair Visit Involve?

Water heater repair means tracking down the part that stopped your tank from heating or holding water, then fixing it so the unit runs safely again. Most calls in London come down to an element, a thermocouple, a gas valve or a venting fault. We start every visit the way our Cambridge plumber crews do: test first, replace parts second. No swapping parts on a hunch.

On an electric tank, we put a multimeter on each element and thermostat to check resistance. Gas units get a different routine. We test the thermocouple or flame sensor, look at the burner and pilot, read gas pressure with a manometer and confirm the flue draws. Power-vented tanks, which you’ll find in plenty of newer homes around Hyde Park and Lambeth built without a chimney, add a fan motor and pressure switch to the checklist. Ontario puts gas valve and burner work under Technical Standards and Safety Authority (TSSA) rules, so whoever adjusts yours needs a TSSA gas certificate.

Your water source plays a part too. The City of London reports about 85% of its drinking water comes from Lake Huron and the other 15% from Lake Erie. Both lakes carry dissolved calcium and magnesium, and heat pulls those minerals out of the water inside your tank. They settle as a crusty layer on the tank floor, which traps heat under the burner, makes the tank pop and rumble, and cooks lower elements early. A yearly flush keeps it in check.

Two smaller parts get a look on every visit. The anode rod corrodes on purpose to slow rust inside the tank, and once it’s eaten down to bare wire, the steel takes the hits instead. The temperature and pressure (T and P) relief valve opens at 150 psi or 99°C. A constant drip there usually means high system pressure or a worn seat.

Why Choose Hy-Pro for Your London Water Heater?

You get a plumber who averages about 10 years in the trade and a flat-rate price before work begins. Hy-Pro has served Southwestern Ontario for more than 25 years, with a London office at 380 Wellington Street and a home base in Cambridge. We’re family-owned, Canadian owned and operated, and about 50 people strong.

Experience shows up on small calls. A pilot that won’t stay lit usually points to the thermocouple. A power vent that trips on frigid January mornings often has frost built up at the vent termination outside.

At Hy-Pro, we inspect first and explain second. Most tanks last 8 to 12 years, so on an older unit we price the repair and the replacement side by side. Sometimes fixing a 13-year-old tank makes sense. Often it doesn’t, and we’ll tell you.

Timing helps here. Your heater works hardest in January and February, when the water coming in from the street is at its coldest and recovery time stretches out. An October or November check catches a weak element or a sooty burner before the first deep freeze. Financing through Financeit is available, subject to credit approval.

Frequently Asked Questions About Hot Water Tank Repair in London

How much does it cost to fix a water heater in London?

The price depends on which part failed and what type of heater you own, so we quote after diagnosis instead of guessing over the phone. An electric element swap sits at the lower end, while a gas control valve or power vent motor costs more. Natural Resources Canada puts water heating at 18% of residential energy use in 2020, so a tank limping along on a failing part also costs you on every bill.

What should I do if my hot water tank is leaking?

Close the cold water valve on top of the tank first. Next, set the gas control to Pilot, or switch off the breaker on an electric unit. A drip from the relief valve or a top fitting usually means a repairable part, while water seeping from the tank body means the liner has failed. If you smell gas, leave the house and call Enbridge Gas from outside. Plenty of London tanks sit in finished basements in Byron and Westmount, so lay down towels and move boxes off the floor.

How do I know if London’s hard water is damaging my water heater?

Listen for popping or rumbling while the burner or elements run. That noise comes from water trapped under mineral scale on the tank floor. The Municipality of Bluewater reported a hardness of 107 mg/L in January 2023 for water from the Lake Huron Primary Water Supply System, which also supplies the City of London. That works out to roughly 6 grains per gallon. Drain a few litres from the tank’s drain valve into a bucket. Grit or cloudy water means it’s time for a flush.

Will you repair a rental water heater in London?

It depends on who owns the tank. Rental contracts in Ontario usually put repairs on the rental company, and an outside repair could put you in breach of the agreement. Look for a company name on the tank’s sticker or a monthly rental charge on your utility bill. If it’s yours, we’ll test it and price the fix.

What other plumbing services does Hy-Pro offer in London?

Water heaters are one slice of our work across the city. Other common calls include:

  • Drain cleaning and hydro jetting
  • Sewer camera inspections and sewer line repair
  • Sump pump repair
  • Water softener installation
  • Toilet repair and faucet installation

Got a second problem? Mention it when you book, and the plumber can look at both on one visit.
