Hot water tanks: repair and replacement: No hot water, or a puddle under the tank

Cold showers and a wet floor by the tank can come from one worn part or from a tank that has given out. We find out which, then tell you if it's worth repairing or due for replacement. We work on both tank and tankless units.

What to watch for

Signs it’s time to call

  • Showers going lukewarm sooner than they used to
  • No hot water at any tap in the house
  • Water pooling around the base of the tank
  • Rust-coloured or cloudy water from the hot tap only
  • Rumbling or popping from the tank while it heats
  • A tankless unit that shows an error code or cuts out mid-shower

What we do

How we handle it

  1. Step 1: Test the heater first

    We check the heater and the pipes and valves around it until we know what has stopped working. A new tank doesn't come up until we've found the cause.

  2. Step 2: Fix leaks that aren't the tank

    Not every puddle means the tank is finished. A loose fitting or a worn valve can often be repaired on its own.

  3. Step 3: Replace a tank that has failed

    A tank that leaks from the shell can't be patched, so we take the old one out and put a new one in its place. Installations include the connection.

  4. Step 4: Tankless repair and installation

    We repair tankless heaters and install new ones. If you're thinking about moving from a tank to tankless, we'll talk through how it would suit your household first.

Before we get there

  • If the tank is leaking, close the cold water valve on the pipe that feeds it. If you can’t find that valve or it won’t turn, close your main water shut-off instead.
  • Switch the tank off at its own controls.
  • Hot water tanks often share a utility room with the electrical panel. If water is spreading toward the panel or an outlet, keep everyone out of the room.
  • Don’t lift the relief valve lever or try to drain the tank yourself. The water inside can be hot enough to scald.
  • If you smell gas, skip all of this. Leave the house and call your gas utility from outside.

Hot water tanks: common questions

Should I repair my hot water tank or replace it?

If a part has worn out and the tank is sound, a repair usually makes sense. If the tank itself is leaking or rusted through, replacing it is the only real fix. A heater that keeps needing parts is worth weighing against a new one.

Is a leaking tank an emergency?

It can be. A slow drip from a fitting is less urgent, but water coming from the tank itself, or any water near outlets or the electrical panel, needs dealing with now. Switch the tank off at its own controls and close the cold water valve that feeds it. We're open 24/7, so call or text whatever the hour.

Is a tankless water heater worth switching to?

For some houses it is, and for others a tank still makes more sense. A tankless unit heats water as it flows, so it doesn't run out the way a tank does, but it can only heat so much at once. If your household often runs the shower and the dishwasher at the same time, that matters. We'll look at your setup before recommending either.

What will a new hot water tank cost?

That depends on the tank and what the installation involves, so we quote after seeing it. The estimate is free, and you'll hear the costs before any work starts. Our work is covered by warranty. Coverage depends on the service, so ask us for details.
