A dip tube swap on a Delta gas water heater is a smaller repair, usually within the general water heater repair ballpark rather than its own separate price line.

Quick answer
Dip tube replacement on a gas storage water heater in Delta generally falls within the general water heater repair ballpark of $150 to $650, based on current public market data and not a fixed quote, since the job is often bundled with draining and inspecting the tank at the same time. CANRO's technicians confirm the exact figure once they've verified the dip tube is actually the cause of your symptoms, because a broken dip tube can mimic other problems.

The dip tube is a plastic pipe that runs from the cold-water inlet down to near the bottom of the tank, so incoming cold water is delivered where it belongs instead of mixing straight into the hot water sitting at the top. When a dip tube cracks or breaks off — a known issue on some older plastic dip tubes from the 1990s and early 2000s, and something that can also happen from age or a bad batch of material — cold water dumps in near the top of the tank and mixes with the hot water on its way out, so you get noticeably lukewarm water even though the burner is working fine.
This is one of the more commonly misdiagnosed water heater symptoms, because homeowners often assume a burner or thermostat problem first. A technician tests it fairly quickly by checking outlet temperature against the tank's set point and, if needed, pulling the tube for a visual check.

A dip tube on its own is a minor, worthwhile repair on a tank that's otherwise in reasonable shape, since it's inexpensive relative to the rest of the appliance and fully resolves the lukewarm-water symptom. If the tank is already old enough that other components are also due, or if a technician finds tank corrosion while investigating, that changes the calculation — there's little point fixing a dip tube on a tank that's leaking or close to it. A straight assessment of overall tank condition, not just the one symptom, is what determines the right call.
Because Delta runs mostly on Metro Vancouver's soft regional water supply, dip tube failures here tend to be about the plastic material itself or age rather than mineral scale eroding the tube, which is more of a factor in hard-water regions. The exception is scattered private-well properties in the agricultural areas of South Delta, where harder water can accelerate wear on plastic components generally. Either way, this is a job any Technical Safety BC licensed gas fitter servicing your tank can quote and complete in the same visit.
This job is a good moment for a technician to also glance at the anode rod and drain valve while the tank is open for the dip tube swap, since all three are accessed from roughly the same area at the top of the tank. It doesn't change the price of the dip tube repair itself, but bundling a quick anode check into the same visit can save a separate service call down the road if the anode also happens to be due.
Safety note
Work on the water heater's internal piping and tank fitting touches the gas train or combustion side of the appliance and must be done by a Technical Safety BC licensed gas fitter. A dip tube swap itself isn't a combustion-side repair, but it's done on a gas-fired appliance and should be handled by a licensed technician. If you ever smell gas near the unit, leave the house and call FortisBC at 1-800-663-9911 from outside.
A technician checks the actual outlet temperature against the tank's setpoint; a thermostat issue usually shows consistently wrong temperature, while a dip tube issue shows hot water that fades fast.
Most residential tank water heaters use a plastic dip tube; a technician replacing one will match it to what your specific tank model requires.
Small fragments can lodge in aerators and showerhead screens, which is usually just a cleaning fix, though a technician can check if debris made it further into fixtures.
It requires draining the tank and disconnecting the cold inlet fitting, and since it's work on a gas-fired appliance, most homeowners have a licensed technician handle it.
No — a dip tube affects water temperature mixing, not pressure; low pressure usually points to a different cause that a technician would check separately.
