Water heaters give you years of notice. Almost nobody gets told what the warnings mean.
A unit doesn't fail at random. It corrodes on a schedule, loses capacity gradually, and produces a sequence of small symptoms — discoloured water at first draw, rumbling on the tank floor, hot water running out slightly sooner than it used to, a spent anode nobody has looked at — for years before the day it finally leaks.
Every one of those is a data point. Read together, they tell you roughly how much life is left.
But nobody reads them together, because each visit answers only the question that was asked. Something breaks, someone fixes it, and nothing gets said about what the rest of the unit looked like while they were standing there.
So the failure arrives as a surprise — on a cold morning, at a night rate, with no time to choose a replacement or plan the cost.
We tell you what we saw, not just what we fixed. Anode condition, sediment level, corrosion at fittings, and an honest estimate of where your unit is in its life.

Read individually, they're minor. Read together, they're a timeline.
Corrosion inside the tank, or a spent anode. If only the hot water is affected, the heater is the source. One of the earliest meaningful signals there is.
Sediment on the tank floor, with water boiling underneath it. That layer is insulating steel from the water meant to cool it — so it's both a symptom and an accelerator.
Sediment occupying tank volume, a failed dip tube, or a dead lower element. Capacity loss is measurable and gradual.
Heat passing through a deposit before reaching the water.
Pressure, temperature, or the valve — and worth resolving rather than watching.
Corrosion is visible outside long before it breaches inside.
The single most informative thing about a storage tank, and the least often looked at — because once it's gone, corrosion moves to the steel and the countdown to a leaking shell has started.
Storage tanks typically give eight to twelve years, longer with maintained anodes and softer water.
Individually, none of these condemns a unit. Together, they're a forecast.
Sound, part-consumed, or gone. The evidence for how much life the vessel has left.
And whether the deposit had hardened.
Rust staining, damp marks, corrosion at connections.
Against the setting.
And what system pressure is doing.
Not a precise number, because nobody can give one, but a straight answer to "should I be budgeting for this in the next year or the next five?"
Electric: the breaker, then the reset button on the upper thermostat.
Gas: whether the pilot is lit and whether other gas appliances work.
And if only one tap has no hot water, it almost certainly isn't the heater.
Planned
Chosen, compared, bookedYou choose the type and size, compare prices, decide whether tankless is worth considering, and book it for a convenient day at an ordinary rate. Possibly during a quiet period when installers aren't stretched.
Forced
Today, whatever's availableThe tank has leaked. There's water on the floor, no hot water in the house, and a decision to make today. You take what's available, at whatever rate applies, with whatever installation compromises the urgency imposes.
A tank that fails in a loft, an airing cupboard, or above a finished floor takes flooring, ceilings, and stored belongings with it. Which is why a drip tray and a leak alarm are worth fitting on any unit past the middle of its life.
The difference isn't just money. It's whether you got to make a considered choice about a piece of equipment you'll live with for a decade.
Which is the whole argument for being told the anode is gone in year eight rather than discovering the tank has in year eleven.
Most faults are, and on a unit with life left they're parts and an hour.
Common, inexpensive, fast.
Consumable parts — replacing one is routine, not evidence the unit is finished.
The commonest gas fault and one of the cheapest parts.
Component-level work.
The valve doing its job, or the valve failing. Never capped.
Water on a heater frequently comes from the plumbing rather than the vessel.
Hot and cold mixing inside the tank. Frequently misdiagnosed as a dying tank.
Flushing addresses it — and doing so before it hardens is the difference between maintenance and permanent capacity loss.
The highest-value replacement there is, because a fresh anode extends the life of the tank itself.
A leak from the body of the tank. Not a fitting, not a valve — the shell itself.
Storage tanks corrode from the inside. A glass lining protects the steel, and a sacrificial anode corrodes preferentially to protect it. When the anode is spent and the lining is breached, the steel goes — silently, over years, from a surface nobody can inspect.
By the time water appears through the tank wall, the failure is complete. No repair. Welding, sealants, and patches on a pressure vessel that heats and cools daily are delays with a worse ending.
Water at the base comes from the relief valve, the supply connections, the drain valve, or condensation as often as from the shell. Four of those five are repairs.
And note that this is the one failure the warnings predict. Rusty water, a spent anode, and corrosion staining are all reporting the same process — years before it finishes.
Anode, sediment, corrosion at fittings, outlet temperature. The condition of the unit, not only the fault you called about.
Because it's the cheapest part in the unit and the clearest evidence of how long the most expensive part has left.
Not a precise number — nobody can give one — but a straight answer to whether you should be budgeting this year or in five.
So the next visit compares against the last, and the trend is visible rather than remembered.
Chosen calmly, at an ordinary rate, on a convenient day, without water on the floor.
Because where a tank sits decides how expensive its failure is.

Anode condition, sediment level, corrosion staining at fittings, capacity loss, and age give a reasonable forecast — but only if somebody looks at all of them and tells you, which is rarely what happens at a repair visit.
A sacrificial rod inside the tank that corrodes instead of the lining. It's designed to be consumed, and once it's gone, corrosion moves to the steel. It's the cheapest part in the unit and the clearest evidence of how long the most expensive part has left.
An early corrosion signal, and worth acting on. If only the hot water is discoloured, the heater is the source — either corrosion inside the tank or a spent anode. This is exactly the kind of warning that gets noticed and not explained.
Sediment on the tank floor with water boiling underneath it. Not an emergency, but that layer is insulating steel from the water meant to cool it — so it's a symptom and an accelerator. Flushing addresses it, before the deposit hardens.
Sediment occupying tank volume, a failed dip tube, or a dead lower element. All three are repairs — but gradual capacity loss is also one of the readings that tells you where the unit is in its life.
Storage tanks typically give eight to twelve years, longer where the anode has been maintained and the water isn't hard. Tankless runs considerably longer. Age alone doesn't condemn a heater, but past eight years it's worth knowing the condition rather than assuming.
Because you choose the unit, compare prices, pick a convenient day, and pay an ordinary rate. A forced replacement means taking what's available, today, at whatever rate applies — frequently with water damage on top.
Only if it's leaking from the body of the tank. Water at the base comes from the relief valve, the connections, the drain valve, or condensation as often as from the shell — and four of those five are repairs.
On any unit above a finished floor or in a loft, and particularly once it's past the middle of its life. Where a tank sits decides how expensive its failure is, and a tray plus a leak alarm is inexpensive insurance.
Never. That valve is the safety device on a pressure vessel. The discharge means excess pressure, excess temperature, or a failed valve — all addressable.
On electric: the breaker, then the reset button on the upper thermostat. On gas: whether the pilot is lit and whether other gas appliances work. Both free, and both occasionally solve it.
Yes — falling output, longer waits, and error codes are the equivalent, and they're almost always scale-related. Descaling on schedule is what prevents the sequence.
Tanks don't fail suddenly. They corrode on a schedule and announce it for years — rusty water at first draw, rumbling on the floor, capacity slipping, an anode nobody looked at. The failure feels sudden only because each warning was answered separately and never added up.
TrueFlow Plumbing checks the anode at every visit, reports the sediment and the corrosion as well as the fault you called about, gives you an honest estimate of remaining life, and writes it down so next time there's something to compare against.
