In an older property, the water heater is frequently the newest thing in the plumbing — and that creates problems nobody warns you about.
A modern unit installed into a hundred-year-old system inherits everything around it. Galvanised supply pipe delivering rust into a new tank. No expansion vessel on a system that now has one fitted somewhere. A relief valve discharging because incoming pressure was never checked. A gas supply sized decades ago for a much smaller appliance.
And when it fails early, the heater gets blamed.
Then there's the reverse problem: the genuinely old heater, sitting in a cupboard with pipework nobody can identify, connections that haven't been disturbed in thirty years, and a replacement that turns out to need considerably more than a straight swap.
Which is why "how old is the house" matters as much as "how old is the heater."
The unit is only ever as good as what's feeding it.

Rust and scale from decades-old steel arrives in a new tank, accelerating sediment and shortening its life. The heater is fine; what's feeding it isn't.
Older properties frequently have no pressure-reducing valve — and a relief valve discharging repeatedly is usually reporting system pressure rather than a faulty valve.
On a closed system, water expanding when heated has nowhere to go — which shows up as a discharging relief valve and stressed joints throughout.
Common where a heater has been upgraded but the line hasn't — and it limits output in a way that looks like an undersized unit.
Copper onto galvanised steel corrodes at the junction unless the correct dielectric fitting separates them. A very common finding at older heater installations. And sediment arrives faster than expected, because the supply system is shedding it.
Old threaded joints, seized unions, and corroded fittings sometimes have to be cut back to sound material. Worth knowing before a "straight swap" is quoted.
Cupboards built around units, doorways too narrow, and lofts reached by ladder. A tank that went in before a wall did.
Galvanised, copper, lead, or a mixture.
Which may need bringing up to current requirements.
Frequently no valve on the cold feed, so any work means the whole property's water off.
Gas line size, meter capacity, or electrical service.
None of this is a reason to avoid the work. It's a reason to survey before quoting — rather than discovering it halfway through.
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.
The heater is the source — corrosion inside the tank, or a spent anode.
The supply pipework is the source — and in an older property that usually means galvanised steel corroding from the inside.
Replacing a water heater because of rusty water, when the rust is coming from the supply pipe, replaces the wrong thing — and the new tank starts collecting the same corrosion product from day one.
And it works the other way too. A tank that's shedding rust into an old system is at the end of its life, and no amount of pipe work fixes it.

Routine replacement.
Along with igniter and gas control faults.
The valve, or the pressure it's protecting against — and in an older property, check the pressure before replacing the valve.
In older installations, seized fittings sometimes do.
Flushing addresses it — and in a property with galvanised supply, there's more to flush. Dip tube failure sits here too.
The cheapest part in the unit, deciding how long the most expensive part lasts.
A leak from the body of the tank. Not a fitting, not a valve — the shell itself. By the time water appears through the tank wall, the failure is complete. No repair.
Water at the base comes from the relief valve, the connections, the drain valve, or condensation as often as from the shell. Four of those five are repairs — and in an old installation with corroded fittings, connection leaks are common.
The replacement in an older property needs surveying rather than assuming. Access, pipework material, gas or electrical capacity, and isolation all need checking before a date is set.
A new tank in an old system inherits everything around it — and early failures are frequently the supply, not the appliance.
Because replacing a heater over rusty water that's coming from galvanised supply pipe replaces the wrong thing.
A valve discharging repeatedly is usually doing its job correctly.
Access, pipework material, gas and electrical capacity, and isolation — none of it safe to assume.
Copper onto galvanised steel corrodes at the junction without a dielectric fitting, and it's a very common finding at older installations.

Galvanised supply pipe shedding rust into a new tank, uncontrolled incoming pressure, no expansion provision, and a gas line sized decades ago all shorten a modern unit's life — and the heater gets blamed.
Not necessarily. Run the cold as well and compare. If only the hot is discoloured, the heater is the source. If the cold is discoloured too, particularly at first draw, the supply pipework is — usually galvanised steel corroding from the inside. Replacing the heater in that case replaces the wrong thing.
Then it probably isn't the valve. It's frequently doing its job correctly, protecting the vessel from uncontrolled incoming pressure or a closed system with no expansion provision — both common in older properties, and both correctable.
Because dissimilar metals in contact with water corrode at the junction, from the inside, unless a dielectric fitting separates them. It's a very common finding at older water heater installations and a genuine cause of early failure.
Frequently not, and it's worth surveying rather than assuming. Connections that haven't been disturbed in thirty years may need cutting back. Access may have been built around the unit. Gas line size, electrical capacity, and isolation all need checking.
In a property with galvanised supply pipe, expect more of it — the supply system is shedding corrosion product into the tank. Flushing addresses it, but more frequently than in a modern installation.
A sacrificial rod inside the tank that corrodes instead of the tank 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 it decides how long the most expensive part survives.
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 are free and occasionally solve it.
Only if it's leaking from the body of the tank. Water at the base comes from the relief valve, connections, drain valve, or condensation as often — and in an old installation with corroded fittings, connection leaks are particularly common.
Worth checking whether you need one. Older properties frequently have no pressure control at all, and uncontrolled incoming pressure stresses the tank, the relief valve, and every joint in the building continuously.
Common in older installations, and it means any work requires the whole property's water off. Fitting one is inexpensive alongside work that's already happening.
Eight to twelve years for a storage tank, longer with a maintained anode — but in an older system with uncontrolled pressure and corroding supply pipework, expect the lower end unless the surrounding issues are addressed.
A water heater is only ever as good as what feeds it, and in an older property that's frequently the problem — galvanised pipe shedding rust into a new tank, pressure nobody has measured, no expansion provision, and a gas line sized for something smaller. The unit fails early and takes the blame.
American Plumbing Experts assesses the system as well as the appliance, establishes whether rust is coming from the tank or the pipe, checks pressure before condemning a relief valve, and surveys an old installation before quoting a replacement.
