What to Do When Your Richmond Water Heater Starts to Fail

What a Richmond water heater does on its way out depends a great deal on how it is fuelled, and around here the fuel is settled by a natural gas utility the city itself owns. That sounds like administrative trivia until the hot water starts behaving strangely, at which point it decides which symptoms you should be watching for and what a technician will look at first.

Most tanks give warning. Very few give it loudly, and the ones that flood a room have usually been dropping hints for months.

Key Takeaways: What the Tank Is Telling You, and How Long You Have

• Fading is a warning, going out is a failure: a tank that still gets hot but runs short earlier than it used to is asking for an appointment, not an emergency.
• The fuel narrows the fault list before anybody touches the unit, so know which one you have before you call.
• Rust in the hot water and nowhere else points at the inside of the tank rather than at the supply coming into the house.
• Damp underneath is never nothing: find out where it starts before deciding it is condensation or a fitting.
• Where the unit stands decides how much damage it can do, and a crawl space gives you no warning at all until a floor above it feels cold and soft.
• Roto-Rooter is fully licensed and insured, has worked on water heaters since 1935, and takes calls 24/7, 365 days a year.

Rust, Rumble and a Weeping Relief Valve: Reading a Tank on Its Way Out

The signs below are worth acting on in roughly this order. None of them is proof on its own, and two together usually settle the question.

• Discoloured hot water: brown or rust-tinted at the hot taps while the cold runs clear says the lining and the anode are losing the argument.
• Rumbling or popping: sediment lying over the burner or the lower element, boiling the water trapped underneath it, which wastes energy and stresses the steel.
• A relief valve that weeps: either the valve itself has failed or the system pressure is doing something it should not, and both need looking at.
• Hot water running short earlier than it used to: a gradual loss of usable capacity as the bottom of the tank fills with sediment.
• Rust, staining or damp at the base: trace where the water starts before assuming, because a fitting overhead can drip down the shell and imitate a failing tank.

Richmond Owns Its Gas Utility, and Its Mains Do Not Stop at the City Line

Richmond Gas Works is not an outside company. It is a division of the city's Department of Public Utilities, a municipal gas system and one of the oldest still operating anywhere in the country, and its mains run out past the city boundary into Henrico and into parts of Chesterfield and Hanover. Which means the fuel under a house in this market follows the pipe in the street, not the jurisdiction on the deed. Two houses of similar age and layout a few miles apart can be gas and electric, and plenty of county households get a gas bill from a city they do not live in.

That matters when the hot water misbehaves, because the two kinds of tank fail in different shapes. An electric unit has two elements and two thermostats and tends to fail in halves: lose the lower one and you get a modest amount of hot water that disappears quickly, lose the upper one and you get none at all. A gas unit is more likely to go from working to dead in a single step, at the pilot assembly, the thermocouple or the gas control valve, and it has a flue to consider that an electric tank does not.

Recovery differs too. A gas burner puts heat back into a drained tank considerably faster than a pair of electric elements will, so a household that has changed fuel without changing capacity notices it on the second and third shower. And it shapes the replacement conversation: moving from one fuel to the other is not a swap, because it turns on a main being in the street and a meter being at the house, and that is a question for the utility before it is a question for anybody else.

How Much Warning You Get Depends on the Room the Tank Is In

In the older brick rowhouse stock the unit usually stands in a cellar or basement with a hard floor and a drain in it, which is the kindest place a tank can pick to fail. Out in the county ranches it tends to be in a vented crawl space or a utility room off the carport, where nothing is visible from inside the house and the first sign is a cold, soft patch of floor overhead. Newer two-storey houses put it in a closet on an upper level, where a pan and its drain line are the only things standing between a split tank and the ceiling below.

Two things follow from that. Check that the pan drain actually discharges somewhere you can see rather than dying inside a wall cavity, because a pan that cannot empty is decoration. And in an unconditioned space through a humid Richmond summer, find out where a damp patch begins before calling it a leak, since bare copper and cold steel sweat here for months at a stretch.

If the Tank Is Already Leaking, Do This Tonight

1. Take the energy off it properly. For an electric unit that means the breaker in the panel, not the thermostat dial. For a gas unit, turn the control on the front to off. Leaving either one live over a dropping water level is how a bad night becomes a worse one.
2. Shut the cold feed where it enters the unit. There is normally a valve sitting on that pipe within arm's reach of the top of the heater. Should it refuse to move, close the main to the whole house instead and deal with the seized valve another day.
3. Open a hot tap somewhere upstairs. It breaks the vacuum and lets the tank stop pushing water out under pressure.
4. Get everything off the floor around it. In an older cellar the floor drain may take it, in a crawl space nothing will, and in a closet on an upper floor the ceiling below is what pays.
5. Leave the drain valve alone on a rusted tank. Those plastic spigots break off in the hand, and a drain valve that will not reseat turns a slow weep into an open outlet.

Frequently Asked Questions About a Water Heater That Is Starting to Fail

How do I find out whether my street has a gas main?

Ask the gas utility with the address in hand, and they will tell you what is in the street and whether a meter can be set. Neighbours are a decent early indicator, since mains were laid street by street rather than neighbourhood by neighbourhood.

The house is in the county but the gas bill comes from the city. Is that a mistake?

No, that is normal here. The city-run gas system serves customers well beyond its own boundary, so an address in Henrico or Chesterfield can quite properly be billed by the city for gas while everything else comes from the county.

Would a tankless unit make sense in a cellar with a masonry chimney?

It can, and the venting is the question that decides it, because a tankless appliance will not use the existing flue and needs its own sealed vent run to outside air. Gas supply sizing matters as well. Both get checked on site before anything is recommended.

Does swapping from electric to gas cost more than a like-for-like replacement?

It is a larger job, since it involves the utility, a meter, a gas line to the appliance and a vent, none of which a straight replacement needs. Cost varies by what is already at the house, and Roto-Rooter provides on-site estimates before any work begins.

Is a permit and inspection part of a straight tank swap?

Yes, replacements are permitted work here, and the company doing the job pulls it. Current requirements also add items an older installation may not have, such as an expansion tank on a closed system and a pan with a drain where the unit sits above living space.

A tank that is still making hot water is a job you get to plan, which is a much better position than the one you are in at two in the morning with a wet floor. Roto-Rooter works across the city and the surrounding counties and you can schedule online whenever suits. If the tank has already let go, Richmond emergency plumbers is the faster door. Otherwise put it in the diary for a weekday, and the Richmond plumbers page has the branch details.
