How A Water Heater Works

Most problems with water heaters are begin with noises or by water that's too hot or not hot enough. You can often fix the problem yourself. An exception is a water leak, which may require professional service or a tank replacement. Gas leaks call for immediate help from a plumber.

When someone turns on a hot water faucet, heated water is drawn from the top of the tank and is replaced by cold water that is carried to the bottom through the dip tube. When the water temperature drops, a thermostat activates the heat source (a burner in a gas model -- two heating elements is an electric.) A gas heater has a flue running up the center and out the top to vent deadly gasses. An electric water heater needs no venting. In both, an anti-corrosion anode attracts corrosion that would otherwise attack the tank's walls.

Maintenance For Good, Safe Service

Water Heater Safety Tip

If the steam or boiling water comes out of the valve or the hot water faucets, shut the heater off at once. If you ever hear a rumbling sound, assume the heater is overheating and turn it off.

Water Temperature

If the temperature is a hitch on a gas heater, check whether the temperature control is on. Set the control correctly (normally 160).Set it a little lower if there's no dishwasher. If you suspect a faulty control, test it by opening a hot water faucet for 3 minutes. If the heater doesn't turn on, reset the control to a lower temperature and test again. If it still fails, have it replaced.

Draining and Flushing the Tank

  1. Turn off the gas or electricity.
  2. Close the cold water valve.
  3. Attach a hose to the drain valve to route water into a drain or outdoors.
  4. Open up the drain valve and open one hot water faucet somewhere in the house to let in air.
  5. When all the water has drained, turn the cold water valve on and off until the water from the drain looks clear.
  6. Close the drain valve and the hot water faucet, open the cold water valve and restore power.

Troubleshooting Gas Water Heaters

See the instructions on the tank to learn how to light the pilot light. A gas heater has a thermocouple for safety. This is thermoelectric device that impinges on the pilot flame and shuts off the gas if the pilot light goes out. The gas flame should be blue. If it's orange, adjust the shutter; if it's still orange, call for service.

You should inspect the flue assembly twice a year to be sure it's properly aligned and all its joints are sealed. Then check the flue by placing your hand near the draft diverter (with the burner on); air flowing out indicates an obstruction that should be removed. Every year or two, shut off the gas, remove the access panel, and clean the burner ports, using stiff wire or a needle. If you ever smell gas, get out of the house immediately and call the gas company.

* Note Premature failure on water heaters and plumbing fixtures is most often due to excessive water pressure (above 80 p.s.i.). Your plumber can test your water pressure to see if it is within safe limits, and make suggestions to reduce the pressure if it’s necessary.

There is No Hot Water

Check for:
  • Unlit pilot light.
  • Pilot light won't keep burning.
  • Clogged burner
  • Defective thermocouple.
  • The gas is not coming out.
Remedies:
  • Carefully relight the pilot.
  • Make sure the gas controls are completely turned on. Then check the thermocouple and be sure it is firmly connected to the gas control unit and positioned near the pilot flame.
  • Call a qualified plumbing contractor.
  • Replace the thermocouple.
  • Inspect or test gas control valve

There isn't Enough Hot Water

Check for:
  • Incorrectly set thermostat.
  • Defective thermostat.
  • Too small of a water tank
  • Clogged burner.
  • Sediment has formed in the tank.
  • Leaking hot water faucets.
Remedies:
  • Turn the thermostat higher.
  • Call a qualified plumbing contractor.
  • Install a larger water tank.
  • Turn off the gas and drain the tank.
  • Repair or replace the faucets.

The Water Heater is Very Noisy

Check for:
  • Scale and sediments in the tank.
Remedies:
  • Turn off the gas and drain the tank.

The Water is Too Hot

Check for:
  • Wrong setting on thermostat.
  • Defective thermostat.
  • Blocked exhaust vent.
Remedies:
  • Reset the thermostat.
  • Call a qualified plumbing contractor.
  • Check the vent and clear it.

Water is Leaking from the Heater

Check for:
  • Leak in the draincock.
  • Leaking safety valve.
  • Hole in the tank.
  • Leak in the plumbing connection.
Remedies:
  • Close it tightly or replace it.
  • Check the water temperature. If it's too hot, the thermostat may be broken. If the safety valve is defective, replace it.
  • Buy a new water heater.
  • Call a plumber.

* Note premature wear & tear on water heaters (and plumbing fixtures) is most often attributed to excessive water pressure (above 80 p.s.i.). See information related to pressure reducing valves.

Troubleshooting Electric Water Heaters

When an electric heater has problems, suspect the heating elements, their thermostats, and the high-temperature cutoff. The two heating elements (upper and lower), immersed in water, are controlled by thermostats which, along with the high-temperature cutoff, are concealed behind a panel on the side (insulation must be cut away for access after removing the panel). If the high-temperature cutoff has tripped due to water that's too hot, the solution may be as easy as pushing the reset button. High voltage and inaccessibility warrant a service call to adjust the thermostats, reset the high-temperature cutoff, or to replace any of these components of the heating elements themselves.

No Hot Water

Check for:
  • The heater has no power.
  • The safety thermostat has quit working.
  • Defective heating thermostat.
  • Defective heating elements.
  • Accumulation of rust, scale, or sediment in the tank or pipes.
Remedies:
  • Check the fuse box/ circuit breaker.
  • If the heater repeatedly blows fuses call your plumber.
  • Push the reset button.
  • Test the heating thermostats and elements.
  • Test the thermostats and replace if necessary.
  • Test the elements and replace if necessary.
  • Drain and flush the tank and pipes.

Hot Water Supply is Too Low

Check for:
  • Thermostat is set wrong.
  • The tank is too small.
  • Heat is getting loose in the pipes.
  • Defective heating element.
  • Leaking hot water faucets.
Remedies:
  • Turn the thermostat to a higher temperature.
  • Install a larger heater.
  • Move the heater nearer to the point of use if possible.
  • Insulate the hot water pipes.
  • Test the element then replace it.
  • Repair or replace the faucets.

Water Temperature is Too High

Check for:
  • Thermostat is on the wrong setting.
  • Inadequate insulation around the thermostats.
Remedies:
  • Turn up the thermostat.
  • Add insulation around the thermostats.
  • Test the thermostat and replace if necessary.

Water Leak

Check for:
  • Defective gasket or seal on the element.
  • Defective safety valve.
  • The tank is rusted through.
  • Leaking plumbing connections.
Remedies:
  • Check and replace gasket or seal.
  • Check and replace the safety valve.
  • Consider replacing water heater.
  • Call a qualified plumbing contractor.

Water Heater Becomes Unusually Noisy

Check for:
  • Accumulation of rust, scale or sediment in the tank.
  • Scale has formed on the elements.
Remedies:
  • Drain the tank and flush it out.
  • Remove the elements, soak with vinegar and then scrape off the scale.

Hot Water Pipe is Rusty or Discolored

Check for:
  • Accumulation of rust or sediment in the tank.
  • Scale has formed on the elements.
  • Corroded water pipe.
Remedies:
  • Drain the tank.
  • Remove the elements, soak them in vinegar and then scrape off the scale.
  • Have a plumber inspect for necessary repairs.

Troubleshooting Toilet Problems

How your toilet works:

There are assemblies under the lid of a toilet tank; a ball cock assembly, which regulates the filling of the tank, and a flush valve assembly, which controls the flow of water from the tank to the bowl. When you press the flush handle, the trip lever raises the lift wires (or chain) connected to the tank stopper. As the stopper goes up, water rushes through the valve seat into the bowl via the flush passages. The water in the bowl yields to gravity and is siphoned out the trap.

Once the tank empties, the stopper drops into the flush valve seat. The float ball trips the ball cock assembly to let a new supply of water into the tank through the tank fill tube. As the tank water level rises, the float ball rises until it gets high enough to shut off the flow of water. If the water fails to shut off, the overflow tube carries water down into the bowl to prevent an overflow.

* Note, San Francisco water is known to contain 'Cloramine' which is a chemical known to wear rubber parts rapidly.

Noisy Toilet

Check for:
  • Restricted water flow.
  • Defective ball cock assembly.
Remedies:
  • Adjust the shutoff valve first.
  • Oil the trip lever or replace the ball cock washers.
  • Replace the entire ball cock assembly.
  • CAUTION: First turn off the water at the fixture shutoff valve. Then flush the toilet to empty the tank and sponge out any remaining water.

Running Toilet

Check for:
  • Float arm not rising high enough.
  • Water-filled float ball.
  • Tank stopper not seating properly.
  • Corroded flush valve seal.
  • Cracked overflow tube.
  • Ball cock valve doesn't shut off.
Remedies:
  • Bend float arm down or away from tank wall.
  • Replace ball.
  • Adjust stopper guide rod and lift wires or chain. Replace defective stopper.
  • Scour valve seat or replace.
  • Replace tube or install new flush valve assembly.
  • Oil trip lever, replace faulty washers, or install new ball cock assembly.

Clogged Toilet

Check for:
  • Blockage in drain.
Remedies:
  • Remove blockage with plunger or closet auger.

Inadequate Flush

Check for:
  • Faulty linkage between handle and trip lever.
  • Tank stopper closes before tank empties.
  • Leak between tank and bowl.
  • Clogged flush passages.
Remedies:
  • Tighten setscrew on handle linkage or replace handle.
  • Adjust stopper guide rod and lift wires or chain.
  • Tighten tank bolts or couplings or replace gasket.
  • Clear obstructions from passages with wire.

Leaking Toilet

Sweating tank

This problem occurs most often in the summer when cold water in the tank cools the porcelain, and warm, moist air encourages mildew, loosens floor tiles, and rots sub-flooring. An easy solution is to insulate the inside of the tank by draining it and then gluing a liner made of foam rubber pads to the inside walls. A more costly remedy, and one that's usually a job for a professional, is to install a tempering valve that mixes hot water with the cold water entering the tank.

Check for:
  • Condensation.
Remedies:
  • Install tank insulation or a tempering valve.

Drains

Sink Drains
Clearing Drains with a Plunger
Using Chemical Drain Cleaners

Sink Drains

A stopped sink drain isn't just an inconvenience; it can sometimes be an emergency. It's always best to prevent clogs before they happen. Be alert to the warning signs of a sluggish drain. It's easier to open a drain that's slowing down than one that's stopped completely.

Clearing Drains with a Plunger

The plunger is a good drain-clearing tool, but it often fails to work because it's incorrectly used. Don't make the typical mistake of pumping up and down two or three times, expecting the water to whoosh down the drain. Though no great expertise is needed to use this simple tool, here are a few tips to guide you:

Using Chemical Drain Cleaners

Though routine use of chemical drain cleaners to prevent clogs may eventually damage your pipes, these cleaners can be helpful in opening clogged drains. If water is draining somewhat, but plunging has failed to open the drain completely, you may want to try using a drain cleaner. Whenever you use chemicals, do so with caution and in a well-ventilated room. Be sure to take these precautions:

Safety Tip:


Clogged Drains

Before trying any drain-clearing methods on a plugged drain, check that the tub's pop-up stopper is opening fully and is free of hair and debris. If the stopper isn't the problem, then the drainpipe is probably clogged. First, try a plunger or chemical drain cleaner.

If these fail to do the job, you'll have to clear the trap with a snake.


Clogged Showers

Though it may difficult to unclog a shower drain with a plunger, it's worth a try. If that doesn't work, maneuver a snake down the drain opening into the trap. As a last resort, you can use a garden hose.

CAUTION: Never leave a hose in any drain: a sudden drop in water pressure could siphon sewage back into the fresh water supply.


Preventing Kitchen Drain Clogs

No plumbing problem is more common or more frustrating than a clogged drain.

Drains can usually be cleared easily and inexpensively, but taking some simple precautions will help you avoid stop-ups. Proper disposal of kitchen waste will keep sink drain clogs to a minimum.

Sink Faucets

The first step in fixing a leaking or sluggish faucet is identifying which of the two basic types of faucets you're dealing with.

Professional Tips

Leaking Compression Faucets

If your faucet has separate hot and cold water handles, it's probably a compression faucet (also called a stem or washer faucet). In this faucet, a rubber seat washer is secured to the stem, which has very coarse threads on the outside. When you turn the handle to shut off the faucet, the stem is screwed down, compressing the washer against the valve seat in the faucet body. The stem is secured by a packing nut, which compresses the packing (twine, a washer, or an O-ring) and prevents water from leaking around the stem.

Professional Tip

Before doing any work, turn off the water at the fixture shutoff valves or at the main shutoff valve. Open the faucet to drain the pipes.

Taking the Faucet Apart

Replacing the Packing and Washer

Working On the Valve Seat

Cleaning Your Faucet Aerator

If the flow from your faucet is sluggish, the trouble may be in the faucet aerator. This device, at the tip of most faucet spouts, mixes air and water for a smooth flow. But minerals or dirt particles in the water often build up on the screen and disc, blocking the flow. If mineral deposits are to blame or if aerator parts are damaged, it's best to replace the aerator. If dirt is the problem, follow these steps:

Leaking Valve Faucets

A valve faucet has a valve assembly on each side (one for hot water, one for cold) through which water flows up and out the spout. Moving the handle from side to side controls the mix, moving forward and backward controls the flow.

Leaking Ball Faucets

In a ball faucet, water flows when openings in the rotating all align with hot and cold water inlets in the faucet body.

Leaking Cartridge Faucets

A cartridge faucet has a series of holes in the stem-and-cartridge assembly that align to control the mix and flow of water. Usually, leaks occur because of worn O-rings or a faulty cartridge.

Tub Faucets

Like sink faucets, tub faucets can be compression style or washerless. To take apart any style tub faucet, pry off the cap, unscrew the handle, and remove the escutcheon. In a compression faucet, you'll see the stem and packing nut. You may need to use a deep-socket wrench to grip and loosen a recessed packing nut. To repair a washerless tub faucet, remove the stop tube and draw out the retainer clip to get at the cartridge.


Shower Heads


Sink Sprays and Diverters

A kitchen sink spray has a spray head attached to a hose, which is connected to a diverter valve in the faucet body. When you squeeze the spray head handle, the diverter valve reroutes water from the faucet to the spray head hose.


Leaking Pipes

A higher than normal water bill might be your first indication of a leaking pipe. Or you might hear the sound of running water even when all your fixtures are turned off. When you suspect a leak, check the fixtures first to make sure all the faucets are tightly closed. Then go to the water meter, if you have one. If the dial is moving, you're losing water somewhere in the system.

Locating the Leak

Try these tips to locate a leak.

Fixing the Leak

If the leak is major, turn off the water immediately, either at the fixture shutoff valve or the main shutoff valve. You'll probably have to replace the leaky section of pipe. If your experience working with pipes is limited, you'll probably want to call in a plumber to do the job. If the leak is small, the ultimate solution is to replace the pipe, but there are temporary solutions until you have time for the replacement job. These methods work for small leaks only.


Pipes Making Noise?

Noisy Pipes
Banging
Squeaking
Water Hammer

Noisy Pipes

Pipe noises range from loud hammering sounds to high-pitched squeaks. The causes may be loose pipes, water logged air chambers, or water pressure that's too high. Anchoring exposed pipes is a simple solution; other remedies such as anchoring pipes concealed inside walls, floors or ceilings, may call for a professional.

Banging

Pipes are usually anchored with pipe straps every 6 to 8 feet for horizontal runs, 8 to 10 feet for vertical.

Squeaking

Only hot water pipes squeak. As the pipe expands, it moves in its strap, and friction causes the squeak.

Water Hammer

This noise occurs when you turn off the water at a faucet or an appliance quickly. The water flowing through the pipes slams to a stop, causing a hammering noise.

Check for:
  • Loose Pipes
Remedies:
  • Anchor the pipes.
Check for:
  • Faulty air chambers. These lengths of pipe, installed behind fixtures and appliances, hold air that cushions the shock when flowing water is shut off. They can get filled with water and lose their effectiveness.
Remedies:
  • To restore air to the chambers, turn off the water at the main shutoff valve. Open all the faucets to drain the system. Close the faucets and turn the water on again. The air chambers should fill with air.
Check for:
  • Water pressure that's above 80 psi (pounds per square inch).
Remedies:
  • To lower the pressure, install a pressure-reducing valve (you can call in a plumber to do the work if this is a job you don't want to do yourself).
