The Smart Valve is a

patented, USA made device

that is installed on the user side of your incoming water line that creates a steady back pressure through your water meter. … 99% of meters on the market do not recognize the difference between water and air, so they count BOTH as volume!

What makes a smart valve smart?

The Smart Valve system uses

a 24 VAC powered hot surface pilot gas igniter to ignite the pilot gas

. The main gas is ignited in both instances by a pilot gas burner. The Smart Valve system is self-contained, thus eliminating the need for a separately mounted ignition source, usually in the or boiler vestibule.

How does an automatic gas valve work?

The automatic valve is connected to the thermostat control circuit. When the thermostat contacts close to call for heat, a solenoid type valve

permits gas to flow to the main burner

. The high limit switch shuts off power to the solenoid if the limit senses too high a temperature.

How do I know if my gas valve is bad?

If you notice

strange noises

from your furnace, airflow distribution is weak, or it starts to cycle between on and off settings continuously, you likely have problems that don't involve the gas valve. A service visit to troubleshoot the problem is needed.

How do you check voltage on a gas valve?

  1. Turn off the furnace at the wall control. …
  2. Take out the bolts in the service panel on the side of the furnace using a nut driver. …
  3. Pull the wires off the gas valve terminals. …
  4. Turn the test control on the multimeter to “mV,” which stands for millivolt.

Can a gas valve be repaired?


The gas valve cannot be repaired in the field

. Only the gas valve manufacturer or someone certified by the manufacturer of the gas valve can make repairs. Then re-certifying the safety of the gas valve.

What causes a gas valve to go bad?

The

valve itself may have simply worn out or may be damaged due to basement seepage or submersion

. Alternately, one of the electronic gas ignition components or a glitch in the safety circuit may be to blame. If your furnace has a standing pilot light, the thermocouple could be worn out.

Why do gas furnace efficiencies jump from 80% to 90 %?

Why do gas furnace efficiencies jump from 80% to 90%? Efficiencies

over 80% cause condensation

but the flue gas is still too hot for PVC vent pipe until the efficiency reaches 90%.

How much does it cost to replace a gas valve?

A furnace gas valve costs anywhere from

$200 to $600

to replace. This part allows or propane to flow to your unit. It's usually attached to the thermocouple for emergency cutoff when necessary.

How do you reset a gas valve?

Once the valve is turned off, do not turn it back on by yourself.

It must be turned on by a gas company technician

. The gas company will likely perform a pressure test on the system and relight all pilot lights in the house as part of turning the gas back on.

How do you test a gas valve solenoid?

The quickest way to test the solenoid valve is

to apply a charge directly to it

. There are two wires which cross directly above the valve as it lays in the timer that you will touch with a multimeter. This should send a charge onto the valve, and if it is functioning normally, it will open.

How do I reset my Honeywell gas valve?

Turn the water heater's

gas valve switch to the “OFF” position, wait for a few seconds and then flip the switch to the “ON” position

to reset the system. The water heater's gas valve is located near the bottom of the unit and connects to your home's natural gas line.

What does gas control valve failure mean?

Gas control valves do not fail often, but it can happen in rare instances. The thermocouple is a more likely culprit, and can be replaced without much expense. … Even though the limiter can be replaced, it probably indicates a

failure in the thermostat or

gas control valve as well.
