Those who are looking for an answer to the question «Koso seismic gas shutoff valves?» often ask the following questions:
👉 What do you need to know about gas shutoff valves?
- Note that all piping in the house (everything on the house side of the outdoor gas meter) is the homeowner's responsibility. All gas appliances have local shutoff valves. These typically have lever-type handles that you can turn by hand to control gas flow to an individual appliance.
- Are furnace gas valves universal?
- Are gas control valves universal?
- Are honeywell gas valves universal?
👉 Where is my gas shutoff?
- Locate the main gas shutoff valve. Your main gas shutoff valve is normally located near your gas meter. The most common places are on the side or front of a building, a cabinet located inside a building or a cabinet meter outside a building.
👉 Are gas valves interchangeable?
The companies that make the gas valves usually put a different part number on the valves for each of these heater companies. This makes finding the right replacement valve tricky. Although you can go back to the manufacturer to buy replacement parts using the part number of the heater, you usually wind up paying a lot more for the valve and will have a hard time getting the valve shipped quickly.

Where is the gas shutoff valve on a house?- Houses with natural gas have a main shutoff valve ( Fig. A) located just before the gas meter. This valve, often called the street-side valve, is normally a rectangular nub ( Photo 1 ). When the long side of the nub or handle is parallel to the incoming gas line, it’s open and the gas is flowing.
- The Watts 210 is a self-contained device that includes a manual reset button, a trip latch assembly and a thermostat. As we stated earlier, the valve is installed where the T&P valve would normally be installed on the water heater.
- If the requirement for a shutoff within 6ft of the appliance would be satisfied by a valve right under the floor in the basement--which would be less than 6ft linear, but take 25 ft walk downstairs to get to-- I am inclined to take that route.
- Ball valves are durable and typically work to achieve perfect shutoff, even after years of use. For this reason, ball valves are the preferred choice for shutoff applications. Hydrovalve gas ball valves have female threaded (IPS) connections and are available in 1/2", 3/4", and 1" sizes.
Natural and propane water heater gas valves are not interchangeable, so, be sure to order a valve for your type of gas.
