If a pilot light on a gas water heater fails to ignite, it could be due to a defective thermocouple, clogged pilot tube, insufficient gas flow, or a malfunctioning gas control valve. It is important to have a professional technician diagnose and fix the issue to ensure safe and reliable operation of the water heater.

Why does water heater pilot light go out when gas is turned on?

If the pilot light goes out when the gas is turned on, it could be due to a dirty or faulty thermocouple, a clogged pilot tube, or a problem with the gas supply. It's important to have a professional inspect and repair the water heater to ensure it is functioning safely and effectively.


Hot water in bath not working?

Check if the hot water valve is fully open. If it is partially closed, this may be restricting the flow of hot water. Additionally, it could be an issue with the water heater or a problem with the temperature setting on the water heater itself. It may also be worth checking for any leaks or blockages in the pipes that could be affecting the hot water flow. If the issue persists, it may be best to contact a plumber for further assistance.


How long is the electric water heater can boil a glass of water?

An electric water heater typically takes around 5-10 minutes to boil a glass of water, depending on the volume of water and the power of the heater.


Can the hot water heater leak to the main line you have no sign of a leak except the sound in the wall?

Yes, it is possible for a hot water heater to leak into the main water line. If you hear a sound in the wall that could indicate a leak, it's important to investigate further and possibly seek professional help to prevent further damage. Water leaks can cause structural damage and mold growth if left untreated.


What causes a hot water heater to stop heating the water?

A hot water heater may stop heating water due to a variety of reasons including a broken heating element, a malfunctioning thermostat, sediment buildup in the tank, a faulty pilot light or gas valve (for gas water heaters), or a tripped circuit breaker or blown fuse (for electric water heaters). Regular maintenance and troubleshooting can help identify and resolve the issue.

Water pool heater trouble shooting?

A number of problems can cause a swimming pool heater not to work. The most common I have found is lack of water flow. A heater needs a certain amount of water flowing through it to work correctly. The next most common problem is due to the pilot not lighting or remaining lit. This is usually due to the pilot generator not working. When you light a pilot light and have to hold it for a length of time before releasing the button you are allowing the pilot generator to heat up and then stay open to keep the pilot lit. Usually you need a licensed person to do work with changing items on a gas unit. The thermostat can be a problem for any water heater. Most of the heaters I have worked on were gas. If you have an electric heater waterflow still needs to be checked and the electrical connections can become corroded in the presence of chemically treated pool water.


Does the water heater still fill with water when the pilot light is off?

When the pilot light is off does the water heater still fill up?

What causes the gas water heater pilot light to go out?
