Why It’s Important to Flush Your Water Heater
Your plumbing equipment is generally low-maintenance and requires little attention to work properly for quite a long time. However, your water heater is perhaps the only piece of equipment that is very much the opposite. Every year, a water heater needs to be flushed to preserve it and ensure that it continues to function properly.
Why Flush Your Water Heater?
Flushing your water heater is important for a number of reasons, but most importantly it’s to get rid of things like dirt, minerals, and other sediment that may have built up in the bottom of your water heater tank. When water enters your home through your main water inlet, it’s not perfectly clean. In fact, it’s extremely common for your water to have concentrations of things like calcium and magnesium in them. While these substances aren’t bad for you (and actually have some health benefits), they can accumulate, solidify, and could even mix with dirt and other inclusions which are fairly common, becoming sediment that accumulates at the bottom of your water heater tank.
This sediment layer causes a few issues. First, it actually increases the chances of a leak springing out of the bottom of your tank. Second, it prevents your water heater from heating as effectively. Most gas-powered water heaters function with a burner located at the bottom of the tank which warms the water, causing it to rise, and heat more evenly. Sediment at the bottom acts as an insulator, preventing the heat from traveling as easily, and requiring your burner to stay on longer to heat the water. This burns more fuel and costs you more money while also being harder on your tank and causing it to wear out faster.
How to Flush Your Water Heater
Flushing your water heater is generally simple. All you need is a hose that can connect tightly to the flushing valve on the side of your tank, and a large bucket. First, shut off the gas or electrical connection to your tank (depending on what type of a heater you have) and then connect the hose to the drain valve. Making sure that the other end of the hose is in a large bucket or safely placed into a storm drain, open the drain valve and let the water start to flow out. While this is going, you should also open your temperature and pressure relief valve.
After a few minutes, start collecting a bucket of the draining water to inspect it. If there are still sediment crystals in the bottom, then continue letting the water drain through. When the crystals stop appearing in the bottom, simply close up the drain valve and allow the tank to refill. Then restart your pilot light or turn your electrical connection back on and your tank should heat up again!
Tankless Water Heaters
Tankless water heaters don’t have a tank of water, so naturally they don’t have a giant reservoir where mineral buildup can accumulate. But they often do need to be flushed out once per year. Minerals like calcium and magnesium can form into a nasty buildup in the lines and pipes, especially where the water is quickly being brought up to temperature. Flushing a tankless water heater often involves the use of specialized flushing fluid which is designed for this job, which means the job is best left to a professional.
