How to Remove Build Up Rust on Water Heater?

Water heater really plays a vital role in many households, especially during the winter season. Without a functioning heater, many homeowners would have to endure a freezingly cold shower every day. That is why many household owners ensure that they already find water heaters for sale before the winter season comes.

Fortunately, there are many reliable heaters in the market that you can avail of. In Florida, water heaters are very affordable and of high quality.

However, after many years of usage, you may find yourself in need of a specialist due to water rust. When you do not address this problem, it might cause further issues with your heater. If your budget is very limited to seeking water heater services, here are a few things you can do to remove the built-up rust in your water heater.

Draining and flushing the tank

To eliminate built-up rust from the bottom of a water heater’s tank, drain the water. First, turn off the power and turn off the water supply. After opening a hot water faucet to admit air, connect a hose to the outlet drain and flow the water outside or into a sink. Most of the sediment may be flushed out by continuously filling the tank with around five gallons of cold water and draining it completely.

Brushing and draining rust

Once the tank is empty, use a wrench to loosen the drain valve and remove it to gain access to the bottom. To dislodge the rust, use a long, thin brush that fits through the aperture. When it comes to removing the silt, you will then have the following options:

  1. Connect a hose to the outlet drain to replace the valve, and then flush the tank many times by filling it with about five gallons of water and letting it drain.
  2. Make use of a vacuum cleaner.

Using a vacuum cleaner

You can modify the vacuum’s hose to fit within the drain aperture by using 3/4-inch polybutylene. Wrap duct tape around the hose opening to secure it to the hose and create an airtight seal. After vacuuming, begin brushing and then vacuuming again to provide the most thorough clean possible. Remember to replace the valve once completed and cover the threads with plumbing tape to ensure a watertight seal.

Replacing sacrificial anodes

According to specialists, because the sacrificial anode is designed to decay, it must be replaced regularly. This lengthy rod, which screws into the tank’s top, is commonly made of a metal that corrodes faster than the steel walls of water heater tanks. The metal you pick for your anode should be determined by the sort of water you utilize.
