When we moved into our house in 2016, the electric water heater popped loudly when heating. After awhile, I researched and realized that it was likely due to limescale and/or other sediment buildup. I flushed it multiple times, but never got it to stop popping, so I eventually decided to replace it.
I replaced the water heater myself in 2021. It was whisper quiet when heating. Now, after just a couple years, it is making a hissing sound. It's not popping, but it is hissing. Here's a video where you can hear it:
Again, with this newer water heater, less than 2 years old, when it started hissing, I drained and flushed it. After draining, I flushed multiple times before filling it up again and turning it back on. Yet it still makes this hissing noise. Everything I've read says that draining and flushing is the way to deal with this, but it is not helping. The water heater heats just fine, but the noise is an annoyance, especially to my wife.
Also possibly worth mentioning is that we added a water softener around 2018.
What is the next step to deal with the hissing noise? Should I just keep trying to drain and flush it, hoping it will eventually get it cleared? That hasn't helped so far, so I'm not inclined to keep doing it. I don't know if there's some type of cleaning/descaling solution that can be poured into it to help, or if there's something else I should try entirely.
Can someone let me know what the next step would be and/or how to actually effectively deal with this?
