We recently replaced our electric water heater.
Ever since, we've experienced smelly water (that was expected) and a crunchy-gurgling sound in the showers, accompanied with a sudden pulse of water. It's the sound/pulse that I'm trying to troubleshoot.
You'll be standing in the shower with the water running, then you'll hear this crunchy-gurgling noise gradually coming through the pipes, then a pulse in the spray. We aren't seeing this in any of the sinks, though.
This sound is different from what I recall water-hammer being. That's more of a sudden "slam" from a valve being closed somewhere in the system and inadequate air chambers in the plumbing. This is more of a gradual "release"...like it's part of the water flow.
Could this be connected with the smelly water in anyway? Does that process result in gas pockets in the lines?
FWIW, we are on a well, with the attendant pump and pressure tank. I might suspect the tank, if we were seeing this noise/pulse problem everywhere, but, since it's just the showers, I'm not sure. I have no idea how to trouble-shoot the tank.
Any help will be appreciated.
