Boiler Mate WH7L noise

Helping a friend on this one.

A Boiler Mate WH7L makes a noise sounding like something between a plucked guitar string and a woodworking shop planer. First it's really loud and then it resonantingly tapers to silence over a minute or two and repeats. Happens several times a day regardless of water use.

What could it be?

Sounds like a flow control. If it has one open it up all the way and see if the sound stops.. Since no heat is being used you can leave it open for test purposed..

I haven't opened the panels on the blue tank.

Is there anything within it, specifically the lower third, can can present a resonating sound through the nearby pipes?

Can't use tinypic on this forum for some reason.

Use photobucket.com instead.

a plucked guitar string and a woodworking shop planer.
Could be worse... at least it doesn't sound like a banjo string and a radial arm saw!

I can't think of anything inside that bottom section that would cause this, all that's in there is the piping in and out of the tank.

When was the last time the tank was flushed?

Ya know... stranger things have happened, but if it were me I would not rule out a defective leaking toilet valve.

I had one years ago that HOWLED like a banshee ... I mean LOUD!!!! resonated through the pipes in the entire house... it occurred as the toilet tank was about 2/3 full until it filled. When that toilet valve leaked a bit and the toilet refilled itself every couple hours, it did the same thing. I finally got off my butt and fixed the darn thing...

I think the note was either a C-flat, or an E-sharp.

Could it be a zone valve trying to open and the spring is twanging while the gear is stripped? And it just keeps trying to open, then clicks closed, then open, then closed....etc..

But the boiler would no fire with end switch..????

Think I saw one do that once many moons ago....

Only if there's one within the tank. I've never opened it, but for sure, the sound is originating from the lower third of the tank.

Was told the local plumber, a handyman of sorts, in the rural area where the tank is only scratched his head looking into the noise. Should it be significant, this is on very hard well water and at 8,600 feet.

I have to look up the specs on the boilermate as I forgot if it has a jacket or coil... If a coil you can try cleaning it...
