Electric feedback from water circulation pump

I have an electrical hum coming from my speakers (95 db sensitivity) whenever my whole house well water circulation pump turns on (which occurs anytime a faucet or shower is turned on).  I have a dedicated 20 amp line to my listening room and this line is at lest 7 feet away from the pump.  I believe the noise is coming from energy back fed from the pump into the breaker box.

I contacted my well company and they indicated this is a problem that usually affects TV images (mine are fine) and recommended I install a capacitor at the breaker box which will absorb the back feed of energy coming from the pump.  I did this and there was no improvement.

I just had a Powerworx clean energy/surge protector added to each of our three electrical panels due to a recent lightening strike of my house (an ounce of prevention... I know).  It was also purported to likely help the above issue.  It did not.

My next move is to either invest in a power regenerator or power conditioner for in my room.  If that does not help then my final move might be to install a pressurized holding tank so that the pump does not run as often.  I am unsure of the cost or feasibility of this and therefore reserve it as a final option.

Any recommendations regarding power conditioning in this specific situation are welcomed.  Thanks!

Thanks yogiboy for the advice.  I will look into it.  Fortunately the space is not an issue.

Thank you all for your kind help.  Sorry for the confusion about the hum vs hiss.  No transformer hum to speak of, just speaker hiss.   I have a Subdrive 20 submersible pump controller by Franklin Electric.  It was installed three years ago when the house was built.  So this is actually the well head pump controller that is making all the fuss.  I also have a small (maybe 4 or 5 gallon) blue pressurized tank by Gould’s water technology called a hydro pro - not sure what it’s role is since the pump is frequently cycling on and off with the slightest drop in water pressure (ie water usage).   Nevertheless when a faucet is turned on the pump controller is running.  I contacted my well drilling company today and they said they only install underground cisterns and referred me to a plumber who was clueless as to a solution and thusly sent me to another well drilling company who is going to get back to me tomorrow.  They have big kahuna status on internet review sites so I am hopeful they will provide a solution.  I’ll let you know what turns up tomorrow.

Thanks helomech.  I'll check the Humdinger out.  From what I know of that type of device it mainly takes are of the transformer humming.  My issue is more with hiss coming from the speakers.  Might be worth a try.

Thanks Mike for your contribution.  I just looked it up and agree with you, it's expensive.  Easy to overlook things like that during a custom build.  Too many choices and decisions.  

I'll check with SubDrive to see what options they have.  I have not yet heard back from the other well company.  I'll try again.

Unfortunately this issue has not been resolved.   I put a large capacitor into the pump controller to absorb back feed which helped only a little.  I then bought a Shunyata power conditioner which has helped though not completely.   So I try to listen when others aren’t home or awake or just put up with it.  Turning up the volume helps but that of course doesn’t replace the loss of low level detail.  I’ll have to look into the VFD controller as recommended.   I was next thinking of getting a PS Audio Powerplant to give regeneration a try.
