I like the ads about Shurflo quiet ones.....what do I "need"? IF I were to change pumps.
Finally found the pump; it is under the closet floor through a trap door.
My suggestion would be to isolate the cause of the chatter first. With the pump running, hold your hand on it and see if it quiets down. It might have come loose from it's mount.
Next, follow the pressure and suction line and see if it rubs against a wall someplace. The lines vibrate in sync with the pump, and often are the real cause for the noise. If that's teh case, then it would be loudest just before the pump shuts off after you close the faucet.
If indeed you need new pump, and don't mind spending alittle money, then I would suggest the pump/accumulator combination that is offered by some of the pump manufacturers. Those usually run very quiet, and provide a very smooth flow of water.
