15-58 3 speed circulator that ran almost silent for about five or six weeks is now rattling constantly when running no matter what speed it's set on. This was installed new in Oct along with a boiler. The noise is transmitting to all the baseboard piping and we're having to use white noise to drown it out. Since it was as silent as its Taco predecessor for several weeks should I try to get it replaced under warranty? Baseboards are heating well and are quiet except for this rattle coming up the pipe.
