What causes noise at water supply line? 

 

¼” copper tubing when not secured to solid surface near cooler will cause water hammering, all the way down the copper tubing to where it is connected to solid supply line. Secure 1/4”copper tubing with rubberize hose clamp. On AeroCool coolers, secure ¼” tubing within 18” where tubing is attached to side of wet section.
