Is there a solution to a very loud flapper motor? running M3015A DE435 model, the motor functions, Flow rate are spot on, calibrates to Spec, but very loud motor as compared to other modules.
any solutions besides replacing motor? Can I coat the internal flappers or motor rubber membrane with silicone lube?
I would greatly appreciate insight as well. Like what causes a loud flapper motor, or is it really the flappers that are causing this. etc
thanks
