Thanks for this very informative, I have a question I changed my shower head element followed instructions made sure its tight and as per guidelines. But the new element has a humming noise when you put it in hot and very hot settings in low setting it has no humming noise. what may be the challenge? thanks in advance.
@@edwinkimani4557Yes you might have connected it the wrong way.. I noted that when you connect the live in on the live out the light remain on the ON and off position.
