Gotta admire a guy who has a favourite diverter valve!

Finally somebody with a brain and a thorough explanation cheers John Wilson

So glad I watched this.. I had our boiler apart 3 times trying to figure out why the hot water wasn't working. Had replaced the mixer, the diaphragm and was about to replace the diverter.. Turned out it was the thermostat in the upstairs shower was making its own circuit between the cold and hot !!

Well you’ve got to really admire this guy as he slowly winds up the enthusiasm for his subject goes into overdrive and really shines through :-) ... fired up ( sorry!) he manages to light that same flame in you also. Great old fashioned tech instruction

Very clear and concise, definitely gave me an insight into the operation of the valve in my particular boiler. Thank you for taking the time to produce and post the video.

Great to see People helping others out
