Zero cost adapter for portafilter pressure gauge
CIV; Like yours, my portafilter has a hole between 7 and 8 mm in diameter. The inside of the hole is unthreaded. The Presta valve stem has an outside diameter under 6 mm and it passes through the hole in the portafilter and is held in place with the nut that normally would fit on the valve stem if

After a little head scratching it occurred to me that I could make an adapter out of an old presta style bike inner tube valve stem that would be able to pass though the portafilter hole and let me measure pressure with a bike pressure gauge (to fit presta valves). Cut the valve stem out of an old t...

Question about valves on 2 group Elektra HX
On my Elektra 2 group there is a line from the right HX pipe to a safety valve that empties into the drain pan (not to be confused with the boiler safety valve atop the boiler). While I am pulling shots a significant amount of water passes through this valve to the drain pan. There seems to be more

Low Water Alarm On When Tank 3/4 Full

Using water level sensor with RO bottled water
I live in well water country and use purchased bottled water for my elektra. I am concerned that the water level sensor may not work properly with some very pure water (hasn't happened yet, but it makes sense that if all the ions are removed by reverse osmosis or distillation then the water wouldn't...

Question about valves on 2 group Elektra HX
Thanks a lot. Actually I had them apart several times for cleaning etc but I hadn't paid much attention to the valve seat. I will play further
