Jura Original Membrane 70158  Pressure Regulator - for water pump

Part Number: 70158, 71143, 71771, 72516, 72809

The membrane pressure regulator regulates the water pressure flow within the Jura machines.  Without this pressure regulator, the pump will be a lot noisier and will not regulate the required operating pressure.   In addition, this part leaks frequently and therefore is the most frequently replaced mechanical component in Jura machines.

ENA 8 System Filling Issue

After my ENA 8 started to show System Filling message and stopped making espresso, I did a thorough research and this part was identified as most likely culprit. Trying to find it online wasn't easy. Likely, I stumbled upon this site. They have very reasonable price so I decided to purchase from them. Not directly from here but from their ebay listing. Same company, same address in Bulgaria. Part came 3 weeks earlier than they promised, so it was a very welcoming surprise. Item was adequately packaged and true to the description. Twenty minutes work (multiple videos available on YouTube) and my machine is back online. Can't thank this guys enough. My local Jura authorized repair company wanted 17 times more for repair then this part costs. No brainer.
