Hi All I was adjusting the OPV valve on my Lelit Elizabeth, turning the cylinder (bolt) clockwise to reduce the pressure. However the turns introduce a twist in the tube/hose that connects to the OPV valve, to the extent that the twist causes a spray leak at the connection point. I was trying to get 6 bar, but couldn’t due to the above. Here is a photo of the kink in the hose: [URL=https://i.imgur.com/Cx3Svqb.jpg][IMG]https://i.imgur.com/Cx3Svqb.jpg[/IMG][/URL] So I moved the position of the hose to reduce the kink, which allowed me to get to 6.75 BAR: [URL=https://i.imgur.com/7Huq27b.jpg][IMG]https://i.imgur.com/7Huq27b.jpg[/IMG][/URL] [URL=https://i.imgur.com/fkYxLIh.jpg][IMG]https://i.imgur.com/fkYxLIh.jpg[/IMG][/URL] I was nervous about (and did not) disconnect or reconnect the hose, as I feared losing a tight connection, or not being able to reconnect. Btw, if I shift back to more than 7.8 BAR, I will introduce another kink in the hose, and have to revert back to the former hose routing. Surely there is a better way. Suggestions? Thanks, JHCCoffee PS 6\.8 BAR did not improve the taste of my decaf, so I changed to 7.8 BAR and will hopefully dial that in tomorrow. But that is the subject of my separate post on brew pressure.

Lelit Elizabeth OPV Adjustment - Causes Hose Kinks - Solutions?

JHCCoffee - when you twist the OPV screw, you are twisting the hose with it. This setup is not designed to do what you did: it’s intended for minor adjustments only. I suppose now you know why.

The only way to untwist the hose is to apply the same principle of when you have a twisted electrical cable… unplug it, untwist it, re-plug it. You don’t need to unplug at the OPV end… you can unplug at that X fitting. But… as you said, once you lose that tight fitting, it will become lose - believe me, I know from experience. So, whatever you do, make sure you have a cable tie in hand and you secure that connection.

Remove hose.
