Gaggia Selecta opv moddding

Jamiep

Hi I have recently bought a second hand Gaggia Selecta not straight Classic unfortunately. I would like to alter the pressure but it appears there is not an OPV fitted to these, are there any instructions etc in how much work would be needed for this change to be made? Is it even possible to do easily - do I need to change quite a few parts, may not be worth while doing?

Jamiep Welcome to the forum, I would think @Norvin may have done a few

I don’t think that it’s possible to alter the pressure on the fitting that fits on top of the pump. Your best option is to change the boiler inlet fitting for a Classic OPV, which will fit in its place. You should also change the fitting on the top of the pump for a plain elbow and block off the air bleed outlet on the steam valve.
