This is just all sorts of cool... I did have some issues on first usage with the inner piston being latched in the seal (and therefore not letting through water). After some use, things seem to be better though, hoping it will relax a little bit more. Gabor: brilliant piece of kit!! {image}

Assuming the assembly is the same as an ES3 (which I believe is identical as far as lever attachment): just leave the E clip off?
