610 three way drain valve on water system

[Yerfdog]

I have broken the lever arm off the spring loaded water drain valve next to water tank in side hatch of my chausson 610. Can anyone help with a replacement component suggestión
I apologise for no photos but the vehicle is still in garage after breaking down in southern France with injector problems it took 4 month to recover and since the recovery the garage cannot find fault or reluctant to admit it as I’m currently in Australia back next week for showdown .

Is it the two step drain in the Technibox? With a bit of reworking of the pipework the one suggested by Diabalo would work.

Link below to a YouTube video of the one in the Technibox and how it works.
