*solved* Which Jabasco Joker Valve?

[macca499]

Evening all - have a Jabasco electric head on my yacht, outlet seacock always open so waste passes through the holding tank and straight out to sea. Have started getting some back flow after each flush so assume joker valve is faulty. I don’t have any documentation for the toilet and can’t see any name plates on it so wondering if anyone can identify the model or even the model of joker valve required from attached photos

Many thanks in advance

ok after looking online, am nearly certain it is the lite flush model so have ordered a joker valve to suit, also note previous threads about not using household cleaning products.
