I've bought the avon sized self-bailer adapter and plug myself so when it arrives I'll know if it's possible....
Just had a look at polymarine , looks like a good site .
I can't see any sort of drain that would suit the valiant hull drain in the form of an auto bailer . They have deck drains that look similar to the valiant ones .42mm i think and Iam pretty sure its a standard plumbing fitting size . I got a new nut from a plumbing fitting today so after the weekend I will try it . My LSX repair looks solid now its dry so will; leave it there for the weekend to prove its the deck bailer leaking.
Seamark nunn sell the actual Valiant deck drain , so may get a whole new one for the sake of few quid . It seems to me the fitting may be better with two flat rubber washers as you would use on a sink etc instead of sealant which always seems to fail in the end and is then a mess to clean up and get sealed again
