Just had a look at it, and visually it looks fine, but it does leak slowly. A bit of plumbers tape around the thread would more than likely stop it. If i get time I'll give it a go and test it. Failing that you could probably go to Clarke rubber and get a softer bit of rubber for the seal, so it contacts closer to the plastic.
It really isn't a big deal as your meant to drain the water regularly anyway
