Some updates - pictures still to come, similiar picture to pump in message:
The model is a "JSW-100" which I can't find a thing about.
Max Heat (maybe head poorly translated?) 7m
Max Flow - 85 L/min
Motor Output - 100w (Input: 250w)
Weight: 4kgs, 145x160x270
It can pump down to 3mm of floor - looks a lot like this:
Doesn't have the float switch, has 1" hose adaptor, can be fitted with 1/2 and 3/4"
