We’ve recently bought a Hilka multi-purpose siphon kit from Screwfix, mainly to transfer dirty bath water to a water butt in the garden to water plants with. For £10 it’s great. Might be worth a look for what you need?
Cheers, I had a look, but I already have a 3/4" hose ( bigger better for siphon I believe) and that one uses a smaller hose. Thinking of having a punt on the lomo bilge pump to prime the hose then detach while submerged might work.
