Talk:Hydrostatic loop

Dead / unhelpful links
The first explanatory link is dead, and the second doesn't really help much. Anyone know of any better ones? I was hoping to find out, for example, if this is an actual "loop" (as in water could theoretically circle around it endlessly, or at least flows "backwards" in terms of the main flow direction at the top), or more of a(n inverted) U-bend, but even that isn't really clear. Particularly as the marine version doesn't say anything about needing to be 33ft / 10m tall (higher than some 2-storey houses!), merely "above the waterline even when pitching heavily".

Ding ding! Help needed from a plumbing (or toilet) expert please! 51.7.49.61 (talk) 18:31, 27 August 2017 (UTC)
