I wasn't going to take a very long walk on this nice spring evening; it just happened. I was going to knock off a path or two on Brandon Hill, home over centuries to hermits and windmills, cannons and Chartists, and then just wander home, stopping only to fill up my milk bottle at the vending machine in the Pump House car park.
However, when I heard a distant gas burner I stayed on the hill long enough to see if I could get a decent photo of both the hot air balloon drifting over with Cabot Tower in the same frame (spoiler: I couldn't. And only having the fixed-focal-length Fuji with me didn't help) and then, on the way home, bumped into my "support bubble", Sarah and Vik, and extended my walk even further do creep carefully down the slipway next to the old paddle steamer landing stage and get some photos from its furthest extreme during a very low tide...
According to the Whitley Pump (twinned with St John's Conduit!) website:
Carmelite monks constructed St John’s Conduit, to carry water from the nearby spring to a friary that occupied the site now occupied by Bristol Beacon (Colston Hall as-was.)
It still carries water to a fountain outside St John the Baptist Church on Quay Street, which I'll have to go and have a look at—it's the church at the end of Broad Street, where National Westminster Insurance Services, my first employer in Bristol, used to be.
Presumably some of it also used to pop out here, but that's just a guess. The map of medieval cellars and conduits seems only to show a pipe passing near here from the Jacobs Well spring, not from the St John's source, which looks to be in Berkeley Square.
There's a bit more info here.

A fruitless wander, as Spoke and Stringer (who I thought might do a decent flat white) were closed, and the only other harbourside inlet offering were a bit too busy to wait at, especially as I'd spent some time wandering some of the convolutions of Rownham Mead. This last congeries of dull alleyways and brown-painted garages was at least somewhere I've never been before, in parts.
