Site volunteers have now fitted low pressure, wide-bore seal nozzles to all the float valves on the troughs, and are happy to report that the filling rate has been improved on them all, often dramatically.
However, notwithstanding, there remained one trough which was still rather slow to fill, near to plot 86.
On investigation, it turned out that there were two buried stopcocks in the supply as well as the one above ground, and that one of these was the wrong way round. That is, the supply pressure would tend to press back the washer and shut off the flow. This was the problem, and it has now been resolved.
