Additional question. The outlets of the Best & Lloyd drippers are designed to have a non return valve in the outlet union, a flat disk with light spring. These are omitted on mine and I have not tried fitting them. Does anyone have any experience with them?
The same here, not fitted. Did not even know about those. I do similar valves fitted on my Flyer but that has been converted to rubber seals and a throttle controlled pump so a totally different story.
