I couldn’t find an overflow pipe lying round at the end of the garden (see yesterday’s post) but it did get me thinking that maybe the best solution would be to join the slightly-too-short pipe I did have to another one. Ideal for that would be a couple of large jubilee clips, which I didn’t have. Again, I began thinking about 3D printing solutions but then I remembered that I’ve got some clamps that came with the polytunnel. Since some of our side benches are just rested on the supports rather than clamped in, it means I’ve got spares.
It turned out they were just the right size and gave a solid connection. I’ve gone from tubing portions that were a little too short to a joined one that is almost twice as long as it needs to be but that means it can do the job while not being under undue stress. Now I’m keenly waiting for some rain so I can see how it works in practice.
