@Paul .I have been watching it a while. The collar does not seem to have made the water surface any oilier, but really its too early to tell. I do notice on the water, from time to time some kind of oily film. I have read it has to do with ground water bulbing out of the ground and something to do with bacteria and iron content. Does anybody know more about this ?
Notice how one side flares out for the sticks to connect together. On the pipe section that connects to the elbow of the Monk you take the rubber gasket out. This is what allows the monk to pivot.
It is also important that you have a long connection to the elbow.
I have installed the elbow as described but what is this long connection? Also, if you take out the gasket water leaks into the elbow creating a small leak and the elbow seems loose. The wind can knock the pipe over when the pond is not full. Is there something Im missing? Thanks for the info besides that i found that pipe nice to work with.
and seem to not only think outside the box, but don't even know of the existence of the box. In a lot of cases, that's referred to as Autism. I have two sons who have it. And everything is black and white with them, no in between.
As a kid I thought the same way, then realized it is 90% grey with bands of black and white at each end.
Something that Holzer writes in Desert or Paradise seems worth mentioning here. I'm not sure if this is the same as the "collar" idea, I think it isn't. it's to prevent fish from escaping down the pipe (if you don't want them to go down it, I gather).
Every monk needs a safety device to prevent fish swimming through it. Conventional monks have a slit-plate installed before the dam planks. For the Holzer Monk I use the pipe-in-pipe system. I slide a pipe that is about 5cm in diameter larger over the vertical pipe. I use an angle grinder to make the slits and waterproof the end with gauze or builder's fleece. A spacer keeps the pipes in place. The pipe with the slits should be at least 10 cm longer than the viertical pipe. This prevents fish from swimming through and allows sufficient water flow. This also helps to keep leaves out of the drainage pipe. (p. 73, Desert or Paradise, Sepp Holzer)
Note--it seems the horizontality of the opening isn't sufficient to keep leaves from getting into the pipe (perhaps clogging it?). And this will work even when the Holzer monk is in a lowered position, not just when it's at full height.
Does anyone know why you need to waterproof the end? isn't that part always going to be out of water? I understand making it fish-proof, but not sure why a screen wouldn't be sufficient. Nor how gauze makes something waterproof...
Also, there's such a thing as a regular monk, and a Holzer monk. Regular monks are adjusted by removing some planks from the stack of planks, and Holzer's innovation (that someone else seems to have invented also) is to make the L-shaped pipe that can be adjusted.
