Henry caught fire a few months ago so i'm bodging together a cyclone. I'm using an old expansion tank and a bucket. Just about to weld the top and side pipes . Should the top pipe go down below the level of the side pipe?
Yes or you won't get a cyclone action - it'll just draw stuff direct from the side pipe up the outlet.
Actually it works OK with the suck just at the top. I use a converted plastic dustbin with 50mm PVC fixed to the lid. Have to admit to looking at a Veritas lid before I started The cyclone effect is caused by the lower pressure in the tank pulling in the waste carring air at a tangent, so it centrifuges the waste to the edge and, out of the relatively narrow tube, it slows down and drops.
