[QUOTE="chuck c, post: 133842, member: 2907"] I can only find 90, 45, 22.5, and 11 degrees and they are a couple bux each. 90 Tees are everywhere but 45 wye fittings are rare and expensive, like $13 each. Since I just can't get there with off the shelf angle fittings in either PVC or copper, I've been looking into bending. Over in old England it seems to be common practice to bend copper plumbing where possible because it's faster, cheaper, and two less places to leak. Makes sense. They have internal bending springs for this but I can't find them in US sizes. But if I can find any plain old spring that will fit snugly into 1" it should work. Another way it's done is by filling the pipe with fine sand or salt and crimping the ends. These are both to keep the tube from collapsing when bent. Heat can also be used. This will make nice gradual bends ideal for flow. I'm going to tinker with designs using a mix of bent tube and standard fittings to see what they look like. [/QUOTE]
