I'm looking for some help researching how to clean long tubes, such as maybe 1/4 inch pickup tubes for a water pump that may be 20 feet long. I've been able to find hydration bladder cleaning kits that allow for cleaning the first 2 or 3 feet of these tubes, but beyond some sort of high pressure/high flow system with high caustic cleaning solutions, I haven't found a good way to swab out a long tube.

I have wondered many times how a human would fare if the kidneys dumped urine into the start of the large intestines somewhere about the appendix instead of into a bladder to be sprayed out. I'm assuming water would be reabsorbed and slower to process out, primarily through sweat and evaporation from the lungs, and maybe diarrhea, though it may be that other waste products, such as salts or ureas may be absorbed into the large intestines instead of being ejected, though I have no idea if it would, or if it would be ejected as intended. Do we have any biologists here that could give insight on if combining both waste paths into one would be advisable?

I'm running a Radeon 6770 on my home machine, running Mint and running Baulder's Gate 3 under Steam, and have been having some surfaces sparkle or not show correctly when running it with Vulkan in Proton, though everything looks perfect when using DirectX. It also looks correct in both modes when run on Steam deck. What is this phenomenon, just a bug in my graphics driver and Vulkan? None of my other games exhibit this issue.

I just changed my stock Ender 3 hotend to a Volcano to get back to a more durable printhead after wrecking my Creality Spider head and have gotten it to where I can print something monolythic (like a brick or boot dryer type thing that doesn't have much actual detail) without much issue, but printing something with any detail, such as a character piece for DnD results in an absolute whispy disaster. I'm still trying to print stock recommended speeds and stock temperatures (PLA at 200C, PETG at 240C, etc at 50 to 75mm/s) and retract from none to 9mm trying to find something that works. Nothing does so far, even when I go to playing with temps (PETG 200-260C, PLA 180-240C) Where should I set my baseline settings to be able to get close to the CR-10 head that I started with? I originally upgraded to the Spider, which is now discontinued, because of printing ASA and the CR-10 creating a lot of jams as the bowden tube degrades inside. I have also heard good things about the Volcano and was curious about them. I'm still running the stock extruder, btw. I'm betting my problem is simply that I don't know how to use this head yet, though I guess I could have gotten a dud.
