De-kinking your hoses is really very simple. Do this with one hose at a time, and with any new hose before use: Take your rolled up (just as it comes out of the package) hose, and use a (non-swivel) connector to connect the two ends of it so that water cannot get into the hose. Now, fill a pot with the hottest water you can get out of your tap. Submerge the hose and leave it in there for 10-20 minutes. Then remove it, dry off quickly with a towel, remove the connector, and unroll it, stretching it out straight, with a small weight holding ends straight for a few minutes. This will remove the "set" the hose took while coiled up and let it lie nice and flat and straight. Once it is cooled completely it should stay straight. It may sometimes take two attempts to remove the set, but after that you should have no further issues. If it coils back up later on in use, just repeat the process. I also specify the soft "good" tubing from my provider. They send the good soft Salter Labs hoses. Some people use a heat gun, but I don't recommend that with the multi-channel hoses we use. Just good shower-hot water is warm enough. Also, in normal use, never roll/coil the hoses up - that will just make it take a set again. This also why I don't use a reel.
