I remodeled my kitchen, and I had planned for a plumber to install the dishwasher. I may not be able to get one for quite a while, so I feel like I should try to do it myself. I'm okay at plumbing, but I'm just very nervous about leaks. It's a Bosch 300. I used a dishwasher connector kit and attached an elbow to the plastic garden hose connection. I hand tightened it then did a little more with pliers. I hope that I didn't overtighten it. I've also read that you have to be careful about crossthreading. I then tightened the braided stainless hose and did a 1/4 turn with a wrench. I was planning to test it with the dishwasher pulled out, but I realized that my braided line is too short to make the water line connection. For purposes of testing, it is okay to get some type of coupling and connect two braided lines together? Once I can confirm no leaks, I could then push the dishwasher in, remove the coupling, and attach the braided line. I could always just use a larger braided line, but then it will be coiled under my sink. If I see no leaks after turning on the water, does this mean that I should be okay? I wasn't planning to run it until it's pushed fully in and secured. I may put a leak detector back there for peace of mind. I appreciate any suggestions/advice!
