Hello, I just purchased an Intex Auto Cleaner, hooked the hoses up as directed, hand tightened. My problem is, I do not have good connections, they leak, some pretty bad. The cleaner did not come with washers or any instructions to tighten the connections (hand tightened all again once running, everybody tight). Vacuum does not move, troubleshooting in owners manual says the hoses should be tight with no leaks to allow in air. Any suggestions on how to fix?
