If this question should be on a different group, please let me know; I
don't want to create clutter here.

We have a Hayward Pool-Vac Ultra that is powered through about 35 feet
of 1 1/2 inch (sections) hose. The hose is frequently twisted into
loops that keep the vacuum from cleaning all of the pool. We have
replaced the gear-box, but that didn't help. What we think would help
is some kind of a swivel joint that could be placed between sections
of the hose, but we have not been able to find any such coupling. Do
any of you know of something like this, or do any of you have any
other suggestions on what we can do to eliminate this hose looping?

'Sorry if this question is off-topic; I just don't know where else to
ask.
