This is probably a really stupid question but..
I have one of those Zodiac Barracuda G3 cleaners attached to the port in the pool wall. What is the correct way to disconnect it when it is not needing to be doing its thing? The port has a spring loaded cover that shuts when the vacuum hose is not inserted.
Do I have to turn off the valve at the pump before disconnecting? If not, since the door on the pool wall port is shut, will it create some type of negative pressure or something?
I'd hate to have to turn the valve every time, as it's really difficult to operate, like it's stuck. In fact I don't think I can even get it to full close. But I want to make sure I'm doing it right.
