I have multiple problems with my pool, but thought I would start with the simplest problem, and work my way to the most complicated.

I have attempted to attach a picture, but it is difficult to tell in this format if the pic is attached.

I have a leak at the hose on the booster pump. Not certain what this hose is for. It seems to go into the ground, perhaps attaching to other pipes underground.

It is this hose at the connector that is leaking, not the connector to the booster. I tried to remove the hose and the connector, but was not certain how to remove it, and did not force it. Can anyone advise me how to repair this leak?

Also, there is a silver band around the booster where the connecter seems to connect to the booster. Can you tell me what this is for?
