I circled the water drop in the picture. It's not coming from the hose connection and running down. Coming from inside the fitting. Is this a simple o-ring replacement? Or should I just order a new head/attachment? I noticed it did this since new, but only a drop or two after cleaning filter and filling from tank and would stop. This past time, it has not stopped. I have a towel under it for now as it's a tiny amount of water, but i still want to fix it.
