Hello it appears as though I have a leak right where the filter housing sits on the surface of the hot tub (see pictures attached) it’s either this or the leak is coming from the upper part of the 2 jets in the corner shown, I just think the waterline really indicates it’s more at the filter. My question is am I able to remove and reseal this portion from above the tub or do I need to get under it? My understanding is there’s a bit nut below so if I twist that top in reverse will it loosen that nut? Will I be able to retighten? Is there an o-ring there or do I just silicone it? Are there any videos out there that explain this process?
thanks in advance
