We are trying to drain our spa for the first time, but cannot for the life of me get the cap unscrewed! I have called the dealership and they recommended a hammer/wrench to loosen it up, but it is not budging. Apparently it should screw right off with no problems. I really don't want to pay a $75 service visit for this... Are we just not strong enough or are we just missing something? Has anyone had this problem before?
We have tried using a wrench, but it's a pretty awkward angle and we are going to ruin the plastic if we try much harder. Any suggestions?
To clarify, the small black cap is what will not move. The larger black area behind the small cap will turn, but not all the way. From what I understand, the small part should come off so that I can attach the hose, and then the part behind can be pulled out and turned so that the water flow will begin.
