Hello! Hopefully someone can give me some advice. I recently set up an Intex Ultra Frame 20 x 52 pool. I have the sand filter hooked up and working properly, but I am having an issue with the Intex skimmer - the kind that hangs off the side of the pool, and I am not even sure it is an issue with the skimmer per se. What happens is when I attach the adapter to the inlet (screws on to allow the skimmer hose to connect) I get air in the pre-filter assembly and the pressure gauge goes to almost zero. There is no air prior to connecting the adapter. I have not even connected the skimmer hose when this occurs. As soon as I unscrew the adapter and pull it away from the inlet, the pre-filter fills with water again, pressure goes back up and seems to be fine. Am I doing something wrong? It almost seems like the intake is not able to provide enough water through the smaller opening of the adapter. I also have tried the vacuum adapter and had similar results.
Thanks in advance
