Hello All! I am having problems keeping my pool clean. I have an approximately 30,000 gallon, freestyle shaped in ground pool. It has pentair pumps, a waterfall feature, a vacuum line and a skimmer. I have used a Creepy Krauly cleaner since having the pool built around 10 years ago. It has a cartridge style filter which I clean regularly. The Kreepy Krauly seems to have stopped working recently so I replaced it with a new, generic version. I have noticed for the past few months that I have had to move the main valve (that regulates the suction between the vacuum and skimmer lines to get enough suction to power the Kreepy Krauly. I am also having to clean the cartridges much more frequently that I have had to in the past. i replace those cartridges last year with generic ones, instead of the original Pentair. The chemistry in my pool is pretty good, but it seems to be a constant struggle to keep the cleaner going. I have checked the lines for blockage and they appear clear. I have also noticed that if I hook a small section of the Kreepy Krauly hose and hooked it into the skimmer port it causes the suction to rise significantly and the cleaner works much better, but I know that it's not supposed to work this way. Any suggestions as to what could be causing such an issue? Thanks in advance for any help
