I just had a new Pentair FNS 48 installed a week ago.  Just as the original owner described above, It is blowing DE and Dirt back into the pool.  Techs came out twice.. First time took filter apart, then took the multi-port apart, checking for any possible reasons for DE and dirt blowing back into the pool. They said everything was good.  Then we turned the filter back on and the same problem existed. The next day, they Re-plumbed everything, thinking the chlorinator was the problem.   Unfortunately none of those efforts worked.  The problem still exists. Water is cloudy. Chemical levels good (have my own Taylor test kit).



Sounds like this is a manufacturing issue.
