Plenty of suction when removing skimmer basket but no suction at end of hose when attaching only 1 section using regulator/reducer and very little flow to pump.

Hi Dennis.  Be sure your cleaner,  cleaner hose, and vacuum regulator are not clogged up with debris, and check your vacuum hose for leaks.  Be sure the hose is not collapsing upon itself as well.  All of those issues can cause the problem you are describing.
