System works fine- cut-in/out pressures correct (45 seconds from cut-in to out), draw down OK (about 9 gal. 32 gal. Water Worker tank.
But- considerable air in line pushed into tank at start-up. At cut out, pressure immediately drops about 2lbs. and then holds steady. Some water hammer at start-up.
The water hammer is at check valve just before tank.
Must there be a leak in the line for air to enter, or could a vacuum have the same effect (assuming the check valve at the pump is defective)? Help would be greatly appreciated.
