Forum Discussion
The SHurflo 4048 is recommended as 'direct replacement' for the Shurflo 5.7 Variable Speed pump
It is rated for 4 gpm at 55 psi
It has an internal bypass valve to control low flow shutter (allows pump to run continuously during low flow demands vs stop/start/stop/start action)
As for that Aquajet 55.........
Might be an installation issue, air leak or controller
Installation...Operation Manual
Troubleshooting starts pg. 16
