Why the sump pump doesn't work until you have to push the float?

If a sump pump doesn't activate until you manually push the float, it may indicate that the float switch is stuck or malfunctioning. This can happen due to debris in the sump pit, a faulty float switch, or improper alignment of the float. Additionally, the pump may not be receiving power or have electrical issues affecting its operation. Regular maintenance can help prevent such issues and ensure the pump functions correctly when needed.
