If the vacuum gauge reads 25", then rest assured that the pump is capable of lifting water 25 feet (assuming that the suction hose and fittings are correctly applied).

If the pump has been checked and it pulls 25" of vacuum, then the problem will be elsewhere and you should refer to Pump Troubleshooting Guide.
