While on Vacation...
If you have been away from home for more than seven days, the following steps should be taken to minimize any stagnating odors.
First, run water from an inside tap long enough for the grinder pump to begin working. After the pump turns on, turn the water off. The grinder pump will run until the tank is empty and will shut off. This process will cleanse the pump and leave it filled with a minimum of clean water. Always leave the electrical power on. This allows the heating element inside the pump to operate which helps eliminate condensation and freezing.
By following these guidelines, you can ensure that your low-pressure system will provide many years of safe, reliable service.
