Achieved badges:
01.
Q: Why is a lifting station an optimal solution for basement refurbishments?
A: A lifting station is flexible, easy to service, cost effective, provides protection against flooding and is odour free. It can also be connected to the existing drainage pipe easily.
01.
Q: Why is a lifting station an optimal solution for basement refurbishments?
A: A lifting station is a versatile solution that can handle both black and grey wastewater, drainage water and surface water.
01.
Q: Why is a lifting station an optimal solution for basement refurbishments?
A: The built-in frequency converter makes the lifting station very flexible for fluctuations in the discharge profile of the sanitary appliances.
02.
Q: How can you tell if you need to establish a drainage system as part of your building project?
A: If the building next door does not have a drainage system, your building does not need one either.
02.
Q: How can you tell if you need to establish a drainage system as part of your building project?
A: When the projected area of a building exceeds 2.000 m2 a drainage system is required.
02.
Q: How can you tell if you need to establish a drainage system as part of your building project?
A: By conducting a thorough pre-investigation of the conditions of the soil, the groundwater conditions, and the drainage situation on neighbouring lots.
03.
Q: Which inlet options does the Grundfos MULTILIFT offer?
A: DN32-DN100
03.
Q: Which inlet options does the Grundfos MULTILIFT offer?
A: DN50-DN150
03.
Q: Which inlet options does the Grundfos MULTILIFT offer?
A: DN40, DN65, DN100 and DN150
04.
Q: What are the approaches that can reduce hydrostatic pressure on your building?
A: Constructing a robust foundation, anchoring the building to the underground, or installing a drainage system – or all three in some cases
04.
Q: What are the approaches that can reduce hydrostatic pressure on your building?
A: There is no need to reduce the hydrostatic pressure as it adapts automatically to the weight of the building.
04.
Q: What are the approaches that can reduce hydrostatic pressure on your building?
A: Using the help of the local water supply company to once a year pump away the rising ground water around the building.
05.
Q: Why can it be a challenge to install a pumping pit outside a building when removing grey or black wastewater from below sewage level?
A: The weight and the shape of the pumping pit depend on the soil conditions, saturation of the soil and the local regulations. This makes planning difficult.
05.
Q: Why can it be a challenge to install a pumping pit outside a building when removing grey or black wastewater from below sewage level?
A: The pumps in an outside pumping pit cannot be controlled from a Building Management System.
05.
Q: Why can it be a challenge to install a pumping pit outside a building when removing grey or black wastewater from below sewage level?
A: A pumping pit installation calls for longer planning and installation time, more excavation time and higher excavation costs, as well as a higher initial investment.
06.
Q: What makes the Grundfos MULTILIFT easy to install?
A: You only need to set the following in the controller: 1) the maximum number of starts/stops of the pumps and 2) the level of the high water level alarm in the controller.
06.
Q: What makes the Grundfos MULTILIFT easy to install?
A: The system comes pre-assembled with a freely adjustable inlet and many other installer benefits
06.
Q: What makes the Grundfos MULTILIFT easy to install?
A: The system comes pre-assembled and all settings in the controller are set from the factory.
