Abstract
An auxiliary system for insuring adequate water supply during peak periods from a well with a low recovery rate. A gravity storage tank is replenished at a rate equal to or slightly lower than the recovery rate of the well. A float-controlled air shutoff valve prevents overfilling and allows water to drain from the storage tank to supply a pressure-responsive pump. The pump, together with a diaphragm pressure tank, supplies normal household use at varying flow rates, drawing its peak requirements from the gravity storage tank.
Claims10
A system for periodically supplying water from a pressurized water source, which is replenished at a normal recovery rate, to a user supply line at a peak rate of flow which exceeds the normal recovery rate at which the water source is being replenished, said system comprising:
- a water intake control valve having an inlet connected to said water source and adapted to discharge water at a flow rate which is slightly less than that of the water source normal recovery rate,
- a storage tank having an inlet connected to receive water from the water intake control valve and having an outlet arranged to discharge water by gravity flow from the storage tank,
- an air flow shutoff valve responsive to water level in the storage tank and arranged to shut off the ingress and egress of air in the upper part of the storage tank when the stored water reaches a selected level, and
- a pressure responsive pump having an inlet connected to receive water from the outlet of the storage tank and having an outlet communicating with the user supply line, said pressure responsive pump being adapted to pump water from the storage tank when the user line pressure drops below a preselected minimum value and to shut off when the user's supply line pressure rises above a preselected maximum value.
A system for periodically supplying water from a pressurized water source, which is replenished from a low yield well at a normal recovery rate to a user supply line at a peak rate of flow which exceeds the normal recovery rate of the well, said system comprising:
- a water intake control valve having an inlet connected to said water source and adapted to discharge water at a flow rate which is slightly less than that of the well recovery rate,
- a storage tank having an inlet connected to receive water from the water intake control valve and having an outlet arranged to discharge water by gravity flow from the storage tank,
- an air flow shut off valve having a float responsive to water level in the storage tank and arranged to shut off the ingress and egress of air in the upper part of the storage tank when the stored water reaches a selected level,
- a pressure-responsive pump having an inlet connected to receive water from the outlet of the storage tank and having an outlet communicating with the user's supply line, said pressure-responsive pump being adapted to pump water from the storage tank when the user's line pressure drops below a preselected minimum value and to shut off when the user's supply line pressure rises above a preselected maximum value, and
- a diaphragm pressure tank connected between the user supply line and the outlet of the pressure-responsive pump and adapted to reduce pressure variations and to augment the water supply during periods of peak flow.
