What are the Components of a Well with a Two Line Jet Pump Refer to the illustration above right, courtesy of Carson Dunlop and also to our rough sketch provided below to see the components providing well water to a building served by a two line jet pump located apart from the well. In our drawing the two line jet pump which draws water from the well and the water pressure tank are shown located separately from. The actual lift capacity will vary depending on the pump horsepower and other factors such as piping length, bends, diameter. Common lift height is about 3. For example, a twin pipe jet pump plumbing arrangement requires typical specificationsA well bore of 4 in diameter or larger regardless of the wells flow rate we need enough space for the piping, well jet, and other components. A 1 14 diameter suction line. A 1 diameter drive line this is the line down which water is pumped to bring more water back up by sending the drive line water through a water pick up venturi device in the wellA 4 or 5 well jet the venturi device that picks up water from the well bore in a 2 line jet pump system. A foot valve on the bottom of the jet assembly or on the end of a 3. The tailpiece avoids over pumping if the well flow rate is less than the pumping rate. Well pits such as the one weve drawn are used especially in climates exposed to freezing weather, as a way to get. In addition to showing a well pit in this sketch, we discuss and illustrate well pits a bit more. WELL PITSA more modern device, the pitless adapter which permits a water tight piping. Components of a Drilled Well with a Submersible Water Pump. What is the Pumping Capacity in Gallons per Minute for a 2 Line Deep Well Jet Pump A two line jet pump can typically raise water from depths of 3. At WATER PUMP CAPACITIES TYPES RATES GPM we compare the pumping capacities of one line jet pumps, two line jet pumps, submersible well pumps, and other water pumping methods. A nice example table of Deep Well 2 Line Jet Pump Capacities for 12 hp and 1 hp deep well pumps is provided in the Water Ace Jet Pump Installation Manual and excerpted below to illustrate the factors that determine well pump capacity. Both of the charts below are for 2 line jet pumps produced by Water Ace. Line jet pumps intended for deep well use and made by other manufacturers can be expected to have similar capacities. The Water Ace charts shown in part above make clear that the capacity of a deep well pump to deliver water at a given flow rate varies by these factors the depth of the well the bottom scale in the two chartsthe pump horsepower the color codes indicate pump model and horsepower HP variationThe well pump model the right hand table is for the companys more powerful well pump series of 2 line jet pumpsThe condition of well piping, including pipe diameter, length, number of bends or elbows.

How a Two Line Jet Pump Works to Get Water Out of the Well. A two line jet pump refers to the observation that two pipes are connected between the jet pump and the well. In our photo at left you can see the two black plastic lines leaving the front of the water pump. A two line jet pump draws water out of the well by magic it forces water away from the pump and into the bottom of the. At the bottom of the well water from the jet pump. Water flowing through the venturi device at the bottom of the well piping draws still additional water out of the well and into. The requirement to have some water to send down to the well in order to bring a larger quantity of water back is why a two line jet pump cant provide any water or water pressure in a building if it loses its prime. See WELL PUMP PRIMING PROCEDURE if you need to re prime your jet pump. In our sketch above see the two arrows showing water entering the bottom of the piping. The following list and definition of two line deep well jet pump and water well parts and terms is. A pair of well pipes leave the well casing through a water tight cap on top of the casing and. The well casing top in this example is located inside of a well pit but it. It is particularly important that the well cap on the casing be water tight. Many well caps are not water tight, which is why modern drilled well casings extend above ground level. Compression Seal Well Cap is a special well cap with openings to permit passage of the two water lines and maybe an air vent tube. A compression seal well cap consists of steel top and bottom plates which sandwich rubber fittings which surround. As the two plates are bolted together they squeeze the rubber sandwich gaskets causing them to expand and seal both around. See WELL CAPS COVERS for well casing cap sealing venting requirements. A two line jet pump is shown outside of the well, either inside of the building or perhaps in a well pit or well house. Two line refers. Since the lift capacity of a two line jet pump is not. Our sketch shows the pump connected to a water pressure tank which in turn supplies water to the. The pressure tank is usually located very close to the jet pump but it could be elsewhere. Well Jet and Well Piping Foot Valve is a venturi device through which the two line jet pump sends water to collect and. See WELL PIPING FOOT VALVES for details. You can see Carson Dunlops sketch of a foot valve HERE Image and also at the end of this list. Well Piping Tail Piece some wells may contain a tailpiece at the end of the well piping a device designed to prevent jet pump damage if well water falls too low. If well water drops to an unsafe level the tailpiece recirculates water to keep the pump from running dry. See WELL PIPING TAIL PIECEWell Jet Foot Valve Clearance from Well Bottom not shown means that the well piping, bottom venturi, and foot valve are inserted. We need this clearance to reduce the tendency of the well pump to pick up mud and debris from the bottom of the well. Static head not shown in this sketch is the height of the column of water inside of the well between the bottom of the foot valve and the. We discuss static head and well recovery rates in detail. WELL FLOW RATEWhat is the Well Piping Foot Valve used in a well and what goes wrong with foot valves If you keep losing prime at the water pump where a two line jet pump is installed, its probable that a check valve at the pump or more likely atthe FOOT VALVE in the bottom of the well needs to be replaced. See WELL PIPING FOOT VALVES for details about this component. Carson Dunlops sketch at left shows how a foot valve works and where it is installed. Replacing a foot valve in the well requires that the well be opened and the well piping be pulled out to permit removal of the old valve and installation of a new one. After replacing the foot valve you should shock the well since youve probably contaminated it by laying your well piping and parts on the ground and foot valves at the plumbing supplier are not kept in sterile containers. We discuss how to shock a well. WELL SHOCK CHLORINATION PROCEDURE our WELL SHOCKING GUIDE2 Line Jet Pump Well Pump Diagnostic Table.
