The jet pump should have a 3/8" plug at the top of the pump,, where the water comes in from the well. Remove plug, and fill that port up as much as you can, turn pump on,,and keep filling with clean water,,[any dirt that gets caught in side the venturi it will not archive priming],,once the port is full the motor will start singing a different tune,, you will know when it starts pulling water because you will hear the load on the motor,,and water will start to come gushing out the port,,quickly install the 3/8 plug, [make sure the plug has pipe dope on it before you install it] at that time it should start pulling water,and once the pump reaches 50 or 60 lbs. The pump will shut off. If it does not hold the prime the 1st time repeat by removing the 3/8" plug again . It may take a few times before the pump holds its prime.

Can you replace a two pipe jet pump with a single pipe jet pump?

Yes you can if the water level from the inlet of the pump is less than 25 feet. That's the limit of a shallow well jet pump. It can lift water physically 25 feet vertically, no more. If the well casing diameter is three inch or larger you could also install a submersible pump.[url="http://www.pumpsandtanks.com/Pumps/jet_pumps.htm"]Jet Pumps[/url]

How does a jet pump work in a water well?

The most basic jet pump has a round pump chamber containing an impeller. The outlet to the well is large and the outlet to pressure tank is small. When the pump is primed and switched on it will suck water in and expel it at a higher rate. They are very susceptible to air leaks -every connection MUST be airtight.


How does a jet pump work in a water?

There are two types of jet pumps. Deep well jet and shallow well jet. The deep well has it's jet (ejector) in the well. The jets come in two different configurations. Two pipe and single pipe. The two pipe uses two pipes lowered into the well to the existing water level with the jet on the end. The single pipe jet is hung in the well with only one pipe. The jet has two leathers to seal it to the casing making the casing the second pipe. The shallow well jet pump has it's jet on or in the pump. These pumps can only lift water 25 feet. Once primed, the jet pump will force water down the pressure pipe into the jet, where it will be sent through a nozzle (of differing sizes depending on pump and water level) and into a Venturi tube (also differing in sizes) which creates a vacuum that will send more water up to be captured in the storage tank.
