Help with a single pipe Gould Jet Pump.

If I did not cover the problem you are having, please check out the posts on the Forum

You can also post a question on the forum.

Well single pipe jet pump, common problems, how to prime and setup. 

On this page we will explain how a Gould single pipe jet pump works and a few common problems, that are simple to solve.

I call any well pump that is not a submersible pump a jet pump. 

A shallow well up to about 100 feet deep can use a jet pump with just a single pipe.

With a foot valve at the bottom of the well.

Deeper wells require a pump with 2 pipes and a special fitting on the bottom.

It is really is best to have a pro help you with a 2 pipe jet pump, they can be very difficult to troubleshoot, when it comes to dealing with the pipes and fittings going into the well.

If a well is too deep you need to go with a submersible pump.

Some problems are common on both single pipe and two pipe Gould jet pumps.

Problem 1 my pump runs all the time and never shuts off, but I do get water all day.

This problem is caused by a faulty fitting at the bottom of a 2 pipe well system, the fitting needs to be pulled and cleaned or replaced.

Problem 2 The pump has high pressure, then it drops to nothing, then it jumps back to high again.

Or it will stay low for some time and come back later.

When the pressure is low the pump is not pumping.

This is caused by a bad pressure switch, or a clogged fitting connected to the pressure switch, or the tubing connected to the pump housing and the pressure switch, this needs to be cleaned out.

The fitting connected to the pump housing needs to be removed from the pump, and the tapping in the pump needs to be cleaned.
