Ta Candace. I nearly broke my pump trying to prime it using the above bad advice. This is not the way to prime a well point.

Technical Details

Thanks to De Wets for fixing my pump properly. Great Service from all. Andy, thanks for your comment - do you have any pointers as to the correct way to prime a well point?

Used above advice and it worked brilliantly for me. I was about to call De Wets who installed it years back. Main thing Iearnt is that alway rather close your stopcock first before switching off the pump. My water pressure is very low, I do not have a stopcock from my wellpoint to my pump but a non-return valve on the pump. When I prime it as explained the water from the municipal tap just pours out of the hose from the pump to the garden. What to do to get the water pressure up again?

Hi my suction pipe coming from the ground to the pump, crimps all the time when i use my well Point pump. Can you assist me with this problem? I found that there is no suction on the inlet side of my pump. SI if I take off the black irrigation pipe coming from underground and if I hold my hand over the intake valve, I do not feel any suction. Is this correct? Hands-on Technical Tips. Monday, 2 November WellPoint not pumping water any more?

If your well point pump has stopped pumping water this could be caused by a few problems. Another common reason for the pump not pumping is a leak in a join or in a pipe.

Pump systems are particularly sensitive to air holes in the system. Check all pipes carefully for tiny holes — you might even have to dig up the pipes to examine them : The non-return valve the brass fitting on the front of the pump prevents the water from running back down the hole when the pump is not running may sometimes jam, causing the pump to lose prime.

Sorry, we're unable to complete your request

Here are some tips to avoid losing prime and rectifying it if is does occur: 1 Make a habit of shutting off the water stopcock on the pump before switching the power off.

The reason for not opening the stopcock fully is that the pump needs water in the casing to create the vacuum to draw the air out of the system, and opening the stopcock fully would empty the casing. You will notice that the water will trickle for a minute or two, then start spluttering as the air is expelled.

After about 4 minutes you should notice that water starts to constantly trickle out again. Repeat steps ii to v if necessary. Thanks to Precipitec for these tips! Tips: Some well points that have a low yield operate more efficiently if the stopcock on the pump is choked back until the pump has a faint hissing sound. It is advisable to have a cover over the motor of the pump, and these can be bought from any Pool Shop. The iron content can be tested at a Pool shop for a small fee.

If you find that your water stains the walls, you can minimise this by only watering the sections near the walls very early in the morning or at night. This gives the water a chance to drain off the walls before the iron can oxidise.

Do not leave your pump unused for longer than a montheven in winter.

Often pumps that stand unused develop corrosion in their bearings and give problems, so even in winter run the pump for a few minutes a week. Do not run the pump with the valve shut off for longer than 15 minutes.Wellpoint dewatering is widely used for excavations of shallow depths, especially for pipeline trench excavations.

In appropriate ground conditions a wellpoint system can be installed speedily and made operational rapidly. A typical wellpoint system consists of a series of small diameters wells known as wellpoints connected via a header pipe, to the suction side of a suitable wellpoint pump.

The pump creates a vacuum in the header pipe, drawing water up out of the ground. For long pipeline trenches, horizontal wellpoints may be installed by special trenching machines.

Wellpoints are typically installed in lines or rings around the excavation, and are pumped by diesel or electrically powered pumps, with associated header mains, water discharge pipes, power supply generators, electrical controls and monitoring systems.

A wellpoint dewatering pump is used for lowering the groundwater level during construction work. The PT positive displacement pump is by far the best choice to guarantee a dry pit during site dewatering.

These pumps are usually diesel driven and feature a sound attenuated canopy. The pump can also be supplied with an electric drive or in open frame. Choose a PT wellpoint pump. The PT wellpoint pumps are positive displacement pumps and fully self-priming.

They can handle any mix of water and air without requiring a separate priming system. The pump creates a vacuum via the header pipe and starts lowering the groundwater level. Watch the Dutch dewatering video to see the most cost effective way to ensure a perfectly dry construction pit.

This simple type of well is a great option for homeowners who live in an area with sandy or loose soil. Sand points drive through the soil to the water table and use pumps to get water to the surface. These wells don't usually yield as much water as more modern driven wells, but they are useful for emergency water or for livestock and crops.

If your soil is high in clay or contains many large rocks, a sand point well may not be the best choice for your home. However, if you're seeking an inexpensive well installation option and your area's water table is within about 30 feet of the surface, a sand point well might be a good choice for you.

Though wells have been drilled far into the earth, sometimes as far as feet, those depths are hardly feasible for a casual do-it-yourself project. A sand point is a perforated pipe that drives through the earth and provides a channel for water to be pumped to the surface.

Installation of a sand point well first requires the driving of this piece down to the level of the water table. Note that the water table will fluctuate throughout the course of the year depending on the weather and precipitation.

In addition, depending on your jurisdiction, you may need permission to dig a well. To begin, select the location for your well and prepare to drive your sand point into the ground. Generally, you should dig your well at your property's highest point to prevent contamination by wastewater runoff.

The sand point should be 24 to 60 inches long and have a heavy steel point. It should also be screened to keep out larger dirt particles. Overall, the sand point needs to be strong enough to withstand hammering or driving into the earth.

Attach the sand point to a rigid pipe. The pipe must also be strong enough to withstand being forcefully drilled into the ground. You should use a cap on the exposed end of the pipe to protect the threads from wear and use.

Next, drive the sand point and pipe into the earth using a driver. Be sure to leave at least 18 inches of pipe extended above ground level so that you can attach a pump.

Once you have driven your sand point and pipe into the earth, you will need to verify that you have hit the level of the water table. To determine where the water level is and how deep you will need to drive, lower a weighted string or rope into the pipe. You should be able to hear it when it hits water. Once this has occurred, drive the sand point 5 feet deeper to allow for seasonal water-level fluctuations.

Once you have dug the well, you will need to install a pump assembly. Most homeowners installing their own sand point wells choose either a pitcher pump or suction pump.

Assemblies for either type of pump are available in kits or at home improvement stores. Before use, you will need to flush the pump and pipe of dirt.JavaScript seems to be disabled in your browser.

When working on a construction site it is of vital importance to have an effective solution for controlling the groundwater level. The PT wellpoint and sock dewatering pump is the best choice around for ensuring a dry construction pit. These pumps are typically supplied diesel driven and with a sound attenuated canopy.

Video set up well point system. The PT well point pumps are positive displacement pumps and fully self-priming. They can cope with any combination of air and water, with no need for a separate priming system. As soon as the pump is attached to a well point dewatering system, you just need to start the engine and you can head off home. The pump produces a vacuum via the header pipe and starts to reduce the groundwater level.

To drive it I cut a 6 inch whole in the driveway and put a smaller diameter pipe one foot longer than the well point in it to pound on with a twelve pond hammer and filled the point with enough sand to prevent the other pipe from wedging into it.

I then covered the hole with a nice looking grate. The ground under my driveway is gravel about four feet deep. This well point is much better than what's at Ace. It's built like a tank. You won't be dissatisfied with this unit. I'll be the only kid in town with water during the Armageddon, tee hee. This is top quality above and beyond what I ever expected.

I used the drive coupler, and the threads were destroyed immediately.
