Some products may have roles more centre stage, but take one part away and you and your pump could be in danger. In this post, we take a look at a variety of products for submersible pumps, what their roles are and how they work together. Let's take a look. A submersible pump allows for moving water from the ground up.
They are designed to push the water up to the surface in a very efficient way. The placement and number of check valves required for a system is based on the depth of the pump setting in the well. Installation of feet or less require one check valve on the pump discharge and one on the surface of the well. Settings feet or deeper may require multiple check valves. Some thing to consider during installation is the weight of piping, water and submersible pump, head loss of the valves, friction loss of the piping, velocity of water and water hammer.
For more on check valves and what their job is, check out taking a look at check and foot valves. Easy tie adapters thread into the discharge on the check valve at the submersible pump and inserts into poly riser pipe.
A second adapter can be threaded into the pitless adapter at the well head and then connects to the poly riser pipe. The lug with a hole, or the rope eye, provides a simple means to securely fasten the safety rope or cable or to secure the submersible pump to the well head in case of a pipe failure. Available in bronze and stainless. Hose clamps are designed for sealing poly pipe to barbed insert fittings, making a positive watertight seal and pull-off proof connection.
Using an all grade stainless steel clamp ensures the clamp will last the life of the system for water well installations or where maximum corrosion resistance is required. For a more in depth look at clamps, check out The pro's guide to gear clamps webinar.
Heat shrink splice kits are designed for under water electrical connections between the pump cable and the leads on the pump motor. The connection is made by cutting the cables in a staggered position to decrease the outer cable diameter. This is an important step in order to reduce the risk of damaging the splice due to abrasion when the pump is lowered into the well. Torque arrestors are specifically designed to keep the submersible pump centred and to prevent any twisting in the well casing.
Torque arrestors also protect the pump cable and are typically installed directly above the pump on the riser pipe. On by inspectapedia. A 2-line jet pump uses a venturi valve at the bottom of its pair of water pipes water down one and more water up the other to bring up water from the bottom of a well or from a pickup point in a lake or water tank.
A river water pump could also work with a 1-line jet pump as long as the TOTAL vertical lift from pick-up point in the river to end use point is less than 27 ft. A 2-line jet pump, in comparison, can lift water hundreds of feet. It is the flow of water through the valve, not the depth of the valve, that allows the system to work.
Putting the pick up point for your river water pump deeper into the water makes no meaningful difference in the pump's ability to deliver water. At about 30 ft.
But the depth of a river water pick-up for a 2-line or 1-line jet pump can be important for other reasons: 1. In a well that may be ft. In a river or lake a similar depth is probably safe though on lake pump systems I've examined in New York, Minnesota, and other US states often permit the pump to sit on the very bottom when the bottom is fully covered by large rocks.
In a lake or river water pumping pick-up system it's generally better for the pick up point to be more-distant from the shoreline. Particularly in large lakes where distancing from the shore is actually achievable, getting more than 10 meters from the lakeshore reduces the level of shore-sourced bacteria and other pathogens that will be delivered by the water system.
Deeper is better or worse? Does anyone know where I can order one? I have a two pipe well system in a 2" casing. The suction pipe goes to the bottom and has a foot valve. The pressure line just pushes water through the cap and fills the gap between the suction pipe and the well casing.
My well stopped supplying water. I've used my neighbor's hose to prime the pump but in the end, the pressure pipe builds pressure but the suction line produces no water. We lost all water in the house. I had a spare pump so I swapped the old one out so I assume that part of the system is working. It seems to me that I must have some sort of issue with the suction. The pump is connected to the well head with plastic pipes on barbed fittings. There seems to be water leakage from both the lines between the well head to the pump.
Could this be the problem? Or is there something else I should check? Anonymous, I think so, in that if we fill only the down-pipe, when it pushes water up from the foot valve in the well and the injector therein all of that air that was in the riser-pipe the larger diameter pipe will be pushed into the pump; the result could be that the pump impeller becomes air-bound.
On by mod - replace injector in old 2 line jet pump. Larry: If you are trying to replace the front end of an old well pump tat's no longer sold, you'll probably have to buy a new jet pump. That's because pump front-ends or injector assemblies aer not universal. But before throwing-in the towel on your old pump, take it to your local plumbing supplier to see what they have at hand.
My existing one has rotted and i need to locate a new injector. Is anyone still making them? Thank you. Raguram If no settings such as the pressure control switch were changed then the problem may be loss of water at the source, such as a well, used to fill your tank, or the pump itself may be failing - a clogged or dirty impeller. We are using jet pump for water delivery in over head tank. Becky If the toilet was running continuously that may have run out water from your well.
Try this: 1. Leave the pump off for an hour or more - giving the well a chance to "recover" 3. Corey Check the manufacturer's instructions. Some jet pumps, but not all, can indeed be converted between 1 line and 2 line versions by seapptng the front end or impeller assembly.
Ok so my house set up is for 1 line the jet pump that i got is for 2 line jet pump can i cap it off or exchange the front.
On - by mod - Could a two line jet pump be used as a single line by merely plugging the pressure line? No, in that Arrangement - just plugging one of the lines means that your 2 line jet pump won't pump any water. It may help to understand how a 2 line jet pump actually works; the "pumping" occurs when the pump sends water DOWN to the venturi that's at the bottom of its pair of well pipes.
There water squirts through the venturi, causing a larger volume of water to return back up the larger of the two 2-line jet pump pipes and onwards into the building water system. Blocking either of those lines means no water. But some jet pumps are convertible to single line from two line by changing the front end of the pump to a one-line jet pump system. Dennis: The ejector in a 2 line jet pump needs to quite close to or even below the surface of the water, in the well, though you'll see in our ejector tailpiece illustrations that it does not have to be at the very bottom of the well piping.
Otherwise it can't generate the required lift. To be clear about how your 2 line jet pump is working to deliver water to the building in the building or somewhere above ground a 2 line jet pump includes an impeller that pushes water down the smaller-diameter well pipe and near the bottom of that pipe, in the well, water is pushed through a jet or venturi - an opening shaped like a funnel.
The venturi, by reducing the opening size in a funnel shape, increases the speed of water passing through the venturi - also called the "injector".
That increase in water creates a suction that draws additional water up through the tailpiece, into the injector, and the combined volume of water sent down the pipe plus additional water sent up the larger pipe back to the pump is what actually delivers water into the building. The maximum length of the tailpiece is 25 feet. Click here. Customer Reviews Read more All merchandise listed is in stock.
