A properly done Submersible Water Pump Installation in a properly constructed water well can be trouble free for may years. Here is how to go about installing a submersible water pump properly.

Inspect the well, looking for signs of external damage to casing, check the depth and standing water level

The first thing you need to do when carrying out a Submersible Water Pump installation is to check the well total depth – the distance from the ground level to the bottom of the well. Head – A vertical distance from the pump to the ground level where water is discharged or into a pressure tank. GPM – the amount of water in GPM the pump produces

Inspect the supplied components

The proper equipment is essential  Submersible Water Pump installation so check the details on the submersible motor looking for power supply rating, identify whether it is a 2-wire single phase, a 3-wire single phase and needs a pump starter box or 3 phase configuration. Check that the submersible pump drop cable suits the motor cable and motor and is correctly rated for submersion in water. Check that the fittings match the outlet on the pump, the rising main and the bore cap.

Fit motor to submersible pump

Use supplied grease to lubricate and seal splined shaft on assembly. Tape poly pipe or lay flat fitting with thread tape and screw into pump.

Splice drop cable to motor cable with supplied cable splice kit

When the drop cable must be spliced or connected to the motor leads, it is necessary that the splice be water tight. The splice can be made with commercially available potting or heat shrink splicing kits. Follow the kit instructions carefully.

Lay submersible pump assemble next to water well

Fit rising main to pump and roll out. Fit bore cap to the other end of rising main.

Roll out drop cable alongside rising main

Attach stainless steel safety cable to pump and roll out with rising main and drop cable. Attach safety cable end to bore cap allowing for the rising main to stretch. 

Attach the drop cable to the rising main with 4-6 turns of grey duct tape every 4–6 meter (13.1–19.7 ft) apart

You can also use zip ties. Allow some slack for the rising main to stretch. You can tape the full length of the cable splice to the rising main to protect it. Allow a couple of meters extra drop cable to be doubled up and taped to the rising main below the bore cap. This might be required if the cable splice or motor need replacement at a later date.

Check that the fittings are tight, check the cables are secure and slack to allow for stretch.

If the weight of the assembly is light enough to handle, gently lower the pump end into the well with an assistant to hold the bore cap end. Feed the assembly down the hole, pay particular attention to preventing damage to the electric drop cable. The assembly should be suspended by the bore cap on top of the casing.

If the weight of the assembly cannot be safely handled a roller made from a car wheel may be used

Attach bore cap to vehicle with a sling and “D” shackle. Position roller over well. Position vehicle to allow the pump to be lowered into well. Drive vehicle toward well. Lower the last meter by hand if possible or allow the well cap to bump over roller and into position on the casing.

Connect pump starter, pump controller and pump protection device to power supply and test pump. Allow a few moments for the water to reach the surface.

On completion of the initial test proceed to connect the required pipe work to the bore cap. Finally test pump operation and operation of pump protection devices and controls.

  1. I am also interested in pumps, especially industrial pumps. This article on 9 steps is really good and I find it useful for me. Thank you.

  2. Hello
    What about the installation of a big pump (submersible)of 22kw which is 120kg?
    What about the mechanisms and angins to be used?
    Thank you
    Waiting for an answer

  3. Shukrani kwa kunisaidia kuelewa kwamba vifaa vilivyopaswa kupatanishwa na ufungaji sahihi. Hii inaonyesha jinsi muhimu kuajiri mtaalam ni. Mimi nitashiriki makala hii na ndugu yangu kumshawishi kuajiri moja.

  4. Hello!I looking for a new water pump.I saw a similar one on another site and it seems perfect to me.But before I spend the money,I would like to hear your opinion on the device!

  5. It really helped when you said you need to inspect your well’s depth before installing a water pump. My wife and I want to start our house’s construction project, and we’ve heard installing a water well comes with lots of benefits. That’s why we are researching how to install one and what we would need. We’re grateful for your advice about what steps to follow to successfully install a water pump.

  6. Very helpful and informative post. Recently l’ve installed a 0.75 kw single-phase pump and still it rends a good service. Just want to know, how long does it may lasting? Thanks for the nice post.

  7. It made sense when you said that components like the motor and drop cable need to be inspected before the installation begins. My uncle is looking for a company to replace the submersible pump on his large plot of commercial land soon. Asking about these specific steps should help him find a reliable pump service for the job, so I’ll have to share your advice soon!

  8. Na pump yangu ya kisima nilivyo hama nyumba nimeifungua hipo tuh naiuza nataka 350,000/= yani bado mpyaa. mwenye kuihitaji ani cheki +255786999567

  9. l’ve installed a 0.75kw single phase borehole pump it’s turning but doesn’t pump water What could be wrong

  10. how do i know where to connect the capacitor and the light wire,so it can rotate in a right way

  11. It’s great that you touched on waiting a few minutes before the water reaches the surface. My brother wants to build a new well on his property this summer. I think it’s a great idea because he can finally have his own water supply.

  12. Comment:Hence am an electrical expert i hv been installing Electrical water pumps without any problem …
    and my customers like ..my job and are ever proud of my job

  13. Thank you so much for sharing 9 easy step for installing a submersible water pump. By following these step anyone can install pump. Good job keep it up.

  14. I’ve been planning to have a Well installed in my yard because I heard that it can help reduce my water bill. I’m glad you shared this; I’ll make sure to lubricate the seal splined shaft on assembly. I’ll also keep in mind to attach safety cable end so the rising main will stretch.

  15. I’ve intstall a submersible pump in a reservoir tank that pump water to a backyard garden that works well on timing my problem is water still flows a little when pump is off and this can drain the water in the tank. What can do to stop it

  16. I completely agree that you should inspect the well before you put a pump in. You want to make sure that it doesn’t have any damage. That way you won’t have to worry about doing repairs while the pump is in there.

  17. what can you use to check water level and how deep you can fix the pump from water level

  18. Checking that the fittings are tight is a great idea. I am sure that this could solve a lot of preventable problems that people might have with piping. A friend of mine looking into bore water would appreciate this tip.

  19. Thanks for helping me understand that the fittings must match for proper installation. This just shows how important hiring an expert is. I will share this article with my brother to convince him to hire one. He just needs to have a water well since he said that he needs to cut costs, especially with rising water bills.

  20. For me, I would probably attempt to install it myself, but I would probably fail at it. Now as you said, you do need to inspect the well before you even start the pump installation process. That way, you can be sure that any potential problems will be taken care of. If anything, I would get someone to come and do it for me.

  21. That’s good to know that if you lower the pump end into the water that you’ll have to make sure that the bore cap is on top of the casing. You definitely want to make sure the pump is put into the water correctly since that it the component that provides you with water. My sister is planning to install a submersible pump for her home but neither one of us know what the bore cap is or how to ensure it’s on top so we’ll have to find a professional that can install it for her.

  22. I didn’t know there were so many steps that go into installing a water well pump. My husband has been talking about using a water well pump instead of the traditional one we have currently. However, neither of us are confident we could install one ourselves, so we will hire a contractor to do it for us.
