Couple of questions. Is it just a matter of connecting the pvc for water in from the tank and water out, plugging it in, and go, or is there more to it? I once saw someone use an airblower sort of thing to fix a pump that was cycling too quickly and wondered if such a thing had to be used at set-up. Second question - where should you fit 1 way valves in the piping? The diagrams that come with the pump only show taps at various points, but no back flow controls so perhaps not needed?
For town water which has enough pressure to feed to a tank, install a 2, ltr tank at ground level with a normal toilet cystern cut off valve to stop the taank overfilling. Connect the pump to the tank as a low-pressure connection. If you have a two-storey house, connect a non-return valve in the outward feed to stop backflow to your pump. Before you turn on the pump for the first time, prime the pump.
There should be a plug on the top of your pump for this purpose. The small water tank prevents your pump from pumping dry if your town water is not working. Normally a 2, ltr tank will give you a day buffer against town water stoppage.
The water tank also prevents the pump sucking the incoming mains dry and creating a negative pressure. If this happens you will draw in foul water from outside the mains including sewerage via a myriad of leaks in the street.
Could you explain a little more on what I need to do here. For example, do I losen the plug until water appears then close it? Yes, that should do it. If not, screw the plug completely off and fill the pump with water using a jug or something similar, then rescrew the plug securely to form an airtight connection. When you turn the pump on, just listen to it. You will easily tell if it is sucking air. A minute or two sucking air fill not ruin your pump but it is not advisable to leave it too long.
When this happens, the pump is primed. Also, if you find the pump is cycling when nobody is using the water it will mean that you have pressure loss in your outward feed ie probably a water leak or a leaking tap.
I drink the rain water, my wife still prefers to buy the water that the local monastry sells - god knows where that comes from - probably the local water supply. This means you can turn a tap down low, say in the shower, without the pump cycling. I bought one from Oz for our place in Issan Interestingly the sales staff did not have a clue about them or their purpose. The model I have has a small relay which switches the actual motor current so is cheap to replace when it eventually burns out Some pressure switches can burn out in a matter of months depending on how the pump cycles.
Using Crossy's diagram, the by-pass line from the town supply to the delivery side of the pump unit with NRV is only of use if the town supply has sufficient pressure to be useful should you have a power failure or pump problem.
In the case of having very low pressure from the town supply as I doyou are better off not using this arrangement as it only introduces another maintenance problem the NRVif this valve leaks, you end pumping water back into the town main and the pump will cycle or run continuously.

At this point attach the pipe dog below the coupling. If using a derrick with a long enough boom, this is the first point where you stop and clamp the pipe.
Take the drop pipe apart. Unscrew the pipe out of the top of the coupling. Do not unscrew the coupling off of the pipe below. If the pipe is galvanized steel pipe, inspect each section for rust. Replace with new galvanized, or Sch. Take extreme care with the pipe in the air, as you unscrew it as it is heavy, and serious injury or damage may result to persons or property hit by the pipe as it comes to the ground. Take care with Sch. Take care to not damage the threads on the pipe or couplings.
Use the piece of 2" Sch. Repeat the process until you have the pipe and pump out. Follow manufacturer's directions to attach your new pump. Run a continuity test on the wire you just pulled with the old pump, if no obvious defects were found. If there is continuity, reuse. If not, replace the wire. The wiring kit should have three butt connectors, and three shrink tubes. Slide the shrink tubes onto the pump wires before connecting the wires.
Crimp well, so the wire doesn't pull out of the butt connectors, and seal by centering the shrink tubes over the connections, using the propane torch to shrink If you have a 6" or larger well, there will be a torque arrestor it looks like a rubber football with four pieces missing Make sure it is in good condition. Replace if needed.
INSTALL A SUBMERSIBLE PUMP: 6 Lessons for Doing It the Right Way
Not having it enough will make the torque arrestor ineffective. Chlorinate the well with a few 10 or so chlorine pellets or a few cups of liquid bleach. When installing well pumps, debris and rust is stirred up in the casing, and bacteria can get in through the top, which can cause problems.
Reverse the process used to pull the pump. Be sure to tape the wire well, and use enough pipe dope on the threads. Lower the submersible pump into the well casing with the winch or derrick line. Clamp with a pipe dog. Run the water in the casing over the top until it is clear, and you can no longer smell chlorine. Do this by wiring the pump wire back up to the other wire, and turning the power back on.
The pump will pump the water out and onto the ground. This will flush the water through the pressure tank. If you have any filters, screens, or softeners, beware that they may become plugged up by small flakes of rust stirred up by the pump replacement procedure.
Running it over the top a bit longer can go a long way towards prevention, but, is not percent effective. Turn the power off, unwire, reattach the T-handle and chain, lubricate the O-ring s of the pitless with petroleum jelly do not use pipe dopelower down the rest of the way, and reset the pitless. Use the high-powered flashlight to see down the casing to help you.
This step can be very difficult. Make sure to get it right. If you have a horizontal-seating pitless i.

Mass J-Series or similar tap the top of the T-handle to seat the pitless the rest of the way. If you have a vertical-seating pitless Advance or similar and it was on galvanized steel pipe, and was replaced with Sch. Due to the difference in the hanging weight, a pitless of this type may unseat otherwise. Wire the pump back together, carefully stuff the extra wire back in the casing, replace the well cap and tighten the hex nuts to secure it.
Turn the power back on and test your new pump. Normal water service should be restored. In spite of chlorination, it is required in many jurisdictions to submit a water sample for bacteria testing. Treat the water as unsafe for drinking purposes, pending the results of the test. Yes No. Not Helpful 0 Helpful 1.
If the gasket is bad between the pump and the motor, would this cause it to lose suction? I hope you meant the gasket that is the part of the pump. If so, it is worn out and needs replaced. Is wire used on well pumps? And what breaker is needed: 15a or 20a? For a 2-wire pump, solid or braided core submersible pump wire is commonly used, with underground wire run from the house to the well.Well Water Pressure, Pumps & Tanks - How It Works
This may change on deeper wells or higher output pumps, though. Use a 20 amp breaker with the aforementioned wiring setup. Not Helpful 1 Helpful 1. First check to make sure you have power going from the control box to the well. If it is a deep well pump you most certainly have no water if the pump is bad. At the well head you will have to check for continuity with a voltage meter. Not Helpful 3 Helpful 0. Unanswered Questions. How do I shut off the water flow of a well pump?

Get the tank, you know it makes sense. That is a new one on me. Wiki lists four terms as below - must admit have never heard it called "clack valve" either - your backflow preventer at least makes sense in my American English.
The inertia of the meter sometimes spins more than the water you actually use. My use of the term "back flow preventer" comes from my MS Visio with a small rectangle diagram and "BFP" in the center of the box.

We have a problem with low pressure water coming from the mains. That's to say the pressure is mostly ok during the day, but in the evenings the pressure is way too low. I can imagine it's quite a "popular" problem in many parts of the country, along with powerouts, internet connections and all the other things. We live in a very small village out in the burbs. I'm thinking of buying a small water pump to maintain a steady flow, but being a complete novice read: idiot!
Really, it all boils down to just wanting to take the evening shower. We don't need a whole bunch of fancy installations and gadgets all over the place, but just want to keep things as simple as possible.
We're talking about using a pump for around 15 minutes a day, that's all. Checked with the Thai neighbor - they don't have a water pump but use something they call in Thai a "dye naam", which I gather is a 'dynamo', though what it looks like and how it operates is anybody's guess, as the neighbor only makes use of the contraption.
It was apparently already there when he bought the land some years back. Maybe some of you guys know what this thing is.
Here's some info on what we have : Half inch standard Thai water pipe coming in from the mains, to the one-storey house, which also has half inch pipes.
The pipes are all visible i.
