Installation of water pump is very easy, any certified plumber and electrician can install electric water pump. Your question maybe is, how to design water pump water system to service the community? To determine the correct rating of water pump to be used and to design a water system, here are the steps : 1) Determine the safe discharge yield of your well for your water source, by series of tests. This will enable you to know discharge rate of well and the draw back time of water after pumping. This data will be used for designing a pump (its discharge capacity). Note that pump discharge capacity should be lower than well safe yield capacity in order not to drain the well. 2) Determine the suction lift or height of water table in the well by measuring the height from water table up to the top of the well. This data will be used for pump design (its suction lift/height capacity). Pumps suction lift varies depends on its Horsepower capacity and the type of pump (submersibble or centrifugal). 3) Determine number of households in the community. This data will be used for the design of reservoir (tank) for your water system and the number of hours for the pump to operate to fill the tank. Note that the average usage of water is 120 liters per day per capita. So the more the number of population, the bigger the tank and the longer the pumping time in order to meet the per capita usage. 4) Determine the elevations from your water source towards the community to be served. Use survey instrument to determine the elevations. This data will be used to design a height of the tank and the sizes of service pipes towards the community. The higher the difference in elevation from your source towards community, the lower the height of the tank and the smaller the sizes of service pipes. Sizes of service pipes can be determined by hydraulic heads (heights). By following these steps, I gues you can now design and construct a water system.

I must change the timing belt of my car. I have been told that the water pump must be done too since it is right there. Due to the high price I want to postpone/skip the water pump until the next tune up. What happens if the water pump fails down the road? How long does a water pump last? 120K? My car has 60,000 miles on it. Thank you.

There is no guarantee on how long the water pump will last, but normally 100,000 miles plus. But that is true of a timing belt too. The water pump has a weep hole at the bottom, visually check for corrosion or rust in that area. If you see some, could be a sign that it is ready to go soon. If not, then do the repairs that you can afford. But why the heck are you changing a timing belt at 60,000 miles.

The submersible, intermittent pump for my household water well, which is undergound out in the yard, “bangs” when it starts and stops, and vibrates the pipes when it runs. Any idea what might be causing this, or how to make it stop doing this? This all started about 5 months ago and has been getting worse.

It sounds to me like water hammer. There are a few ways to address it, probably the easiest is to add an expansion tank. To find out, try connecting a garden hose somewhere in the system, preferably a cold water pipe. Drain all the water from the hose and put a nozzle or plug on the end so the air can't escape, then turn the valve on. The air in the hose will act as a cushion and, if water hammer is the problem, you won't hear it while the hose is connected. That is not a permanent solution, just a simple test that might give you an answer. Good luck

I have had this water pump changed 2 times in 5 years is this normal for this car? It has a v6 motor.

1. Remove any radiator shroud, or any cowl obstructing the fan, radiator, and water pump. 2. using a pair of large pliers, take off the clamp on the lower radiator hose at the water pump and drain the coolant into a container. Make sure the motor is COLD, room temp, when you do this. 3. Remove the other hose. 4. Remove the cooling fan using an air hammer or a large adjustable wrench. This part is tricky, unless your fan is bolted on with 10 mm bolts, then you lucked out. 5. For step 4, leave the belt on, it will make it easier to remove the fan. 6. If you have a V-8 LT-1, then you have 4 13 mm bolts. Be careful not to damage your distributor which sits under the pump (nice design GM) 7. Using a razor blade, remove any gasket on the inlet and outlet on the block. 8. Apply a thin layer of gasket sealer on the gaskets for the new pump. 9. Install the pump, and its bolts. Use locktite if you have some on the bolts, medium strength. Tighten the bolts to about 90 in/lbs 10. install the pully, and fan. (again, tricky) 11. Install the belt. 12. put lower radiator hose back on (leave off upper) 13. pour 1/2 a bottle of Dex-cool coolant in the radiator 14. fill bottle up with 1/2 water, 1/2 coolant, and pour it into the reservoir. 15. If necessary, get new bottle of coolant, and pour it into the UPPER RADIATOR HOSE, this will help bleed air out of the system. 16. keep filling upper hose, and radiator until it stops bubbling down and basically overflows. 17. install upper hose. 18. make sure the radiator is full and system has no air pockets. Check to see if the upper radiator hose inlet has a bleeder valve. If it does, use a pair of pliers and open it, and watch coolant in radiator drop, then fillit up again. The V-6 has one, not sure about V-8. 19. put radiator cap on, and resevoir cap. 20. run motor, check for any leaks. 21. drive, if vehicle is overheating and there are no leaks, there is still air in the system. Wait till it cools down and bleed air again.

Fire pump and spray pump requires a preparation, 2 sets of the same pump requires mutual investment, when the main pump failure of backup pump automatically put into use. 1: so what is the throwing device: 2: where is the device installed? It should be in the water pump control box. 3: what is the principle of mutual voting? Detailed description

The main purpose of the control is to make sure that the pump outlet has a nominal pressure.Control requirement: 1. Start single pump manually.2, two pumps should alternate.3, the pump exports to achieve certain pressure, the normal operation of the motor, and the pressure is too low, the operation is meaningless.Device: AC contactor, intermediate relay, etc..Principle: 1, detect a pump fault (usually take the motor main contactor, auxiliary contact), interlock another pump to start.2, pump outlet pressure detection device detects low pressure, can start another pump at the same time, to ensure the normal export pressure!

I've noticed after driving my car for a while recently it squeals while accelerating. I'm wondering if its the water pump cause I've had a coolant leak for a while. I poured alluminum sealer in the reservoir and its stopped the leak almost completely though. If it was a broken pump, would this sealer have stopped the leak like it has? I drive a 2000 saturn sl2

it could be, the sealer causes more problems than they fix. you will need to clean your cooling system,heater core and radiator and all your hoses.

my water pump has gone south on me and I want to repair it myself any ideas on how to will be greatly appreciated, do to space between the water pump of the engine and the chasi or body of the van that makes working on thi vehicle kind of difficult any knoledgeable instruction will be welcome. thanks for the help. I am in California,the name is Elmer

2000 3.3L engine. I understand,depending on engine year, it can be a very difficult job. Is this the one or is it much more difficult on the 3.0 L ? One involves timing belt ? Help ? Thanks' Ken

This okorder /... Look on the front of the engine and see if it is there with a pulley and normal belt on it.
