Q:Which is the better option for a home water pump? a submersible pump or floor based pump?

In case of pump failure, it's much easier to repair/replace a floor based pump plumbed with isolation valves and unions. I've replaced a few due to motor failures and flood damage. Arguably, the submersible pump wouldn't have suffered damage due to flooding. Another consideration is vertical pump height. A floor based pump has to draw a vacuum to induce water to flow up to the impeller. This limits the practical draw to between 25 and 30 ft. Much more than that height and the vacuum will exceed the vapor pressure of the the water, boiling it rather than pumping it. A special device can be used to boost the lift: an ejector is placed down the well. Water is pumped down to the ejector, which pulls additional water back up using the venturi effect. This method suffers from additional friction losses but has clear advantages. If you need to pump water up a well more than 20 feet vertical, you should consider a submersible pump, particularly if you are concerned about the possibility of the water table lowering.

Q:My car is 3 years old and it only has 18,000 miles on it and I just got it back from the repair shop at the dealership because the water pump broke. They replaced the water pump and something else that was recalled. But I looked online and found water pumps should last a long time. What might have happened to it, and what would cause it to break?

water pumps are cast aluminum normally...maybe there was a weak spot on the pump casting and it failed (but you would of overheated and had a mjor coolant loss that you would of noticed), or maybe the impellor is what internally failed and or the bearing on the shaft.. but yes normally water pumps last for awhile. I usually dont see replacement of water pumps unless doing timing belts and or high milage...but hell annything nowadays since everything seems to be made in China is cheap and poorly built compared to the old days...

Q:im attaching a motor from another filter onto my homemade filter. but i dont want to have to run a cord all the way from the pond to a powerplug. does anyone know of another way to such water into a filter without using electricity? some kind of siphon?

1. I had an electrician put a buried cable in the ground coming up to a weatherproof post with outlets and an on-off switch. It was not as expensive as I thought it would be. 2. You can put the water pump and filters by the house or even inside and run buried water pipes out to the pond, or just put the pump inside and have the filter by the pond which would run by water pressure or gravity. 3. A windmill or solar panel. A siphon uses potential energy stored in the water to work. Once the water has dropped through the siphon, there is no more energy to draw from and the siphon stops. A windmill or solar panel could provide the power to lift the water back up and make the process continuous, or at least while it's windy or sunny. However when pricing these two options even though they would be very cool if you have the large yard to accommodate them, they turn out to cost much more than either 1. or 2. and have much higher maintenance costs associated with them. 4. If it's a very small pond, you can get a solar powered filter/fountain that looks like a floating plastic lily pad. My son had one of these, but it only worked on the sunniest of days, and lasted one summer before wearing out. If you add a large block of filter foam over the intake it may last a little longer. Rinse it out two or three times a week.

Q:I need to replace a water pump on a '95 3100 Pontiac Grand Am and am looking for a guide how to do it. Also, do I need to flush out the coolant or can I just put a pan underneath the water pump and let the coolant pour out when I take the water pump off? Thanks.

never let the coolant pour put a pan under the car to drain it if it is clean you can reuse it if it is not then take it to the city dump they will take it for free some aoutopart stores will take it for free but please don't let it pour or go on the drain that **** is really really bad for the water we dirnk , and for the guide on how to replace it it is really simply use labels and plastic bags with labels to identify the parts , i read this advice before replacing the maniffold on my e 350 and i said **** that im not stupid , guess what i did replaced it and everything but at the end i was missing screws and i had some screws extra that did;t fit anywhere , learn from the advice not from your own experince

Q:I've been hearing a noise from my truck that sounds like a fan blade is rubbing against something metal but I could never figure out what it was and my truck seemed to be running fine. I recently replaced my radiator and now my truck is overheating. Was that noise my water pump going bad and now it's shot?

could very well be.Also could be fan clutch.

Q:no water is running my deep well pump kicks on every 15 min. it runs for 1-2 min when it kicks off then a noise like someone threw a ball against the house. can you help

it sounds like either your pressure switch is messed up or your pressure tank isn't working right

Q:What is a 1 inch water pump?

A pump with a diameter of 1 inches.

Q:my friend has a 2008 Buick Lucerne V8 model. She said its over heating, and steaming from under the hood. the engine is also knocking. Could this be a water pump issue or something else?

What ever it was it has the engine knocking. Its a little too late to wonder now. Sounds like it lost water and then kept running until she ruined the engine.

Q:Assuming that my water pump standard flow is 20m3/h, tolerance value requirements is + 8%, then is not traffic 22m3/h is not qualified?

Tolerance coefficient is due in the manufacturing process, will, so each pump products are possible shapes and sizes do not conform to the pattern of the situation, and ensure the test results in the value (operating point) when compared, should be allowed to have a certain tolerance. It should be noted that these tolerances are only relevant to the actual pump and do not involve test conditions and measurement uncertainties. If the pump at a certain working point (the same lift) standard (Design) flow of 20m3/h, the actual flow of 22m3/h, indicating that the pump in the design process has unreasonable place, resulting in waste of power. Deviations from the manufacturing process usually have no positive deviation.A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.

Q:hi, how long does the water pump last on e65 chassi 745i (miles)

Usually car manufacturers estimate that most car parts (like a water pump) would last the warranty period and this means 40k to 50k miles. Original water pumps from dealers which are installed during car repairs are usually warrantied for 2 years. Of course this can be voided by driver abuse such as overheating the car or low coolant level.
