Q: i took off the lower unit to fix the gears. im not sure ill be able to put it back on with out knowing how things work in there.so how exactly does the water get pumped. and what does it have to do with the gears, because even though the prop wasn't turning, the water was still pumping.thanks.: did you put the dot of adhesive on the Keyway to hold it from slipping out of place ? Are the pump plates worn around the impeller ? If you just replaced the Impeller and NOT the whole housing, and plates, that is NO GOOD, you must replace the whole unit.

Q: Why does the pump decay when connected in parallel?: When two pumps are connected in parallel, the flow rate is less than two of the rated flow of the pump. That is because of the loss of the pipeline and the incomplete sealing of the one-way valve (backflow) and the maximum capacity limit of the pipeline. The solution is to increase the diameter of the supervisor, check whether the one-way valve is completely sealed, whether the inlet and outlet pipe is blocked or not, and reasonably reduce the elbow and the valve.

Q: Water dispenser in refrigerator has stopped working, how do I replace pump?: Replacing parts in a refrigerator water dispenser is fairly straightforward. If you have to ASK how to do it, you need to ask someone to SHOW you how. As others have stated, there is no actual pump in the refrigerator. Water pressure from the supply line is more than sufficient.

Q: 1.where is it located and what would I have to remove 1st to get to it. And would I need a torque wrench if so what # would it have to be at when re-installing water pump: 4A-FE okorder /... it's an externally mounted pump. so as far as pumps go, it's relatively easy. easy for a novice. knowlegeable begginer should be able to tackle it. here's a clip for water pump replacement on a 94 rolla with the 4A-FE engine. engine bay will be slightly different. but the proccess will be exactly the same. since it is on a rolla, some of the equipment removed for ease of access maybe different on yours. may or may not need or wish to crank engine mounts. youtu.be/BiXCCA5dLM0 use that in conjunction with the manual if needed. to do it right, yes. need a torque wrench. but it can be done w/o one. though since you're asking (denotes lack of experience/no insult), i strongly suggest you rent one and use it. can be rented at most any auto parts store. prolly 20 buck for the day.

Q: I have a deep tropical fish tank, my three in one pump is 15 watts, if I put it in the middle of the active oxygen bubbling tank can function, everything is normal, but not very good filtering, can not clean up the garbage at the bottom of the tank. So they put the pump a little deeper, but at this time the pump does not bubble, the oxygen supply in the pipe there is water, atmospheric pressure can not enter, but still can pump water filter, so that the pump itself harmful? Will the pump burn out? This question is very important to me. Please help my brothers and sisters downstairs. I will thank you for my dear tropical fish: Three in one pump with a hose connected to the oxygen pump as the pipe above the water so that the air will enter the pump, you can spit bubblesYou put it too deep and put the hose into the water too. Without air, you can't spit bubblesIf the pipe is not long enough, you can find a hose for the oxygen pump instead of a long tube, with the hose out of the water and fixed

Q: its a honda accord 1991 Lx my car started overheating only when i stop when i go it doesnt overheat what should i check like the water pump: Pull it out of the car and look at it. But since your water pump is most likely driven by the timing belt, that's a hell of a job. My guess is you probably need your timing belt replaced anyways though.

Q: Water is pumped through a pipe of diameter 13.0 cm from the Colorado River up to Grand Canyon Village, on the rim of the canyon. The river is at 564 m elevation and the village is at 2311 m.(a) At what minimum pressure must the water be pumped to arrive at the village? (in MPa)b) If 4300 m3 are pumped per day, what is the speed of the water in the pipe? (in m/s)(c) What additional pressure is necessary to deliver this flow? Note: You may assume that the free-fall acceleration and the density of air are constant over the given range of elevations.( in kPa)I have tried this over and over but i know B it is 3.75 m/s please help if you know to do this THANKS!!!!!: a) Pressure is the weight of a 1 meter square column of water. The height of the pipe is 2311-564 = 1747 m volume is 1747 m? density of water is density of water at 20C = 0.998 g/cm? = 998 kg/m? mass of water is 1747 m? x 998 kg/m? = 1744000 kg weight of water is 1744000 x 9.8 = 17090000 N Pressure is 17090000 N/m? or 17.09 MP b) Cross sectional are of pipe is A = πr? A = π(.065)? = 0.0133 m? one meter of pipe has a volume of .0133 m? 4300 m? are pumped per day The water in that one meter of pipe has to be changed 4300 / 0133 = 324000 times per day to handle the flow That is 324000 / (24*3600) times per second or 3.75 times per second. Since the section of pipe is is 1 meter, that is 3.75 meters per second.

Q: Trying to replace my water pump and was told labor would cost $90 for an 06 impala 3.9L I don't know if it's reasonable for the amount of work.: That's about an hour labor in some places. Whats the problem. I would have charged you at least an 1.5 hours According to that link above, $125 is the lowest just for labor only.

Q: I have coolant leaking out and i'm pretty sure now that it is the water pump. Question can water pumps leak even if the cars not running?Like a steady drip every two seconds? Forming a decent puddle after awhile, but when running the pump is'nt making any abnormal noises is that normal? Is there other clues to positively know the pump is bad? I cant believe how hard a job it looks like it would be to replace it there is no room! Anybody with some helpful how to's? how about an estimate on how much a shop would charge to do it?: Yes, water pump seals will leak all the time (worse when under pressure). It is not a hard job if you now what your doing. Get a repair manual and make sure you have all the right tools and parts before you start.

Q: i need to know an estimated cost for changing this cars water pumpthanks..: Too okorder i did this, and by doing so it saved me money, time, and the risk of getting ripped off.
