Q:Even when all water is shut off in the camper, my water pump keeps running. Even when the tank is completely empty. Does anyone know what is causing this?: The pump is pressure regulated and kicks on when pressure in the water storage tank drops, such as it does when you open a water faucet. Either the pressure regulator is defective or you have a leak in the plumbing. Somewhere there is an electric switch where you can turn the pump off manually, either on the pump or near the pump. I suggest you shut it off until you can determine what the problem is.

Q:How do you measure and analyse the pump characteristics and efficiency?: you can ask the question to a motor company

Q:A mechanic replaced my timing and other belts on my 2001 Mitsubishi Galant 4 cylinder today but not water pump. He said the water pump looked good. All the other mechanics I talked to told me they had to replace the water pump. This mechanic said the belts were not connected to the water pump in this car and therefore the water pump was ok. The car has about 100500 miles on it. Is this bad or should I call him back and ask him why he didn't change the water pump. I don't want to pay more later.: Replacing a water pump may or may not be correct, if it's not leaking or noisy then it is still serviceable. The issue is more of a preventative maintenance issue. It will likely fail, and when it does, you must remove all the parts involved with the timing belt job to access it, so you incur the labor cost twice. I recommend a water pump be done at the second Timing belt or around 120K miles, if not done sooner. also the tensioner pulley/s at that time as a safety practice, some engines use hydraulic tensioners that are prone to failure (early mitsu's). There is no way of saying how long the water pump will last, and when it does fail, it's usually an inconvenience.

Q:my pump went out and i can't afford to have it fixed at a shop.: then buy a new one and get your self some tools and a repair manual at autoparts store not much to it once you see what it looks like you start removing parts that are in way til you can take it off clean the old gasket off well and but some blue selicone put on new gasket and put on new pump tighten it put back on all the parts you remove fill radiator start check for leaks should be able to do it on the weekend about three to four hours or lless... any of these will help all about the same as the other but it will give you a better ideal of how to do it and your sure to learn more about your car so doing it would be best not only you learn but you save money too... not hard to replace most parts hard part is knowing what is wrong to replace it so you got the hard part done knowing what is wrong

Q:Today I was installing a new water pump on my 1999 grand Prix. When tightening the bolts one of them snapped off. Now the pump leaks from that broken bolt. I was wondering if I would be able to stop the leak using some sort of sealant or would I have to take the car in to get the bolt removed?: Putting sealant on it might stop it from leaking for a while, but that's not a good fix. If you seal it up and it doesn't work, it could end up being a huge repair. In addition, what if a temp fix leaks profusely at the worse time. The best thing is to take it apart and fix it right.

Q:What does water flow mean?: Forehead... Flow do not understand it....

Q:Does it take more power to pump water with a 1 /12 hp bg motor/pump than one that is a spare pump/motor running dry,not connected to the system? I am trying to figure out how long it will run with an power inverter during a power failure.: Your Bell and Gosset pump runs on 110 volts and circulates the water through the heating system. It will not run dry because the motor is seperate and spinning an impeller.I don't understand what you are trying to accomplish.

Q:How do I check my well water pumping system to see if there is a leak? I have terrible rusty water.: the only way to check it is to have a well pump service pull the pump and check the verticle lines. they tend to rust out. you can have them replaced by pvc lines now. when our pump went out we had all of the lines replaced because several of the galvanized lines had pin holes in them

Q:My friend wants to buy a 90's somethin dodge avenger.( not sure what year) and the guy says the water pump is bad. Does the car have to be re timed when u replace the water pump?: There is no connection between the water pump and the timing. Timing is a function of the engine ignition system, water pumps are part of the cooling system. There is no relationship. The water pump is driven by the belt that drives all the other engine accessories. Changing a water pump does not in any way effect timing.

Q:It is used in a water pumping station.: It a waterproof pump that go underwater without shorting out. It uses an impeller to move the water. Some impellers look like a star and some look like the Impeller on a car water pump. There different designs depending on the amount of water the pump will pump.
