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?

I might be miss-understanding your question. If you have no water in the tank then the pump will run all the time because you won't build enough pressure in the system to shut it off. There should be a switch to turn it off manually. If your system has water in it and pump still won't shut off then it could be several different things: 1. Pump is bad and leaking internally... do you have good pressure at the faucet? 2. There should be a pressure cut-out switch somewhere near the pump. This switch should shutoff the pump when the ideal pressure is reached and prevent the pump from over pressurizing the system. Make sure it is not stuck closed. (May have to remove to test) Check for continuity across the terminals with pressure with the pressure on and off. If it doesn't' change... replace. 3. You could have a leak somewhere in the system not allowing the system to build pressure. 4. There may be a pressure relief valve somewhere in the system that is stuck open and dumping your pressure back into the suction side of the pump. Good Luck!

Q:i have a water leak near the water pump in my 1990 cadillac deville i replaced the water pump but it was remanufactured and a pipe on the back of the water pump can it be a heater core or should i buy a brand new one p.s. water leaks after it passes the radiator

it would,nt be the heater core because it,s a good ways from the water pump. it might be that the water pump gasket slipped when you were putting it on or the by-pass hose is bad or loose. check all the hoses like both radiator hoses and where the heater hoses hook up to the block.

Q:I have built my own spray rig to water some stock and tanks and a garden. It is a 330 gallon tank and has a spout at the bottom that i am going to connect a multi purpose pump to. My question is what size pump would i need? I have been looking at Atwoods and Tractor Supply and have seen some 2.1 GPM and a 5 GPM pumps i just don't know which would best suit me. i am planning on having the tank on the trailor and running water hose to a sprinkler or two. I would like to know how man sprinklers are possible on this type of system and still keep good pressure. Thanks for any answers.

Like the last person, what you've looked at won't do much. Just think of a 5 gal bucket and how fast do you want to fill it up. Also you want pressure behind this water if you want to water with it, so look at the psi on a pump as well as the GMP to determine what will work best for you. I'd say 40psi should be enough pressure to run hoses and sprinklers and remember that the smaller the hose at the end gives the highest pressures. Hope this helps you out some. I'll admit, I'm thinking of this as knowledge of water pressures more than GMP, but I think I've explained something good about your question. Good LUCK

Q:What's so good about having a water pump on my stand alone ice maker?What exactly does it do?

I imagine there is also a filtration system on the ice maker so you get clean filtered chilled water on tap instead of buying bottled water or waiting for a filter jug to do its work.Though I find tap water cold enough and tastes ok

Q:guys i have a mini-water pump.....i wanna pump kerosene instead of water,to make a mini stove,on my own..my doubt is ...if the water pump is used to pump kerosene,will the kerosene ignite inside the pump itself or will cause any problem..i just want the pump to pump kerosene....will it ignite inside of the pump,because the pump runs on electricity....can u clear my doubt

Is the motor of the pump built-in so that the pumped fluid flows through the motor also? If the answer to the question is yes then do not use the pump for pumping kerosene. However, if the pumped liquid does not come in contact with motor then you can use the pump for pumping kerosene. But ensure that the pump shaft seal is of mechanical type (so that kerosene does not leak from the shaft sealing area) with parts (specially any rubber parts) compatible with hydrocarbons (use viton rubber parts instead of EPDM)

Q:I will be replacing my timing belt soon. The dealer is suggesting that I also replace the water pump. Is that really necessary? When do water pumps normally go out?

The labor involved in replacing a timing belt will normally cover the installation of a water pump as well. The reason the dealer is recommending the water pump replacement at this time is that the labor involved in changing the timing belt makes it much more cost effective for you to do it at this time. Even though your water pump is working great right now, if you need to replace it in the future, the labor cost will be enormous and close to the cost of replacing your timing belt alone.

Q:i have a 1960 ford f100 and i was wondering if its better to have an electric water pump or mechanical. ive heard mechanical is worse because at low rpms it doesnt put as much water into the motor but i wasnt sure how true that was. What was is better so that my truck doesnt overheat? and how much better is one over the other if electric will just be a little better is it even worth using? also will i need to change anything on my motor to be able to put an electric water pump on it or will it just bolt on like the mechanical one does

Well your mechanical water pump is more than sufficient to pump water through your engine even at low rpms. Whether you have a electric or mechanical your can't pump more water though your engine than what your thermostat will allow you to. The advantage that i can see over electric would be the extra horse power you might get over having your mechanical

Q:1997 Chevy Cavalier, 2.2 engine. In the past 2 days I noticed that my temp gauge was reading a little higher than usual but not in the danger range. I checked and nedded to add coolant. Last night it started making a chattering or maybe klunking sound. As far as I could tell it was coming from the water pump but it stopped before I could get out of the car and look to see. Now the coolant is low again. Are these signs of the water pump being bad or could it be something else?

There could be alot of causes to water lose and slight elevation in temp. If the water pump is leaking most often you will see sings of it at the water pump. Also you may want to check the oil. I know it sounds crazy but see if the oil is a whitish color. You may have a blown head gasket and could be leaking water into the cylinders from the water jackets in the head. Hope that helps. Also check the ground after the car has been sitting and running. If you see water look up from the ground to see if you can locate the leak.

Q:Pump suction and pressure side road why should vacuum table and pressure gauge, and what role they have?

The pump suction and pressure side roads shall be equipped with a vacuum meter and a pressure gauge to monitor the operation of the system. When the pump is running, if the suction side of the vacuum decreases, indicating that the performance of water pump or water absorption pipe leakage; if the vacuum increases, it may be blocked suction pipe. The pressure on the water side is too large. It may be less water or the water pipe is blocked. If the pressure drops, the water consumption may increase or the water pump performance will decrease.The pressure gauges on the water side also play an important role in observing the pressure changes at the start of the pump to determine when to open the outlet valve. Usually larger pump starts, should first close the outlet valve to reduce the starting current, until the pressure of the pump rising and stable, then open the outlet valve.

Q:After I replaced the water pump impeller in my outboard I fired up the motor and now its not pumping any water through the pee-hole at all and also the prop is spinning in the neutral position (motor seems as if it is in gear and trying to move). Would this be because of the shift rod or the drive shaft not being in the proper position and possibly the impeller is being span the wrong in the impeller housing cup?

First the impeller -- did you find all of the old one, or are a couple of vanes missing? When you disassemble to put on a new impeller, you must account for all of the old one -- pieces like to be pushed by water into the cooling passages. I like a thin stiff springy wire to run through the pee-hole and up into toe water pickup tube. If you can blow air through the tubes, they aren't blocked. Did you put the impeller on upside down? It only works one way -- as it spins, the outer ends of the vanes should follow the vane, not lead it. When you reassemble, you must get the gear set aligned properly -- When it's assembled properly, the prop will be locked in forward and reverse but will freewheel in neutral. You must turn the blade so the flat of the clutch dog faces up, with the shifter in neutral, as you assemble it. Try it a couple times, you'll figure it out.
