Q: All water pump have diferent caracteristics, but it is imposible to overcome a certain hight...what is that hight and why?: It depends on the pump characteristics. It has its suction and discharge head limitations.

Q: What is a fair price to have a water pump with belts replaced on a 2006 Chevy Trailblazer?: My 2002 Trailblazer water pump went out. I was able to get a local mechanic to install it (after I bought the parts for $150.00 The fan shroud and clutch have to come off. You need a special tool also. I think the dealer wanted about 700 bucks. I had the guy do it for 150 I bought the water pump (about 40 bucks) and he replaced the serpentine belt since he had to take to old one off.

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: When did the pump start?: The promotion of water is very important to human life and production. There are various ancient water appliances, such as Egypt's chain pump (seventeenth Century BC), China shadoof (seventeenth Century BC), Burton (Eleventh Century BC) and water (first Century ad). The famous spiral rods invented by Archimedes in the third Century BC can lift water to a few meters in a steady and continuous way, and the principle is still used by modern screw pumps.In 200 BC, the ancient Greek fire pump craftsmen invented by Kurt Siby Lucius is a kind of piston pump has the most original, the main components of a typical piston pump piston pump, but only after the steam engine was developed rapidly.1840~1850 years, the United States invented Worthington pump cylinder and steam cylinder opposite, the direct impact of the piston pump, marking the formation of modern piston pumps. Nineteenth Century was the climax of the development of piston pumps, which were already used in a variety of machines, such as water presses. However, with the rapid increase in water demand, from 1920s, the piston pumps with low speed and large flow were gradually replaced by high-speed centrifugal pumps and rotary pumps. But in the field of high pressure and small flow, reciprocating pump still occupies the main position, especially diaphragm pump and plunger pump have their own advantages and are used more and more.

Q: I just move to this house, it's been empty for a while. The water pump keep screeching everytime I turn it on. What can I do to get rid this noise?: Is there water in the system? Pump bearing worn Find a bleed point on the pump and vent any air from it with the pump Off.

Q: What does water flow mean?: The amount of water delivered by the pump during the unit time, that is, the flow of the pump. Generally, there are three kinds of time units, namely, seconds, minutes and hours. In our country, the unit of flow adopts the international metric units, liters, milliliters, cubic, thousand cubic meters, etc., and different units are used according to different usage environments.

Q: We had a thunderstorm followed by power outage last night, this morning I went to use the water and it slowly went dead.I began by inspecting the pressure tank and pressure control switch, then found the outside water pump breaker was tripped, upon resetting the water was back on!But wait, after about 1-2 minutes of use there was a small quot;POPand smoke from the control switch and the breaker tripped again. It seems now that every time the water pump kicks in I've got a 50/50 shot of the circuit breaker blowing. I'm not sure what to do now, I don't want to keep resetting my pump breaker, we really didn't get that much rain so I don't know what would be causing this issue?Any help would be greatly appreciated.Thanks!: If it works on one circuit but not another, why don't you just leave it where it works ? You didn't say what size the breaker is, or if there's something else on the same circuit. Maybe the pump plus one other item on that circuit are together enough to trip the breaker. Is it possible to give it it's own dedicated breaker at a bigger current, say 15 or 20 amps ? There's nothing wrong with being generous with your breaker size, it's not uncommon for breakers to trip if there's a constant current which is near, but under the rated current. It will still trip the breaker if there's a short.

Q: i have a 1996 infiniti i30t and its leaking from underneath the car so i took it in to get it diagnosed and they said i need a new water pump and they are trying to charge me 500 dollers and if i need a new timing belt i have to pay a 1000 dollers. is there a cheaper way i can fix my car. it started to over heat today and this sucks cause its my only car my parents wont buy me a new car so im stuck with this stupid old car and i have to pay for it they wont help me. can someone help me?: The V-6, has timing chains, not a belt. The labor guide shows 3.6 hours to replace the water pump. The retail price on an aftermarket water pump (not genuine Infiniti) is about $60. So the shop's quote of $500 is about right. The only way to save money on this repair is to find a shop with a lower hourly rate. If you've been taking care of the car and changing the oil, you should not need to replace the timing chains. However, it the shop finds that the chains need to be replaced along with the pump, the total bill should be $1,000, not $1,000 plus $500. If they replace the chains, the labor for the pump replacement is already done. Don't pay twice for it.

Q: i am not sure whether the water pump is bad or how much water should come out of exhaust.: It may not be your water pump at all. It could be a blown head gasket or a cracked block. Do you drive it very much? If you do and it doesn't totally overheat, it isn't your water pump. Water pumps usually tend to make a lot of noise when they go bad. Depending on the temperature of the air where you live, I would say don't worry too much about white clouds coming out of your exhaust. You do notice I said white? Condensation in an exhaust pipe is normal. Check the little stuff first. Check your thermostat and radiator cap first. Those are inexpensive. Have your radiator checked at the local Mom and Pop radiator shop where they will also check your hoses and engine oil, to see if it looks like mud. That will tell you if you have a cracked block. Total overheating can be a blown head gasket which is expensive because of labor. The parts cost is minimal, it is just a total b i t c h because you have to get the whole top of the motor off. Have your freeze plugs checked too and if they are plastic, have them replaced with brass ones. It is a very old vehicle and you are going to be looking at some money to fix things. I hope I helped, although you didn't tell me the name of the vehicle. That would help a bit more and if you know it is the water pump, go get a new one!!!!!!! And check your fan belts too while you're at it. Good luck! :) I'm just a dumb lady...lol!

Q: Horizontal pumps, vertical pumps, which kind of expensive?: Not expensive, depending on the specific model, in fact, the vertical pump is not much
