Q: How much should I look for paying for my 1998 Honda Accord Water Pump??? With Labor and Materials?: Your okorder /

Q: I live in a house that uses a pump to push water from a tank to the bathroom and kitchen. It has a sensor that detects if water is flowing and pushes it much harder. Recently, it has been pushing the water for a second or less then it completely stops for a while. It's like a pulse of water then nothing. Can anyone give me feedback on what is wrong here? Thank you.: from okorder :Self-priming pump working principle is: the pump before you start in the pump shell filled with water (or) from the water in the pump housing.Start after high-speed rotating impeller flow to the vortex in the impeller, shell, then the entry form the vacuum, the inlet non-return door open, within the air into the pump suction tube and the impeller, to arrive at the outer edge.Self-priming pump is a self-priming centrifugal pump, it has compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, and have strong self-priming capacity, etc.Line does not need to install the bottom valve, only to ensure storage in pump body before work are quantitative liquid.Pump after the normal starting, impeller liquid of suction chamber and inlet line of air suction, and can completely mixed within the impeller, the function of centrifugal force, and liquid with gas to the vortex flow volume outside edge, the impeller has a certain thickness is formed on the outer edge of the white foam belt and high-speed rotating liquid ring.Gas-liquid mixture into the gas-liquid separation chamber through diffusion tube.At this time, due to the flow rate suddenly drops, lighter gas is separated from the mixture of liquid and gas through the pump body spit continues to rise.After degassing of liquid to liquid storage chamber, and the reflux hole again into the impeller, and impeller with inhalation of gases from the inlet line again mix, flow under the action of the high-speed rotating impeller and the impeller outer edge....As the process cycle, decreasing the air in the suction line, until all gas absorption, complete the self-priming process, pump put into normal operation. What you said phenomenon should be pipeline leak, which leads to the self-priming pump process is repeated.

Q: i have a well that i am trying to pump and i need to have one pump to bring the water up from the well, and one pump to take it out to our lawn. i just wanted to know if i could hook the irrigation pump directly into the well pump, or if that would be damaging to the pump?thanks!: You can always use demand pumps to do the job. This way they just sit idle and wait on the call for water before they go to work.

Q: how to install a main pipe water pump to service the community?: Installation of water pump is very easy, any certified plumber and electrician can install electric water pump. Your question maybe is, how to design water pump water system to service the community? To determine the correct rating of water pump to be used and to design a water system, here are the steps : 1) Determine the safe discharge yield of your well for your water source, by series of tests. This will enable you to know discharge rate of well and the draw back time of water after pumping. This data will be used for designing a pump (its discharge capacity). Note that pump discharge capacity should be lower than well safe yield capacity in order not to drain the well. 2) Determine the suction lift or height of water table in the well by measuring the height from water table up to the top of the well. This data will be used for pump design (its suction lift/height capacity). Pumps suction lift varies depends on its Horsepower capacity and the type of pump (submersibble or centrifugal). 3) Determine number of households in the community. This data will be used for the design of reservoir (tank) for your water system and the number of hours for the pump to operate to fill the tank. Note that the average usage of water is 120 liters per day per capita. So the more the number of population, the bigger the tank and the longer the pumping time in order to meet the per capita usage. 4) Determine the elevations from your water source towards the community to be served. Use survey instrument to determine the elevations. This data will be used to design a height of the tank and the sizes of service pipes towards the community. The higher the difference in elevation from your source towards community, the lower the height of the tank and the smaller the sizes of service pipes. Sizes of service pipes can be determined by hydraulic heads (heights). By following these steps, I gues you can now design and construct a water system.

Q: I replaced the water pump on my 2001 dodge dakota and I still have a leak coming from somewhere. I don't know if i put the bolts in the wrong holes or what. Some bolts were long and some were short. Is there a diagram that shows where which bolts go where?: There are 4 long bolts that go all the way through the pump and and timing cover into the engine block. The rest are shorter but all the same length which seal the pump to the timing cover. You cannot put them in the wrong holes. The 4 long bolts do screw into water passages though. What has probably happened is you neglected to put sealant on the threads of the 4 long bolts that go into the coolant passages. If you put those 4 bolts in without sealant the coolant can weep right past the threads even if the bolts are tight and leak. Remove just those bolts 1 at a time and coat the threads with RTV or gasket sealing compound and re-install them then pressure check the system. Best of Luck!

Q: What is the safety head of a pump? Why should a safety head be added?: The pump achieves this by providing sufficient energy to the liquid at the entrance of the impeller, and ensuring that the liquid remains liquid. This energy is known as the available cavitation margin, referred to as NPSH (A).If there is not enough NPSH (A) or energy, as soon as the liquid enters the impeller, its velocity is increased. According to Pohl's law, the pressure drops. A reduction in pressure will cause some molecules in the liquid to become gaseous, forming vapor bubbles.The performance of the pump will be lowered immediately and the bubbles will continue to grow until the pressure inside the pump causes them to implode.In brief, it is to avoid cavitation.

Q: I just replaced my submersable well water pump, the wire that connects the pump, the d switch, and the water tank. Everything was installed correctly and with the help of a licensed plumber. While the D switch is closed (providing power to the pump) the pump will run for about 5 seconds then shut off for about one minute. It will continue this process until the system attains proper pressure and the D switch will open, shutting off power to the pump. The pump is brand new. Why, when power is being supplied does the pump cut on and off? We have tested the current at the well head and it shows that 230 is being supplied the whole time that the D switch is closed, which is correct.: 12 hours on a civic DX. I am a honda mechanic and I will say that this job only takes 2 hours, 4 hours if your slow and never done it before. Mind you this includes timing belt, water pump, cam seal, crankshaft seal, serpentine belts, valve cover gasket, spark plugs if needed, Honda coolant, and valve adjustment. If you are 1 tooth off on timing your Honda will run, but it will run very rough. Sounds to me like they may have the timing 1 tooth off, 2 teeth off and the car just wont run and if it does it will barely run. This car needs to be taken back and everything i told you should have been done and done properly. What probably happened is the dealer let an apprentice work on the car, since this civic is the easiest to do a timing belt on. However its still their fault that it was not done properly.

Q: I got my oil changed yesterday and took like a 3 hour drive and back home and had no issues.. today I was at my work visiting and I noticed smoke coming from the engine [sort of more of steam] and a lot of smoke coming from the exhaust. The light on the gauge inside the car for the engine temp isn't working but all the other ones are. A mechanic told me it was a bad water pump, but I just want some more opinions. Or if the oil change could of effected that.. My engine coolant wasn't that low but a greenish liquid was really leaking from underneath the car.: water pump ,hoses or freezeout plugs,cracked block

Q: About 2 months ago I started hearing a noise coming from my bathroom that sounded like loud humming every 3 or 4 seconds after I would turn on the water or flush the toilet. I noticed that when this noise happened the water pressure would increase and then it would go back to normal. Then the noise started to get louder. Last night while my husband was taking a shower the water lost pressure and then completely turned off. Now I have no water at all whatsoever except for maybe a few drops when I turn the faucet on. I have a private well and when I bought the house I was told that the well is underneath one of my bedrooms because the house was built on to and they built over the well. I know I can get to the pump from the crawl space. Has anyone had this problem or does anyone know what it might be or maybe even how much it could cost to fix?: Hi. You could have a pressure tank that is in need of replacement or adding air to. The air cushion in the tank has either become compromised or has disappeared completely leaving no air cushion to let the pump build up pressure against. The pump is basically running every time you use even the smallest amount of water and this will basically cause the pump to self destruct. The next thing you may have is a bad pressure switch that is both causing the noise and the pressure variations from the nature of the points being bad. This is not expensive to fix. Under forty bucks. The other fix may run into the several thousands. Sorry. Hope this helps.

Q: We have a 3-story (including ground floor) house. We have 2 bathrooms.We need to invest in a water pump to deliver water from ground floor to all floors + 2 reservoir tanks (one located on first floor, and the second tank located on the second floor).Which water pump do you recommend among these:(1) Valco 261PL or Valco 261PT(2) Davey HS50-05TI'd be MOST grateful if you could kindly advice me on any reliable brand that you know (apart the ones that I mentioned). We're basically looking for a very reliable pump up to around $700 (preferably less).BTW, according to you, what's the typical horsepower we should be looking for? Will 1hp suffice??Thank you very much!: Nobody can accurately answer this question until you give more information. To size a pump, you need to know the flow rate you are trying to acheive (gallons per minute) and the total head (feet) you are trying to acheive. GPM is based off the max flow rate of the fixtures you are using at any given time. Fixtures such as toilets and sinks have typical flow rates. Head is calculated by taking your incoming water pressure (psi) and subtracting pressure losses from pipes and fittings (psi) and working pressure of your furthest fixture. For a small building, like a house, you can probably estimate your head to be the height of your building (incoming water pipe to ceiling of top floor). If that distance is 30 feet, you'll want a pump to acheive 30 feet of head at about 5 gpm. 5 gpm will allow for a shower and a sink to run at the same time. Toilets are low gpm unless you are using flush valves instead of flush tanks. I've never heard of Valco or Davey. In commercial applications, I've always used Bell and Gossett, but that may be overkill. Just make sure the pump you are getting is a pressure booster pump and not another kind of pump.
