- Q: i want details and requirement of it in water pump
- For the best answers, search on this site https://shorturl.im/awBzE A very good foot valve will cost about $20 then it will be the cost of a service call, here we charge about $70 but depending on where you live, how deep the valve is and where its located the price maybe different, and the cost maybe more on a weekend too. Giving quotes for this is not really profitable for service companies, so if you are not prepared to do it yourself then you will have to pay the service call rate. A good reputable company will arrive at your home and give you an approximation on what it will cost, but remember once you call them there you will probably have to pay the service call rate, if you are running tight on money call around and ask the rates but remember that this is a weekend and most companies will be running a small crew and might take time to answer your call. The other option is since you have changed the pump yourself why not just change the foot valve your self? Have you primed the pump after replacement? To replace the valve the pipe that runs to the bottom of your well must be pulled up and the valve is on the bottom of it, its a simple matter of removing the old one and replacing with new the big job is usally the pulling up of the pipe.
- Q: What's a small soft pipe for a submersible pump in a fish bowl? How do you use it?
- The little air hose is had to pump in pump operation, to play the role of oxygen, generally want to let the oxygen hose head above the water, or to go into the air, and lose the function of oxygen, if the tank is large enough, every day to open the filter pump. Use hose plus oxygen does not matter.
- Q: How can I be sure the water pump is the problem before spending $ on repairs. 97 civic overheating.?
- Simple overheating is rarely the water pump. In most cases water pump failure means either a leak, which is visible as dripping from a weep hole under the car near the timing belt cover, or as a seized shaft, which would mean the engine would quit running immediately and probably be seriously damaged by failure of the timing belt that powers the water pump. Having got past that, consider the conditions of the overheating. If you are losing coolant, start with that. Verify the loss is not because of a head gasket by the simple test: with the engine cold, remove the radiator cap. Start the engine and place the palm of your hand over the radiator neck where the cap came off, and pinch closed the hose to the reservoir. If you feel steadily rising pressure within 3-5 seconds (if the idle is surging, ignore those changes) that is bad news for the head gasket. Otherwise move on. Look for leaks at the end of every hose by feeling with a clean paper towel on your hand, and look for whitish streaks around the top and bottom of the radiator. If coolant is not disappearing, the overheating must occur when in slow traffic or idling, or on the highway, or all the time. If it is when going slow or idling you probably won't see the fan running when it is hot. If it is on the highway, or if it gets hot and stays hot all the time, the radiator is probably plugged with hard water deposits from using tap water to dilute the antifreeze.
- Q: I installed a new water pump on a Cherokee straight-6 engine, the upper radiator hose is not heating up and the engine is starting to make a funny noise. The thermostat is new and was working fine before. The coolant reservoir is full and no more coolant will drain to radiator / engine. Anyone know why waterpump is not circulating coolant?
- Those engines are the worst I have come across to burp the air out of. I finally had to remove the heater hose and back fill the system with a quart squeeze bottle. You will find that a sport tipped water bottle filled with 50/50 mix coolant will get the air out. later I found that if I cut the heater hose in half and installed a flush tee it worked even better, so far it has been the only way I have been able to purge the system. Good Luck
- Q: I Need a water pump, no matter its fountain pump or high stream pump. But the things or you can say the parameters i required in that pump is, 2 inch minimum outlet from where the water come out, pressure 130 or above (in PSI) runs wid a 1 or 2 Horse Powered motor not more then 2HP. And the pressure calculation is flow of the water (130 Psi) , like while water is streaming out.Any one who can sugest some water pumps which can fulfill or near or above to my requirements. thanks alot sir for you kind time.
- With 100M of 'head' you're going to need a constant displacement pump, and high pressure piping. I'd consider an intermediate lift station.
- Q: Plumber quotes installing system using cross-over valve which some way ties the recirculation through the cold water pipes. This sounds like a short-cut. Are there any disadvantages to this system?
- not sure what you are building or designing, city water or well water or truck tanker delivered water, water boiler for heat is common or isolated with shared heat for hot drinking water or there is a separately heated water heater, inexpensive unlimited water or inexpensive gas or oil are all design factors for plumbing. add-on pumps can improve water pressure or shorten the time it takes to get hot water at the tap or shower.
- Q: My house uses a pump that draws well water. With a family of four, I had never had a problem running out of water, even through 4 morning showers. Recently however, I have started running low and sometimes even run dry of water, although it’s now just me and my wife living at home. The pump is only a couple of years old. A couple of neighbors also have wells and pumps, so I don’t believe the water shelf has run low. The holding tank is at least 15 years old and probably older. I don’t know if it has a bladder, but I think it does. It’s a Wel-Trol brand. I’ve checked the pressure with a tire gauge and it holds at 30 psi. Also, it seems the cut in and out switch has a mind of its own. It especially would continue to run, even though the pressure hit cut-off level. Any ideas or suggestions?Thanks
- Could be the pressure switch (cut in and out switch). It is designed to start the pump at a certain low pressure and stop the pump at a desired high pressure. If it is allowing the pump to run past the high pressure limit, it may also not be kicking in the pump at the low pressure.
- Q: I have a Stamas boat that I am in the middle of restoring. It has 2 chevy 350's, with borg warner (sp) tranny's, and v-drives. Anyway, it has standard water pumps to cool the engines, and it had 2 Sherwood pumps to circulate the water to cool the tranny's, and v-drives. First, I am using the boat in Lake Michigan only, the water is very cool year round since it is such a big body of fresh water. I was wondering if there was any recommendation on possibly using 2 electric pumps to circulate the water? If so, what would a good unit be? Second, the transmission coolers were brass, with a honey comb in the center for the ATS fluid to run through, and the water would run on the outside to cool the fluid. Is this a more effective way to cool the fluid than with those expensive brass fitting? Just checking before I spend a few hundred on them to see if a better way to cool my engine and tranny's, in all honestly though, I am more worried about effectiveness than cost.
- You would be playing with fire to use electric pumps to cool the transmissions and v drives. I doubt they would put out the volume of cooling water needed to cool them and have enough extra volume just in case. Besides, the raw water pumps also would cool the engines and exhaust systems if they are raw water cooled or they would cool the anti freeze and exhaust and transmissions with heat exchangers and oil coolers. Those transmission coolers should be plumbed into the raw water system using the same water that flows through the engines. Not to mention the reliability of the electric pumps vs engine driven pumps.
- Q: Hi! I need to find out what kind of water pump I need to buy for an 1978 Swinger RV we just bought to refurbish. I've searched the internet, but nothing seems to tell me what kind I need.
- sarah, okorder and they can help u...but i'm sure sureflo sells the pump u need as its virtually universal. if its the engines water pump then we need to know who made the chassis; dodge or gm. under the hood in the front should be a metal tag saying dodge/fargo or general motors... if its a dodge, the only 2 engine choices for a motorhome are the 360 and the 440. the 360 has the distributor at the back of the motor straight up and the 440 has the distributor in the front of the motor tilting at about a 30* angle towards the pass side. if its a gm, there are 3 motor sizes possible; the 350/400 and the 454. the 350/400 has 4 bolt valve covers and the 454 has 7 bolt valve covers. hope this helps.
- Q: I recently got the water pump replaced on a 99 Oldsmobile Intrigue GL (3.5L V6), and ever since the temperature gage seems to be running higher...between half way and the 3rd line, where before it was replaced it never got above the second line. It is doing this when I slow down and stop at lights. Once I get going the temperature does drop. Is this normal, or did they do something wrong?
- There's a few different things that could be causing your problem. 1: Did they change the thermostat? If so, they may have replaced it with a defective one. If not, then it may need to be replaced. 2: What was the reason the water pump was replaced in the first place? if it was for any other reason than leaking then this could be causing your problem. 3: They might not have gotten all the air out of the system. when you drain all the water and then fill system back up, there are large air pockets in engine that must be bleed out. If not, these air pockets will get trapped behind the thermostat and cause the thermostat not to open when it's suppose to! 4: Are your cooling fans coming on? If not, you may have a bad temp sensor, causing your fans not to come on while you are stopped. This type of problem is hard to narrow with out seeing it in person. I would take it back to the place that replace your water pump and see if they can figure it out.
