Q:well water pumps and systems?
ANY extra info is a plus. Well size and construction, depth, water level, production test results, and pumping apparatus, all help in troubleshooting problems. The two most likely things I can think of that would make your water pressure act the way it does are as follows. My first guess is that your pump is capable of pumping more water than the well will produce, thus drawing the level of water in the well down to a point where the pump catches some air and quits pumping. The pump continues to turn and when enough water comes into the well to cover the pump, it's starts to pump water again. Second guess is that you have a thermal overload tripping and when enough time goes by, it resets and turns the pump on again. Overloads often trip when you have a low voltage situation at the motor. You can get low voltage form bad connections @ splices or the contacts of the pressure switch. Most well water systems go a long time between maintenence calls, especially at first when EVERYTHING is new. My advise would be to call the contractor that drilled the well and installed the pumping equipment. Hopefully they are one and the same. The contractor knows the original conditions and all equipment used, even the stuff you can't see. Because the system is relatively new, the original contractor MAY be inclined to cut you a deal on repairs. We don't know how long this problem has existed, but perhaps the system really wasn't up to par right from the start. Good luck. When you talk to the contractor, try not to sound to accusatory. He may have done his best with the geologic and economic set of conditions he was given. Nobody can make gold out of lead.
You should have a pressure tank or bladder tank (same thing) in the plumbing after the pump. If you do have a pressure tank it could be waterlogged.. most all tanks in the last 20 years have been bladder type tanks. the bladder may have leaked inside and filled the tank with water leaving no room for expansion. it should have a valve on the top of it like a valve stem on a tire. Check the pressure on it with the pump off. it should be about 4 pounds more than your pump cut on pressure. Or you could have a bad pressure switch. There are LOTS of kinds of pressure switches, so I won't even try to tell you how to check it. but the pump should run till the pressure is built up in the tank then sut off and not come back on again till the pressure on the lines is lowered to the cut in pressure on the pressure switch.without more specific information or a pic I can't help much more. First thought is pressure tank needs checked or replaced. Good luck.
Q:my water fountain pump is not working !?
This Site Might Help You. RE: my water fountain pump is not working !? i used my water fountain pump for the first time yesterday and I've had it for 10 years and i used it yesterday it worked with the water and everything was fine! then the next day i wanted to turn it on , it went on it started vibrating but it wasn't pumping when i had it on the other...
Q:What is the difference between a low pressure pump and a high pressure pump?
The magnitude of the pressure at the outlet side of the pump
Q:should I buy a used water pump with under 1000 miles?
buy a rebuilt 1 from auto zone or advance. better yet get a lifetime pump. buying off someone, you cant believe them.
Q:98 Toyota Camry water pump replacement?
water pump is driven by timing belt. need to replace together. water pump may have threw belt off, explaining no acceleration. weekend job, use new pump, vs. reman. get set with belt and new tensioner.
Q:Possible House Water Pump Problem?
I would still be leaning towards alignment issues are at play here. What I would recommend is putting it on a dyno, not to check the power but so you can see what is happening while the engine is under a power load. I did build an engine once that could not keep belts on, they spun off. I have seen some truly strange things happen. Perhaps the strangest was a thrust bearing allowed to much crank shaft end play and as a result the starter was binding on the flywheel. Yet another was a cam shaft retainer not installed properly allowed the timing chain to snap. Another possibility is the crank damper pulley and not being seated properly.
Q:how to check water pump?
you can leave the radiator cap off and see if it circulates or you can pull 1 of the heater hoses off and see if anti-freeze is coming out.
Q:Is it my water pump? Help?
Nicky, There are usually only two reasons to change a water pump and it's easy to check both of them. #1. With the car on ramps or jack-stands crawl underneath and look at the water-pump weep hole on the bottom of the input shaft casting. If coolant is leaking out the hole the pump needs replacing. Coolant will leave a perfect track from the weep hole the same color as the antifreeze. #2. Remove the serpentine belt and spin the water-pump by hand. If it spins with no noise or a lumpy bearing feeling in your fingers the water-pump is fine! While the belt is off, spin all the accessory pulleys to hear and feel if there are any bad bearings.
Q:how to replace water pump 97 pontiac bonneville?
It depends on which engine you have, with or without a supercharger. The non-supercharged engine is a piece of cake. the supercharged one is a bit of a pain to get at the water pump. On the non-supercharged engine, all you need to do is remove the serpentine belt, the water pump pulley and the bolts that hold the water pump to the front cover. I have detailed instructions if you send me your email address I can give them to you. They are from GM Service Information website. I can't give you the link to the website because I have to enter a password to enter the site through work.
