- Q:i have well water. suddenly i'm getting more pressure in my water. I have a well siofterner system. does anyone know what could be causing more pressure to come out from the water?/ thanks alot.
- too much pressure in your pressure tank bleed some air out. reset pressure.
- Q:The diving pump in the aquarium stops and stops on the goldfish
- The submersible pump has been on all the time.
- Q:I have a Goulds JPlus water pump inside my home. Last night, my wife and I heard it going on and off repeatedly when we went to bed. I have two shallow wells hooked up to it, so I switched wells even though I didn't believe the one I was on was dry (it was supplying H2O fine).Still no luck, so I turned it off at the breaker and shut off the valve between the tank and pressure switch. Today, the pump pressure gets to between 50 and 60, then goes off. It then loses pressure v ery quickly (approx 10-20 seconds) and goes back on when the pump switch hits the lower threshold. It sounds like the water is running back through the pump and out of the house when it goes off unless I turn the shut off valve I spoke of earlier. I changed the pressure switch and no difference.I can, however, turn it on and shower, flush, etc. I just then have to go down and turn the pump back off.Any help would be greatly appreciated!
- Tommy is correct in saying that a proper air bubble in the top of the water storage tank is needed to provide a slowly declining pressure on the system as water is withdrawn. But if no water is being withdrawn inside the house then a check valve preventing a backflow through the pump discharge and allowing loss of water in the pipelines to the individual wells is leaking. It needs to be replaced.
- Q:how do u know when u need to replace ur water pump or how do u know when its not working??? thanks
- i like the way you said that.h2o pump.well if the water pump isnt working like it should,then it will overheat and the temp.light will come on and also if its leaking anti-freexe,its time to change it.also if the bearing is making a racket,it is time for a new 1.
- Q:The pump works and water goes to the house from the reserve tanks but there can be long delays before it cuts in after mains pressure is lost. After it stops the pressure gauge falls back slowly to zero. Pressure vessel is a sphere has a valve on top. Any suggestions ?

- Q:When my wife was driving on freeway, the alternator belt broke and battery sign showed up. She also told that the temperature gauze showed high. Luckily she reached home with the battery fully charged. When I checked under hood, there was coolant spill surrounding water pump . I could not figure out where the coolant came from. Overnight parking did not show any further leakage of coolant. is there a need to change the water pump also.
- Depends. On older vehicles they used multiple drive belts for the different components (my '88 Caprice had 3 belts), but most newer vehicles only use 1 belt called a serpentine belt which drives multiple components (my '00 Dodge Ram 1500) If you lose your serpentine belt it will set the battery light as the alternator is not outputting the correct system voltage, and since the same belt drives the water pump then yes the car will overheat. It's dangerous to keep driving like that, most newer cars have aluminum heads which will warp when they get tooooo hot = expensive repair
- Q:i have a 2003 dodge neon and my thermostat keeps rising to the highes level setting off the indicator (its not broken) i did have a leak in the raiditor and it was very notice able..after pacthing is up there was noproblem till yesterday now the thermostat keeps rising i admit the is very little antifreeze in ther and the rest is water but the is the same mixture tha was in the care that it was rinning off for the last three minths i cannot seem to keep the thermostat down my raiditor is in nee of repair but i m wondering if its the water pump does the water pum help regulate engine temperture? ther are no ivsible leaks and no drippiage could it be that i just need to put antifreeze or could it be the water pump or a broken raidiator? help i will give points for best anwser but really i just need help!
- Codes won't tell you anything and there's no such thing as a thermostat fuse. this can be several things, but it's not likely the water pump. what fails on a water pump is the bearings, a failure that would cause this type of problem would be a frozen water pump and if that were the case, the belt would squeal like crazy and break, as it move but the w/p didn't. a bad w/p will drip coolant from the bottom just back of the pulley, there is a hole there that leaks when the bearings are bad,, but that won't cause a overheat. If the coolant is low, top it off, with the car cold into the rad and the overflow bottle. Change the thermostat, it could be frozen shut, but it is unlikely. if you rad is that shot, you could change it, but the most common cause of this sort of problem is a warped head and/or a blown head gasket. A mechanic can check for this, but take it ot one you trust, as this is about a 1,500 dollar job either way, you have to pull the head to fix it. Running it with low coolant, unfortunately can cause this. if it's not this than the rad is plugged up, but if it just started happening, and it temp gauge maxes out all of a sudden with a full coolant tank, it is likely the head gasket/head. It can also be a cracked block. Sorry to be the one to give you the news..
- Q:Can I use Ultra Blue gasket maker on a water pump? The packaging is not labeled high heat.
- i could replace the gasket now particularly of attempting to recollect on end leak. reckoning on the place you reside, it somewhat is gonna get chilly authentic quickly. Wrenching in chilly climate sucks. And if the unique water pump has by no skill been replaced, you're able to think of approximately doing that while you have it aside, no count if it is not too costly for a clean/rebuilt pump. i be responsive to it could be in simple terms my success to take all of it aside, replace the gaskets, then have the water pump crap out 2 months later. DOH!
- Q:So my daughter's car is an 02 Accord manual with about 127k miles. It's making a squeaky noise which apparently is the belts. The dealer says they're too tight, but are in okay condition. They want to change the water pump and adjust the belts for $750. This seems a bit steep to me. Does the water pump need to be changed if it's working properly? How much should it cost to adjust the belts? I'm thinking she should find a more reasonable shop. What are your thoughts?
- Have them do it, that's a fair price and required service. This is a complicated job because there's also a balance belt to do along with the timing belt, also a special tool required to lock things in place during the job. A water pump and new coolant is valid during this as it is so hard to get at otherwise. Do it there, the dealer is best for this or my shop but you're probably a million miles away. :-)
- Q:ive just replaced my water pump as i know it wasnt in good shape and was a big cause of my problems. but the new water pump also seems to make a noise once in a while like its dry and there isnt anywater or its having a hard time. the head is good and has an extra thick headgasket on it. my guess is i have a clogged radiator and it would sound reasonable as i have used head gasked sealant in the radiator and it has prob clogged parts of it. the other symptom is afater about 4 hrs of continuous driving it starts to over heat if im doing 70 bor more but if i drop back down to 65 it seems to stable out or in many cases go down all together. anyone else had thes symptoms. and will a water pump make noise if there isnt anywater to pump.
- what is the 22r fitted in as most run a thermo fan assy which is fitted to the front of the water pump if you have this then most likely the thermo is either just about to seize or it's still turn's then its in freewheel mode the best way to check is when the motor is cold check and se if you have a thermo fan fitted if so out one blade at 12 oclock and spin with one hand if the blade goes down past 3 oclock then you will need to open the coupling this is a simple job you will see 8 phillips head screws remove all and crack open the coupling but before this is done go to your local toyota dealer and purchase 1x 08816 10001 silicone empty this into the coupling and close this will fix your problem
