- Q:Do I need to change the water pump if I replace the timing belt ? and does the water pump connect with the timing belt ? if the water pump goes out will it bend the rods ?
- i would get out of that thing they are nothing but trouble always! a have a freind got a nice chevy ,never been happier?
- Q:I have septic tanks. My toilet flushing water is filthy and the water pump runs for a long time and sounds strange. I have turned the pump off for now but know this is not an answer but i was worried it would burn out or something. Do i need a part for the pressure pump? Please help any plumbers out there.
- Oh, groan ...up at 5:30 in the morning with water problems! Well. I guess it makes life 'interesting! ...lol Your well is running dry. - It is what I suspect. - Had the same problem, long ago. First of all ...you don't have septic tank(s). - You have only (1) septic tank. You can't let your water pump run-on like that. - It will overheat and burn out. My water pump was $700.00 dollars! I'm suspecting your water recovery rate in your well is very slow. - Time of year 'possibly'. - Or your well was just not dug deep enough in the first place, to have much reserve water capacity. What looks like dirty water, is probably really actually only sand and silt, that your water pump is sucking up, when your well runs close to dry. There's a free remedy. Squeeze a clamp onto the rubber washing machine water hose. - To restrict the rapid flow of water into your washing machine. If you're watering your garden ...don't water for too long. - Or the well will run dry. I put a water timer on my garden hose, so it only watered my garden for 5 minutes, every half hour. Leaving it that way 'all night' and you'll wake up to a well watered garden in the morning! I'm sure this is your problem, - low water recovery rate in your well - because that would account for the water turning silty. Be ingenuitive ...and it won't cost a penny, or inconvenience. Trini ps. The water that is pumped into your toilet, is well water. The septic tank is where the well water flushes the poo poo to. pps. You're right in turning the water pump off while you wait for the well water to recover!
- Q:1988 fleet wood prowler 22HJust bought it, first time camper owner. I need a battery and a water pump. I only want to buy one, but don't want an overpriced pump. Preferably one I could find at a chain store locally. Can anyone recommend a good one? Also, is there anything I should know before I take my camper to a rv hook up site? I have a pressure regulator that will twist on my spicket on the outside of my camper. Do I need any other kind of regulator, or hose, besides my pump before I go hook up?Can I hookup without a pump? The pipe is capped off where the pump would go. Thanks!
- If you are connected to a campsite water supply you do not need a pump. The pump is only required to deliver water from the fresh water tank of your camper to the faucets and if equipped toilet of your camper when you are not connected to City water, ya I know I have probably been connected to an actual City water supply 4 days in over 10 years of trailer camping... but any campground water supply is referred to as a city supply in the trailer literature. The only accessory I recommend to have is a combination filter which will stop both sediment ( very common in campground water lines ) and secondary charcoal filter which will reduce both taste and chemical intrusions on your system / palate. Would I buy a basic system demand pump? Yes, but if the cost of the pump stands between your camping season and your camping plans for the season, cancel the pump and camp!
- Q:I just put a new water pump in my jeep and after I put it in I ran it and it seemed to have a small leak while it was running it seems like it was coming from the crank which is under the water pump so it might be a leak coming from the bottom of the pump. When I turn the car off it is no longer a leak its more like pouring water out. What do you think it can be? I put a gasket and the blue silicone gasket sealant all around it and on it before I put it in so I have no idea. Thank you for the help.
- The blue silicone has caused a hole in the water pump. Get it fixed now or the blue silicone will leak onto your engine causing more damage.
- Q:What is the influence of the speed of the pump motor on the pump?
- Low speed, the pump has a certain wear and tear
- Q:95 mustang leaking water pump changed the pump and its running backward now
- Belt is routed incorrectly. Do not feel bad as this is actually a common mistake. Another possibility is the Parts Store sold you the wrong pump. This engine (5.0 I assume) was availiable in multiple vehicles and the Mustang was the only one I know of that had some that turned backwards
- Q:Why is water pumping cool water is normal, but when pumping hot water pressure and flow are very small?
- There may be: first, the water temperature is too high, the impeller damage! But this may not be very likely! Second, but also the water temperature is too high, but may be too high water temperature will be hot water pipe deflated, resulting in no water. Third, it is possible to buy fake and shoddy products!!! Another important problem is that you didn't tell me what kind of pump it was! What forms of work do you have?
- Q:i need to know an estimated cost for changing this cars water pumpthanks..
- Too okorder i did this, and by doing so it saved me money, time, and the risk of getting ripped off.
- Q:I have two water well good water but not a lot of water .is it possible to hook two pumps up to one holding tank . if so how do I hook them up
- It should be possible, it would be best if both pumps were identical. They should be hooked up in parallel to increase flow rate.
- Q:House has bad mains pressure, so previous owner installed a quot;Holding Tankwhich stores water from the mains, before pumping it into the house for the internal tanks.However, after some recent plumbing work when the mains was turned off, it's running a little weird. The pump seems to be constantly running, although at a very low level, and some times when the taps/fawcets are opened, they seems to be nothing for up to 30 seconds (only air), and then the water rushes out. Same thing for toilet/WC cisterns..Any advice/pointers appreciated.CheersJM
- If you are using a standard well pump, then there should be a check valve in the pipe between the holding tank and the pump. In a well it will be a foot valve, but may also have been a simple check valve. The work on your mains may have introduced dirt into the valve and prevents if from sealing and maintaining the pressure in the system when the pump stops. Someone also suggested that the pressure tank (not the holding tank) associated with the pump has become water logged. If that is the case then a small volume of water coming out of the pressure tank will cause a large enough pressure change to keep the pump working. Last possibility, there has to be a sensor that determines that the level of the water in the holding tank is low and will turn on the mains supply and when the level gets high enough that the mains supply is turned off. This can be a pressure switch or a mercury switch similar to one with a sump pump, etc. So my suggestions are: Check to make sure that the holding tank is clean and there is no sediment in it. Check to make sure that the holding tank fills when the water level drops, (it appears to stop when it is full). If you do this next procedure, make sure that you know how to prime your pump. I would also turn off the hot water tank. If it is a foot valve, remove the foot valve by removing the clamp and then back wash it to clean out the dirt. If it is an in-line check valve then remove the pipe. between the pump and the holding tank and invert it, and run water through it to clean out any sediment, then replace the pipe. Drain the pressure tank, and if you can pump some air into it. Then make sure that everything is connected, prime the pump and turn it on. Make sure that everything is working, then at each tap, especially the hot water taps, turn them on and leave running until the water flows smoothly. When all of the air is out of the system then turn on the hot water tank.
