05 magnum warm engine tapping?
The 2.7 engines kind of have a bad reputation for failure. Usual cause is poor grade oil and maintenance. If your starting to hear a tap or slight knock could be a rod bearing starting to fail due to bad oil or poor grade of oil. It may also be a hydraulic lifter starting to collapse and fail. Your best route would to perform an oil pressure test and maybe switch oil to a full synthetic Chrysler recommends mobile 1. As for the whinning. Your oil pump may be failing causing a drop in oil pressure. Check for oil leaks and metallic shavings in your oil. Only bad thing here is if your already getting noise and clatter no additive or oil will fix it only postpone the problem. If the knocking gets worse take it to a dealership before it gets too late. To help slow the issue and prevent it from getting a lot worse let the vehicle warm to full operating temperature before driving and switch to a full synthetic oil and change it every 2500 miles. But like I said. If its making noise nothing you pour in it will fix the issue it will just help it from getting worse.
My sink faucet sounds like a machine gun when i turn on the hot water what is wrong with it?
Most likely it is the washer on the tap that is loose. They can make a horrendous noise as it gets worse. Shut the water off under the sink and open the tap to drain. Remove the handle and then remove the large nut holding the tap stem in place. Once it is loose the tap stem and turn over exposing a black washer with a small screw threw it. Remove the screw and take off the washer. Go to your hardware store like Home depot or Lowe's and buy a new one Also buy one for the other tap as its not far behind. Replace the washer and put back together just like you took it apart. Hope this helps you and good luck. Richard
Why does the water flow through a hot tap (faucet) slow down as the water warms up?
This was asked before on Yahoo Answers and the asker chose the following as the best answer: "this is caused by a small gasket in your faucet(tap) valve. when the valve is closed the gasket is compresed, when you open the valve, the gasket slowly expands to it's original shape. i dont know if their is anything you can do about this, a new gasket would do the same thing." I disagree as surely this would affect cold taps too. My observation though is that only hot taps slow down in this way and it is always as a result of the initially cold flow of water warming up. This one has bugged me for years, I'd love to have a definitive answer.
Is hot water from the tap safe to drink? I am asking for the countries where tap water is considered safe to drink.
Even where tap water is safe, there are a couple of unforeseen risks to drinking hot water from a tap.To begin with, it is stored in the household water tank for an unknown length of time and at an elevated temperature that is not well controlled. Both situations can be dangerous. The tank water can allow bacteria growth if not hot enough and the flow through can easily allow the same water (warm) to sit for days.The other risk in older construction allowed the use of lead solder in copper pipe joints and warm stagnant water dissolves lead easier than cold running eater. The former could be dangerous while the latter not likely.While not dangerous, hot water is, I believe, pretty well devoid of dissolved oxygen and that probably detracts from the taste.
Why does cold water come out of the sink faucet faster than warm water?
In a typical house, If no one has turned on a tap for an hour or so then the water in your pipes are generally at room temperature. When you first turn on the tap, that is the water you will feel coming out of the tap first. It will feel cool right away since that is colder than your skin and your nerve endings are designed to feel temperature differences, not actual temperature. You will feel that as cold water. It’s just there.. Hot water can only reach the faucet from the water heater, so depending on how far away that is, you have to open the tap and let all the cooler water that is in the pipe between the heater and the tap run out before the hot water reaches you. The colder water, from the underground pipes outside will take time to reach you as well, once the room temperature water that is in the pipes between outside and your taps is drained out. The length of time it takes depends on the length of pipe between those two sources and your taps. If you are at a sink that is close to the hot water tank but far from the intake of water then the hot will reach you before the COLD water reaches you. If your sink is far from the hot water heater but closer to the water intake pipe then you will feel the cold water first.
Why does boiling water sound different from room temperature water when poured on the ground?
The sound of pouring water is complex. Generally, it comes from splashing on different scales, larger splashes (from larger pockets of air or larger drops of water) produce lower tones and smaller ones produce higher tones. Two things are true of hotter water that might be relevant to the sound of pouring: it has a lower viscosity, and a higher vapor pressure.A liquid with a lower viscosity flows more freely, which will create more turbulence when poured and allow the agitated water to continue its violent motion for longer. A lower viscosity is also associated with lower cohesion, meaning the liquid breaks apart into smaller droplets. All of this is a way of saying when you pour hot water it's going to make smaller droplets and air bubbles that, when they collide with each other and other surfaces, will make higher-pitched sounds.The vapor pressure expresses how readily the liquid evaporates. Water near the boiling point will evaporate quite readily. As you expose it to dry air, by pouring, you briefly speed up the evaporation. Very near the boiling point, this may actually make sound, but more likely the presence of large amounts of water vapor in the air simply changes the sound that is being generated from colliding droplets and collapsing bubbles. Sound will propagate through moist air differently than dry air and hot water adds a lot of moisture to the immediately surrounding air.
Why do my water pipes hum like a low pitch fog horn, then the sound goes away when I turn on the water faucet?
I suspect thermal expansion which can cause a faucet or tub/shower valve to open slightly causing the hum. An expansion tank installed in the system preferably near the water heater would likely alleviate the problem(usually a 1 gallon tank will serve an average house0. you could check this by temporarily installing a pressure gunge on a hose bib or laundry connection. {these are available at Amazon, Home Depot and Lowes to name a few} they screw right on to hose threads, once securely installed slowly turn on the faucet it is connected to, assuming no leaks leave the faucet turned on. Then run about 10 gallons of very hot water, preferably in a bathtub. this should cause the water heater to enter the heating cycle. Do not use any water at all and monitor the gauge I suspect somewhere around 100 to 120 psi you will begin to hear your humming, depending on your system. Thermal expansion in time will cause your water heater to fail as well as other issues. If you are mechanically inclined adding the expansion tank yourself is very doable if you follow the directions. Otherwise contact a professional.
