- Q: I was just wondering if any body got there valve replaced,and if they are still having symptoms..Such as sweating,and shortness of breath.I do not know if i should see a cardologist, or the surgeon who replaced the valve.Any answers would be appreciated.Thank you.
- Why are you asking serious medical inquiries to idiots like me? it is your existence we are speaking about. in spite of if I had an aorta valve replace the dimensions of time MY discomfort lasted has basically to do with my actual problem, and has NO relevance to you. call YOUR physician N O W!!! it is her duty to charm to close what's threat-free for you, and what can be a symptom of massive aortic valve failure.
- Q: I saw some other answers. I figure the relief valve needs replacing, ok no problem, but exactly how much pressure are we talking about here? what is the correct procedure to shut this thing down to replace the valve?
- Same thing happened to me, but with an oil boiler. Shut off power to water heater. Find the drain valve on bottom of unit, attach hose if it has a fitting. If you have an open sump pump in you basement, just drain into there, or you can fill buckets and keep emptying them. Use a pipe wrench to take of pressure relief valve. Take the valve to a good hardware store, or plumbing supply place so they can match it. Put teflon tape on threads of new valve (thats all i used, no leaks) and install then refill tank, you may have to manually hold down the water feed line. turn on power, and open all faucets to bleed out the air.
- Q: 2003 Ford Focus SE2.0L SPI EngineAutomatic Transmission 145KPerfectly maintained since new!One of the pistons had snapped, yes the actual piston, it didn't mess up the walls, but I am hearing a LOT about these dropping valve seatsI intended to do an entire rebuild with a kit, but did it break BECAUSE of a droppedvalve seat?I don't know because I don't know what that isHelp is appreciated
- highly unlikely , depends how the piston is broken often when revving too high the piston top will separate at a ring groove nothing to do with valve seats
- Q: Hi. I am planning to install new kitchen faucet and noticed that there are two shut off valves under the sink. One of them is badly rusted and needs to be replaced. I noticed that it is connected to three pipes (one of which is kitchen faucet). The other is clearly water coming in. What is the third one connected to wall? Also how should I go about replacing this? Anything that I should be careful of? Thank you.Here's picture of shutoff valve.
- You can install a pullout kitchen sink faucet on a wide variety of sinks. There are many options, but the same is not true for the other type of faucet sprayer: A spout sprayer. Let's say you have a old sink to work with. You're probably going to be able to install a pullout sprayer with little problems. You probably won't be able to do the same with a faucet sprayer built in to the spout on an older sink though. These are excellent when you want to spray and wash your vegetables. When you hold your vegetables under a typical faucet, you have to roll them around with your hands in order to loosen any dirt or other contaminants. The sprayer works like a mini hose and can do that work for you.
- Q: my valve cap is leaking slowing how do i fix it what part do i need
- The cap on the valve is just a dust cap designed to keep dirt out of the valve. To determine if the valve is leaking, move the car until the valve is at the bottom pointing up. Put a little water into the valve and watch for bubbles. Bubbles confirm the valve is leaking. You could try replacing the core with a little valve wrench (you will lose all the air in the process) or go to a service center and have them replace the valve. You cannot replace the valve yourself. If no bubbles, you have a leak in the tire or where the tire joins the wheel. Any tire service center can find and fix the leak.
- Q: I'm drawing a complete diagram of the heart, but I'm unsure of the positions of the different valves. I know there are the pulmoary valve, the aortic valve, tricuspid/right AV, bicuspid/left AV, semilunar valves, mitral...but I know there are several names for some of them, like I think the mitral and the bicuspid are the same...but there are so many sources online I don't know which to believe. If anyone knows for absolute sure the right names and where they are it would be very appreciated if you could help :)
- There are 4 valves on the heart. Right atrium Left ventricle Left atrium Right ventricle. The atriums are the top of the heart...the more smaler ones and the ventricles are th larger ones which are below the atriums.
- Q: So i was looking for car parts and i was using my favorite website, and i was looking at turbos which are wicked costly. But i saw some blow off valves which i have heard about before. But i was wondering if you need a turbo in order to have a blow off valve installed into your car. And if you don't my next question would be is it hard to put one in and how?? Thank you for your time..
- A blowoff valve goes onto your intake or the piping from your turbocharger to make sure that you dont run to much pressure they are adjustable to whatever pressure you desire. Usually people running a positive displacement blower or a turbochargers run them. That being said I'm sure that you could put one on your car but without a power adder it would never blow off. Except in the case of a intake manifold overpressure such as a backfire.
- Q: I have an old trumpet valve stem that will not screw in the valve cap. I ordered a new one but I'm not sure how to remove the old one and put the new one on without doing anything that would influence the look and playing. HELP!!! Professionals are welcome and others. I don't have any professional technicians near by .Summer band is starting up so I need this FAST.
- I hope you have a Bach trumpet, because each valve stem is specific to a particular maker and even to specific models. So, if you don't have a Bach trumpet it is very likely that the stem won't fit. If you cannot remove the valve stem with your hands you can try soaking the joint with oil and/or warm water and dishwasher detergent. You should give yourself a couple of days to see if you can loosen them up. Do not use tools--no screwdrivers, no pliers, no vices, no strap wrenches--if you don't know what you're doing you stand to damage the very fragile valve. You may need to take it to a tech--remember you're trying to avoid a $100+ dollar bill for repairing a damaged valve.
- Q: give some application of varible throttle valve?
- A throttle valve allows continuous control of the rate at which some fluid moves from a region of relatively high pressure into a region of relatively low pressure. An example would be in an automobile engine, where the throttle controls the rate at which air (at or above atmospheric pressure) enters the engine's intake manifold (near vacuum when the throttle is closed.) The throttle in an automobile engine is mechanically linked to the gas pedal (in case you didn't know).
- Q: why is a biological valve replacement weak? in the way it does not last much longer that ten years?why do blood clots form with a mechanical valve replacement?what kind of bleeding problem can the anticoagulant medication cause?if you know the answer to any of these questions (doesnt hav to be all of them) plz answer!! thank you :p
