Q: Hi....my boyfriend is currently waiting to have heart valve replacement surgery and im a little worried about the whole thing...he doesnt like talking about it but if someone knows the answer to my questions I'd be so greatful!!First of all a little detail....he is 19, as far as i know he was born with this problem with his valve but it has got worse over time. he was also born with a hole in his heart but had an operation as a baby to fix this. he gets short of breath and often has pains in his chest. he says hes going to have a pigs heart valve to replace his, by open heart surgery (in a few months time). my main worry is whether the operations are always successful? and will this condition/operation affect his life expectancy??please if there are any experts in the field help put my mind to rest....!thanksshelly x: Open heart surgery is always a risk, as is any major surgery. The main risks are from infection and blood clots. The risks taper off very quickly within a few days after the surgery. Heart valve replacements are a common operation, with a high success rate. Life expectancy is generally better with a valve replacement; but not all valve problems reduce life expectancy to begin with. Sometimes the trade-offs are more of an issue with quality of life, with higher quality achieved with a functioning heart valve, so some people may be taking a medical risk to obtain higher quality of life. No one can tell you for certain what the outcome of this operation will be. The odds are very high that everything will go perfectly and he will fell better than ever before. There is a very small chance that he will end up worse To put the risks in perspective, a person i know had minor surgery to her knee - a simple 1 hour operation done at an outpatient clinic. Ten days later, a clot broke loose and she died in her sleep. I have had the same operation twice and didn't even miss more than a few hours of work. Another person i know had severe heart problems and docs said it was terminal, but an operation could prolong his life maybe 5-7 years. He had the operation and its now been almost 20 years and his cardiologist says his heart is healthy and there's no reason why he might not live another 20 years or more.

Q: Hey,Recently purchased a 2006 Audi A4 2.0T Q S-Line. Loving it so far but i can barley hear the blowoff valve if at all. So i am in the market for the loudest blowoff valve. I realize its a very tiny turbo but id still like to hear it and maybe even turn some heads. If anyone can help me out i would greatly appreciate it. Thank you: The reason for this is because the car has a stock diverter valve in the car. I would not even think about putting a blow off valve inside of this type of car. This is because the car will be running to rich off of the blow off valve. This can cause a malfunction in the computer system in your car. This also will cause a check engine light which will not be able to come off unless you take out the blow off valve and replace it with a diverter valve. A diverter valve takes the air in from the turbo then recycles the air back into the turbo to give it more power. The blow off valve gets the air from the turbo and pushes it out which is why you will get the swoosh noise. There is a type of valve that will allow you to pick what you want whether you want a swoosh noise or to keep the air. You can choose the percentage and I would put in 60% divert and 40% blow off if you really want the swoosh noise.

Q: Where is the illusive heater control valve?: The only valve i could think you are referring too would be the vacuum control on the back of the dash mounted heater controls. They do not have a valve in the coolant lines. The heat turned on or off by a vacuum operated door inside the heater box that merely closes and blocks the heat from escaping into the car. If you are having heater problems first make sure both lines running to the firewall feel hot/warm when engine is at temperature. Secondly you will have to find the actuators under dash on the heater box and make sure they are moving if not ck for vacuum.......

Q: I got new sprinkler valves put in (Rainbird anti-siphon kind). Every time a valve shuts off, it makes a loud squeak, kind of like plastic rubbing (NOT a bang like water hammering). Is this normal and will it go away? If not, what could be the problem? This is annoying because the sound can be heard in the house as it echoes through the pipes.: As the valve shuts down, the diaphragm will vibrate as the pressure changes from one side to the other, then it will Thump as it seals. This is normal. However, to isolate the squeak, you may check to see if there is a 1(backflow preventer installed, 2) (if built into the valves) the variable pressure screw on the top of the valve is set correctly. The variable pressure screw usually has a cross top handle (older ones had a dial) and should be set so that on a high pressure line, it shuts down fairly quickly. If this is open all of the way, it can cause the diaphragm to squeal by slowing the internal pressure change to shut it down.

Q: My car had white smoke coming out from the exhaust.After talking to my mechanic, he said that the valve seat is faulty in which i suspected earlier. He also told that my car need to be overhauled. What would a faulty valve seat cause my engine?: If the valve seats leak it will cause oil to run down the valve stem and either it gets sucked into the intake or it get pushed out the exhaust, depends if both valve stems are leaking. It would be black smoke not white. Your car will produce water in the exhaust system when exhaust goes through the cat converter this may come out as a white smoke but it should not be something you can see if your driving. If it is that much you have a head gasket problem.

Q: the air valve, how does it propel a paintball in a blowback operated paintball gun how does the size/shape/?? of the valve impact how fast the paintball shoots?: The majority of blowback paintball guns use a pin valve, which is opened when struck by the hammer. The hammer is held in the back position, with the spring compressed, by a sear. When the trigger is pulled, the hammer is propelled forward by the spring, into the valve. These sorts of markers generally use a “stacked tube” design, in which the valve and hammer is contained in the lower tube, while the bolt, which is connected to the hammer, is in the upper tube. The gas released by the valve is then simultaneously channeled up to the bolt to fire the paintball, and back to push the hammer back into the ****** position (hence the name “blowback”). Poppet valves are usually easy to replace and require little, if any, maintenance. The downside to this design, however, is its high operating pressure, which leads to a larger recoil and arguably less accuracy. The valve is usually designed to accommodate a specific operating pressure. Low pressure valves provide quieter operation and increased gas efficiency when tuned properly. However, excessively low pressure can decrease gas efficiency as dramatically as excessively high pressure. The volume of gas released by the valve directly affects the paintball's velocity. The velocity adjuster alters the pretension on the hammer spring which controls how long the pin valve is held open for, or more correctly how much gas must be released to push it back into the ****** position. EDIT - Sorry but wouldn't even know where to start on designing a valve.

Q: Ok , I am looking for a valve of some sort that is small (1/4 inch), that has high flow preferably lets all the air out at once.This is for a air cannon type thing. lol: The valve with the biggest opening wins. The type valve with the biggest opening is called a ball valve. It is also the quickest one to open because you only have to turn the valve 90 degrees. Th answer to you problem is, get a BIGGER VALVE and bigger lines. Thmyth bustersrs use 6 valve which are 500 times bigger than 1/4 inch so they are 100 times more powerfull.

Q: do I need a new water heater or can this ne be fixed?: It can be Fixed. Try as Follows 1) tighten it up 2) Put some Silicone around it 3) Buy a new one a replace it. Make sure that you cut the water OFF before you Change anything out. Pop Off Valves are Not Expensive and are Very Easy to Change out. You need a 10 or 12 inch Pipe Wrench and some Pipe Dope. That is all. You unscrew the old one, put Pipe Dope on the Threads of the New one, and Screw the new one in. Takes about Five Minutes and maybe $ 10.00.

Q: How come my boiler supply valve isnt letting water into my boiler, i have a cold water supply hooked up to it with the valve on i have tested the copper pipe goin into it and water flows into it, but when It reaches the valve it stops. I understand that it my have a backflow preventer in it and I am wondering if that could be malfunctioning. The hole you see on the front is where my expansion tank screws in. Also where could I get a new Valve. Thanks.http://img149.imageshack.us/i/boilerfillvalve.jpg/: I work on antique steam boilers and engines for a hobby and if your supply valve isn't letting feedwater into the boiler, I'm going to tell you right now that you potentially have a VERY dangerous situation on your hands. Until you get this issue resolved, I would recommend that you not steam this boiler up under any circumstances, unless you have a backup feedwater delivery system that is working correctly. Many people don't know this, but a low water condition in a boiler under steam is essentially a ticking time bomb and can result in a fatal explosion. As to what may be causing it, I would say it's possibly one of two things: 1.) The check valve has been installed backwards and the flow of water is basically pushing it shut. 2.) The check valve is installed correctly, but is frozen shut due to corrosion and scale. Either way, I would have a certified boiler inspector come out and take a look at it; he can probably tell you more than I can.

Q: I have mitral valve prolapse. Just recently Ive been getting chest pains more often * few times a day* and the panic and anxiety have gotten worse. I had a pain last night that lasted about 10 minutes and it was very uncomfortable.I know mitral valve prolapse is a condition that usually not a threat. But can it get worse over time with some people?My doctor already knows I have it but should I go back to have more tests done?Im kinda scared because my symptoms are getting to be more than what they were.Any advice?: It's not clear whether or not your symptoms are pathological and you are anxious and worrying because you are having symptoms or you are having panic attacks/anxiety episodes and the symptoms you are having are a result of this. It's often a vicious circle, there may be nothing wrong. As you have been told, MVP is a fairly common finding and generally does not cause any problems. MVP is often over-diagnosed, especially in young women- GPs are terrible for this. This happens because some Doctors have incomplete understanding of normal valve anatomy and ECG appearances. Various symptoms are often attributed to MVP, such as atypical chest pain, palpitations, syncope and anxiety. These were sometimes termed mitral valve prolapse syndrome. However, data from the Framingham study and others does not support a link between these symptoms and MVP. Please bear this in mind because some misinformed Drs and Nurses may try to tell you otherwise. The problem only comes with MVP is if one develops severe mitral regurgitation. IF there is severe regurgitation (which I seriously doubt), the most likely symptoms you would experience would be breathessness, dizziness or tiredness. Chest pains (angina) can occur if there is reduced blood flow to the coronary arteries or if not enough blood gets to the thickened ventricle. Best advise here is for you to pop along to your GP so he can do an ECG and possibly an Echo, this is more to set your mind at rest though. In absence of other symptoms, the most likely explanation for your symptoms is musculoskeletal pain.
