Q:Dangers of mitral valve prolapse?
There are many people with mitral valve prolapse that never have symptoms related to it and never have any problems as a result. Mitral valve prolapse can lead to the backflow of blood through the mitral valve known as mitral regurgitation. This can potentially lead to abnormal heart rhythms, such as atrial fibrillation. The concern with skydiving is that it would lead to a surge of adrenaline resulting in increased heart rate, strength of heart contractions and overall workload of the heart. If you have MVP without regurgitation, then your risk would be similar to the general population. If you have regurgitation it depends on the severity the regurgitation. If you have mild regurgitation, then it also should not be a problem. If you have severe regurgitation, then you could run into problems from the increased workload of the heart. In this case, I would suggest you discuss it with your Cardiologist. It is unlikely that you have atrial fibrillation. If you by chance do, then it depends on how well your heart rate is controlled. If there is any doubt, then ask your Cardiologist. Good luck.
Q:ok i have a heart valve leaking ?
hcd2.bupa.co.uk/fact_sheets/html/heart_valve_disease.html#6 You'll probably have to go into surgery eventually. I would suggest seeing all the doctors you possibly can, now, before it gets worse. Try reading through the website above and see if that doesn't help you a bit.

Q:ford escort pcv valve?
It is actually a pain in the butt, but it is located in the front of the engine, on the drivers side, close to the trans. Follow the larger hose down, and you will find it, wedged between the 2 hoses.
Q:Has anyone ever had Aortic Stenosis Valve Disorder or known anyone who has suffered from the condition and
The aortic valves and mitral valves are 2 separate valves. The aortic is the valve that leads to the pipe supplying the body and the mitral valve supplies blood from left atrium to left ventricle. Both can become thickened, making it difficult for blood to get through. You normally will have annual or bi-annual assessment of the valve using an echo and only if it is severe or causing symptoms would surgery be considered. A valvuloplasty involves inflating a balloon to split the mitral valve - this is usually performed in patients who have previously had rheumatic fever as a child and whose valve is fused at the edges symmetrically. In exterme cases a valve replacement can be performed where a mechanical or tissue valve replaces the diseased valve.
Q:How many types of safety valve (relief valve)?
The four common types of pressure relief are the spring loaded valve, the rupture disc, the balance bellows spring loaded valve and the pilot operated relief valve.

Q:replacing a faucet, but i have a broken hot water valve?
There should be a main shutoff valve to cut the entire water supply to the house. If you have a basement the main valve would be where the water supply comes into the house. 99% of the time that is in the front of the house. If you live in a slab house then the main water shutoff is usually near the hot water tank in a pipe that typically comes out of the floor. If it is not there then it will be in the yard (usually the front yard) undeneath a metal cover. You can always turn a valve off and then check water by opening a faucet. Remember that you need to give it a couple minutes to see if it has shut off fully as water may drain out of house pipes. If you are just going to replace the hot water valve then you may have a shutoff for that above the hot water tank. Most lilkely the inlet side but could be the outlet side or even both. You can try those. Now you replace the valve once you are sure that water is shut off. You may not need to drain the hot water tank. Just turn it off and see if water continues to come out. Just turn a valve off and check to see if the water shuts off. Eventually you will find the right valve. Just remember it can take a while for water to drain out of the pipes. If you need help replacing the valve just add an additional comment and I will check back. Describe to me whether you have copper pipes or galvanized pipes and the type of shutoff that is there now.
Q:What do people mean when they say they have a 12 in valve?
A 12 inch valve means it is designed to fit with nominal 12 inch pipe. Most 12 valves are flanged so these valves would also be flanged to match as 12 piping flange. They would also be sized to match the appropriate flange rating as in 125#, 250#, 150#, 300# 600# and so on. As to the opening of the valve that will vary depending on the type of valve. For a gate valve it will be very close to 12 inch in diameter. For a globe valve it may be a bit smaller. In some cases you will see what it called a reduced port valve where in internal opening is smaller. This is more common with large ball valve where the smaller ball and opening makes the opening/closing torque less. These valves also tend to have a venturi shape on the inlet and out leading to be ball so the pressure drop is closer to a full opening valve.
Q:Replacing Valve Cover Gaskets?
The valve cover gasket (parts and labor) is about $100 - $200 for the left side and $300 - $400 for the right hand side, but be sure you didn't misunderstand and the failing gasket is actually a head gasket. Those are a big deal: $1500 - $2000.
