Q:I have a 78 honda hawkii 400 or cb400TII and I need to know what the valve gaping needs to be set to: Try okorder or usually free down loads.

Q:My sump pump shut-off valve is very noisey. I wrapped insulation around it, but it still clunks. The clunk can keep me awake.: Silent Sump Pump

Q:How much will it cost to fix 5 broken gas valves out of 6 from my truck it's a Chevy s10 99'I live in North Carolina: ...Gas Valves???....WTF....

Q:What are the requirements for valve automation?: Some valves are controlled to maintain a fixed pressure on a system. Others control the level in a tank or vessel while still others actually control the flow rate in a pipe or line. The automatic control of flow through a valve requires a sensor to determine if flow is needed or what the flow rate is. You then need a controller to take this input and then adjust the valve to achieve the desired result. This is called a control loop. Some are all electric/electronic while others are all pneumatic. The valve itself is a specific valve designed to perform the function intended. It is not a good idea to take an existing on/off valve like a gate valve and try to control flow. These type of valves do not have a flow characteristic that is proportion to valve opening while a control valve does.

Q:Ball valves are much more reliable. Also, if you have the gate valve for the main shutoff, is it against code to put a ball valve right after it, so you have a working shutoff when the gate valve fails?: I agree with Ed. I have had far more problems with gate valves than ball valves. They can break in either the on or off position which can really be inconvenient. They usually break on me in the off position after performing minor plumbing repairs.I will often use the main shut off at the street if I see an old gate valve. If you are required to use a gate by local codes (I don't know your codes but here in California a ball valve is fine) put the ball valve after it and use it for your shut off.

Q:A reading from my 2002 ford explorer said insufficient flow from the EGR valve. Would it be possible to clean the valve or fix it or would I need to buy a whole new valve?: I have replaced several DPFE's for this reason. Never had to replace an EGR valve for the insufficient flow code. Like previously posted best to get a genuine Ford DPFE

Q:So I tried to go skydiving last weekend and they told me know because I have mitral valve prolapse. I've had it for years and it's never really been a problem for me, I just have chest pains sometimes and feel palpitations. What would be the danger of not telling the skydiving place about my problem the next time I go in? I know I should tell them, but I want to skydive. What could happen to me if I jump? No lectures about what's right and wrong here please. I just want to know what's the worse that could happen?: 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:Is it hereditary? My dad had a bicuspid valve and we got told it was hereditary but some doctors say it's not, my parents wanted to get me tested in case i had it so we would know in advance but the doctors here refuse to do it (I live in England if that makes a difference) my dad said he would pay to go private if it's hereditary. I know someone who had a bicuspid valve and 3 out of her 4 children inherited it, i know it's pretty harmless until i reach an older age but my parents and i would like to know now, i'm 13 by the way.=]: About 1-2% of the population have bicuspid aortic valves, although the condition is nearly twice as common in males. It is more common than any other congenital cardiac anomaly. Bicuspid aortic valve has been found to be an inheritable condition, with a demonstrated association with Notch 1. Familial clustering as well as isolated valve defects have been documented. The incidence of bicuspid aortic valve can be as high as 10% in families affected with the valve problem. Other congental heart defects are associated with bicuspid aortic valve at various frequencies.(Wikipedia) The cause of this problem is unclear, but it is the most common congenital heart disease. It often runs in families.(MedlinePlus)

Q:i need exhaust valves material dimensinons of any car.: Most valves are made of forged steel. The dimensions depend on what car. You can get a factory manual for any car. Call a motor shop to order them. Don't try to make them yourself.

Q:I am being sent for a level 2 Ultrasound Thursday because my previous US showed one of the babies valves was enlarged. She said all 4 chambers were there but she was very vague on what this means. Care to shed some light?: ?UPDATE? We went to the US today and the heart was 100% HEALTHY!! There was nothing wrong with any anatomy of baby girl. The doctors there said they are completely confused as to why my Doctor would tell me the baby might need heart surgery when she wasn't even 100% on the issue and even if it was due to positioning like she 'claimed' at first, then a Level 2 US wouldn't be necessary. I'm just so grateful and thank God that my baby is ????!
