Q:we are having diffaculty with our spa and our jacuzzi. sometimes when we try and heat the spa the pool gets heated.first of all we would like to make sure the valve diagram is right because sometimes also the spa dumps about half into the pool. frustfrated can any one help?: You have one or more faulty valves or you've got them turned the wrong way for the operation you want. You also may have a check valve that's going bad. The problem is that I'd have to see the setup around the pump and filter to even get an idea of what goes where. My pool has electric activators for the valves that allow automatic operation from inside the house. I adjusted one incorrectly once and it activated the valve backwards, and I had to readjust it.

Q:Does anyone know what those valves are/do in my picture?http://img223.imageshack.us/my.php?image=dsc00531it9.jpg: To me that is a water mixing valve used in showers, you can see the plug on the top, so when the face plate is attached the tap tops are fitted to either side of the spout.

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:How would this affect the functioning of the heart valves?How would this be detected in a routine examination?: If the heart valves are damaged, they may leak, causing regurgitation of blood. For example, if the mitral valve (between the left atrium and left ventricle) leaks, blood will leak back into the left atrium when the ventricle contracts. This reduces the efficiency of the heart contraction. Regurgitation is easily detected by echocardiography. On routine physical exam it may be detected *if* there is enough leakage/ flow abnormality to cause an audible sound, or murmur, that your physician can hear with his/her stethoscope.

Q:I have a T4-T10 and L5-S1 spinal injury and I recently found out that my tricuspid and my mitral valves leak. I have never had heart problems before I got the spinal injury. Do you think the valve leaks could have been from the trauma when I received the spinal injury?: Maybe but usually MVP doesnt give people much problems and if it does usually sudden

Q:In aircraft reciprocating engine, if valve spring surge happen?1. Why happen?2. Affect to engine?3. Result?4. Feeling?: Its in a car engine but the fault is near the same. The good news is that in aircraft there are mostly multi-spring valve springs to help prevent the resonance problem that can happen with a single spring. (If one goes resonant, the other one doesn't.) I think what that means is that if you have valve spring surges in an aircraft engine, you probably have a broken spring or weak on the assembly. (just a guess but if they don't go resonant at the same time then how would you get the surge?) The affect, not good. Result - rough at a certain RPM or range of RPM even temp. related Feeling - rough

Q:i know its going to drop some oil, im just wondering to what extent? how much oil is going to spill out?: The answer Briggs gave is pretty much on the target except I believe he missed your primary question: will oil run out of the valve cover and get onto other engine parts. The answer to this is most likely but there are some precautions you can take to minimize the oil. Assuming the engine is fairly clean inside, the oil galleys should allow most of the oil in the upper head/valve spring area to drain back into the engine. If the engine has set and not been run for several hours (over night?) the majority of the oil will have drained out of the head area. There will be pockets of oil trapped in the upper head area but that most likely will not run out when the cover is removed. First thoroughly clean the valve cover(s) so no dirt is present to fall into the open head area. Get some absorbant towels (paper or cloth) and pack around the head below the valve cover gasket line to catch and absorb any oil that might ooze from under the valve cover when it is unbolted and removed. After getting the valve cover off, make sure the absorbant material is still in place and if necessary, you can absorb the pooled oil pockets still in the upper head area to prevent seepage from these area. Good luck.

Q:what exactly is thc pcv valve and what does it do: The positive crankcase venitlation (PCV) valve allows a vent for gases which naturally buid up in an engine. In the 60's, it was vented out into the atmosphere. California Air Resources Board (CARB) passed legislation stopping the practice. Instead of venting, it now burns through the normal combustion process. The PCV valve regulates how much is allowed to pass through, because, at idle, if too much is allowed to go into the engine, a rough idle or stalling would occur.

Q:i have a puegeot 306 turbo diesel and apparently removing the EGR valve helps with engine noise and the smokeyness of the car. Is there any downside to removing it?: It will throw off the computer, and cause the check engine light to come on. Other than that, no.

Q:does anyone have a bicuspid aortic valve and wrestle? my cardiologist told me that wrestling would put too much strain on my heart but i can feel that i'm fine when i wrestle so if you have a bicuspid aortic valve and wrestle or know anyone who has that disfunction and wrestles please let me know: definite you will possibly have constantly had this, it fairly is a few thing you have been born with. a typical aortic valve is tricuspid, it fairly is it has 3 ultimate flaps, yet a bicuspid valve basically has 2 flaps. now and back those bicuspid valves supply no problems, yet in some people they could bring about heart murmur later in existence ( usually on your 30s or 40s ) via fact they permit a sprint blood to leak back the incorrect way while they are closed. If this gets intense sufficient, you are able to need surgical operation to in high-quality condition a man made valve. it fairly is exceedingly usual those days and not some thing to rigidity approximately.
