Q: when there is fire in the building, the solenoid valve is activated but what happen inside the cylinder actally?: If the pressure in any one zone is different than the other zones it could be one of two reasons; either the pressure is high (usually due to one or more sprinkler heads not poping up), or its low (usually due to a leak in the pipes). Something that could cause low pressure in all the zones are an obstruction in the water line above the valves (unlikely), or a hole in the line above the valve (the water would be filling the valve box and causing damage to the lawn wherever it is located), or leaks in all the lines (again would be easy to identify from the excess water in the ground at the source of the leak). Lastly the valve itself could potentially be faulty. The solenoid inside the valve holds the valve open when electricity is applied across it. If the wires to it are damaged; if the solenoid is bad; or if the valve has any rust or dirt inside that could cause a lower than normal amount of water flow.

Q: What is a valve mismatch in cars. code 300, 302, 420. All togather. Mechanic is telling the truth to do tune up and all. Is iT valve itsef? What is a (bad) coild? MITSUBISHI MIRAGE 2000: Wherever you are get out. You are about to be ripped off. This will probably be too late. I gather the code you gave is the trouble code, as they are called, from the cars obd. The code 300 is random / multiple cylinder misfire. The code 302 is cylinder # 2 misfire The code 420 is catalytic system below threshold bank # 1 Deciphered this means you have a spark plug misfiring in cylinder #2, bank # 1. The misfire is causing a rich gas mixture in the exhaust system that is detected by the sensor and therefore it says you have a catalytic converter problem. I would suggest you replace your spark plugs, if they have a lot of miles on them. Are they the original plugs ? I f so they are probably due. Get out of there and go find an honest shop that will not rip you off. Now that you know the problem they can;t cheat. I don't know what all that other valve business was about but all you have is a misfiring spark plug.

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: 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: Valve seat is the actual area on the head that the valve rests in when closed. Dropping a valve normally means that the keepers have come loose or a spring has broken and the valve has dropped into the cylinder. This was a common occurance when some one has modified an engine without upgrading the valve train especially in older engines.

Q: What is the easiest and best way to fix a leaking shut-off valve on a toilet?: Take out the old one. it is easy it just slides up the over flow tube go to a hardware store and get a replacement ball valve (Ballcock) they are just a couple bucks.slide the new one on! Take the old one when you go to get the new one.

Q: I have 3 such valves in the line and none seem to be able to move past 10/4 oclock position and water remains on. Is there a way to adjust valve? Seems there is slot for screwdriver in center of valve.: The threads are stripped, you will have to get a new one, until then shut off main line into house if you are flooding

Q: I play the trumpet and I took it home for Christmas Break. On Friday I am playing Amazing Grace at Church for New Years Eve, but the problem is my valves on my Trumpet is sticking and I don't have any valve oil for it. Is there any other oil that I can use for the Valves? It will be really great! Thanks :): valve okorder /... its simply the best

Q: 12 valve: Un plug the vacuum hose on top of the valve, loosen and remove the big tube nut on the bottom of the valve, I have found if you hit it sharply with a hammer 3 or 4 times before you try to loosen it won't break the valve off, once the tube nut is undone remove the 2 bolts holding the EGR valve to the intake manifold. Remove and discard the gasket and install the new valve in the reverse order. If the tube nut still won't come loose try heating it with a torch, if it's really rusted on you might have to replace the EGR tub along with the valve.

Q: Hi My sons car has alloy wheels, and metal valve stems, there is a tiny leak between the valve stam and the alloy on one wheel, we are struggling to get anyone to repair at a reasonable cost. Would tyre weld make a permanent repair?. Some tyre specialists won't touch the wheel, one other wants to drill out the stem put in another, which sounds a bit drastic. Any other ideas?, is it feasible to get the metal valve stem replaced by a rubber version?. Apparently the metal ones get curbed and then start to leak.: On that year car the tire is tubeless and the valve stem should not be moving as it would if you had a tube type tire. If the valve stem is pushing in it means you drove on the tire while flat and probably ruined the tire as well as the valve stem. The tire must come off the rim to be inspected before blowing it back up and used. If you don't inspect the tire it will probably blow out at highway speeds and kill someone!

Q: I saw that they sell a kit to block off the egr valve in my dodge neon. Since this was on a performance site what will this do? Will blocking off the valve give me more horsepower? Should I do it or not? Thanks: i own a repair shop,and it wont give you much more horse power if any,all it does is stop the egr valve from working ,the kit allows you to remove the valve and put a block off plate on it,some say it helps a little i haven't noticed much of a difference in the vehicles that have them on,they just don't recirculate the exhaust gases like they should,which causes any car to fail an emissions test,that's about it,good luck,i hope this help,s.
