- Q: Hi. I am planning to install new kitchen faucet and noticed that there are two shut off valves under the sink. One of them is badly rusted and needs to be replaced. I noticed that it is connected to three pipes (one of which is kitchen faucet). The other is clearly water coming in. What is the third one connected to wall? Also how should I go about replacing this? Anything that I should be careful of?
- You have to shut the main water supply off when you change the valve. It will either have a compression fitting or female threads on the part that connects to the water inlet from the wall. Make sure you get the right type. Use two wrenches when you change it. The extra line is probably for a dishwasher. Dishwashers do not have their own water supply lines. Hope this helps. Gerry Barr
- Q: I am 16, and i have a leaky heart valve. What makes it worse so i can try to prevent from it getting worse? please help.
- Not much can make it better or worse as long as you are in good health and are taking care of yourself. One thing that is very important when you have valve issues is to stay hydrated.
- Q: my dad's friend died, and dad had been keeping some valves of his. now we've been left with about 400 valves and i'm going to sell them.my main question is what are they used for? i need to write a description for ebay but have no idea what they're for! anyone know?also, how much should i sell them for? on the box it says 11 shillings, which i worked out as ?1.32, but how much should i sell them for on ebay? there's prices on ebay that are about 50p to ?1.50 for most of them, but some are about ?7 but have no bids at all. how much should i start the bidding at?also, if you could give me any other information that i should put in the description, i would really appretiate it :)they are mainly 'Mullard' valves (the company name) but some are 'MAZDA'thanks! :D
- It sounds like 1960's 70's 80's radio and tv valves. pcl 85, pl504, py800, ef80, pcl82, maybe. I through away about 100 of them about 10 years ago. I wish i would have kept them. They are of interest to vintage radio and tv collectors. Could try selling a few at a time number should be on the glass. Still used in high quality audio amps and output stage of guitar amps for warm quality sound. Good luck.
- 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: I have a yamaha cornet and i took the valves out to oil them. i put the valves in, and now only the middle on makes a sound. when i put down no valves, and doesn't make a sound, only when i press down valve two. i think it is the way i put the valves because it has those holes. can some one let me know what is the right way to put the valves in, like explain or show me a video. thanks.
- I play a baritone, but I hope I can help. On my instrument there are little notches at the tops of the valves. I had to spin my valve until I heard a slight click then I would push down on the valve to make sure it worked. (I would start on the first valve) Then to make sure that I had it in right I would blow in the instrument to see if the air went through the holes. Try that, it might help. Also, the next time you take your valves out keep them in order and in the position they came out in.
- Q: Cylinder head valves.Can't really differentiate the difference between burnt and just carbon build up on valves. Are they the same?If I the valves have no cracks or holes, can I clean the carbon off of them and reuse them.If they don't leak when I re-leak test them, are they then good to use?Had very little compression in one cylinder.What cleaner is safe to use on the valves?I know I should replace all, but any money I can save right now, helps a lot.Also I seen a method of re-lapping the valves by using a tool (stick with a suction cup on end that sticks to valve surface) that you spin while valve is seated. It refinishes the seat and recreates the seal/re-laps. Appears to work and seal just fine. Anything really wrong with this method?

- Q: What exactly are valves and cylinders when talking about car engines? Say a car has 3 cylinders or 8 valves for example.
- There are intake valves and exhaust valves. On the intake side, the intake valve opens which lets the fuel/air mixture into the combusion chamber. At some point (measured in degrees of crank rotation) the intake valve closes, the air/fuel mixture is compressed and ignited by the spark plug. Then the spent mixture exits the cylinder when the exhaust valve opens. Valve configuration varies somewhat, but regardless of how many valves there are there will always be at least one intake and one exhaust valve. Some cylinder heads have 2 intake and 2 exhaust valves which is what is described as the 4-valve per cylinder setup. Regarding Car Cylinders, the answerer says Cylinders in a car engine are pretty much like rowers in a boat. But they are not. Rowers always row in synch with each other. Cylinders are made to be out-of-sync for smoother operation. The more cylinders you have, the smoother the engine runs. Compare a 1-cylinder minibike with a 4-cylinder motorcycle (both air-cooled), or a 4-cylinder to an eight... big difference in smoothness.
- Q: -air pressure of 40 psi only -run on 12v or 250 vac-no need for half open or any of the options i just want it on or off-it will be for a costum use so i dont need any special designs for it any thing will work -it also can be change from gas to water if

- Q: i have a yamaha trumpet. i got it brand new and it is 3 years old. I recently did drop it and i have a tiny dent on the last turn to the bell. after that they started sticking .

They also did an ultrasound cleaning i think it is called . they are still sticking. Please any think that you can suggest i showed my band teacher who suggested going to Quinlan and fabish. Then my trumpet teacher who said i need to oil more after the cleaning please help
- Check that you are not putting sideways pressure on your valves when you press them downwards. Even on a good horn this sideways pressure can cause friction between the piston and the valve casing. Avoid this by arching your fingers a little, depressing with your finger's tips, and avoid the pinkie finger ring entirely. Tying your pinkie up in that only restricts your 3rd. finger's freedom of straight downward movement. Over- lubricating the valves can be as bad as too little oil. Do the whole warm bath treatment that you would normally do to clean it, add 3 drops to each valve, work horn for a few minutes, wipe valves with very old (washed heaps of times) t-shirt: then finally 2 drops again. If this doesn't work, get a trumpet specialist teacher to take it home for this treatment.(You might not be bathing it right). Failing that, check my web site's repair section. Good Luck!
