Q:How come my boiler supply valve isnt letting water into my boiler, i have a cold water supply hooked up to it with the valve on i have tested the copper pipe goin into it and water flows into it, but when It reaches the valve it stops. I understand that it my have a backflow preventer in it and I am wondering if that could be malfunctioning. The hole you see on the front is where my expansion tank screws in. Also where could I get a new Valve. Thanks.http://img149.imageshack.us/i/boilerfillvalve.jpg/: I work on antique steam boilers and engines for a hobby and if your supply valve isn't letting feedwater into the boiler, I'm going to tell you right now that you potentially have a VERY dangerous situation on your hands. Until you get this issue resolved, I would recommend that you not steam this boiler up under any circumstances, unless you have a backup feedwater delivery system that is working correctly. Many people don't know this, but a low water condition in a boiler under steam is essentially a ticking time bomb and can result in a fatal explosion. As to what may be causing it, I would say it's possibly one of two things: 1.) The check valve has been installed backwards and the flow of water is basically pushing it shut. 2.) The check valve is installed correctly, but is frozen shut due to corrosion and scale. Either way, I would have a certified boiler inspector come out and take a look at it; he can probably tell you more than I can.

Q:When looking at the head on my chevy 350 how do I determine which is the intake valve and which is the exhaust valve?: the intake valve is usually bigger and on the left. the exhaust valve is usually smaller and on the right. at least it is true in small engines (lawnmowers).

Q:Is it possible that if you never adjust valves the engine could lose a lot of compression? 1990 Suzuki VX800, 19,000 miles on the clock. No idea if it has ever had the valves adjusted, only got it 3,000 miles and 6 months ago. It is now not running and after a compression test, has 90 psi in the rear and 150 psi in the front cylinder. Don't really have the time yet for a leak down test. Could the exhaust valves be the cause of the low compression? thanks.: Yeah, valves should be adjusted from time to time, both intake and exhaust, they are the two biggest areas of the compression system that would cause low compression. That old of bike probably needs a good 'go-thru' to see what's happening, the leak-down is your best bet at that happening.

Q:My husband went to the doctor today, then called to say he won't be coming home because he has infective endocarditis. They sent him to another, larger, hospital in the region. Hours later he called and said that he needs surgery on the valve and they are moving him to another part of the country. I've been trying to read about it but I'm not sure I understand. What I've read says that they have to treat the infection with penicillin first, the he can have surgery. However, he's telling me he might have surgery when he get to the other hospital. He needs a new valve. Does this mean that his condition is worse than those I've read about or that they are simply doing things differently? Also, if you know. Does other illnesses make the risks much higher? He's got aspergillus in his lungs and have had 2/3 of the lungs removed. He has an immune deficiency (HIES) and he is physically weak from being sick. I know it's not good, but how bad is it?: Infectious endocarditis. Of course, any endocarditis is an infection. Rather like saying an 'infectious cold.' You will need to discuss this with his doctor to get good information. That means you go where he is. If you need to you make an appointment with the doctor at his office to find out. No way to know what kind of heart value issue he has or what other kind of heart condition he has.

Q:What are the function of reed valves on a motorcycle?: there are quite a few types,reeds/reed valve/disc valve..all 2 strokes have some sort of reed system...idea is that fuel is sucked past the reeds,these then close letting the fuel travel where it needs to go,opening when its time to suck fuel in....and so on

Q:I've been playing french horn in school for about five years, and I'm not exceptional by any means! But I love the instrument. Our school district bought a french horn a few years ago when we didn't have enough french horns for players. The almost new Holton has great tone. But unfortunately it fell into ignorant hands and has been neglected for two years. I just received the instrument and cleaned it up and got it back up to snuff, except for the valves. I can't get them to run smoothly!! They act all gummed up. I've put oil in the top and bottom of the valve, and I've dropped a couple drops in the tubes down onto the valves, but they're still gummed up! Do I need to use more oil?? Or what? Any suggestions?: The proper oil at the right locations should free up the valve. Sometimes the grease from the slide accumulates in your valve, but oil will loosen it up for a short while. Some sugetions are to take out all the slides and snake and flush them with water as best you can. You should do this to your lead pipe about twice a year as well. Reoil everything and regrease the slides with a quality product. If its still gummed up ,its likely you will need to have the valves removed and professionally cleaned.

Q:Which is worse ? And what causes it? I was told I had mitro valve prolapse but I m symptoms had worsen and so I saw a cardiologist again today and they said I have mitro valve regeritation.: MItral vale prolapse is the problem that is causing the regurgitation. Regurgitation is backward flow of blood. Prolapse is a situation where an anatomical part has slipped out of its normal position. When a heart valve is prolapsed it doesn't close completely, and blood leaks backwards when the heart beats.

Q:I'm taking a pipe fitting class and I can not find witch valve had the most restriction.: A globe valve has a lot of resistance (restriction) even when it is open A metering valve has adjustable restriction but i am thinking that that is not what you are asking.... A gate valve or ball valve has less resistance (a ball valve has almost none).

Q:do I need a new water heater or can this ne be fixed?: It can be Fixed. Try as Follows 1) tighten it up 2) Put some Silicone around it 3) Buy a new one a replace it. Make sure that you cut the water OFF before you Change anything out. Pop Off Valves are Not Expensive and are Very Easy to Change out. You need a 10 or 12 inch Pipe Wrench and some Pipe Dope. That is all. You unscrew the old one, put Pipe Dope on the Threads of the New one, and Screw the new one in. Takes about Five Minutes and maybe $ 10.00.

Q:I jsut got my valve cover replaced on my car what does that do?: Usually only the valve cover gasket needs to be replaced (unless you somehow damaged the valve cover itself). It does just what it says. It is the metal(2) located on the top of you engine that covers the valves. It needs to be replaced when the seals are allowing oil to come out.
