Q:A customer has a G. E. SmartWater waterheater 7 the drain valve leaks, is there a gasket that can be serviced?
If it is a regular brass valve, you will have to drain the tank first, then replace the washer in the valve with one rated to be used for hot water. You replace the washer just as in any valve by removing the bonnet and stem. there you will see the washer. You may want to clean the area of any calcium carbonate that may had developed on the seat before putting it back together. If you decide to replace the valve, it is a 3/4 inch male NPT hose bib valve rated for hot water service. Personally, I've always thought that if I ever had to change one of those valves, that I would replace ti with a good ball valve that had a threaded hose end screwed into the discharge end for better drain flow. The whimpy valves that they put on water heaters is pathetic! If you use your favorite search engine and just search for water heater drain valve, you will find all kinds of cool replacement valves!

Q:Help with a leaky valve..
There is a small nut around the valve handle on the valve tighten this one
Q:Articifical Heart Valves -?
There are three of these things: the caged-ball which utilizes a metal cage to house a metal ball, tilting-disc valves, which have a single circular occluder controlled by a metal strut. They are made of a metal ring covered by a tissue, into which the suture threads are stitched, in order to keep the valve in place once implanted and there's bileaflet valves, which consist of two semicircular leaflets that rotate about struts attached to the valve housing which is the most recent type, eh? So heart valves are considered to be extremely durable. They're made of either pyrolytic carbon or titanium coated with pyrolytic carbon, and the sewing ring cuff is Teflon or polyester or dracon (probably dacron :P). They key to the materials chosen is durability because of the constant fluid flow. I see this as pure engineering, not medicine, specifically fluid mechanics: like if there are rare complications for example thrombus formation is a debilitating side effect of high shear stresses created by design of the valves. Ideal heart valve from an engineering view would produce minimal pressure drops of course have small regurgitation volumes because it's supposed to minimize turbulence and regulate the flow.
Q:Evap vent valve?
Theres 2 valves . 1 is electronic , the other is a manual valve in the canister. The valve is normally in the charcole canister. These canisters have been pretty much the same design for years. You could probably find another at a junk yard to fit , even if it was a different year/body. Seeing how a code finder found it . It's probably the electronic valve. It is a simple open close valve. 1 connector and usually 2 vacuum lines. You can also plug the line going to the intake. this will prevent a lean mixture from an unregisted air leak. The valve is used to direct tank vapors that accumulate in the canister at start up. At start up the valve opens and the engine sucks gas vapor from the canister . once the engine is started the valve closes .Vapor gas has a quicker ingnition point then liquid gas. A quick fix would be to simply plug the line going to the intake , with a bolt or screw to fit the end of the hose. This is only to prevent a lean mixture from air getting in behind the mass air flow sensor. The light on the dash will come on when the O2 sensor in the exhaust smell the lean mixture thats not being adjusted by the injectors as told to do. I run an older multi port fuel injected truck and have compleatly blocked all the emmisions systems off and removed them. It's only an emmisions device , it has nothing to do with the preformance of the engine (unless it allows a leak). Just plug it and have no worries of it becoming a problem
Q:a few questions on prosthetic heart valves?
Blood clots can form with ANY type of surgery or disease that interrupts the natural flow of blood. Anticoagulants do not cause a bleeding problem, they keep the blood from clotting if that is what you mean. People who take them have to have an INR checked (clotting time) to make sure that the blood is not too thin. It is a delicate balance. One must be careful on this medication when having any kind of surgery (usually have to stop the medication a week before and a stay off it a few days after according to their doctor's order) because it could cause them to hemorrhage.
Q:Trumpet valves making weird sound?
I don't think anyone knows, because there's multiple Bibles. And people interpret it their own way, and re-print it with different scriptures. As far as I'm concerned, there is no such thing as a REAL bible anymore. And any beliefs we have today about it are all false. According to one bible, you will be sent to hell on both counts. According to a modern version, you will be excused for doing your wife, and in another bible, you'll be stonned for asking this question (Knowledge is a sin) Interesting that we are the only intelligent life on earth, supposedly made in God's image, and yet the bible says to stay away from the tree of knowledge. Sorry, I don't buy into that bullcrap.
Q:Question about gas valve on grill?
The valves on the grill itself are the ones that allow the gas to flow. As long as you have no leaks between the main valve and the grill valves, no gas will flow when the valves on the grill are turned to the off position.
Q:What would happen if the EGR solenoid valve isn't connected properly?
if the spark plugs are bad the oxygen sensor with sense the exhaust is not hot enough and the computer with allow the injectors to let more gas in thinking that since theres no fire it needs more gas causing it to run like its flooding and exhaust readings will be high. make sure the air filters clean
Q:Does valve oil and/or slide grease expire?
As the others have pointed out, no, it doesn't expire, but I never use old grease myself. You get lots of spit transfer from whatever you're lubing up to the grease/oil and the bacteria from said spit has just been.. sitting there. Growing. And possibly multiplying. Sorry. I'm a germaphobe. That's just yucky to me.
