Q: Since the valve drain is usually open, I am wondering if placing the cap on the drain has made my water heater dangerous.: Easy method, change washer in valve Right method: Turn off main , attach hose to existing valve, route out side to a point as lows with respect to furnace height, open valve and drain water, remove plastic valve. Sweat on new brass valve with torch, turn main back on or just keep bucket under to collect drips and finally Pressure will not build so the thing is not going to explode or any thing - i.e. you are safe E-mail me if you don't fully understand Joe

Q: Someone explained on chevy that valve guide clearance can limit lift.: Valve guide clearance is distance between the valve stem and the valve stem guide. It is critical for proper engine operation.

Q: ok im buying an aftermarket blow off valve for my car. the car itself is taken apart completely and i have no idea wht vacuum lines go where. i know tht the top nipple of the bov has to be connected to the throttle body but it has 5 lines. does it matter what line is connected to it?: Don't do it. First of all, if you knew enough about turbo charging or supercharging, blow off valves, bypass values, hooters, etc., then you would have known we need to know the size of engine, model of turbo, piping diameter, etc. The actual control lines are not that complex. By using your tongue you can tell what each line is ported to, and then you just need to know if you blow off valve is operated by vacuum or lack of vacuum. They make both types. And your throttle body will have ports on both sides of the plate. And yes, it does very much matter. Turbo charging is not for the novice to fool around with.

Q: hi guys..What is different between globe valve and stop check globe? Is that stop check globe=SDNR JIS std?: I am not even sure what you are talking about. a globe valve is a type of valve that can stop the flow by turn a handel on top of the valve. A check valve on let the flow go one way and stops the flow the other way. hope this help Globe valve From Wikipedia, the free encyclopedia Jump to: navigation, search A Globe valve is a device (specifically a type of valve) for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.[1] Globe Valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug[2] can be screwed in to close (or shut) the valve. The plug is also called a disc or disk.[3][4][5] In globe valves, the plug is connected to a stem which is operated by screw action in manual valves. Typically, automated valves use sliding stems. Automated globe valves have a smooth stem rather than threaded and are opened and closed by an actuator assembly. When a globe valve is manually operated, the stem is turned by a handwheel. Although globe valves in the past had the spherical bodies which gave them their name, many modern globe valves do not have much of a spherical shape. However, the term globe valve is still often used for valves that have such an internal mechanism. In plumbing, valves with such a mechanism are also often called stop valves since they don't have the global appearance, but the term stop valve may refer to valves which are used to stop flow even when they have other mechanisms or designs. Globe valves are used for applications requiring throttling and frequent operation. For example, globe valves or valves with a similar mechanism may be used as sampling valves, which are normally shut except when liquid samples are being taken. Since the baffle restricts flow, they're not recommended where full, unobstructed flow is required.

Q: Why is the atrioventricular valve in the right ventricle called the tricupsid valve and the atrioventricular valve on the left ventricle called the bicupsid valve?: The TRIcuspid valve has 3 pointed flaps; the BIcuspid valve has 2 pointed flaps, and a cuspid is a point (just like your bicuspid teeth have 2 points).

Q: I need to make a ball valve that will open with no manual force but by a motor of some sort to spin it and release water. how do i make a ball valve controlled by preferably a motor or other CHEAP device. I need to do this for less that 20$: put a slave servo on it,

Q: My third valve won't move at all. I haven't played my trumpet in a while and I tried to oil it to get it to unstick but it still won't move at all. People say to screw it off but I can only unscrew the little cap at the bottom of the valve where you push in, not the white button at the top. Help please! Thank you so much! =]: i got here across that Dennis Wick valve oil is a procedures more advantageous ideal to any that I easily have used. you'll locate it on Amazon. If cleansing with dish cleansing soap and heat water would not artwork, alongside with the Dennis Wick oil, I recommend that you're taking it to a restoration shop. be careful at the same time as cleansing now to not get any cork or felt moist. only dip the truly valve section into the water.

Q: What are Atrial valves??: I've heard the term sometimes (though rarely) used instead of atrioventricular valves, the tricuspid (right) and bicuspid valves.

Q: Hi, this is a part 2 question to the one I posted last night. After turning the water shut off valve on my toilet back on, it didnt start to hammer till about 1 min pasted. When the hammering is happening I look in the toilet tank and see air bubbles coming out of the base of the fill valve and the water coming out of the fill tube isn't smooth and flowing its kinda step wise/ in intervals. I forgot to mention that I live in an apartment, does this affect anything?My official question is, is this an air bubble problem or is it a rubber gasket/ rubber seat problem?This is a new building only about 2 yrs old, so parts can't be that bad right?: First check for a kinked or twisted supply connector hose. You may also have a piece of rubber gasket/washer debris stuck in the valve body (seat washer) or in the fill valve itself (from the connector compression washer). Shut off the water supply at the angle stop and disconnect the supply hose from the fill valve nipple under the toilet tank. Get a bucket and put the end of the supply connector hose/tube into the bucket and open the supply valve again. If it still hammers when unrestricted like this, the obstruction is in the anglestop valve body. The water pressure may force it out, but if it doesn't, you'll have to shut off your main water supply to clean the stop or replace it. If it doesn't hammer when unrestricted, the problem is now in the new fill valve, and is probably a deteriorated piece of the compression washer in your old supply connector hose or tube that has been pushed into the fill valve. Since it's a Fluidmaster, you can disassemble the head of the valve and remove any visible obstruction or just replace the top part.

Q: I am a 55-year-old female going in for mitral valve replacement surgery, and I need to decide on which valve to get: bovine or mechanical. If you have any experiences or know anyone who's had either of these types of valves placed in their bodies, please elaborate on the experience. I want to know the pros and cons of each.Thank you.: I had open heart surgery, repairs to my mitrial and tricuspid valves. On the mitrial valve, an Edwards Lifescience ring was placed to tighten valve and the tricuspid was just tightened. That was five yrs ago. Have more energy and feeling better, still. My surgeon did mention placing a porcine valve but once they got inside my heart, the DRs. choose the lifescience ring. I do take an anticoagulant but for other reasons for over 8 yrs now.
