Q:Defects in which valves would produce the following?1) SEVERE DEPENDENT EDEMA?2) PAROXYSMAL NOCTURNAL DYSPEA3) CONGESTED LIVER?4) DISTENDED JUGULAR VEINS?5) PRODUCTIVE COUGH WITH FROTHY SPUTUMfor 1. i believe it's tricupsid valve, 2. mitra valve please correct me if I'm wrong. Thaanks!: Tricuspid regurgitation: Symptoms of right-sided heart failure, such as ascites, hepatomegaly, edema and jugular venous distension.

Q:i ha valveve a knock on the driver side .and i have to remove the intake manafold to get to the valve: valves don't knock and you can't get to them through the inlet manifold if it's the lifter you may be able to get it by taking the valve cover off but even then you sometimes can't and have to remove the camshaft

Q:Water has been seeping out of the sprinklers closest to the anti-siphon valve. Water seeps out of the sprinkler even when the anti-siphon valve is manually closed and not connected electronically. I opened up the anti-siphon valve to inspect the diaphragm, but there is no debris nor it was damaged. To be sure, I switched the diaphragm chamber of the two anti-siphon valves (a suspected leaky one and another good working one), but leak persists from the same sprinklers. I think the leak is from the (float?) rubber seal at the bottom of the stem closing the inlet valve. My anti-siphon is a Hardie (or Irritrol) model 311A series.1) Is my troubleshooting and logic correct? What other components could have contributed to the leak described? 2) At what scenario will water be flowing out of the anti-siphon cap?3) How can I determine if my anti-siphon valve has a vacuum breaker? What is a vacuum breaker good for?4)Which brand makes the most reliable anti-siphon valve?: If the antisyphon valve is not leaking maybe you should focus attention on the main valve ( assuming it is a solenoid valve) to see if it closes completely. Another thing, if the irrigation zone is on an incline then the water in the system will drain to the lowest point. Sometimes it drains slowly causing the impression of a leaky feed valve.

Q:I have a 78 honda hawkii 400 or cb400TII and I need to know what the valve gaping needs to be set to: Cb400 Hawk

Q:So my engine was back firing and me and my dad adjusted all my valves both sides. Runs better, But it still back fires. What could be the problem? Its a Chevy 350 with a brand new mild cam. 600cc carburetor. And new shorty exhaust headers. However I don't have exhaust pipes on my headers just yet because I gotta get pipes to mesh properly with my exhaust. Could it be air coming back up from the pipes causing it to back fire a bit? Like I said we just adjusted all the valves.: Could be back pressure from the short pipes, could also be bad valve timing, you might have to tweak your cam

Q:Are these valves are a kind of heart chambers pressure sensors?What is keeping them interlocked 2x2?: It's all mechanical. The valves are passive things kind of like a screen door. When you push on them from one side they open, when you push on them from the other they close. The valves are assisted by some fibers attached to the inside of the heart similar to the way a screen door is helped by a spring attached to the door frame. It's the flowing blood that pushes the valves open or closed as the heart pumps. The path that the blood follows in the heart as it beats happens to make it so that the valves close two at a time. This is because the heart is actually four separate pumps that work two at a time. There's no direct electrical connection to the SA node. The only way they're connected is that the SA node firing is what causes the heart to pump, causing the blood to force the valves open.

Q:I have a Ford Explorer 4x4 2004 model.The check engine light soon has been on for two to three weeks, I finally got it checked and they said i need my ERG valve cleaned. They quoted it for around 50 bucks, which is fine. However, i dont get paid until a week from now. Will it be alright until then?What are the effects of a dirty/faulty ERG valve if not taken care of??There are not sputtering or anything abnormal that i can tell..Thanks.: You'll be fine, drive it.

Q:My new Trek 1000 has a type of valve stem different from the standard (car type) stem on my mountain bike. Do I need an adaptor to fit it to a pump or do I need a whole new pump? Also, have you seen a tire gauge that fits this stem type?: Bike Valve Types

Q:Is there a product that can fit over a foot valve to give it further protection in muddy water? I am looking for something for forest firefighting in mind. Something like a screen box something else that can give it further protection. It would be nice if it was small, and compact. Pictures would definitely be an asset. Thanks to everyone that answers. Greatly appreciated.: most foot valves i have bought come with a strainer attached perhaps you should look for that type. if your valve has a strainer you may consider making a further coarse strainer out of a ball of chicken wire and place this over the foot valve assembly(thats what i do for the cold water supply to my house) don't compress the chicken wire very small as it will block up i tie the wire filter on with galvanized wire then i can easily replace it if necessary ps i tried stainless steel pot scourers but they were to fine and blocked easily

Q:My sprinkler valve I just put in leaks from the top knobs you turn to allow water to pass through to the 3 main pvc pipes. I turn the water on on the main water line, open the little black twisty knobs to allow the water to pass through to the irrigation lines, but water leaks out through all 3 black twisty knobs. What do I need to do?!?!?!: I have been given the equivalent line from our water application while the strain valve broke and blew up our water softener it is the 1st concern on the line from their tension regulator. fortuitously, it has a lifetime insurance yet their plumber urged me that it incredibly was once the duty city on account that of the strain regulator which they admitted to being at fault as quickly as they replaced it.
