Q: hi im 13 years old and i am having my tricuspid valve repaired or replaced the doctors do know what they are going to do yet.what is the success rate of the operation ?and whats the survival rate of the operation ?all other info would be appreciatedthanksalex: Any type of valve surgery involves exposing the aorta of the heart, therefore it is a form of open heart surgery. Over time, this has become a relatively basic procedure for heart doctors and it has a success rate of almost 80-95%. There is a chance that you might need another surgery afterwards, but that only happens in about 5-10% of patients that get the surgery. The survival rate for this operation is very high and only 5-10% of patients experience any negative effects during the surgery. This includes infection, stroke, allergic reaction, or bleeding. I will keep you in my prayers Alex. Best of luck to you!

Q: I need a bit of help. I am trying to find the location of the EGR Valve on a 1992 Chevy Cavalier 2.2L. If anyone can help me out by posting back a picture or diagram that would be great. I found all the text directions, but did not find that to be helpful.Thanks,: Ok here we go First raise the hood the engine sits side ways. now on the Passenger side of the Engine compartment is the engine. (i'm serious here) the end with the belt and the pulleys wil /and is Called the front even thou it sits sideways. now the thing on top of the engine is called a valve cover start looking from the front and follow it to the back (that's toward the Drivers side) when you get to the end of the valve cover look down you will see a Valve about 2 inches below the valve cover it has a black Vacuam line that runs to it this is the EGR valve. now Why in the world do you want to make it open on a 1992 Cavalier. most of the time we replaced them because they stuck open and caused idle problems. if your trying to just keep the light out Good luck

Q: The shutoff valve for the hot water under my bathroom sink has a very tiny leak. It is coming from where the turn knob meets the valve.So long as the valve is either all the way open or all the way closed, all I get is a single drop every couple seconds. But if it is anywhere in-between, it is a pretty steady drip.What's the simple/quick fix for this? Replacing the entire shutoff valve is probably not an option because it is an apartment complex.: In this case, the terms simple and quick do not apply. What's happening is the valve packing gland is leaking. That's the seal around the valve handle that keeps the valve from doing what it's doing now. The valve needs to be replaced--period! It is actually the simplest and quickest fix for the problem. Of course the water will need to be shut off while it's being replaced. The good news is that a competent plumber can do it in fifteen minutes unless he runs into problems. Then, it can take up to 3/4 hour. Your landlord needs to address this issue.

Q: I need the valves that I need to press down for the notes on the bass stave. Can someone please write them down for me in a list like this?F = openG = 1 and 3A = 1 and 2 etc.Thanks people.: I'm sorry I don't play the tuba and so I don't know, but please don't refer to a tuba player as a tubarist! I mean, I got a good laugh, but that isn't a word. They're called, tubists.

Q: so here are the details. i've been using my trumpet for about 6-8 years now and 1 if not 2 valves get stuck on my trumpet. the problem is not the oil as i have over oiled them too and no go. its that when i try to put my valves back in their place and twist them they don't stay in place,move ,and making either my valves stuck or making my trumpet not do a sound. what should i do? repair shop or buy a new one? i hear the clicking sound when i put them back but still all that does is either make my valve more sticky: You really need valve oil I have used olive oil in a pinch

Q: I have a hot water oil burner. I need step by instructions on how to replace the pressure relief valve.Do you know?Please help me.: Your precise, the priority could desire to have long previous away with the previous valve. Your new valve could be defective. in the previous you substitute it however there's a reliable probability your furnish rigidity is to extreme. it must be filling at a extreme rigidity to start with and then as quickly as heated it exceeds the shrink. This sounds like a greater sensible clarification and could greater healthful the priority. while you're hooked to a municipal water furnish they could be in possibility of pay the cost of having a ''rigidity regulator'' put in. or you will could desire to foot the bill.

Q: I have a question about my car. The mechanic told me that my valve body needed to be rebuilt. However I read that the valve body is a sensor that tells the car when to shift gears. Now my car is a semi automatic so I can shift gears myself! I was wondering if someone could tell me whether it was still necessary to rebuild it if I'm going to be shifting gears myself? I just don't want to mess up the valve body even more and eventually have to get a whole new transmission!: Its an electrically shifted automatic. The valve body is not a sensor it is the valving system that sends fluid to different parts of the transmission to shift gears. The solenoids on the valve body move the valves dependant on what the computer tells it to do. The paddles or shifter you have do not go to the transmission but to the ECU and the ECU decides what to actually do with the transmission. It does not matter if you shift it or let it do it its self if the transmission is going out it needs work or rebuilt, it WILL fail sooner or later and leave you stranded. So you either need to get it rebuilt or get another transmission. If you drive it until it fail you will need another unit, if you fix it now yours might be able to be saved.

Q: hi i just found out i have micro valve i and have allmost 30 years with willam sydrome any doctors know more what can happen what dose walking or others got to do with the valve will i stand for a longtime walk jump will one side get weeker then the other what about my hands and eyes my knees what will happend over the years when i get older ?: I have a mitral valve prolapse. Don't know if this is what you meant or not, but it can lie dormant for a long time. I thought I was hvaing a heart attack!!

Q: What exactly is a flow valve for an ice maker on a refrigerator? Any idea what it would cost to replace it? Is it easy to replace?: A flow valve is a type of electronic solenoid that controls when how much water goes into the ice maker. I'm not sure if your ice maker sells the part or not, you can check online call your manufacturer. It might actually be easier to replace the ice maker. I would guess that ice makers cost somewhere around $50 - $75 are pretty easy to do yourself. I hope this helps.
