- Q:I couldn't get a name off the valve as it sits. It has a leak on the top plate and i'd like to replace the valve plate as opposed to cutting the whole thing out and replacing.
- i have seen many types of valves on an everyday basis. and i havent even seen one like this. its most likely a cheaper knock off brand valve. you have enough room to replumb a new one in quite easily. if you do not have enough room right before the valve to just cut it out, cut the pipe on the other side and unthread the valve from the threaded fitting. then buy some fittings and pipe and replumb it. you have a lot of room to work on it. i doubt you will find the same valve to part it out with. use either a Hunter valve or a rainbird valve avoid toros, orbits, weathermatic, and lawn genie parts. good luck and just take your time.
- Q:I was told Wed. that I need to have my aortic valve replaced. I was wondering if anyone could share their experience with this surgery good or bad. I am meeting with the surgeon on the 26th, and am very nervous. Any tips and or suggestions appreciated. I'm a 39 year old female.Thanks in advance
- if you have a tissue valve you will not need to be on coumadin the blood thinner but will need to have surgery repeated later on in life. if you have a mechanical valve placed then you will need to be on coumadin and typically it takes about a week to get your blood theraputic, then you will need to probably need to have you blood drawn weekly a few times immediately after. then it tapers down to once a month checks generally. goofd luck to you.
- Q:How do you take out a valve stem?
- No. The cap just keeps dirt, debris and moisture out of the valve stem and core. If you remove the valve core (it screws out with a special tool) then yes, your tire will go flat in a big hurry. To remove the complete valve stem as a unit there is a tool that screws on to the end that you can use to rip it out of the wheel. A new stem has to then be inserted from inside the wheel requiring the tire to be dismounted.
- Q:Can anyone tell me what to do if i know that I have the type of valve stem that was recalled TR413chrome?? Will they replace them for free since they are a recall or do I have to dish out some more $$ to fix the problem??? The company that sold them to me is in Florida (Wheelmax) and I am in Mass. Not sure what to do to avoid having to pay out more $$ to have them replaced...any help is greatly appreciated
- Get okorder Take care.
- Q:I want to install a hks blow off valve on my car but is it true that i need a turbo installed first in my car or not.and are they legal in the state of californiapermitted,i want my car to make that air release sound when i shift gears,but it needs a turbo installed or can i still get what i want from a blow off valve without a turbo!!!!!
- If you keep asking this question you may be able to find someone that will tell you that it will work.IT WILL NOT.You have no excess pressure to blow off.No turbo= no boost=no pressure.Record the sound that you want,wire your play-back to a micro switch on the clutch with a P/A speaker under the hood.That's as close as you can get.I'll put it in simpler terms.I T W I L L N O T W O R K.
- Q:I am doing a big project on Valve and it's games. I am currently doing some research on the company and wanted to see if anyone had any interesting facts or information about Valve that may be useful when doing research, thank you. :)
- Google can help
- Q:P.S.V. Pressure Safety Valve
- psv is a pressure sensitive valve the other is sspring loaded and will fail in time
- Q:I've never replaced a shut off valve before but am wondering if there are any tricks in freeing up a stuck valve that wont close. Can this be done so I don't have to call anybody?
- When valves are turned all the way in an open position they tend to get stuck. Try a heat gun but make sure you have a copper line feeding into the toilet tank, not a plastic one because it can melt. Just heat the valve for a few minutes at a time, because over heating it can damage the rubber washer inside the valve. If all fails then it has to be replaced by someone who is knowledgeable.
- Q:Is there anyway, from home, that I could rule out a bad heart valve as the cause for my heart palpitations and arythmia?
- As a physician, I strongly recommend you to visit a ER (Emergency Room if you were from UK) and explain the doctor what is going on. I also would recommended ACE inhibitors, since they prevent cardiac muscle remodelling. I can think in several other things, but I need PE and a new echo-cardiogram to make a decision (indeed a ER doctor must make those decision)
- Q:I have a Burnt Valve in my Ford 302 EFI Crown Victoria. I know that i will have to have machine work done to the head but im not even gonna mess around im going to just pull both my heads off since theres alot to remove to even get to the heads i Just need a list of parts that i'm gonna have to buy for this project
- take the heads to your local automotive machine shop and have them do the valve job they will fix whats wrong with your heads.and for parts you will need a head set gasket kit from auto zone or summit racing,and new spark plugs wire's oil, antifreeze,belts water pump since you have the room to get to it now,
