Q:so i'm replacing a one hole faucet, and i'm stuck at the very first step. the cold water valve turned off with no problems. i tried to turn on the cold water and none came out. unfortunately, the hot water valve just squeaks and goes around and around, never cutting off the water. when i turn it, it also leaks a minute amount of water, though regardless of which way i twist, it stops as soon as i do. i can't just unplug the hot water valve with it still running water, so does anyone have any ideas? how does one replace a valve like this to begin with? is it possible that there is a shut off valve for the house that i myself can access (without having to call someone to shut off my water)? in case you haven't noticed, i am a bit plumbing deficient, so if you could explain it without too much jargon, it would be much appreciated.

There should be a main shutoff valve to cut the entire water supply to the house. If you have a basement the main valve would be where the water supply comes into the house. 99% of the time that is in the front of the house. If you live in a slab house then the main water shutoff is usually near the hot water tank in a pipe that typically comes out of the floor. If it is not there then it will be in the yard (usually the front yard) undeneath a metal cover. You can always turn a valve off and then check water by opening a faucet. Remember that you need to give it a couple minutes to see if it has shut off fully as water may drain out of house pipes. If you are just going to replace the hot water valve then you may have a shutoff for that above the hot water tank. Most lilkely the inlet side but could be the outlet side or even both. You can try those. Now you replace the valve once you are sure that water is shut off. You may not need to drain the hot water tank. Just turn it off and see if water continues to come out. Just turn a valve off and check to see if the water shuts off. Eventually you will find the right valve. Just remember it can take a while for water to drain out of the pipes. If you need help replacing the valve just add an additional comment and I will check back. Describe to me whether you have copper pipes or galvanized pipes and the type of shutoff that is there now.

Q:Are they referring to the nozzle orifice or are they talking about the diameter of the nozzle? Does it mean the inner diameter of the valve like in a globe valve?

A 12 inch valve means it is designed to fit with nominal 12 inch pipe. Most 12 valves are flanged so these valves would also be flanged to match as 12 piping flange. They would also be sized to match the appropriate flange rating as in 125#, 250#, 150#, 300# 600# and so on. As to the opening of the valve that will vary depending on the type of valve. For a gate valve it will be very close to 12 inch in diameter. For a globe valve it may be a bit smaller. In some cases you will see what it called a reduced port valve where in internal opening is smaller. This is more common with large ball valve where the smaller ball and opening makes the opening/closing torque less. These valves also tend to have a venturi shape on the inlet and out leading to be ball so the pressure drop is closer to a full opening valve.

Q:My 10 year old boy was diagnosed with a leaking heart valve yesterday.The Doctor is trying to get him in to see a specialist asap.She didn't seem that concerned with it,but I don't know if she was just trying to keep us calm about it.How serious is this,and is surgery the only way to fix it,or do they have meds for this condition.

People with leaking heart valves usually see a cardiologist, who is a heart specialist. What they usually do is what is called an ECHO, which is a type of ultrasound of the heart. This can tell how bad the leak is.You have valves in each side of your heart, they function to help your blood flow correctly through your heart when it beats. If the heart valve is not leaking a lot, they usually monitor it with repeat ECHO's. If the leaking is such that you get short of breath, tire easily or other such things, they may recommend surgery. This is usually the only option, there is not medication that can fix the problem. If surgery is needed they will replace the valve. If surgery is needed the cardiologist will refer you to a cardiac surgeon. Ask questions. You need to see a specialist and then they can better explain all of this for you. Be heart healthy.

Q:Hi guys, Thanks for your advice. RandyK is right, my dad's GP told me that if we don't get the valve operation, his heart will swell in years time and might cause more complicated illness. Just let you know my dad had seen his cardiologists recently and had some scan or tests done. The results will be discuss in next appointment, they suggested that mechanical valve would be used if the operation go ahead. At the mean time I just hope and pray his condition will under control by medication. Wendy, may I ask you how old are you when you had your valve operation? I am too scare to suggest or encourage my dad to do the operation. Because if there is any difficulties or worse ...during operation, I will be the one send him away......If anyone have a relative like my dad's case,(76 years old had valve operation) please give me some advice.. Many thanks

A friend 65 and I , age 61, had our mitral valves replaced this year. I felt very tired at first. Barely could get up into a pickup truck. My chest felt stiff with difficulty raising my arms. I slept on a couch with 2 pillows awhile. If I laid down flat on the bed, I could not breathe comfortably. It felt so great to be able to lie down flat on the bed after about a month. I had little twinges in my chest occasionally. It has gradually gone away. After 6 months, I feel great and can do all I could do before surgery. I go to water aerobics 2 times a week and walk my dog. Many people are getting valves replaced at ages 60 and 70.

Q:can you put a blow off valve on a chevy cobalt ss supercharged?

the correct answer is yes and depending on the size it may be critical. turbos use a waste gate while blowersaka super chargers need a blow off vale to prevent to much pressure in the cylinders. causing a blown head gasket, blown intake gaskets, or even blowing the blower off the top of the engine. If you ever look at a car that is set up with a real blower on the back of the intake manifold there will be a plate held in place by two springs, that is the blow off valve.

Q:Hi i have a 00 bmw 320d and am trying to find out information on puting a dump valve in, is it possible?, what type of dump valve? and how hard it would be to put in?? any help would be much appreciated.....Thanks!!

Q:I was diagnosed by 2 places that my 1995 chevy lumina needed a new egr valve due to the check engine light being on. I got a new EGR valve but the check engine light is still on. Evidently there is something else wrong with the car. Since the check engine light is still on would you figure that my EGR valve is still good and that the light comes on for some other problem?

i think your right. I'm not sure but a think your EGR valve is vacuum operated. If so, there is a vacuum solenoid to control the vacuum to the egr valve. There is also intake vacuum to this solenoid. Could be no vacuum to solenoid or a bad solenoid or wires controlling the solenoid. But also could be a completly different problem other than egr. You need to go back to the shop that put on the egr valve and find out why the egr valve didnt fix your problem. And either have them fix it right or get your money back.

Q:I have a 2001 Chrysler 300 m. About a year ago it cut off on the interstate. The mechanic told me my timing belt broke and i had three burnt valves. The timing belt is already fixed, but I was wondering what parts were needed for the other. also what is the estimated price to fix this?

Burnt valves or, far more likely, bent valves. Either way, you'll need to basically overhaul the top end - you'll need to replace the bad valves and the top end gasket set along with any machine work that may be necessary. Estimates will vary greatly from facility to facility and also from different areas. To get a valid estimate for your locality, you need to get local estimates.

Q:HI ever one i have a 1969 1500 beetle engine i have just but 1600 piston and barrows on it but when i but the rockers on i have no valve gap at all. ive wound out the adjusters all the way and i still can not get a feeler gauge between the rocker and the valve. Please help cheers Adam

The problem could be that the crank shaft has not been turned to the place to adjust the valves. The push rods could be the wrong length ones too.

Q:whats the location of the pcv valve on on a 2001 bmw 740il (e38)

In front of the engine slightly to the left and lower area of the throttle valve. It is a round black plastic canister supported by a teardrop shaped rubber with a cable connector at the top and 2 hose connections at the opposite end of the cable connector which are perpendicular to each other. BMW calls it the tank vent valve.
