a gate valve is a positive shut off valve for liquids and gases and should only be used in the fully open or closed positions, different temperatures and pressures must be considered to insure the correct type of valve to install. a sluice valve is a non-positive shut off valve used for heavier materials such as stone,grain,sand,etc.
How do you determine a water leak in home?
So you opened your mail, and got the water bill is much higher than it is supposed to be. You have called the water company hoping it was a mistake, but they said it is not. Perhaps they send someone out to make sure the meter is working properly, but it is. You have not seen any sign of water around your house. You have not wasted three times your normal water usage filling the pool over and over again or watering your lawn non-stop, so what is happening? Check the toilets and sinks in your house, and if you can't find another cause for the increase, you may have a water leak. If the water company comes out, they will look at your meter, and they may tell you that a leak indicator on the top of the meter may be spinning away. this is a classic indication of a water leak and often a slab leak. There are several different type of slab leaks. The service line of your home runs from the water meter to the shut-off valve in your house. If you close the shut off valve in your house, the leak indicator on top of the water meter will continue to spin. If you have a leak in your home between the shut-off valve and and of the water fixtures in your house, when you close the shut-off valve, the leak indicator will stop also. If the leak is on the service line, there is still a chance, even if you don't see water in your yard, that the leak on the line could be outside of your slab. This is most likely in climates where freezing is an issue as service lines are often required to be 36-48 inches under ground, and that depth can allow even significant water loss to dissipate before reaching the surface. In areas where freezing is not a concern, lines are often run much closer to the surface, and leaks on the service line outside of your slab are more readily apparent. Never fear!! Once you realize that you have a leak, you know what the problem is and can get started on the path to getting it fixed.
What is the difference between gatevalve and glaobe valve?
A gate valve raises and lowers a flat piece of metal, usually brass across the opening of the line it is in. A globe valve has a round ball in it with a hole through it. When open, the hole is in line with the line it is in. When closed, the hole is across the line blocking it.ActuallyA globe valve is used for throttling and is not considered a positive shut off.A gate valve is designed to be either fully open then a 1/4 turn back (to prevent the stem from seizing ) Or fully closedThis is the reason a globe pattern type is used for taps, ,bibs, faucets, and shower body'sAlso a globe valve offers the most resistance (friction).One different advantage of a globe is it ability to balance where high pressure is a concern such as a BY - PASS on a fire stand pipe system or high pressure steam applications 125 #

You just fix the flapper now there no water in tank why?
You shut the water off and the fill valve is the type that is in the corner of the tank and the float rides up and down on a shaft? If so, a piece of rust or mineral is plugging the valve. Shut the water off, hold the shaft of the fill valve and twist the top 1/8 turn counter clockwise. The top will come off and where it separates, there is a black washer with a small rod in the center of it. Take the washer out and slightly turn on the water. This will flush out any particles in the line. Shut the water off, replace the washer and put the top back on. This should fix the problem.
Why does no water come through to the toilet and it will not flush?
In the tank, if you have the type of fill valve that the float rides up and down on a tube or square shaft, there is a quarter size washer in it that hardens and will not let the water in. It is either in the top or bottom depending on the exact type of valve. Shut the water off at the wall and this type comes apart by twisting it one quarter turn counter clockwise. The washer should be at the point the float separates from the base.If you have the type that has the float ball on the rod, the valve can corrode and will need to be replaced.Sometimes, the washer in the shut off valve will come off and plug the valve. Doesn't happen that often, but something to consider.

Why does the water stop flowing in a new faucet after a few minutes?
I have seen this type of thing happen when there is a bit of junk in a line that falls back when the flow has stopped, and then move back with the flow to stop it when it gets to a point where the water is restricted. More often, I have seen it to be just something odd about the faucet making it creep off from the flow of the water going through it.
