Yes, an oil well can be "shut off" by the use of a device that has a hydraulic ram that can crush and seal a pipe (or simply shut a valve) to secure a wellhead. The so-called "blowout preventer" is such a device, but in the case of the current disaster in the Gulf of Mexico, the device failed (owing to a failure to replace a battery, as one report had it).
1. Replace the pipe, 2. Shut off the water
it is defined as the pipe cemented in the well to seal off formation fluids and to keep the hole from caving in.
In every home thee are a number of shut-off valves. Where the water pipe enters the house is the main shut off, usually beside the PRV, a bell shaped device for regulating the house pressure. This main cold line will then branch off to the water heater, bathrooms and kitchen. Each faucet and the water heater and the toilet will have a shut-off valve. The hot water line comes out of the top of the heater and goes to bathrooms and kitchen. Each hot faucet also has a shut-off valve under it.
I do not know your situation but a good guess is that your well pump is always on and is not getting enough pressure to shut off the pressure switch. So I would shut off the power to your well pump and see if the buzzing stops and if it does then I would replace your well pump. If the buzzing don't stop with pump shut off then it could still be your well pump check valve slowly leaking threw but I think its your pump because its not pumping enough to shut off with or with out a bad check valve.
Locate your main water line inside house and shut the water off. Cut pipe and place a tee solder into place. Run your line to exterior of house placing a shut off inside.. Test for leaks..
the pipe is closed by a gate or ball that cuts off flow through the pipe
What to use to solder a shut off valve
On any water heater, the shut off is on the incoming cold pipe.
1. Replace the pipe, 2. Shut off the water
By soldering or brazing
Shut of the water to the faucet. If a local shut off is not present then the main house shut off will have to be used, or the cutoff at the meter. unless plastic pipe is used then the faucet screws onto the water pipe. It will probably take a pipe wrench on the pipe and the faucet to break it free. use Teflon tape to cover the pipe threads before screwing on the new faucet. Turn the water back on and check for leaks.
By a shut off valve connecting it to the main pipe to your apartment or house.
It is probably for when there's a gas leak. The room could go up in flames if there's gas everywhere and it is ignited. The emergency shut off will shut off the gas in case the knobs or a pipe is broken
Someone may have shut off the water to that faucet, or a pipe may have froze, or there may be air in the pipe.
You should pour bleach down the pipe.
You would shut off water in the last few weeks of autumn before the first frosts of winter to prevent a frozen pipe.
The cost to replace the water shut of valve varies based on if it is to a sink, toilet, hose, or the entire house as well as the type of pipe used. They can range from twenty dollars to around a hundred dollars.
