Which way to turn valve knob to close?

On a round valve handle you normally turn it clockwise to close .


How do you get a propane tank knob unstuck?

A common mistake is assuming that the tank valve (to which the knob is attached) is closed. It may be already open to the maximum, which means that trying to turn the knob counterclockwise to "open" the valve to let the gas flow to the appliance is not possible. Forcing the knob in any way will usually result in breaking the metal at the base of the knob, rendering the knob useless. Before trying to turn the knob counterclockwise, try turning it clockwise to make sure the valve has not been fully opened. Use a cloth wrapped around the knob and slip joint pliers to gently push the knob. Don't use excessive force or you may damage the knob. If you are sure that the valve is closed, but can't be turned counterclockwise, use a penetrating oil, applying liberally at the point where the valve/knob shaft goes into the valve. Keep the tank upright and wait 15 to 20 minutes before attempting to turn the knob again. If all this fails, you may be forced to have a propane expert replace the valve and knob, or buy a new complete tank.


Where is the knob to turn off your water from the street?

If you have a basement, it will be on the basement wall closest to the street. If you are on a slab, it is most likely next to the water heater. There will be a water meter between the house and the street, there should be a valve there, but it may need a shaped key to turn it and they can be tight.


Does water pressure need to build up after you turn the water valve off because you had half the water pressure you did when you turned the water valve back on to your sink?

No, water pressure is immediate. If you replaced the sink faucet you probably ended up with one of the "low flow" faucets that are being produced to save water. Sometimes they can be taken apart and "encouraged" to let more water through. if the valve had no been used in awile the gasket will stick when you turn it off and back on replace the valve with a quarter turn ball type valve and you wont have this problem again

How do you do a hot water system check?

Turn off the hot water to your tank and do not use any water -- and leave it off for about 30 min. -- then turn your valve back on and if you hear water going back into tank you have a leak somewhere


Why would the hot water valve suddenly shut off the flow of water When you close it and open it again it is fine This happens mostly when the dishwasher calls for water?

could be a lack of pressure, or a lime blockage in the seat of the valve, turn water off to valve, remove the stem, turn water on then back off, this might clear any blockage,


Is it normal for water shutoff valves for the sink to leak when trying to turn the water off?

No, the nut on the valve needs to be tighten. When you turn off your faucet, pressure in the line is increased and the seal in the valve is not tight enought to hold back the water. The brass or nylon coupling in the water shutoff valve may also be damaged and need to be replaced.


My backwash pool valve will not fully close. Can pine needles get inside?

Mine did the same. The rubber gasket under the valve knob had become messed up. I unscrewed the valve and put the gasket back in place. My local pool place says this happens alot when you turn the valve from backwash to filter while the pump is running.


Why would there be no water at all to the whole house after the county comes and replaces the entire main check valve and say everything is good on their end?

Did the main water valve get turned back on? They obviously failed to turn your water back on. Call them and complain until they get it right.
