I disconnected the hot and drained the water from the connecting tube but water still came out of the shut off valve at a decent pace.I placed my finger over the valve and i felt pressure build up...like when you stick your finger over a bottle of soda.I tightened the bolt on the valve and even the screw to the handle to no resolve.any ideas on how to make it stop while i connect the Pedestal sink?also, i am as novice as it gets.thanks in advance

Answer:

You can turn the water off outside where it comes into the house. There should be a shut-off valve there. That will stop your valve from leaking until you get everything hooked back up. You can also turn it off at the meter if you want. There's a shut-off inside there too.
Your relief valve will could desire to be for tension and temperature! while water is heated it expands. a variety tank is often needed. a common significant subject and frequently neglected is a verify valve on the chilly water inlet into the water heater. besides the fact that if it particularly is in a blending valve very probably fastened or some water warmers have been given right here with warmth traps fastened on the heater. the warmth temperature capture on the chilly water inlet had a plastic marble that floated up and sealed heat to your water heater. in many situations they seal tight and did no longer permit the water out because of the fact it speeded up. in the adventure that your 2d relief valve is leaking you often have some element like this happening. a kind tank put in on the scorching water area will scientific care this. You mentioned you have became the warmth temperature all the way all the way down to ninety. have you ever used a thermometer to verify the water is in the ninety degree variety? think approximately a foul thermostat on the water heater it is over heating the water, in spite of the actuality that it is uncommon.
The valves packing (seat) is probably worn and it wont seal. Either repair of the valve is in order, rebuild. You need to shut the water main off. Most houses have a master shut off valve that kill all the water to the house. If no such valve exists, then you would need to go out to the water meter and shut the water off at the meter to kill the flow to the house. Then install and make your repairs and install your new sink. The valve repair must be done when the water is off to the house. You cant fix it with the water on.
It's not the packing nut seal since that only seals the stem which is attached to the handle. There is an inner washer attached to that stem which shuts off the water, this is probably worn and needs replacement. Do not attempt to change this valve, leave it to a professional because it's not an easy thing to do, unless you're good at soldering. Shut off the main water supply that services the whole house. Also note: If you don't have wood behind the sheet rock from your existing vanity, you'll be in trouble, because the Pedestal must be bolted to the wall to be secure otherwise it's a safety hazard.
Hi There, There should be a shutoff valve at the water meter or sometimes there will be one inside the house where the water main enters. You can shut off the water there. Another option is there will be a shutoff valve on the cold water side just before the water heater. You can shut off the water there. The shutoff valve under the sink should be replaced at your earliest convenience because they are there for a reason. That would also be a good time to replace the cold water shutoff valve under the sink also because both valves are probably the same age. New valves can be found at a home center or hardware store for a reasonable price. Note: You really should locate your main water and gas shutoff valves so you can find them in an emergency. The same goes for the main electrical shutoff. It is important to know this beforehand. Hope this helps, Al
