Question:

replacing a faucet, but i have a broken hot water valve?

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.

Answer:

You do not need to empty the water heater. Just shut off a valve at the heater and that will shut off all the hot water in your home. Do not empty water heater. I would also recommend a new shut off valve for the future.
There has to be a main shutoff in the house, whether you are hooked up to city water or have a pump. And no, when you shut off the main valve and the pressure drops very little more water will escape the water heater. If the water heater has a shut off valve on the hot water line coming out of it, even better. Shut one or the other/or both off and drain the pressure via the sink faucet. The only water you will get when you take the problem valve off will simply what is in the lines. You can then change the valve and faucet. It's always prudent to shut off the power, or flame if the the water heater is gas, in case there is a bit of syphoning.
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.
i assume my first questions could be did you pay him? Then, How? Then, Why? Is he a corporation proprietor, worker of a significant or usual plumbing comapny? Did you examine even if if or no longer the plumber or his comapny grew to become into approved, bonded, insured? For that plenty money, if no one will ensure the difficulty, small claims court docket could be my next call, then the BBB, then the community chamber of commerce alerting all and sundry of the region. i've got self assurance i might flow so a ways as to examine the fee, and what it breaks down into (no pun), then finally I might desire to ask, as this might have been an emergency restore, DID YOU get a written estimate prematurely, or a minimum of attempt to get multiple estimates. by way of fact the buyer rather you have rights, yet you besides mght have some logical household initiatives besides, IE: understanding a minimum of a few ballpark discern up front, earlier the plumber, or any trades guy or woman opens a gadget field. If any of my above questions relate, and the plumber works for a organization, i've got self assurance if it grew to become into me, i could be on the telephone and of their face at present, and loudly. previous which you prefer no longer even threaten regulation tournament,,,you will possibly be as professional as you state the plumber grew to become into, and seek for suggestion, checklist/rfile each thing that transpires, then get an atty.
