Q: My water faucet has a male thread at its outlet. I am trying to determine the thread size and type so I can order some fittings.

Q: We all know that in the slowly open the faucet, the water is obviously slow, and then slowly all the faucet flail gnome gypsum pork chulan open, the water flow faster and faster, more and more, But we have played such a game, the faucet by the water pipe, pinch the other end of the water pipe, let go of a small mouth, the speed is not very fast, the solution is also a small export, why the difference between before and after so big? More: Ask well! water pressure before the leader and the water pressure in the water pipe is the same, the water speed even so much difference! Water in the water pipe is through the small slit "straight" rushed out, no other additional resistance. When the faucet is very small, the water is also through the small slit out of the flow, but that small seam is "horizontal", the water at least around the second bend, which brings a considerable resistance around the bend, so the water slow down , And even a drop of the.

Q: Faucet water is very small, a little blocked, how to do: Remove the faucet for one, close the total valve

Q: I'm having a problem with my 35154678 year old bathroom faucet.Leaking has always been a slight problem but I've always somehow been able to get it to stop if I close the faucet REALLY tightly. However, today I tried to turn the faucet shut, and the thing just popped and doesn't stop turning! It goes around and around from weak water flow to strong water flow, without the usual "resistance" before the water finally stops. So basically, I can't shut off the water flow by using the usual faucets and I have to use the main faucets underneath the sink.Gee, I sure hope I'm making sense.I guess it is time for a replacement, but can anyone tell me what might have broken to cause this? Will repairing this be as easy as simply replacing the O-rings, or do I need a plumber?: It's best to just replace old faucets. Modern technology offers far superior valving than what you have. Call a plumber. Most plumbers will give you low cost or free estimate to repair or replace it and have enough experience to recommend what is best. Older faucets sometimes can be very difficult to replace, best to save your knunckles and let a pro take care of it. Avoid cheap faucets, ones that are made in Mexico or China. Expect to pay at least $ 100 for a good faucet. Good luck.

Is there a problem with the pipeline? More: Strange! 1, for the faucet is willing to be the top of the problem, (regardless of Gong Department of Feng Yi Yi Yi Seng sail line is how to pick up, in the case of the faucet is closed can not have the phenomenon of water) 2, for the open one, the other one Close to the water, it is necessary to consider whether there is a pipeline in the installation of defective place.

Q: Why is the bottle of water leakage, and the water bottle is not bad ah: Because the mouth did not close up, do not thank

Q: Is it hard to change the faucet and handles on a sink? I just bought a house and its a new sink.: if its a new installation it should be easy. you need a basin wrench, two 3/8 inch x 20 inch flexible steel braided faucet supply's, the new faucet and a flashlight. put down some rags under the sink (gets a little wet) close the valves under the sink and turn on the faucet to assure they are off and holding. remove the supply lines from the faucet and the valves you closed under the the sink. now loosen the capture nuts on the shanks of the faucet where the supply's were removed. after the captures are loose and removed the faucet lifts up and away. if there is a sprayer to the right of the faucet just cut the hose and remove it. the new faucet will come with installation instructions and pictures...so i won't have to write a novel here. if you get a basic faucet it will be simple... when you get into the exotics it becomes a strain. stay with a delta or a moen faucet...stay away from price phister...remember when you are purchasing a faucet... if there is an existing sprayer to the right of the faucet you will need to buy one with a sprayer (w/spray) don't want a sprayer and one exists...you will need a cock hole cover for it. talk to a sales person at a plumbing supply house....stay away from home improvement centers...best advise i can give you and good luck to you. yes there is a price dif between the supply house and home improv center...but you tell the guy at the counter in the supply house about it and many times you get a break. PLUS they know their product. good luck
