Q:Around the relief valve there is water leaking it is not the valve it's self or the threads it's around the out side of it. The valve is on top of the heater
close off the chilly water grant to the water heater and additionally close the gas grant or the heater administration. Drain the water heater (this might drain all your homestead warm water besides). Open a warm water sink valve to enable air enter. Drain the water till the water is below the threads. decrease or unsolder the joints mandatory to get rid of the threaded setting up. get rid of the setting up, and positioned across it to a community plumbing grant homestead and get a clean one. set up the hot one with teflon tape. close the sink warm valve. Open the chilly water grant valve on the water heater slowly. verify for any leaks. If its leaking, initiate over. If not resolder the copper joints jointly, and be confident to purge the air by way of your sink back. or in basic terms call a plumber or an HVAC business company.
Q:Is it hereditary? My dad had a bicuspid valve and we got told it was hereditary but some doctors say it's not, my parents wanted to get me tested in case i had it so we would know in advance but the doctors here refuse to do it (I live in England if that makes a difference) my dad said he would pay to go private if it's hereditary. I know someone who had a bicuspid valve and 3 out of her 4 children inherited it, i know it's pretty harmless until i reach an older age but my parents and i would like to know now, i'm 13 by the way.=]
About 1-2% of the population have bicuspid aortic valves, although the condition is nearly twice as common in males. It is more common than any other congenital cardiac anomaly. Bicuspid aortic valve has been found to be an inheritable condition, with a demonstrated association with Notch 1. Familial clustering as well as isolated valve defects have been documented. The incidence of bicuspid aortic valve can be as high as 10% in families affected with the valve problem. Other congental heart defects are associated with bicuspid aortic valve at various frequencies.(Wikipedia) The cause of this problem is unclear, but it is the most common congenital heart disease. It often runs in families.(MedlinePlus)
Q:in engines otto cycle
short answer more horse power.
Q:The water inlet valve on my Kenmore washer leaks. Is there an easy way to replace it? Last time it broke they charged me over $100 to fix it.
YES okorder when you get there you will need your numerical model number that you will find by lifting the lid of the washer looking down and toward the back of the machine just under the lid where its hinged. Once you type in the model number do a word search by typing in valve. It will give you a numerical part number that you can call your local service company with and get a price. Or you can usually call any service dept local with your model and they can look it up for you and sell you the part. Good luck...
Q:Full Bore ball vale and Reduce bore ball valve have diferent with each other ,I want to know about them.
Ok, so, a Full Bore (Full Port) ball valve basically will have the same size bore opening as the pipe connection. For example, if you have a 2 ball valve connected to a 2 pipeline, a full-port (full bore) ball valve will also have a 2 opening. This allows for the maximum flow of the media being processed through the valve. Conversely, a reduced bore (standard port) ball valve, will restrict the flow of the media passing through the valve. If you looked through the valve opening, you will actually see the bore of the ball is smaller in diameter than the rest of the valve itself.
Q:about a year ago a bought a bach stradivarious. the valves aren't sticking, but they are still considerably slower than my ten year old omega. shouldn't they be broken in by now? i've cleaned it countless times and tried many different valve oils. any tips on how to get them faster? thanks to all!!! :)
Despite okorder and ask for recommendations based upon your location. It's a good bunch of guys who will steer you in the right direction.
Q:I have tried to adjust valves of Suzuki Intruder VS400 but they still tapping..so how to adjust them in the right way?
if okorder and download the free bee manual for your bike.
Q:what are the factors should be know to select a control valve for specified application
nan
Q:I want to switch off the water in the bathroom only due to replacing sink taps, will water still come out of the pipe if i turn the stop valve
Only water what is still in the pipes will come out but you will lose all your hot water in the hot water cistern if you have that type of hot water storage tank.
Q:I have an '03 vw jetta and don't know if I should get a greddy blow off valve or an injen cold air intake? Any suggestions? I don't know a lot about either, what is the difference between them?
the better More reasonable choice is the cold air intake but beware if you buy one make sure it is not some cheap imitation because it will be a waste of money because it wont work properly of allowing colder air into the engine rather than sitting on top of the engine doing nothing.
