Q: I have three zone valves, two out of the three don't ignite the gas. Once I turn up the thermostat I see the lever on the zone valves move but no gas ignition. Only one of three works fine. Any leads? Thanks!: the zone valve will turn on the pump. if the water temp is high enough, the gas wont turn on. check the aqua stat to see the temp setting

Q: I want to make a ram pump but i don't have any waste valve. So I decided to make it but i don't know howCould you help me?If you can send me pictures, video and something like that (Pleasssssssssse): I already answered this for you, but here we go again: Why do you need to make a waste valve when you can just buy one, if you need to make a waste valve, you need tools from machine shops in order to do so. BTW, it's not allowed to repeat the same question more than three times because believe me, people will think you're annoying and will assume you have a case of OCD. In addition to that, they will likely report your questions for violation to the community guidelines. Refer to the links below for the answers and rules

Q: My mom just went to DR and will have open heart next Thursday for removal of anyerisum. She was told she has 2 heart valves instead of four. What does this mean? Is it normal?: Your mom probably has a Bicuspid aortic valve, that she was born with.. it means that the valve between her heart and the aorta has two valve leaflets instead of the usual three valve leaflets (not four) in normal people. Bicuspid aortic valve is caused by fusion of two of the three leaflets. It's a fairly common congenital condition, and is associated with a risk of aortic aneurysm (a weakening of the wall of the blood vessel which then causes ballooning of the vessel wall)...usually of the ascending aorta. All the best for her safe recovery.

Q: I think I have a bad valve steam seals because when I start the car white-grayish smoke comes out of the back of the car. When let sit for 2 or more hours start car and smoke comes out everytime. Will a valve adjusment fix the problem? Thanks: I agree with MC. If you have a leaking valve seal, it'll just be a matter of time before the other ones start leaking, if it's a high mileage engine. You might as well pull the head(s) and have all seals replaced. The kit you but has all the seals in it, not just one. You can check the valves also while the heads are off.

Q: according to my study only indurial gate valves have both rising and non rising stem through handwheel and it seems that it doesnot apply to golbe valve and globe valves are only non rising stem. i wanted to know if this is right: so non rising stem valves are usually used on only clean liquids long of stem is the same

Q: I been playing the trombone for 6 years, do you think i could learn to play the baritone easily,which baritone is easier,3 valve or 4 valve.: Some baritones have 3 valves, but the others have 4. The 3 valved ones are baritones and then the 4 valved ones are euphoniums.

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.=]: I am not sure you and your father want to know if this is hereditary. If you have say have a bicuspid valve now it is not going change any thing. You will still have norma life There are many like living normally

Q: does my 96 accord have an oriface valve or the other kind of valve? if so where is it? because im pretty sure that is the problem with my a/c not being cold at all: It uses an expansion valve inside the evaporator assembly, part 11 in the first source. If the evaporator valve is not working the compressor will be damaged - by no oil if the valve stays closed or by slugs of liquid spilling out of the evaporator if it sticks open. Fortunately, orifices and expansion valves are very reliable. I bet a standard A/C service (about $100) will get you cool again. If you do anything to disturb the refrigerant loop (trying to charge it at home, trying to change refrigerant system parts) you will only spend more... probably a lot more.

Q: ive had my yz250f for more than a year and i havent had the valves adjusted......it still starts up in under 5 kicks and rides great.......are there any signs that indicate you need your valves adjusted besides not being able to start it?: You'll hear the valves ticking. It will sound like a box of BBs clanking around in the top of the engine. Treat your engine to a valve adjustment and it will give you a long life, without any expensive engine repairs.

Q: Where do I get a electric valve with a 120 VAC coil: Cheapest okorder /... Grainger being a major supplier of parts - note the high cost of many of these because of being high temp steam and hot water under pressure and look for other choices.
