Q: We just got a new washer and cannot remove the old hoses from the pipes with the shut off valves on them. I don't want to bend or break anything. any suggestions?: Renpen is correct, but after squirting some WD-40, I would tap it all over with a 7/8 box end wrench ( a big one) and that way loosten the crud that is keeping it from unscrewing and replace them with stainless, flexible hoses.

Q: 1990 Pontiac Sunbird 2.0L Fuel Injected has EGR Valve, I can suck and blow through the hose connected to it, an I supposed to be able to do this, or not...? It looks old, like it's been on the car forever...: It recirculates the fumes and the air--but a cracked hose is a nightmare if vacuum leak develops--fix it--just get a new hose and happy motoring

Q: So i finaly got my check valve and my airstone. The airstone is actually a flat round airstone and is 5 inches in diameter to be in my 10gallon. Is it to big? though i have a tetra whisper air pump for 10-30g.And how do i place the check valve? Do i put it closer to the tank or closer to the pump? (just to make sure since i heard so many different ways people put it). Or does it even matter?And lastly, do i put the OUT side of the check valve facing towards the tank or the pump?Thanks! after this im ready to install it!: Adequate the purpose you let a tank cycle in the first place is due to the fact of Bactria needs to grow that will maintain your water clear. As for overstocked. I consider your proper on the threshold of being over stocked. Just preserve the tank walking a lil longer and spot if it clears up. But when your 15 gallon tank has the filter from the ten gallon tank that could be why to you dont have sufficient water moving around to scrub it

Q: I want to change a stuck pcv valve on my 86 toyota pickup 22RE. I've used tons of lube and picked away at the grommet but i still can't get it out. Any advice?: It is mounted in the valve cover if my memory serves me right.There may possibly be a clip on the inside of the cover holding the valve in. I am thinking the reason is because if it's time to change the PVC valve, it's also probably time to change the valve cover gasket. I would pull the valve cover off, change the valve, replace the gasket on the valve cover and reinstall. Makes a simple job really long but you never know what the engineers of cars had in mind!!

Q: My valve cover gasket has less them 2k miles on it and i noticed in some areas there is a lil oil shine around it so i was thinkin maybe i have to retighten the valve cover a lil bit more?: maybe so.some valve covers have stops built in to keep you from overtightening and cutting the gasket,some dont.if you used silicone,and it didnt set up,youll never hold it now.

Q: Offcourse temp control valve controls temp, and pressure control valve controls pressure....and so on. I am wondering, what are the mechnical differences in the valves body and how are they operated in terms of process control.: In principle all valves are flow control valves. What changes is the variable they are controlling. A temperature control valve controls a flow to heat or cool another fluid. A pressure control valve, controls a flow to maintain the pressure in a vessel. As pointed earlier, valves can be self contained, i.e., the sensor is part of the control mechanism, usually a diaprhagm which moves the valve stem. and a spring to adjust a set point. Or, they can be pneumatic or electronic, in which case there is an external power source, transducer and controller to adjust set point, gain, reset and rate. This gives additional flexibility, if needed, depending on the process to be controlled. .

Q: How come my boiler supply valve isnt letting water into my boiler, i have a cold water supply hooked up to it with the valve on i have tested the copper pipe goin into it and water flows into it, but when It reaches the valve it stops. I understand that it my have a backflow preventer in it and I am wondering if that could be malfunctioning. The hole you see on the front is where my expansion tank screws in. Also where could I get a new Valve. Thanks.http://img149.imageshack.us/i/boilerfillvalve.jpg/: I work on antique steam boilers and engines for a hobby and if your supply valve isn't letting feedwater into the boiler, I'm going to tell you right now that you potentially have a VERY dangerous situation on your hands. Until you get this issue resolved, I would recommend that you not steam this boiler up under any circumstances, unless you have a backup feedwater delivery system that is working correctly. Many people don't know this, but a low water condition in a boiler under steam is essentially a ticking time bomb and can result in a fatal explosion. As to what may be causing it, I would say it's possibly one of two things: 1.) The check valve has been installed backwards and the flow of water is basically pushing it shut. 2.) The check valve is installed correctly, but is frozen shut due to corrosion and scale. Either way, I would have a certified boiler inspector come out and take a look at it; he can probably tell you more than I can.

Q: It has been known that although tissue valves have lower rates of thrombotic episodescompared with mechanical valves, they are difficult to procure, and their longevity has not yet been proven. Is this true as of 2007? Thanks for answering.: Aortic valve alternative is a surgery wherein a affected person's aortic valve is replaced by a distinctive valve. The aortic valve could properly be stricken by a extensive selection illnesses and require aortic valve alternative. The valve can the two grow to be leaky (regurgitant or inadequate) or caught partly close (stenotic). Aortic valve alternative presently demands open heart surgical operation. learn is being achieved now directly to advance valves that is implanted utilising a catheter without open heart surgical operation. There are 2 uncomplicated varieties of synthetic heart valve, mechanical valves and tissue valves. Tissue heart valves are many times produced from animal tissues, the two animal heart valve tissue or animal pericardial tissue. The tissue is dealt with to avert rejection and to avert calcification. there are possibilities to animal tissue valves. on occasion a human aortic valve could properly be implanted. those are stated as homografts. Homograft valves are donated by sufferers and harvested after the affected person expires. the sturdiness of homograft valves is probable the comparable for porcine tissue valves. yet another technique for aortic valve alternative is the Ross technique or pulmonary autograft. The Ross technique includes going to surgical operation to have the aortic valve bumped off and changing it with the affected person's own pulmonary valve. A pulmonary homograft (a pulmonary valve taken from a cadaver) is then used to swap the sufferers own pulmonary valve. Mitral regurgitation (MR), additionally conventional as mitral insufficiency, is the strange leaking of blood interior the path of the mitral valve, from the left ventricle into the left atrium of the middle.

Q: My doctor detectd a heart mumer. I am 48 years old. Had a echocardiogram performed. He says that I have a sightly irregular valve and I do not need to take precautions. I run three miles a day. I have heard that this condition makes your heart more suceptiable to infection. You should take antibiotics when dental work is done. My GP is a man of few words. Just says continue as usual and nothing needs to be done unless there is further symptomns. My question: Should I follow up with a heart specialist or would it be over doing it? Should I go on antibiotics when I get dental work? Can this Slightely irregular valve get worse?: Hi not much help but i am a 26 year old female, My doc also found a mumer and then a leaking valve,said there was no need to worry this would never be a problem,but i have a history of heart disease and hypertension so I am getting a second opinion you know your body best get one to if you are concerned! Wish you the best, glad to hear i was not the only one told not to worry.

Q: My brother is 32 years old.He has an enlarged heart ,a murmur,high blood pressure and heart regurgitation.He may be having the valve replacement surgery.I was wondering if anyone has had these things wrong with them and had the valve surgery and did well afterwards.Any information would be very much appreciated.: Which valve is getting replaced (there are 4 in the heart)? Will he be getting a man made one (which will require life long blood thinners but are also very durable) or a pig valve (no need for blood thinners but won't last as long) ? Many people get valve replacements and it makes them feel wonderful afterwards.... make sure you find out about exactly the surgery he's having so you know... but I'm sure he'll be fine.
