Q:Valve replacement surgery?
A friend 65 and I , age 61, had our mitral valves replaced this year. I felt very tired at first. Barely could get up into a pickup truck. My chest felt stiff with difficulty raising my arms. I slept on a couch with 2 pillows awhile. If I laid down flat on the bed, I could not breathe comfortably. It felt so great to be able to lie down flat on the bed after about a month. I had little twinges in my chest occasionally. It has gradually gone away. After 6 months, I feel great and can do all I could do before surgery. I go to water aerobics 2 times a week and walk my dog. Many people are getting valves replaced at ages 60 and 70.
Q:how to loosen a ball valve?
If what you have is a KBI plastic valve used commonly in PVC water pipe systems, you are stuck with a stiff valve. The best and only medicine for them is to open and close them frequently. Hard water deposits will cause them to work harder as well. If, and when you replace, useing a little petroleum jelly on the ball portion before installation might help, but I’m sure the manufacturer would frown on this. They can operate so hard that the handle will break off, so if you can turn it on and off, just keep working it.
Q:Where can I buy a snorkel purge valve?
try amazon and OKorder
Q:yamaha warrior valve adjustment?
The link below shows what the valves are. The adjustment to them requires loosening #13, and then turning #12 such that the valves #1 2 are within the proper specification. To do this requires disassembly, then measurement and adjustment, and finally reassembly. This can range from 1.5 to 3 hours depending on various reasons. So, estimate 3 x [Labor Rate], whereas [Labor Rate]s vary from shop to shop, and I've seen from $65 to $120.

Q:Who knows anything about a leaking heart valve?
You have not stated which valve is leaking. Most probably Valve complaints are due to mitral valve and/or aortic valve. Heart valves are damaged due to rheumatic fever. Mitral stenosis (MS) is narrowing of the mitral orifice impeding blood flow from the left atrium to the left ventricle. The (almost) invariable cause is rheumatic fever. Common complications are pulmonary hypertension, atrial fibrillation, and thromboembolism. Symptoms are those of heart failure; signs include an opening snap and a diastolic murmur. Diagnosis is by physical examination and echocardiography. Prognosis is good. Medical treatment includes diuretics, β-blockers or rate-limiting Ca channel blockers, and anticoagulants; effective treatment for more severe disease consists of balloon valvotomy, surgical commissurotomy, or valve replacement. Mitral regurgitation (MR) is incompetency of the mitral valve causing flow from the left ventricle (LV) into the left atrium during systole. Common causes include mitral valve prolapse, ischemic papillary muscle dysfunction, rheumatic fever, and annular dilation secondary to LV systolic dysfunction and dilation. Complications include progressive heart failure, arrhythmias, and endocarditis. Symptoms and signs include palpitations, dyspnea, and a holosystolic apical murmur. Diagnosis is by physical examination and echocardiography. Prognosis depends on LV function and severity and duration of MR. Patients with mild, asymptomatic MR may be monitored, but progressive or symptomatic MR requires mitral valve repair or replacement.
Q:Sprinkler valve leak?
You are turning on electric valves, manually, with the bleeder valve (little black twisty thing). It is normal for this to happen. This valve can turn on and off a zone, but it also releases air from within the lines causing water to spit out with it. After the air is out, you can twist it down enough to stop the leak and still have that zone remain on.
Q:What does dropping a valve seat mean?
Valve seat is the actual area on the head that the valve rests in when closed. Dropping a valve normally means that the keepers have come loose or a spring has broken and the valve has dropped into the cylinder. This was a common occurance when some one has modified an engine without upgrading the valve train especially in older engines.
Q:valve clearance?
289 bored to 351? Maybe possible to STROKE it to 351, but I've never heard of it. I have heard of people running that much lift with stock springs, but I wouldn't recommend it. It's easier to change the springs with the heads off, so you might as well pull them and check clearances with clay.
Q:Painting valve cover?
if i were you i would replace the gasket ! even if it don,t break taking it off it,s best to put a new gasket on when you pull the valve pan !
