Q: I am replacing my vanity sink with a Pedestal sink. I turned the shut off vales to the off position tight.I disconnected the cold water and drained the remaining water and everything was fine. I disconnected the hot and drained the water from the connecting tube but water still came out of the shut off valve at a decent pace.I placed my finger over the valve and i felt pressure build up...like when you stick your finger over a bottle of soda.I tightened the bolt on the valve and even the screw to the handle to no resolve.any ideas on how to make it stop while i connect the Pedestal sink?also, i am as novice as it gets.thanks in advance
Hi There, There should be a shutoff valve at the water meter or sometimes there will be one inside the house where the water main enters. You can shut off the water there. Another option is there will be a shutoff valve on the cold water side just before the water heater. You can shut off the water there. The shutoff valve under the sink should be replaced at your earliest convenience because they are there for a reason. That would also be a good time to replace the cold water shutoff valve under the sink also because both valves are probably the same age. New valves can be found at a home center or hardware store for a reasonable price. Note: You really should locate your main water and gas shutoff valves so you can find them in an emergency. The same goes for the main electrical shutoff. It is important to know this beforehand. Hope this helps, Al
Q: what does mild sclerosis of aortic valve means? Why does it happens and what is its curethanks
Sclerosis means hardening. Aortic sclerosis, a degenerative aortic valve disease with thickening of aortic valve structures by fibrosis and calcification initially without causing significant obstruction, is the most common cause of AS in elderly patients. Over years, aortic sclerosis progresses to stenosis in as many as 15% of patients. Aortic sclerosis resembles atherosclerosis, with deposition of lipoproteins, active inflammation, and calcification of the valves; risk factors are similar. Aortic stenosis is the narrowing or obstruction of the heart's aortic valve, which prevents it from opening properly and blocks the flow of blood from the left lower chamber of the heart to the aorta. The aorta is the main artery leaving the heart. Aortic insufficiency is a heart valve disease in which the aortic valve weakens or balloons, preventing the valve from closing tightly. This leads to backward flow of blood from the aorta (the largest blood vessel) into the left ventricle (the left lower chamber of the heart). Causes of increased afterload that can cause LVH include aortic stenosis, aortic insufficiency, and hypertension. Primary disease of the muscle of the heart that cause LVH are known as hypertrophic cardiomyopathies, which can lead into heart failure.
Q: I have a stainless valve I want to install in a copper domestic water line. My concern is: are the two metals compatible? Are stainless steel and galvanized steel compatible?
I presume you have a threaded ss valve. It can be connected to a galvanized threaded pipe or threaded fitting. The ss valve can also be connected to copper pipe by using a male x sweat brass adapter (threaded one end, plain for soldering on the other). Brass will prevent problems from electrolysis. On threaded joints use teflon tape, or in the case where the pipe carries fuel oil, use pipe dope.
Q: What is the purpose of the LNG Vs Propane Valve that has to be installed on Gas Stoves/Ovens before use ? How can I set it myself for Propane ? What negligible effects would I experience if I hook a stove up to Propane while the valve is set-up for LNG ?Thank You !
the reason for the difference in orifice size is pressure, not btu! propane is highly pressurized and uses a smaller jet. they use the same burners, so change the jets,, it is usually easy unless you have one of those that require a special tool,,
Q: Is there any application usuage of ball valve in comparison,most engineers opinion is as Valve size get reduces in reduced port.Other than this what paramteres decides in selection of either of one

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?
Stuck Pcv Valve
Q: As title.What's an easy way to remember: mitral valve leaflets are anterior and posterior leaflets; tricuspid leaflets are anterior, posterior, and septal (medial); aortic valve leaflets are left, right, posterior leaflets; pulmonary valve leaflets are left, right, anterior leaflets?It's easy to remember all but one valve (mitral) have three leaflets each. Physically aortic root sits behind pulmonary trunk, I guess that makes it easy to remember aortic valve has left, right, Posterior; and that pulmonary valve has left, right, anterior leaflets. Where I'm running out of ideas now is how to remember tricuspid has anterior, posterior and septal leaflets... Please help.Thanks.
The tricuspid valve has three leaflets which are thin and membranous with commissures that appear more like indentations than true commissures. The TV apparatus is similar to the mitral valve but has greater variability and thinner leaflets. The three leaflets are the anterior, septal and posterior leaflets, with the anterior and septal being larger than the posterior leaflet. TV= tricuspid valve tri-cuspid=3(three leaflets) leaflets=3leaflets Tricuspid: Having three flaps or cusps. The valve that is called the tricuspid valve is situated between the right atrium and right ventricle and permits blood to flow only from the atrium into the ventricle. The aortic valve in the heart also has three cusps. Tricuspid valve (Anat.), the valve, consisting of three triangular membranous flaps, at the opening of the right auricle into the right ventricle in the heart of most mammals; -- sometimes called the tricuspid valves, each flap being regarded as a valve. Take care as always
Q: My husband just found out that one of the heart valves is 100% blocked and the other 3 are 90% or more blocked . He is 78 years old he Is nearly non mobile. What kind of treatment would you suggest?
A heart valve can't be 100% blocked. The heart simply couldn't function. On the other hand, coronary arteries can be blocked as you described. Normally, 4 vessel disease is treated with bypass surgery. In a high risk patient, angioplasty might be an option. However, if he is not having cardiac symptoms , or if he is thought to be TOO high risk, the option is medical treatment. Sit down for a talk with his cardiologist.
Q: My car (RWD) has vacuum leak and has the code PO171/PO174. I find some engine oil at the bolt well of the valve cover on the bank 2 side. Can the vacuum leak come from the valve cover? What is the main function of the valve cover? Thanks.
there is no vacuum in the valve cover. the vacuum is in the intake the valve cover is leaking oil. the valve cover covers the rocker arms.
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.
