Q:Can I free up a stuck toilet shut off valve?
When valves are turned all the way in an open position they tend to get stuck. Try a heat gun but make sure you have a copper line feeding into the toilet tank, not a plastic one because it can melt. Just heat the valve for a few minutes at a time, because over heating it can damage the rubber washer inside the valve. If all fails then it has to be replaced by someone who is knowledgeable.
Q:Honda civic VX.. how many valves?
'92 Civics had single overhead cams (SOHC), so they have 8 valves. 1 intake valve and 1 exhaust valve per cylinder, so since there are 4 cylinders, that makes 8. Vehicles with dual overhead cams (DOHC) had 16, but Hondas had SOHC cams at that time. I'm really surprised how many people are saying 16. That is incorrect. I am positive. You cannot have 4 valves per cylinder (total of 16 valves) on a motor that has a single overhead cam.
Q:Has anyone ever had Aortic Stenosis Valve Disorder or known anyone who has suffered from the condition and
I was born with Aortic stenosis, I had my first Aortic valve transplant at 18 and had a human graft (donor valve) Then at 24 I had another plastic replacement valve put in as my Aortic valve was leaking.. Im now 32 and it looks shortly I'll need another heart op.. I have lived a full life in between heart ops and though I have rules I must follow as I take blood thinners for life now (due to plastic valve) I'm greatful for the improved quality of life and the additional length my great doctors have given me.. I take each day as a gift! Good luck with your recovery time if you do need surgery, it is a tough ride but its well worth living after all yr hard work! Yr most welcome to Email me if you need an ear or word definitions, some days its like the doctors speak gobble ****! hee.. And it can be quite daunting wen they give you a load of information..

Q:Trumpet valve stuck upright?
on the top of the valve there is the screw that you turn to open the valve to oil it. if this screw wont turn gently tap the edges of it with the rim of your mouthpiece, and make sure that you get the entire screw cap. if this doesn't loosen it enough to remove the cap, then repeat while hitting it at an angle in the direction that it needs to turn. if this doesn't work take off the bottom cap and drip valve oil up though the bottom to drip up to the top cap and continue with the tapping process. if it still wont move, you need to take it to a shop. once the upper cap is loose, the valve still wont move, this is when you take off the bottom valve cap (if you haven't already) and fully remove a different valve that has already been oiled and push it up through the bottom of the stuck valve, this might be hard to do, and you might need to put in a lot of valve oil into the bottom to get it to move. once this valve is removed, thoroughly clean the valve casing and the valve itself, and oil both before replacing the valve. Hope this helps.
Q:water inlet pressure relief valve?
It sounds like a cold water relief valve, also known as a thermal expansion valve. It leaks when your city pressure exceeds 100psi (factory setting) or the set pressure. Code requires pressure to be below 80 psi. A Watts 530C will do the trick. It is adjustable. It will cost you about $30.00 - $40.00 + labor to remove old install new. If it is a pressure reducing valve, a new one will cost about $125.00. It lowers your pressure when it exceeds max allowable per the plumbing code, 80 psi here in Florida. I use the Watts 1 25AUB-Z3 Pressure Reducing Valve for these applications and set it at 60 psi.
Q:aortic valve with 98% gradient can be cured by body revive?
Can be cured by valve replacement... alternatively, if you can't/won't go through open heart surgery then you may be able to get valvuloplasty. A balloon is used to stretch the valve open. This does not last nearly as long as replacement, but avoids surgery. A third alternative would be to contact one of the percutaneous valve REPLACEMENT centers (Mayo, Cleveland Clinic, Columbia). This is an experimental procedure which replaces the valve using catheters instead of surgery. Advice offered here is not meant to be a replacement for proper evaluation and examination by a qualified medical professional and should not be construed as such.
Q:reed valves on a 1999 yz 250?
the aggregate is slightly skinny. The exhaust will smoke much less, however the appropriate end will ware quicker then standard. replace the piston rings as quickly as a 12 months could shop the engine risk-free.
