Q:how can I buy a useful ball valve??
Hi here in the united kingdom the only place you would find a ball valve is in a tank like a header tank in the loft or in a toilet. then it would be a low pressure one or a high pressure one. what you have described sounds more like a stopcock which is a tap to switch off the main water supply to the property. which you should consult the water company about as it maybe there responsibility. so i would consult with them first.
Q:How can I fix my noisy tuba valves?
right this is what I did My truck is 2003 GMC sierra with approximately 112.000 miles that develpoed a noisy lifter. I asked around and offered a prior employer tip. This truck has the vortec 5.3 which I easily have study different posts that those autos tend to boost this equivalent style challenge. Pour a pair of quart of gas into your oil,particular I stated gas, run for 30-40 5 seconds. close off the motor this would possibly not restoration the challenge yet. . upload one extra quart of gas, permit it run 30-40 5 seconds close off the motor. permit stand 40 5 minutes to an hour The gas will injury down the gunk like no diverse. Drain oil and eliminate the filter out. What I did next replace into as quickly as positioned the oil plug in purely and added a pair of a million/2 of gallon of the pink potential degreaser down the hatch and permit that sit down for a stable hour. Then I drained it and guy did some nasty stuff come out. With the plug out I dumped one extra quart of gas down the hatch lower back to flush it. eliminate cap, dipstick and shelter the plug out and permit it breath for a staggering hour I switched to Valvoline synthetic mixture 5w-20 from pennzoil classic 5w-30 and have been given a wix filter out from a puralator. I stay in florida so I are actually not finding for the better weight oil. positioned the pug and filter out in, introduced the oil and ran the engine, in no longer as much as 30 seconds the noise replace into as quickly as long previous. I permit it run for slightly, close it down, then began the engine as quickly as extra in all probability 3 hours later The motor is whisper quiet, It hasn't run this quiet in years. wish this enables. i'm no longer particular if this attitude would artwork on diverse engines so use your judgement
Q:pcv valve?
THE GUY ABOVE TOTALLY MISSED IT. IT IS VERY SIMPLE TO REPLACE AND SHOULD COST LESS THAN $25.00.
Q:My second valve on my French horn is coming up slowly?
Try oiling the top and bottom bearing. One is located under the valve cap, at the top of that stem. You can see it turn when you move the valve. Put a few drops there and then move it. For the bottom bearing you need to turn the horn over and put some oil in the crack where the valve comes out of the valve case, under the string area. Again, oil it and let the oil get in while you move the valve.
Q:pool and spa valve diagrams?
You have one or more faulty valves or you've got them turned the wrong way for the operation you want. You also may have a check valve that's going bad. The problem is that I'd have to see the setup around the pump and filter to even get an idea of what goes where. My pool has electric activators for the valves that allow automatic operation from inside the house. I adjusted one incorrectly once and it activated the valve backwards, and I had to readjust it.
Q:Heart Valves?
My dad had his replaced because he had rheumatic fever as a child. Many people have them replaced due to congenital defects of the heart. If you are asking why the replacement valve went bad, my dad still has his the original replacement. He did say that the valves made from pig, cow, or cadaver only last 5, 10, 15 years.
Q:What causes valves to leak?
well maybe the sugeons didnt fix it right or they cut and accedental hole... good luck in the future
Q:I can get my trumpet valves unscrewed :OOOO?
Well on the valves you will see there are caps on the bottom and top of the valve. The top cap (it is located at the top of the valve itself, not the button you press - it is the cap that the button lands on when pressed) you unscrew that and take the valve out to oil it. Just make sure you put it in back correctly, if you put it in incorrectly it will not play properly. Also don't drop or dent the valves as they are very delicate and the smallest dent can damage it. Make sure that when you unscrew it that you only use your fingers. DO NOT use any tools to get it unstuck otherwise you can damage the instrument. It would be best for you (because you're new at the trumpet) to take it to the local music store and ask them how to take care of a trumpet. I am sure they will be happy to show you. Hope that helps
Q:Will a tire go flat if you just take out the Valve Stem Cap?
no, the cap for the valve stem is designed to keep dirt out not hold air in ! there is a special tool that removes the valve stem, and some manufacturers have cleverly placed it on the top of the stem cap(so you would remove the cap ,turn it upside down and the metal tool will fit into the valve and unscrew the stem.), otherwise you can get one at the tire dealer or SEARS ,It's about the size of a pencil
Q:Replacing dirtbike valves?
you *can* just put the valves seals in and run it but it is NOT recommended. If you want the best seal which will = the most power, the valve seats need to be cut. If your not running a titanium intake you could get away with just lapping the valves with course and then fine lapping compound. I know a lot of people who just lap them in, but the most professional way with the best results is to cut the seats.
