Q: i would like to hear from anyone who has actually had the work done. i also would like to know if the valve worked.: A backwater valve is basically a check valve that lets water flow in one direction only, away fom your system, and prohibits any other accumulation from entering into your system, like flood water etc. Yes they work very well unless they get full of junk and stuck open. You can install it yourself on the sewage line, they are about 50 bucks, its simple

Q: I have a Jupiter double horn. The thumb valve will randomly stick down and not want to come back up. It however only does this when I play a scale or am in the middle of a song, so when I ask the director or an instrument repair person to help, they think I'm crazy and see nothing wrong with it. Also, the first valve is slightly bent sideways towards the second valve. I got it used and it came like this. It is not horrible, but that makes it significantly slower than the other valves and sticks a LOT. All repair shops do is take my money and claim they've fixed it when they have done nothing. It is so frustrating. What should I do? And the oil doesn't help with either of these things, which is even MORE frustrating.: Open up the #4 valve cap and flood the top with valve oil, put the cap back on and turn the instrument over. Put valve oil in the crack where the valve comes out of the bottom of the valve case. This can be hard to see. Put some drops on every moving part of the valve action. I can remember the layout of that valve but I don't think you can shoot oil into the valve. Try all that I said above and see if that helps. Rotate and wiggle the valve between each step.

Q: Serious answers only please. I have a 1995 Ford F-250 XL 5.8L 351 c.i. engine. My check engine light comes on periodically when I drive. When I bought the truck a year ago the gas mileage wasn't too bad, about 9-10 mpg. I've only put about 3,000 miles on it this past year, and now the needle drops just driving it across town. I work at a Chevy dealership, and I've worked at another Chevy dealer as well as a Ford. I've always done my own work on my cars and am currently restoring a 1967 Mustang, so I have decent knowledge under the hood. I scanned the truck and it has a stored code for EGR valve voltage too high (stuck open). How bad could this be hurting my gas mileage? It's $160 for the valve and sensor even after my discount, and being a college student that's a lotta $ to pay. I'm selling the truck and need it running perfect when I do. Please, serious answers only, and help is greatly appreciated!: Get out your jumper leads and backprobe the egr solinoid. ok. 1st thing......attempt to kill the motor at idle using the egr solinoid. apply ground to the proper wire(not red) and see if the egr valve operates, killing the motor idle. if it does operate, but doesn't kill the motor......you have some cleaning to do. if it operates, and kills the motor.......the valve and solinoid are ok. (the solinoid should also vent the egr valve vacuum when de-energized) Now.....for the tricky part. AFTERMARKET EVP SENSORS SELDOM READ CORRECTLY. 1. Turn the key on and check the voltages at the Exhaust Gas Recirculation (EGR) Valve Position (EVP) Sensor. The Brown/White (BN/W) should be 5v, the Grey/Red (GY/R) is ground and must read 0.1v or less at all times. The Brown/Green (BN/GN) is the signal and MUST read 0.40v to 0.45v. If it does not, the vertical position of the sensor must be changed BY ANY MEANS NESSESARY. a NEW valve will sit higher than an old one......but sometimes not. There are things you can try to lengthen the shaft to increase the voltage reading, such as heat shrink tubing. This EVP issue is an annoying one (even for experienced mechanics), but has little effect on gas milage, unless it is TRULY stuck open. If it were stuck open.....the truck would be running very rough at idle or die.

Q: how to adjust the valves on a 20 horse power briggs and stratton engine on a sears craftman rideing mower model number 917.276824: if you would like to see a video go to utube an type in ifixit4u lawn mower repair valve adjustment.

Q: We are using safety valves of gas and steam for detergent slurries. Why they do not function?: I suggest that you rethink that application. Even if the valve does function it might not pass enough slurry quickly enough to relieve the pressure overload.

Q: I got new sprinkler valves put in (Rainbird anti-siphon kind). Every time a valve shuts off, it makes a loud squeak, kind of like plastic rubbing (NOT a bang like water hammering). Is this normal and will it go away? If not, what could be the problem? This is annoying because the sound can be heard in the house as it echoes through the pipes.: Rainbird Anti Siphon Valve

Q: When i disconnected my Diverter Valve and made it non-recirculating i drove down the street and my engine cut out on me. it will go a few feet and after the excess pressure is released (PSHH) the car cuts out. i reconnected the valve tubing making it rec-circulating and it works fine. im baffled i know VW is supposed to run a DV but last night i saw a stock VW GOLF running blow off and he was stock. any ideas? it is an after market DV made by forge.: Yea... The 1.8T is made so you have to recirc your dv. You can run a BLOW OFF valve off of your throttle hose, but thats a lot of redirecting and work for some silly extra noise. Chip that Passat to get some more turbyturbo noise. Y was there a stock golf with a dv? I'm confused...

Q: Hi, I am a junior in high school and I play the trumpet. For the past week or so my 1st valve has been odd. It gets stuck badly when it hits all the way to the bottom, and I can't seem to get it to stop. Normally when valves are sticky I just use some valve oil and it helps a lot. But it doesn't seem to work this time. It is a Bach if that helps. I think there are other types of valves so I'll say that there is a spring inside from like the middle to top. If you could help me out that would be great! Thanks =): Instead of valve oil, try kerosine. This is no joke. I found that kerosine cleans the **** out of the valves, and makes for smoother valve action. Put about a 1/2 pint in to a a peanut butter jar, and you can let the valves soak a for a few seconds before you put them back in. i got this tip from a trumpet player who played professionally in a dance band.

Q: How are they different from other valves ?: Test valves are typically needle valves but I have seen some occasional usage of 1/4 to 1/2 inch globe valves and ball valves used as test valves for sampling. Pressure gauge installations may have test valves installed just below them. The valves are used to isolate the gauge from the system pressure, a second valve is used to vent the trapped pressure so the gauge could return to zero. The same vent valve could then be used to attach a calibrated pressure source to the pressure gauge so as to check (qualify) the gauge reading against the standard. This was done on select gauges where a quick in place qualification could be done without the need to physically remove the gauge from the gauge board. I have also seen test valve setups in systems using a three way valve in a setup to scavenge the sensing line with a clean fluid. This is done when dealing with a slurry which could block the sensing line suach as in a quick lime system. Clean water would flush the line before and after a reading so as to not trap material in the sensing line which could build up and block or cause a false reading. Test valve location also gives a handy mean to obtain a sample of the process fluid.
