Q:Pressure balancing valve adjustment in shower?
the new single handle tub and shower valves all come with a scald guard mechanism.(its code so kids cant turn on the hot and burn themselves). take the handle off and mess with it. it will be grey or black with a bunch of grooves on the outside. keep adjusting it till it satisfies you.
Q:toilet flooded, shut off water at inhouse shutoff valve. now why wont it come back on?
did you strip the knob handle?
Q:how do you repack an OS&Y valve?
where is i get the packing gland material
Q:Valve cover painting in 1990 BMW 525i?
portray won't count. in case you get rid of the area to paint it incredibly is valuable to apply new gaskets! careful with the intake air hoses. they are previous an could be brittle. Even a tiny air leak will reason your vehicle to run poorly.
Q:how many valves does a human heart have?
All four valves are not essential. Many patients have Pulmonary regurg after a surgery for Fallot's tetrology. Other three valves are important but valve leaks are better tolerated on the rt side than on the left side. Stenosis of any valve causes obstruction to circulation and so it causes problems.
Q:Valves on a tuba? Need a tubarist?
bearcat's links only work for a B-flat tuba. There are also tubas in F, E-flat and C, although you don't specify which one you need a chart for. The link below might help as it covers all tuba pitches. And a tuba player is a tubist.
Q:Trumpet valves making weird sound?
I don't think anyone knows, because there's multiple Bibles. And people interpret it their own way, and re-print it with different scriptures. As far as I'm concerned, there is no such thing as a REAL bible anymore. And any beliefs we have today about it are all false. According to one bible, you will be sent to hell on both counts. According to a modern version, you will be excused for doing your wife, and in another bible, you'll be stonned for asking this question (Knowledge is a sin) Interesting that we are the only intelligent life on earth, supposedly made in God's image, and yet the bible says to stay away from the tree of knowledge. Sorry, I don't buy into that bullcrap.
Q:Presta valve snapped!?
By the head of the valve, do you mean the lock nut? The part you unscrew to press in to release pressure? If that is what you mean, it has happened to me several times. It is usually from the way the pump is applied or released from the valve. Hand held pumps cause it more than floor pumps. The thin screw that the nut tightens on simply snapped. It can even happen on a presta inner tube. You can just inflate and ride with the nut broken off. Shouldn't be a problem. If it is like any tubular I have used the valve core is replaceable. This is because tubs come with one length valve and for dish wheels you need to install an extension. Ask your bike shop if you don't know or look up the manufacturer's site for the brand tub you have. They usually say if it has a removable valve. If they don't come out and specify if the valve is removable or not, if they sell extensions for their tires it is replaceable. The extensions are supplied with a little tool to remove and tighten the valve. Simple pliers can be used if you are careful not to squeeze the valve too tight.
Q:Flap valve replacement?
pricey Vongirl, Congratulations on the lengthy lasting heart valve. frequently mechanical valves do not very last somewhat that lengthy. Mechanical, bovine, porcine and donor valves all positioned on out. It in basic terms relies upon on the timing. i'd say two decades with an same valve is somewhat magnificent. i wish, once you get your replace it lasts two decades besides!!!
