Q:Leaky Toilet shutoff valve....?
This is quite common. If water is leaking on the floor from the hose, replace the hose with one of those user friendly flexible hoses called toilet supply hoses from Home Depot or your local hardware store. It could be the gasket but your hose is probably old and replacing it may save you a small flood. Your shutoff sounds like it needs to be rebuilt, but you as you mentioned, this is not critical because it is on all the time anyway. You can try buying the exact same shutoff, then shut off the main water supply, then take the shutoff apart (without removing it from the supply pipe) and replace the guts of the valve. The part where it attaches to the incoming supply is probably fine, so rebuilding the guts of the valve should work. Use Teflon tape when you connect the new supply hose and be sure to drain the water from the back of the tank with a cup and sponge before you remove the old supply hose.
Q:mitral valve prolapse...?
sounds more like anxiety to me.I agree wid Rhianna
Q:automatic sprinkler valve problem?
No. that's not gas tight and the plastic factors would possibly no longer delight in the petroleum ecosystem. you will choose a valve it is meant for propane. And the suitable valve would matter on the rigidity the place you meant to place in the valve interior the line. you will additionally would desire to layout the entire element very intently - no open touch relays - to steer away from a spark that would spark off errant propane.
Q:What would happen if a PCV valve disconnects while driving?
If the PCV valve becomes disconnected it allows a direct intake manifold vacume leak. This will cause the engine to stumble and run bad and even die during idle. It is easy to lacate and fix. Look for a medium sized hose running from your throttle body on top of the intake going down to the top of one side of the valve cover/s. You should see the PCV valve. Just ensure that it is connected. To tell if one is working properly you need to clean it up and blow through it. It will allow you to blow one way and not the other.
Q:Need help replacing the old valve stem for tub/shower to replace with new valve stem?
Check back on your website to see if they have the procedure for removing/installing the new stem. These usually have to be turned to allow them to be removed. You should be able to purchase a tool to help you release it. Also, be aware the old stem could be hard to remove due to build-up and/or torn seals. After you get it our, try to remve and deposits in the valve and then apply a little lubricant to the new stem before you insert it. Be sure the lubricant is compatable with the seals.
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.
Q:check engine light- valve cover gasket?
the oil may need to be changed check your water and transmission fluid check the brake fluid, have someone to put a new gasket in that is where you may be loosing oil
Q:i have a 96 mitsubishi galant and when you press the accelerator it rattles in the valve cover?
You might not need new valves or valve guides. Mitsubishis, along with many other vehicles, use hydraulic lifters which give off a ticking sound. They're located between the rocker arm, or in the rocker arm, and the head of the valve. It's very common and will not harm the engine. However, if the sound you're hearing is more of a rattling, like putting some nuts and bolts in a glass jar, you may need to pull the valve cover off and inspect for yourself to make sure that the rocker arms do not have any play to them while they are pushing on the valves. If there is any play in the rocker side to side, you may need to replace those rockers. However, if there is any play up and down you may just need to replace the lifter. To better check if you need new valves or valve guides run through this checklist: Are you burning oil? Have you done a compression test (both wet and dry)? And if so, were the compression numbers within spec? Have you felt a loss in power/idle quality/gas mileage? Is your oil level correct/using the correct oil/non-FRAM oil filter? At your next oil change, instead of using the recommended 5W-30 engine oil, try switching to something a little heavier, such as 10W-30, to cancel out the effect of possible lifter tick. Do not use a FRAM oil filter if you have in the past since they're filters tend to have additives that are unnecessary and may cause the engine harm.
Q:How does a solenoid valve work?
A double solenoid has two solenoids, and when voltage is supplied to one (and not the other) the valve shifts. Note that if voltage is supplied to both solenoids at the same time, the valve will stay in the position is was in (i.e. it won't shift since the solenoids will be working against each other). This is typically not desired, so make sure you remove voltage from one side when supplying it to the other. If no voltage is supplied to either solenoid, the result will be the same as if voltage is supplied to both, in that the valve will stay in the position is was in. What this means is that the cylinder has no home position, so when power is cut, the valve will stay where it was at that time, and the cylinder will continue to do work in the direction is was working in. Again, depending upon what the cylinder was doing, this may or may not be desired. For Conrolling with PLC you may need to wire two discrete outputs of PLC to those two solenoids using relay. And the ON/OFF those two outputs as required.
