Q:how to replace relief valve on hot water tank?
Turn red dial to pilot.Shut the cold water feed off. There is a drain located at the very bottom of the tank youll need to hook a hose or hold a bucket and drain some water out of that. It doesnt need to be much a few buckets or a couple mins of hose will be fine. Then simply un-screw the old one. Put teflon tape and pipe dope if you have it around the new one and tighten in securely. open hot water at your sinks and turn cold water to tank back on slowly and let the sinks run until all air bleeds out and then shut them off. Re- light pilot. Done.
Q:Anti-Siphon Valve leaks = Where??
I work in a printing plant,and our city mandates anti-siphon valves on all our commercial equipment,so I have a little knowledge about these.We used to call these pesky creatures Vacumn Breakers,but now they are called anti-siphon valves,but what's in a name-they both are supposed to accomplish the same thing.Should your water pressure drop,due to a broken main or largefire,these devices are supposed to prevent contaminated water,like the contents of the Agfa Encomatic plate processor rinse tank,or your irrigation pipes,from being pulled back into your plumbing ,and then out your faucets when pressure is restored ,which could make everybody sicker than pooches. The way these work on industrial models is a little more complicated,but the principle is the same,for water to flow through the system,a certain pressure must be maintained.Our older models had a spring and diaphram arragement,the water pressure pushed the diaphram against a seal seat,with a spring behind it.As long as the pressure in the valve was greater than the spring,water would flow through the vave,but when the pressure ceased,the spring closed the diaphram,which in turn opened a vent that allowed the water to drain hence,vacumn breaker.These had to be at a point above the turn-offs,by the way,and when they malfunctioned,due to debris or rusted springs,they could either fail,and stay open,or fail,and water wouldcome gushing out the cap. The conditions you desribe sounds like a low pressure situation,where there is not enough pressure to flow through the anti-siphon.Is your supply line kinked or crushed?
Q:trumpet valve keys !?
Unscrew the the valve cap on the appropriate under the button. attempt to softly pull the valve out. you may would desire to artwork it back and forth till it loosens up you may upload some oil around the the sting of the valve cylinder. as quickly as you have all 3 valves out sparkling each of the particles off of the valve, you ought to use an sos pad to get dissimilar the heaver stuff off. Wipe each factor off with slightly of lighter fluid and a sparkling rag. sparkling the valve bores including your snake. Stuff a rag down each hollow to get the stuff the snake loosened up. Reoil the valves and the cylinders and reassemble.
Q:Tricuspid valve leak normal values?
finding on the severity of the valve situation it fairly is severe. If it have been severe you certainly could have indications that could assist you recognize previous to now. Ask the physician how severe the valve insufficiency is. A mitral valve prolapse could make you sense mild headed. The tricuspid valve insufficiency could convey approximately severe issues. There are various circumstances that would reason this. it fairly is great to your heart professional to describe your situation. In any experience it fairly is no longer something to fool around with or placed off. while you're actually not chuffed with the solutions do no longer hesitate to get a 2d opinion.
Q:roman tub valve ?
Remove the valve and take it to a plumbing supply store. Home Depot and the like may have what you're looking for; but you're more likely to find it at a plumber's supply. They are the only ones I've ever found who carry odd bits.
Q:Bovine or Mechanical Valve for my Mitral Valve Replacement Surgery? Experienced people, please help!!?
I had open heart surgery, repairs to my mitrial and tricuspid valves. On the mitrial valve, an Edwards Lifescience ring was placed to tighten valve and the tricuspid was just tightened. That was five yrs ago. Have more energy and feeling better, still. My surgeon did mention placing a porcine valve but once they got inside my heart, the DRs. choose the lifescience ring. I do take an anticoagulant but for other reasons for over 8 yrs now.
Q:Reed valves?
reed valves are in a 2 stroke cylinder head they are exactly like they sound like in a clarinet.. when the piston rises they are closed due to the position the port is in the cylinder . when the piston is down stroking it creates a vacuum hence the reed valve opens and the piston starts to rise closes the reed valve.. 4 cycle engines have mechanicaly activated valves from a timing chain and a camshaft which controls when the valve opens so the answer is NO NO NO
Q:Water main valve broke off?
If your on city water, you should have 2 valves, one on each side of the meter. The city is responsible for the valve on the street side of the meter. You are responsible for the valve on the house side of the meter. Follow the supply back to the foundation. Sometimes the city valve is not always next to the meter. If only one valve, my advice is to call a plumber. An alternative would be to spray the top of the stem with WD 40 or some other lubricant. Using vice grip pliers, gently work the stem back and forth until the valve opens(or in your case closes). Clockwise closes, counter clockwise opens. I caution again....... If the handle snapped off, the valve should be replaced as it is very old. You could end up snapping the valve off completely if not careful. If your successful getting the water turned off, cut the pipe on the house side of the valve and install a new shutoff (compression type fittings recommended). Once installed, leave your old valve open and use your new valve to turn the water on and off. Good luck.
Q:Toilet wall valve is not working properly?
Check your fill valve (inside the tank) first. If it appears to be working properly, turn the water off outside the house, drain the tank, take the filler tube ( from the valve to the bottom of the tank on the outside) loose at the valve. Remove the valve and inspect for obstructions, such as calcium and or lime deposits. You may need to replace the valve as they will occasionally wash out over time. Reverse this process to put everything back together, and be sure to wrap the male threads on the supply line (pipe sticking out of the wall) with teflon tape.
Q:if i took off the little rubber hose connected to my egr valve,and the egr has no suction?
You didn't tell us year, make, model, and engine so we're shooting in the dark a bit. First off, EGR valves are NEVER on at idle. That would kill the engine. The vacuum only comes on when certain conditions are met. First, the engine has to be at full operating temp. Then, the throttle has to be open a certain amount. If you own a late model vehicle, many of them used duty cycle solenoids that literally pulse the length of time the vacuum solenoid allows vacuum to go to the EGR. That's how the computer regulates how far the valve opens. So, the only way to tell if yours is working without owning a scope is to use a hand vacuum pump and attach it to the vacuum port. Then apply vacuum and release it while watching the valve open and close. If you do this while the engine is running, the opening valve should make the engine run really rough, if not die completely. Next time please give us more make/model info
