Q: I was just wondering if any body got there valve replaced,and if they are still having symptoms..Such as sweating,and shortness of breath.I do not know if i should see a cardologist, or the surgeon who replaced the valve.Any answers would be appreciated.Thank you.: Yes I just know a person just had that sugary like 4 weeks ago.Well after sugary he have to stayed in the hospital about 6 days. He going be out of work about 2 threw three months.He really tired and in a lot pain and he slept after heart surgy a lot and he doing well praise god!!!!!!!.If you have a problem of your heart you should to the Doctor you might have a heart attacked. i will pray for you.God bless u.hoped i helped

Q: i was filling the tire on my car and the valve stem completely came out when i finished, quickly deflating the tire. i could push it back in but then the process repeated itself when i tried refilling it again. is there part of the stem i'm not seeing. the stem that i saw was long and straight and threaded. advise, thoughts? thanks.: Are you talking about the whole valve stem? You need a new one, tire has to be dismounted to install it. Are you talking about the insides, the valve core? There is a tool to thread it in, used to be right on the valve caps that came on bicycles, is available in any auto parts store. Why that would pop out I don't know, unless somebody deliberately loosened it. Or perhaps you have ended up with some of the millions of low-quality counterfeit ones that came out of China a couple of years agol

Q: Water has been seeping out of the sprinklers closest to the anti-siphon valve. Water seeps out of the sprinkler even when the anti-siphon valve is manually closed and not connected electronically. I opened up the anti-siphon valve to inspect the diaphragm, but there is no debris nor it was damaged. To be sure, I switched the diaphragm chamber of the two anti-siphon valves (a suspected leaky one and another good working one), but leak persists from the same sprinklers. I think the leak is from the (float?) rubber seal at the bottom of the stem closing the inlet valve. My anti-siphon is a Hardie (or Irritrol) model 311A series.1) Is my troubleshooting and logic correct? What other components could have contributed to the leak described? 2) At what scenario will water be flowing out of the anti-siphon cap?3) How can I determine if my anti-siphon valve has a vacuum breaker? What is a vacuum breaker good for?4)Which brand makes the most reliable anti-siphon valve?: 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: Hi, I have Orbit valve for a section of my yard. The pressure is really low when I turn it on with my remote. When I turn it on manually at the valve, the water pressure is much higher.: Its possible the valve stem is corroded with stuff not letting it actuate properly open. Turn water off and unscrew the valve then actuate it electrically while watching for a full stroke. Make sure flow control is all the way open when inspecting valves stroke. Remember where you had it set when done or readjust. Also check the solenoid for corrosion and clean linkages. I would clean and coat with petroleum jelly. My guess is valve seat is gummed up so lube the stem and work it manually till it slides open and closed easy then test with the solenoid. Good luck!

Q: What is the purpose of the LNG Vs Propane Valve that has to be installed on Gas Stoves/Ovens before use ? How can I set it myself for Propane ? What negligible effects would I experience if I hook a stove up to Propane while the valve is set-up for LNG ?Thank You !: The difference is the size of the orifice. I've never changed it myself but I don't think it could be too difficult, however I've always had a professional do it for me. The reason for this is that propane and natural gas (methane) have very different Btu contents. Propane has a much higher Btu content and the orifice for propane is smaller. There is also a small difference in pressures of the supplied gas as pointed out below, but it is small. If you hook up propane while having the natural gas orfice installed, you may experience problems with incomplete combustion (soot) and the appliance getting hotter than design due to too many Btu's. LNG (Liquid Natural Gas) is a cryogenic form of methane. It is generally stored at -250 deg F. It is not used for domestic fuel.

Q: I have rented a house and the irrigation timer only has wires of one zone.It goes to a single valve then out to a big round cover with 6 zone pipes coming out of it. What the heck kind of set up is this?does it do a mechanical rotation inside that cover? the zones only come on one at a time but every time I turn it on I get a different zone as they are all Zone 1 on the timer.: The okorder / Please provide pictures if you can, and i can expand more on helping you figure this out.

Q: she 13 and shes always sleeping what is a leaky valve there not telling me enough for me to understand and im a nurse tech im scared for her: I've had this very same problem 4 yrs. ago, which was actually found 20 yrs ago. If the back flow of blood in the mitral valve is excessive and the heart starts to enlarge, then the only thing that can be done is a valve replacement, which i did and live a very normal life now. Watch for fatigue, dizziness and shortness of breath. If these things occur frequently, make an appointment with her cardiologist immediately.

Q: And' the valve leaks......Can the valve be unscrewed from the tank for replacement? Or can the valve be serviced with a new gasket perhaps?: If it is a regular brass valve, you will have to drain the tank first, then replace the washer in the valve with one rated to be used for hot water. You replace the washer just as in any valve by removing the bonnet and stem. there you will see the washer. You may want to clean the area of any calcium carbonate that may had developed on the seat before putting it back together. If you decide to replace the valve, it is a 3/4 inch male NPT hose bib valve rated for hot water service. Personally, I've always thought that if I ever had to change one of those valves, that I would replace ti with a good ball valve that had a threaded hose end screwed into the discharge end for better drain flow. The whimpy valves that they put on water heaters is pathetic! If you use your favorite search engine and just search for water heater drain valve, you will find all kinds of cool replacement valves!

Q: The pig heart is better than our heart but the valves can be used to help us.: cape.uwaterloo.ca/che100projects/... They also use cow - bovine - for valve replacements.
