- Q: what does mild sclerosis of aortic valve means? Why does it happens and what is its curethanks
- It means you have some plaque build up in ur aorta. causes are bad diet or gentics. change of diet can help
- 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: We are using safety valves of gas and steam for detergent slurries. Why they do not function?
- Not sure but I would check for corrosion inside the valves. I assume the valves are positioned so that they are not exposed directly to the slurry. If possible, empty the system and test with compressed air to see if the release at the correct pressure. It is very important that this type of safety device work correctly. Also suggest contacting the mnfr. You get what you pay for so I recommend that you do NOT skimp on investment in safety equipment, consider the cost if the safety equipment fails to do what it is intended to do. Killing employees is not very popular with surviving employees and it costs a LOT of money.
- Q: If I flush the toilet the drama begins. While the toilet is flushing, if I lift the lift of the lid of the tank cover NOT THE SEAT, water shoots up straight in the air from the top/cap of the fill valve. This is a picture of a toilet fill valve.

- Q: I go deer hunting with my dad and he has an artificial heart valve. It isn't too loud, but I can hear it about ten feet away if it's quiet enough. Is it possible that we haven't shot any deer yet because the deer can hear the valve and know to stay away?
- I am a deer hunter as well, the deer will more than likely sense your worrying over the thoughts you are having with your dads valve, just relax out there!! Become one with nature, de-stress!! Be grateful to hear the sound of your fathers new valve on life, and be happy he is out there with you!!! These times you will hold with you when he is gone. Make the hunting trips a special time for you and dad. I wish mine were still here to enjoy the hunt with me. Just relax the deer will be there when they are ready. Pray for dad to get the Ultimate buck. Life is short.
- Q: I want to switch off the water in the bathroom only due to replacing sink taps, will water still come out of the pipe if i turn the stop valve
- Assuming that the stop valves are good, turning them off will stop the flow of water to the sink taps. To test them, turn on the water faucet at the sink, then turn off both stop valves. The water should stop coming out of the faucet. If it continues to drip, the stop valves are defective and should be replaced when you do the job. If this is the case you'll have to shut off the main water valve or a valve upstream of the stops to replace them. Good Luck
- Q: im just bored so heres my question who do you think is better valve games (hl2 tf2 css) or bungie games (halo) and why. whoever gives me the best reson gets best answer. personally i like valve
- 0.5 existence and 0.5 existence 2 are extra beneficial video games than Halo a million/2/3. whether im not a huge fan of the definitely gameplay in Valves video games. I choose Halo's engine over Valves. whether, Portal is an marvelous interest. That on my own places Valve over Bungie.
- Q: 1994 Chevy K1500 P/U 5.7 liter 350 4X4 5 speed. When the truck is under a hard pull the valves start knocking, the knock sensor adjust the timing and the check engine light comes on. The code for the light is not detecting knock sensor. I have changed the pcv valve (which was suggested) and no change. This has went on for about 5 years. Doesn't matter the grade of fuel I use. Routine maintance and tune ups have been done to this truck. The converter was taken off 7 years ago because it was clogged. The truck runs rich after the timing adjust. The light resets itself when it is turned off. ( the code is saved)
- Excessive carbon build up on the valves may also be causing pre-detonation which the knock sensor will not be able to correct. If it is a high mileage or a rough service motor it may be time to open it up and see if it's time for a valve job, or possibly a rebuild.
- Q: I have a WRX. slightly modified. im getting some upgrades here soon. clutch, brakes, and catback exhaust. i have a blow off valve i bought a while back, but found out it was illegal here in cali. if you know about blow off valves, then respond. is it worth putting on? what are the consciences of having one illegally if noticed by cops? all i know is that it sounds bad ***! :)
- I doubt the cops would notice and if they do find out which is highly unlikely to happen you would just get a fix it ticket. i live in cali and i hear cars with blow off values all the time so my advice is don't trip and put it on your car. it will sound so bad ***!
- Q: i have an 87' monte carlo ss, 64K on 305 w/ cam, headers, roller rockers and springs. ive been seeing blue smoke out of my exhaust ALOT during start up, but it also continues to smoke at idle, i've been told it's a good chance i need my valve seals replaced and was wondering what the general ballpark was assuming there was no other complications in the process of replacing these?
- budget $300-400 probably to fix the stem seals. if you have ANY thoughts of replacing the heads with a performance set now is the time...
