Q: My sprinkler valve I just put in leaks from the top knobs you turn to allow water to pass through to the 3 main pvc pipes. I turn the water on on the main water line, open the little black twisty knobs to allow the water to pass through to the irrigation lines, but water leaks out through all 3 black twisty knobs. What do I need to do?!?!?!: I have been given the equivalent line from our water application while the strain valve broke and blew up our water softener it is the 1st concern on the line from their tension regulator. fortuitously, it has a lifetime insurance yet their plumber urged me that it incredibly was once the duty city on account that of the strain regulator which they admitted to being at fault as quickly as they replaced it.

Q: We need to replace our erg valve, but we cannot locate it.: Egr okorder /

Q: I'm installing an under-sink water filter. For the saddle valve, how do I drill the 1/8 hole through the iron pipe? What is the easy way to do this? Seems like I will be slipping around a bit. Any tips on this step?: Your best bet would be to support the pipe from the opposite side somehow and then use a small center-punch where you want to drill. Good-luck.

Q: The water shutoff valvue has a slow leak where the hose connects. Its right were the hose to the tank connects to the shutoff valve.....I also noticed when I close the shut off valve it doesnt stop the water completely. Does the whole setup need to be replaced, and if so, is it difficult? Or will just replacing the hose correct the leak?I figured the constant running wasnt a huge deal if there was no leak because you leave the water on anyways, so there is always constant water pressure there.: 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: the pressure relief valve on the top of the tank needs replaced: 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: I am doing a big project on Valve and it's games. I am currently doing some research on the company and wanted to see if anyone had any interesting facts or information about Valve that may be useful when doing research, thank you. :): i just watched it again.. haven't seen it since it was released. Since then they've made Team Fortress 2 free to play, and any gamer that plays f2p will tell ya.. f2p/microtransactions are the future. Also they came out with Alien Swarm, and amazing isometric shooter where you had to rely on your teammates much like left for dead.. but even more indepth group dynamic. Then Portal 2 of course.. and DotA 2 is still in beta but looking great also. I really think the 1 thing that makes Valve so loved is the relationship it has with its consumer/gamers. Especially in the modding community. I know alot of people like me who will stand behind Valve in all their future games.. and that's perty damn crazy to say for a company that is trying to sell you things... especially in the Video Game world where so many are out to squeeze every dollar out of their customers and IPs.

Q: One of the zone control valves in my heating system does not appear to be working. The thermostat is calling for heat, but no water is flowing. If the other thermostats call for heat, the valves seem to open as the pipes above the valve get hot from the water flowing through. The one that appears busted gets luke warm at best. All 4 valves in the system are fed from the same pipe, and the failed valve is the third in the series of 4 along the pipe (and #4 flows fine) so it doesn't appear to be something in the feeder pipe.Is there anything I can do to try and fix the existing valve, can I replace the valve myself? Would replacing the valve top of the valve (the green/gold portion) possible fix the issue (maybe a problem with the operation of the piston? Is there anything I ahve to do before removing the valve top aside from removing power to the valve?: You would need to isolate the valve from the line, and depressurize the system, and I would think that turning off the heater and letting the temperature fall would probably be necessary if you don't want a relief to lift in the boiler. If you make a mistake here you have a very good chance of being scalded to death, or permanently scarred. Also, you may need to sweat and braise the new valve with a torch, so you had better be sure you know what you are doing and don't burn your house down.

Q: What exactly are valves and cylinders when talking about car engines? Say a car has 3 cylinders or 8 valves for example.: There are intake valves and exhaust valves. On the intake side, the intake valve opens which lets the fuel/air mixture into the combusion chamber. At some point (measured in degrees of crank rotation) the intake valve closes, the air/fuel mixture is compressed and ignited by the spark plug. Then the spent mixture exits the cylinder when the exhaust valve opens. Valve configuration varies somewhat, but regardless of how many valves there are there will always be at least one intake and one exhaust valve. Some cylinder heads have 2 intake and 2 exhaust valves which is what is described as the 4-valve per cylinder setup. Regarding Car Cylinders, the answerer says Cylinders in a car engine are pretty much like rowers in a boat. But they are not. Rowers always row in synch with each other. Cylinders are made to be out-of-sync for smoother operation. The more cylinders you have, the smoother the engine runs. Compare a 1-cylinder minibike with a 4-cylinder motorcycle (both air-cooled), or a 4-cylinder to an eight... big difference in smoothness.

Q: I have a 03 civic ex with 96k how important is it that I do a valve adjustment. The engine runs smooth.: the factory maintenance manual calls for the valves to be checked and adjusted if necessary every 110,000. unless they're noisy (loud tapping) they probably don't require adjustment. The older Civics were very sensitive to the valve adjustment but the 2003 won't give you any problems if the valves aren't noisy. that being said, if you notice a decrease in performance or fuel economy around that mileage it won't hurt to get them checked and adjusted. hope that helps

Q: how do you adjust the hyd. valves when motor is running?? thanks, jerry swain: that's puzzling to discover 0 clearance even as the lifters are not any more pumped up. it truly is how I actually have continuously lashed small block chevys, even with the actual undeniable actuality that it may get messy. get rid of one million valve hide, start up engine. Tighten the first rocker nut till the push rod stops spinning lower than the rocker. Then decrease backpedal a million/4-a million/2 turn. Repeat for each and each of the others. This works nicely with new valve practice factors to boot to boot used parts. the downside is oil would drip on warm headers.
