Q:Com wires attached to com and all individual valve wires are attached. The valves work manually( turn on by hand), I open the valve to allow the box to take over and the sprinklers run. Is this just residual water in the lines??: I would test the leads inside the control box first... You will have to run the controls manually to troubleshoot the problem. Get a voltage meter to test for the 24 volts at the transformer connections inside the box... If you do not have the 24 volts then the problem will be the transformer. If you have the correct voltage from the transformer then you can test each of the station terminals to common. Test through each station to see if you have 24 volts at each station terminal, but you may have to remove the wires off to test. If you do not have power coming from each station… then the problem will be the rain bird control. The next step would be testing the wires… If you reconnect the wires… test just prior at each valve location to see if you have the 24 volts between the common and each station wire… if you can prove out that there is 24 volts at this location then you’re down to the final testing. Reconnect the valves – one side to the common and the other to each station wire… Getting the power (24v) to the valve should have cleared your problem. Good Luck… Running the valves manually will not affect the operation of the rainbird control... but with my rainbird valves.. you can shut off the valves completely and disable the electrical controls of the valve... make sure that you have not closed the valve off manually preventing the electrical side... a problem with rainbird controls. This does not have anything to do with residual water in the lines... I would test this side first before you get into the electrical side... could save you a lot of time.

Q:Why would oil be leaking from a blow off valve?i own a 05' gti 1.8t, i have had the blow off valve for about a year now, its a HKS SSQV, but i just revently noticed that when it blows off, there is a spray of oil that comes out..... why would it be leaking oil through the blow off valve? i know VW dont really go well with blow off valves, but it hasnt given me any problems until recently....: I'm having a very similar problem, i'm thinking the turbo might be damaged and leaking oil.

Q:had a water heater put in after that i have low hot water pressure it get hot but goes to a low stream.when i try to adjust gate valve it keeps turning: A gate valve is used as a shut-off, not a regulator. It is supposed to be either all on or all off, and the handle only has a total movement of 90 degrees. When the handle is aligned with the pipe, it's on, and when the handle is perpendicular to the pipe it's off. If the handle is turning more than that, it's broke and needs to be fixed or replaced.

Q:Is there a devise to reverse the flow to a cylinder. Not the pump. But a inline flow deverter that would shift the flow from one side of the cylinder to the other at the end of the stroke automatically without a person interjecting.ie it extends fully then the flow reverses retracting it fully. Then the flow reverses, and it extends fully and so on.Preferably, with as little lag as possible during the transition.I want the pump to run constantly(not reversing) and the cylinder to run constantly. Do not worry about the heat generated.Would love something that ran off the main cylinder(like a secondary piston or valve that would opendivert flow at the end of the stroke) through linkage. But, I am open to electronics if need be. Further more want the return to be metered so that the push and pull forces will be the same(metered through a smaller opening to adjust for the rod).Thankyou: even though this patent claims it will save money by eliminating a servo controller, it would seem to me to be an expensive item in and of itself. Other mechanisms would use linkages and lost motion to control a pilot shuttle valve. This would operate like the valve assemble for steam reciprocating pumps.

Q:where is the heater control valve on a 1996 volkswagen passat: There is no Heater Control Valve. Coolant circulates through the heater core continuously. Air flow is directed through the heater core/ac evaporator in the air distribution box under the dash as required by user input. If you have no heat, there are a couple of things that could be wrong. A bad water pump, plugged up heater core, bad blend door/cable, bad Climatronic control head, or a bad actuator/motor. So, what's your question? What is the car doing/not doing that you think it should/should not do?

Q:I have a yamaha cornet and i took the valves out to oil them. i put the valves in, and now only the middle on makes a sound. when i put down no valves, and doesn't make a sound, only when i press down valve two. i think it is the way i put the valves because it has those holes. can some one let me know what is the right way to put the valves in, like explain or show me a video. thanks.: Trumpet Valve Positions

Q:When you regulate flow with a valve in a fluid circuit, obviously the flow changes. But mathematically, it changes in function to what? the minimum cross-sectional area? I mean it has to have something to do with some integral of sth (since a valve can change the cross-sectional area of a portion of the tube with length of almost zero and the flow would still change dramatically). I have no idea how to work this through. Can you tell me what changes when you close a valve, which makes the total flow change?Please answer asprecisely as possible, this is for a college essay! thanks in advance!: A valve reduces the cross-section of the pipe. .

Q:After shutting off the hot and cold water lines to my washer to remove the unit from my laundry room i noticed a small leak coming from the hot water valve as if the valve is not completely closing. The valves themselves should be roughly 10 years old and were extremely tight when attempting to close them, my question is how big of a job is this to replace the water valve? Is it as simple as turning off the main water to the house and replacing the valve or are these typically soldered on? Currently i just ran the hose for the hot water to the drain line to prevent water from leaking onto the floor so is this something that is a fairly non issue once i hook the lines back up to the washer and turn them back on? Or is this something i should get addressed asap?: Not to sound insulting but the hose will have water left in after you turn the valve off , use a bucket and drain the house before you go tearing things apart. You really do not have to change the whole valve if that is the case, there is a rubber washer inside of the valve which may be worn or distorted from over tightening of the valve.Either way you have to drain the system I would tell you to attend one of the plumbing classes at Home depot to learn what to do they hold them all of the time .

Q:i have been told that a bad EGR valve (exhaust gas recirculation valve) could cause a car to buck or hesitate in mid range speed at low rpms, thats what my car is doing. i work at autozone and i used our code reader and there was a code that stated EGR flow malfunction anyone else have this problem ever? please help me! i dont wanna spend the $120 if i dont need to!: If an egr valve opens too soon you will have a hesitation problem. Bad egr's do not cause problems with drive-ability at cruising speed. It sounds like your egr is faulty.
