Should the valve be in the up or the down position when you are using the pump.

I don't see any diff in the valve position when using the pump. What I notice is the entire top goes down. Too much pumping causing you not to be able to close the side tabs. Remember I don't close the side tabs until I've pumped out the air. That way I know when the air has been removed. I love these things. There the only ones that I've purchased that work. I don't put them in the dishwasher and if I have any problems holding air I put a little olive oil on the valve and rubber lining. Gary

In the up postion. The pump is what takes the air out and then the button goes down a little.

if you lose air, it won't be significant. Most valves are in-line, not 90 degrees.The shock, or wheel really should be designed for in-line attachments - not the pump's fault.

Ii came in the vertical (up) discharge configuration and this is the way I used it. I think it is possible to rotate the pump 90o.

Put it on the valve while the lever is in the down position. Pulling it up is what locks in place. Took me a minute to figure that out as it's opposite to every other pump out there.

No. the water level needs to be above the level of the top of the pump (as Pictured) for the float valve to trun on. I suggest a Sump.

I usually have to pump it up before i use it. It seems to loose air after use.

I agree with JEB. if your concern is the strength of the flow, there is a valve to regulate it.

it is hard to say with out seeing what you are useing it for . on a sump pump you tie wrap it to the pipe or pump so it will hang down as the water rises the float will turn up and the pump will start and lower the water level

You can install a check valve in any position you wish, however I am not sure why you would ever need to use it in a horizontal position. One uses this valve to stop back flow.

I have a 2500 pump and my goes higher than that, it goes about 10-15 feet up and yes the valve should be shut for the waterfall action, less waterfall open valve as needed.

I don't know but you can turn the valve off at the top to lessen how much you lose..

I have mine right after my pump, I used mine to take some of the vibration out of my line.not so sure if I like it.

It only works on the low side. The high side has a different type of valve.

I don't know where these people are getting their information, they are all wrong. The valve is a ball valve and can bet set anywhere in between. It doesn't have 'choices'. As the pressure of one side goes up, it goes down on the other side until one side has all the pressure and the other side has none.

I didn't buy the check valve for a pump such as you appear to be using. What is the purpose of the pump and why are you concerned about back-flow or back-flush?

Make sure your valves are in the right position of they are anyway lose you will lose air. Valves are very touchy but the will hold air if they are in the right position. I had no problem with mine after figuring out the valve adjustment.
