How much water is necessary to activate it? I'd like it to pump down to 1/4" of standing water or less.

I don't have a manual in front of me, but I think it will go down to 1/2", but it sure seems like mine goes down to about a 1/4" and then will shutoff. On my cover, it often pumps it almost completely dry in one section, shutting off until water migrates in from other sections to "fill" the area around the pump. It then pumps that down as well. Rinse and repeat....it works very nicely and I'm VERY pleased. Much better than my previous pump that now seems more like a toy than a pump.

It will do that. It doesn't take much water to activate the pump. When I was pumping the water off the pool winter cover, it kept turning on whenever it detected more water and it didn't take very much at all. This pump is heads and tails above a Rule. Hope this helps !

If your cover is taut, the pump will sink by its weight and be the lowest point on the cover. It will pump to 1/4 inch of the space it is in, but because it is the lowest point your cover will be dry. Works well for me.

if you see there is a level line on the front of the pump just below the blue thing the blue can be removed and it still has to be about 2- inch. before it comes on

The waterbuster will pump lower than 2 inches in a level area but not less than an inch because the water has to be in the pump area. When the unit quits emitting water then shut it off or you will burn out the pump.

The current draw varies based on the lift or head height you wish to pump the water up to. It is supposed to be a 25 watt pump, drawing 2-2.5 amps. Hope this helps...

I agree it has to be lower than 40 psi. Probably between 20 and 30 PSA it is designed to protect the pump if the water supply dries up.

The pump must be moved at least 3 times the amount of water in an hour, this is able to move about 1300 gallons, then if it works for your project, this also has an adjustable knob to pressure, I really feel very good. stay tuned for your comments, sorry if my English is a bit bad.

There really is no minimum. I've forgotten to fill it and been very disappointed to find I had only a half cup of (very hot) water. It still shuts off fine.

The pump will start working automatically when the level of the water is approx 8" and stop at 4".Other pumps may be better for you. I use mine under my house in a hole that I dug.

The instructions say 15 psi is the minimum. I have a 50 gal water barrel set up for watering with a hole about 6" away from the bottom, the barrel is almost full, and it doesn't seem to work with this amount of pressure. Granted, I couldn't get the timer to work from a hose, either.

The overall height of the pump is 12". It is not necessary to mount the switch to the pipe coming out of the top unless you have a very narrow diameter opening. If that is the case, the water level will reach 12 to 14" before activating pump. If you have a 10" or greater diameter opening, you can mount the float switch, using a long zip tie, to the top of the pump casing (you can see bracket on top of float switch in picture), the pump will activate at approximately 4.5" water level. You can slide the float switch further down, but the pump will run more often. The float will be below the drain tile. I have two of these used in conjunction with a 12v backup. They were purchased on Amazon and I am a satisfied with them. The float switches are mounted to the casing.

Depends on the house size you wish to use. I used 3/8th's ID hose. Pretty sure you could use 1/4 to 1/2 with no problem. Good pump, kinda noisy.

That pump is set up for a 2" pipe. Reducing it to 1 1/2" will not work, especially if used for sewage.

I tried it with 1/4 inch and there is not enough pressure to go more than a few feet. I wanted to do my raised garden. Spent a lot of time piecing it together and the connectors broke as I was setting it up, then it did not work after the first 3-4 feet. I took it apart, plugged the sprinklers into 1/2 inch and was good go to.

Well, it depends on your hose size, but with a half-inch tube, this pump is gonna push your water a good ways up. Several feet, at least. I wish I could get up and actually do it for you, but, alas, I'm not able to at the moment! It's a very powerful little pump! And quiet, too!

I have my above ground pool lowered almost 2' down and it had no problem pumping out the water. I don't think that you will have any problem at 4'.

4 feet in the air is a long distance to pump for a 900. I had one but it didn't pump very well from my sump so I got an 1100. And I'm only pumping about 3 feet.

We have never had 3' to 4' of water. We usually have less than a foot of water when we pump. A foot of water takes about 2 to 2 1/2 hours. I hope that helps.
