I realize this pump is meant to be submerged in a sump pit. How much rise in the water does it take to activate the pump?

You can also remove the float and activate the on switch manually whenever you want.

The center of the float that activates the on switch sits 5" above a dry floor. The center of the float reaches 8" at the point where it activates the on switch. So a 3" +/- rise in water will turn the pump on.

The pump is activated when the float rises due to water rising about 6-8 inches above the pump base

I pump water up eight feet. They call that the lift height. I can empty a 650 gallon tank in about 20 min pumping it 8 feet straight up. I should also say I have been using it every day for about 7 months with no problem.

Sometimes mine can take up to a few minutes but rarely longer. Is the pump mechanism installed correctly? Is the water level high enough? (Sorry to ask dumb troubleshooting Qs)

I have no idea. I installed the pump this summer - am very happy but the flow of water in to the sump has been minimal. This spring should be a good test Sorry very happy with the pump though.

In my use of the pump, I have had the pump within a few feet vertical from the surface of the water. Priming and pumping under these conditions has been successful. Trying to prime and run the pump with 5 to 8 feet above the water surface may work ok, but you will simply need to try it. It would be better to set the pump on something in the basement (unless the water is too deep to do this) and then run the outlet hose out the window. Good luck. In general, I have found both the 3 and 4 inch pumps to be reliable and fairly easy to prime.Wally Gwynn

If you mean "Can this pump lift water 50 ft?" then the answer is No. The theoretical maximum is 33 ft, and that would require a vacuum pump. The pump inlet needs to be no more than 3 ft above the water level or the pump will suck nothing. If the pump inlet is close to the water, this pump will pump the water up 120 ft.

I installed this pump about 13 feet above the water (10 feet above + 3 feet depth) with 4 right angle bends and 40' to the discharge. Since I had such a long run, I increased the discharge pipe to 1 1/2". Works great! Faster than my primary sump!

Hi Rolf...not too sure of your question, but when i had it we used it for our septic tank (in the caribbean)...it was okay...the sceptic was about 5-6 feet deep. Honestly it was a bit sometimish (as in sometimes that ball thing wouldn't activate the pump). we got a new one recently for another part of home....We live near a lagoon and its filled land so when the tide is high sometimes the water backs up...the one we got is the Red Lion Rl-SC50V 1/2 HP Cast Iron Sump Pump with Vertical Switch. its available on amazon...highly recommended. it has a much better activator switch (im sorry im not into the correct technical jargon)...hope this helps...but the pump you're asking about was still pretty good Hi Rolf...not too sure of your question, but when i had it we used it for our septic tank (in the caribbean)...it was okay...the sceptic was about 5-6 feet deep.

Not sure if this is what you want to know, but the pump pulls water in from the *bottom* of the unit, not the top. the pump turns on when the water level pushes the float up - after maybe about 4" of water fills the sump crock...

The fitting has nothing to do with the problem. The problem is internal. I believe it is the diagram which will not let the pump shut off once it is activated. Once the water is drained and the float lowers/returns to the normal "off" position, the water never turns off.

We have three of these pumps. One pumps from one pond to another pump at about 15 feet vertical. It has a check valve on the intake so once you have it primed it stays primed. The second pump is at the river, has a 25 foot intake and pumps about 20 feet vertical. It takes about ten minutes to prime because of the lift, but once it is primed it stays primed unless there is a leak in either the intake or discharge. It is really important for priming not to have a leak on the intake. It won't prime at all. One method to help priming is to loosen the prime cap a few turns (not too much), start the pump and allow the bubbles to come up through the cap until all the air has left the pump chamber. Then tighten the cap. The third pump worked for about three days, then died; some kind of defect in the piston or chamber as it leaks oil. Too expensive to ship from Hawaii to the mainland for replacement, so we just bought another pump. Note we are using two inch hoses using a four inch to two inch reducer on both working pumps. Hope this helps.

I believe that the way this one works is by sensing the presence of the minute electrical current or the lack thereof. The sensor must be set so that the pump runs at least 10 seconds. I am assuming that is enough time for the pump to discharge enough water and lower the level of the water in the pump sufficiently to allow the sensor to /not/ sense a current and therefore stop activating.

I use it as a submerged pump. Very little noise because it's under the water. Good luck.

The pump is super efficient down to a 1 foot depth, then gets less efficient until it quits at a depth of 2 to 3 inches. When it is close to finishing, put the pump in the lowest spot you can find.

Hello,The way this pump works is when the water level reaches 2 inches, the float switch is activated and the pump starts to pump. Once the water level empties below 2 inches the pump shuts off. No water will be pumping once it turns off. Please let us know if you have any further questions. Have a great day!Thanks,Paramount Direct

Sorry to say but yes a hole or sump pit is necessary. The motor needs to be under water if it runs very long in order to have the motor cooled. Also the pump will only pump the water level down to about 3 or 4 inches before it sucks air or the float switch turns off. I dont know of any pumps that will do what you want it to do without a sump hole. I have a 50 gallon plastic drum buried in the floor of my basement to act as a sump. You should only need like maybe a 5 gallon bucket buried in your floor if the water just seeps in gradually. If the incoming water comes in in gushes or like a river you might want something bigger.

it has to be below the water or inline with the water source...it's not a self priming pumps!
