If you have to keep priming it do you have to shut it off before adding more water and then restarting it?? How long before it starts pumping water

You should only have to prime the pump once at the beginning of the day. You only re-prime the pump if the pump sits for a period of time without running. If your engine starts up but does not pump any water after a minute or two, then you need to shut it down and prime the pump. Do not run the pump for more than a minute or so without pumping water or you may damage the impellor. I find it best to use a five gallon bucket of water and a funnel to prime the pump.

there is not an automatic shut off. You do have the option of turning it on so that the machine runs for 1 minute and is off for 1 minute, or something like that. I'm not exactly sure of how long the on/off time is, but it's quite sshort. There is a clear raised line inside the water reservoir for the max fill line. Sort of reminds me of the clear raised lines on the clear caps of liquid laundry detergent. I either take it in the bathroom to fill where there is good light, or I only fill it half full. If it is empty, it will not run.

This pump primes itself when switched on ; then only runs if you trigger the sprayer wand. I've had no trouble with mine after spraying pesticides and weed killer.

It has a red wire and black wire - Red goes to the POSITIVE terminal (+) Black goes to the NEGATIVE Terminal TERMINAL (-). Make sure the hoses are clamped properly, and run the pump until water comes out (meaning it is primed) then turn the valve off and the pump will stop. Every time you open the value you get water and the pump starts. That's how mine works (on a battery).Rich

I also run mine with the cool setting off for a few minutes before shutting it off to dry out the machine. I drain it regularly and don't let old water stay in the basin. There was a smell for a couple days when it was new but it went away. I'm very happy with the purchase.

I run mine on the intermittent setting (it runs for 6 hours)... approximately half the water is gone. I always reflll it before starting it again, so not sure exactly. Based on what I've observed, maybe 12 hours? It automatically shuts off after 6, or 3 (if on constant).

This pump is not self priming. Nor is it auto auto turn on/off. If you leave it running dry it'll run and burn out.

Not that I've observed thus far and I use it 1x per day. It starts when you plug it in and stops when you unplug it. The instructions say to not let it run out of water to pump though so you do have to watch it once your water is getting shallow. Hope this helps!

It is kind of tricky to get primed. Hose may look full but just a little air at first will cause pump to loose prime. I usually turn it on and when it sucks air I turn it off and loosen the strainer basket top to let the air out, I usually have to do this about 2-3 times then it takes off. It's kind of hard to hold the whole hose under water to get the air completely out of it. Hope this helps.

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.

It should start pumping right away. It's possible that the tubing on the white casing that holds the pump is not lined up with the hole that water is supposed to spout out of. Also check the lever on the side of the actual pump, this controls the low/high setting. Hopefully that works, otherwise you might have to return it. One other thing to try is to make sure you have a lot of water in there, maybe it doesn't have enough to pump.

It shuts off after the water level is too low. Just add more water to keep using, or dump leftover water if you won't be using for a few days.

No, this pump will keep pumping until it burns up. Or gets the power shut off. You'll have to have some sensor in the tank to shut it off

It stays on until you turn it off....but be careful not to let the water run out.

The Pondmaster pumps are not self priming, they require a "flooded" sump and most of the time are used submersed. You could use it externally IF the pump is in a hole lower than the water level next to the pond and you physically prime the pump the first time.

pump should be fine for a very short time running dry, if you have to move it turn it off and then turn it back on when you get to the barrel with water in it. It will take a few seconds to re prime the pump once you take it out, and put it in the barrel with water in it. No pump should be run without water as it will heat up and burn out the motor

You prime it by pumping several times. Hold a cup underneath. It is generally recommended to put it half way in, pump until primed, then put I the rest of the way and screw it on.
