The valve is closed with the 110V power shut off. It opens when 110 V power is applied.

No, that is not the correct operation of the valve. The valve is normally closed when there is no power input to the valve and it opens when power is supplied to the valve.

No, this is normally closed and then open when power is applied. I'm very happy with the two of them that I bought.

Valve in your case should be normally open. When the valve has power the valve is closed. You want a N/O valve. The normal state of the valve is when there is no power. Flip your argument.

I have installed 3 sumps consisting of a 'sump pump' and a battery operated backup pump such as the one were talking about. If the electricity goes off then you need the battery backup system. To buy just a 'sump pump', you can google sump-pumps to find what you need. A very good place to start is with a company called: PumpBiz. http://www.pumpbiz.com. I hope this helps.

I have seen a solenoid valve powered to the same power and the light. So if the power goes out, and the UV light shuts down, there will be no water. That way you aren't getting untreated water. Just a thought.

This would not be a problem for the pump, but you would need a controller panel for it where you could schedule any change in speed and simultaneously control any valves that might need to be opened or closed. I would call their technical customer service. My phone call to them after a long wait was more helpful than I anticipated.

It really depends on the purpose you want the pump for. Sump pumps are often coupled with the float switch, so that whenever the water level rises to a certain level the pump turns on to purge the sump. If you want to control when the pump runs, emptying ponds, pools, etc, then you wouldn't need the float switch.

I presume you are talking about the valves on the pipes coming out of the wall. If the hoses point up and the handles are on the bottom of the pipe, then, looking down at the fixture, you crank counterclockwise to shut the valve. It is an opposite action from your viewpoint. If you are still uncertain, then crank the valve handle to the limit of its travel in either direction. Then turn it the other way. If you suddenly hear water rushing through the pipe, then obviously it had been shut off and now the valve is open again.

Yes, i had the same issue. don not open the shut off valve to full. Adjust it by opening it from quarter to half, again depend on your water pressure. I was fine by opening it a little less then quarter.

The pump has a thermostat in it and when it senses a 6 to 10 degree rise in water temp it shuts itself off, so it never runs continuously. Now I am referring to use with an on demand water heater. It should work the same pulling warmer water from a tank type water heater, senses warmer water in the line and shuts itself off. Hope this helps. Bill

No. You control flow by limiting the outflow. I have a valve on the output and the pump can run even when it's completely closed.

You control the pressure on the system by the size of the outlet of the barrel into the connection and by controlling the volume of the water contained at one time in the barrel. You will have to do the math to figure the necessary volume = water pressure. You can do this without the timers if you wanted to manipulate manually. Great idea. Will you use solar energy for the battery?

Interesting question. I think you are asking whether the timer opens a pilot valve and then line pressure opens the main valve, or whether the timer opens the main valve. It is my impression that the timer opens the main valve and thus it would work with low pressure - but I may be wrong. I have actuated it when it was not connected to water and I heard it click. But that could have been a pilot. I stopped using mine since it stuck open one night, neighbor called me, and I had to drive to my cabin in the forest to turn it off. Easy way to find out - buy and send it back if you don't like.

Hey David- I'll tell you what I think the intention was for having actually 2 valves (yep, if the one at the base is closed, the one near the outlet has no effect)- the one at the base is kind of a safety- when not in use, it's just an extra protection in case the end one is accidentally hit or if somehow the swing sections start leaking (BTW, I've had mine for a couple of years now & no leaks) and also protects in case the outlet handle is accidentally opened when maneuvering the outlet into position but not being as careful as necessary to make sure the valve stays closed until you get there (I've had my hand positioned improperly in the valve area and started the flow before I intended to a couple of times early on)...so, simply said, in my opinion, it's just a safety.

this item is used on water or liquid tanks that you don't bad stuff siphoned into them when you shut off the supply, when valve is turned on and lets fluid flow ,when valve is turned off the pressure releases and breaks vacumm. the female fits a regular faucet and a hose screws to the other end.

No, it is either on and pumping or off when power is disconnected. Unless you have a way to turn the power on and off from water level then it is on all the time.

The through valve is manual, So you have to open it and you have to close it. However when you close it, than it is closed, nothing comes out. So you need not to buy any cap. This unit is great for low pressure watering. I was disappointed when I hooked this up to my lawn sprinkler and the pressure dropped significantly as this unit is a little bit of a throttle, or bottle neck. But it would be perfect and simple for low pressure garden watering. The timer is super simple and easy.

If power is lost to the main pump or anything prevents the main pump from operating, the backup pump takes over. The secondary pump has it's own float to activate it. This float is set higher than the main pump. So, if the main pump stops, the water will rise a few inches past the point where the main pump would kick on. This activates backup pump.

Your float turns a switch on and off on or near the motor. If you can lock the switch in the on position (many options), and your pump runs full time, you can use this switch by plugging it into the outlet first and then plugging the sump line into the control. Directions aren't the best but mine still works. Good for up to 14 amps. I'm always cautious with low stock items. They could be returns but Amazon backs up their products.
