If the primay pump fails will the back-up pump start to prevent water from overflowing?

Yes, because the float switch for the back-up pump is mounted higher than the primary pump's float switch. If the primary pump fails, the water level will of course continue to rise until it triggers the float switch for the back-up pump to turn on.

That's the idea.. It's a 2nd completely separate pump, with a separate float switch and power supply. If the water level gets above the backup pump float switch, either because the primary can't keep up or has failed for some reason, the backup will turn on. This assumes you've installed and maintained the backup pump in working order. The backup is smaller than the primary, and battery powered so it may not keep up if there is an extreme of flooding.

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.

Yes. It's a great system. I sleep well at night. My newly finished basement is well protected.

If you have water in the top when the bottom is full the system will overflow.

Yes, you are right. It has water sensors. If there is no water to touch the sensors, the pump will not start. Thanks for your interest.

That's what I have and before I got this I burned up 2 outdrive pumps because the single feed does not supply enough water. I have had no trouble since purchasing this unit.

I can't assert ruing.BUt 「backing water to pipe」may increase water pressure on pipe and back flow valve.I suspect this pressure decrease efficiency RO(back flow valve can't work perfectly).If it may look like running normally,you should check water quality with TDS-meter.In my case, this pump system decrease water quality.

It depends. Mine stopped once when my water level was too low. I would keep an eye on the water level

I cannot find the instruction manual.. but I would say probably not because the water was near empty and it didn't shut off. We fill up the container daily....Sorry I couldn't have been more help.

Check these things. 1. Is main breaker on? 2. Is water passing through system? 3. Is there sufficient back pressure. If water is not restricted on discharge side of pump, the lack of back pressure will not allow unit to go on. I used a ball cock valve closed one third to acjieve results. jib73@aol.com. good luck.

Yes when it runs out of the amount of water you put in it automatically shuts off.

I have not had this problem with either pump I installed. Possibly water is not staying in the line and the gaskets are getting dried out or your intake and overboard discharge are clogged and water is not flowing smoothly through the system or (if you have one) your holding tank is full so there is no place for the water to pump into...

I have had this happen a few times now. If the water level is as high as it should be, it will have no problem flowing again when power comes back on. But if the water level is too low... it has a hard time. Its a great filter.

This is a pretty simple device, and I have not experienced anything like this. Assuming that your water supply has a constant pressure, I would suspect that the pump may be failing and is "locking up" intermittently. I would check and see that the hose from the water supply is not kinking and the hose to the nozzle is also not kinking, though either of these would be fairly conspicuous.i would think. The first one of these I bought failed completely after about 8 hours use, I returned it for a replacement and have had no problems with it.

I don't have an answer for you on that one. I didn't try what you did. The pump worked fine, we are using it as a spare.

I am not using the safety switch and did not do anything to the level switch wires. If the pump fails for any reason the unit will overflow but this was not a issue for me.

If the sump area is small and your discharge is at a somewhat high elevation, the water will flow back in and cause the pump to continue to restart. I would suggest you install an inline check valve just after the pump discharge.

It's been done. It'll have to be in a large round container so the float can hang down alongside the pump, then the water can lift it to start the pump. You'll have to put a flapper valve in so the outflow tube so water won't come back out of the pump when it shuts off.

I ran mine separately. I suppose it could impede the flow if the pump (which discharges under pretty low pressure) was trying to push water into a pipe that already had static water sitting in it. The venturi pump has a check valve in it close to it's intake...which keeps the venturi primed...and of course also keeps the water from flowing back into the sump hole.
