Does the unit activate automatically in freshwater?

It depends on the water. 'Fresh' water is generally not pure H2O. Even tap water has dissolved solids in it as evidenced by the calcium or 'lime' deposits seen on faucets and sinks after the water evaporates. The strobe is activated when it senses an electric current between two electrodes. When dry, it remains off because air is a poor conductor. It will probably not activate in pure rain water or distilled water, which are also not good conductors of electricity. I have activated the strobe in tap water, but it takes longer than in sea water. Most fresh water lakes and streams probably will activate the strobe, but the time to activation will vary depending on how pure the water is. The best safety practice is to test the strobe just before use by putting it in the water you encounter to see if it activates.

"Light may not activate in ordinary tap water." That is, your tap water may be very "soft", i.e. close to distilled water, which is non-conductive. Lake water should be sufficiently conductive to activate the light. I am going to use this light with HIT offshore vests on lake water.Suggest lithium batteries.

It did while ago!!! Four inches of rain in an hour and a major creek .25 from my back door! Good investment!

Yes. I do it all the time. It does need to be watered in to activate so I I usually do both just before a rainy day.

Not directly. If you have a pressurized system as soon as there is a demand for water the pump should activate. Otherwise no.

No. It doesn't. If it fails to activate call the H2O company. They are efficient.

I agree with other reviewers- it is manually operated- on and off. By the way- mine did not require filters as it has a little wire basket- just empty and rinse!

We have the pump installed, and it works well. The pump only starts when we push the button connected to the unit, or when we push the button on the remote control. When the water temperature is reached, the unit stays off until the button is pushed again.

I just hooked mine up to the water source a few weeks ago.Functioning worked the same for me.When unit is turned off, hold finger to the screen while turning the unit on. This brings up the menu and you should be able to set the auto on/off times. Note once it's unplugged the clock time is not set and so the auto on/off is not selectable. You must first set the clock time and after that is done the auto on/off button becomes selectable.Hope this helps.

I am almost certain the answer is "no". It turns valves on and off, and has no way of sensing water pressure, etc.

Afraid not. It's a simple circuit connected by water. So it's either on or off. It's fairly sensitive.

Yes - The "See-Me" LED Rescue Strobe does allow you to deactivate the light so it doesn't activate in water. You first turn the light top clockwise fully to the "ON" position and then turn it fully counterclockwise to the OFF/AUTO position. Although the instructions state that the light might not activate in regular tap water, I tested the light in a pot of tap water and it does function as designed (you must slightly agitate the water, I guess to simulate wave action). This is a really good strobe. The instructions are well written and easy to understand. It only takes about three minutes to read them, test the strobe, and fully understand its operation. I carry it as an emergency beacon in an Eberlestock Operator Pack I have set up as a mission-oriented emergency pack. I purchased the strobe more for use as a location beacon for helicopter extractions rather than for water purposes but it certainly will work in both situations.

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.

No. They will automatically turn on once the water comes out, but you cant turn it off.

Yes, there is a ball float inside that turns the unit off automatically when it reaches the "off" water level.

Unfortunately yes. That is one way to vlear the unit after an alarm. According to the manufacturer when you plug it back in the alarm (which is different from the wetness alarm) indicates that it is active. Hope this helps.

Yes it does. Unit takes some fine tuning once on water. Spend some time with it and it works well.

Yes it does....you can set it in one hour increments. In addition, it shuts off automatically if the water tank runs dry.

It can be switched on manually, but also has the automatic feature (turns on when submerged)
