Is there a flow switch available so the unit only works when water is needed? If so how much is it?

The flow switch requires a different transformer/ballast: iSpring 1-GPM 11-Watts 110-Volt Transformer Ballast with Smart Flow Sensor Switch for 11w UV Disinfection Sterilizer System -- 35.99 on Amazon

There is not an on/oft switch. I would suggest to get the aquatop brand instead of the sun sun.

Sure - why not? Hook to hose - set timer - turn on water -Remember, it shuts off on time, not amount of water.

Don't know - the unit i purchased did not have that switch - but works great!

I honestly don't notice a water flow reduction - and if there is one it is not close to 1/3. I have owned this brand/model for many, many years (I am currently using 5 of them) and when one goes bad I definitely notice the reduced flow rate. For me, the convenience of having these timers far outweighs the infrequent problems that I have with them.

I have this switch installed in two of my boats. I am not sure exactly how much water it takes to turn off and on. But I do know that the water level to turn it on is higher than the water level to turn it off. Every time I check my bilge's they are very dry. The pump and swithc must be mounted on the lowest part of the bilge as close to the stern as possible. And if you are not happy with it you can always return it to Amazon, their return process is the best.

Yes, if the flow switch is not working your chlorinator will not work either. The flow switch sends a signal to your salt cell and tells it to turn on. The reason for this is so your chlorinator doesn't accidentally run and create chlorine while your pump is turned off. Replacing the flow switch is a really easy and fast fix, just make sure the arrows on the flow switch are pointed in the same direction as the flow of water. Easy peasy!

Yes, but maybe not at the same time. Flow rate goes down to maintain set temperature. Be very careful about hard water. It will clog the unit. Mine clogged after 6 months. I think it NEEDS soft water.

you need a float switch for auto operation, they are sold separately.this pump will run continuously when connected, water or no water.

No. The on off switch is on the part that is lowered into the water. best way to stop flow is just to lift it out of the water- it doe not appear to be damaged if it runs w/out water in it for a little bit. My guess is that was no on/off switch at the top to increase reliability and reduce the cost of the device.

You could adjust your hose flow for the volume, there is no timer function. It's a pretty simple set up. It measures the water flow. Be sure to buy spare batteries as soon as you get it. I'm only using about one and a half a season, but they go out with zip for warning.

I have mine on a switch, it is not an automatic on/off water activated pump.

No there is no manual on off switch,the unit has a cord and plug. I ran it o a switched outlet. Its a centrifugal pump so if water drops below the foot valve the pump will continue to spins which doesn't damage a centrifugal for short bursts. I suggest a pressure switch be added so if pressure drop the unit will shut of if that is a potential problem. Mine is on a very low pressure system so I dont need a foot valve. Mine is used as a booster for pressure if the main pumps fail to keep up flow.

There are various models. Mine has a flow switch that only turns the lamp on when there is sufficient flow through the filter.

Yes however you must have good water pressure going in to do so once you get the selected temp, there is a water saver device in the unit that will control the flow but should work fine

No-only comes on when you need your water pressure drops below a certain level.
