Pool Chlorinator experts - anyone ?

I would have been looking for the voltage to be around 24 volts but if you aren't getting any voltage that isn't good for the controller.
The other quick test of the cell is to put it into really salty water ie 10,000 ppms plus and if you get a reaction then it is most likely a worn out cell. the trick here is to pour half a bag of salt into the skimmer whilst the pump is running and see if any change occurs at the chlorinator.

I am assuming you have had the salt content of your pool water tested and it is above 5000 ppm.

Gday Ian,

Thanks for the reply , its a Monarch ( Davey ) ESR 160 and I ended up pulling the main unit apart, there is a safety transformer that takes in 240v and 8.5v comes out , this supply goes to the leads which go to the cell. I played around with the connections and ended up getting the 8.5 volts to the cell. The cell produced very little mist and bubbles in a bucket of water , but very little was a bit more than 0 so I assumed it was the cell. Best accounts is we think the cell is 8-9 years old so its most likely run its course.

I have ordered a replacement cell and we will see how it goes.

Thanks again for the reply

Cheers Ean

Hmm, never seen a pool run that high! The recommended level is around 3,000 ppm, 3,200 being ideal. Run it at 5,000 and the tile grout will rapidly start to fall out.
As for voltage: some Hayward chlorinators are up around 24 volts, but they must only be used with a compatible cell, and the controller will have a digital readout of the voltage.

Please keep me posted I have an Davey Es 16 having low output at present , I was considering replacing the cell but they aren't cheap. I am considering which chlorinator to replace it with at present.

I did a google search , after market cell for mine $159 delivered, sure its not genuine but local bloke quoted $440 + GST for genuine. Chlorinator is prolly 10 plus years old , after market will do just fine.

There aren't many chlorinators run below 4000 and some have higher recommended levels. And these salt levels are usually at around 20 deg C when the temp goes below this the salt level needs to be increased to stop the electrodes wearing away too fast.

That is why the low salt light comes in on many chlorinators during winter down here.

And for those that care it is very rare to get chlorine output once the water goes below 10 deg c

Many chlorinators I come across seem to run at 24 volts but I haven't been measuring them all.

Most chlorinators need a compatible cell to operate efficiently, and I know of one type of chlorinator that has variable output and can be adjusted to work with different size cells

Thank for that, most of the cells I have seen for the Davey chlorinators are around $500 +. Did you get the cell off Ebay ?

No - a heap of pool suppliers came up on google , so I just went thru until I found 1 with what I wanted. I can find out who it was if you like.
