testing filtering system and DI resin

Testing the water quality and outp0ut of filtering system !

Anything above 4.00 is unacceptable

Seems I am going through a lot of DI resin and have just ordered a 25 litres bag,

I am metre reading the water as it comes out of the pre filters and then monitoring the water quality as it exits the DI filter and then the water quality as it exits the containers

It seems the filter membranes may need changing after a years usage
