Hello guys
I don't do a massive amount of wfp work my round is probably 90% trad 10% wfp, all work is commercial. I have a Merlin RO and replaced carbon filter bout 3 months ago, and a fellow windy has said I should flush it

News to me !! Not sure about it at all tbh.
I have landed a job that's guna be using somewhere near to 15,000 litre of water, and can use there external tap, so happy days, it's filling as am working, my water is coming out of Merlin at 007 at the mo so it's doing its job and changed my sand yesterday.
Am just ordering a spare set of membranes and carbon filter as I don't want to come un stuck half way through the job.
But am now left thinking why what & how is flushing the RO going to help or change the affects of the Merlin
Any help would be appreciated
Matt
