As title , me being the idiot 

I only run small RO's , only 250L needed per day , i was running 2x 50GPD units and was getting more than enough , however one of the membranes went south and i was left with one 50 GPD , if it runs constantly i can keep up just about .
But the backflush / flow restrictor is starting to leak and will need sorting .
What i want to do is run a 75 GPD constantly , which will give me all i need , but upon looking it seems i need to replace a few bits .
What i use now is this

I just turn the black bit and it backflushes , i assume the new flow restrictor will just go in its place , but what i am not understanding is ...... how do you then backflush the membrane

I just cant see how its done , sorry for the stupidity of me

Treat yourself to an update   

Doug at daqua is cheapest I've found👍 for Ro's

Does ro man type units upto the big boy stuff.

Not 100% sure what you mean but if the new flow restrictor is the basic ones with no tap. All i used to do is put a John guest t piece either side of the flow restrictor with a tap between them and when you want to flush the membrane just open the tap. But to be honest i wouldn't even worry about it and dont even know if you can 75gpd flow restrictors.
Personally  i would stick with 100gpd day at least then in winter when the product flow starts to drop you will still get enough for what you need.

As above ^^^

You’ll need to put a t-piece before and after the new restrictor.
Connect them with hose so you now have a bypass on the restrictor and the fit a tap (1/4 inch, push fit) on this bypass.

Close the tap to produce and open it to flush.

Personally I’d fit one 100gpd membrane and then do as above. They’re cheap enough

Thanks for the replies chaps , that all makes sense now with the T pieces , i have always bought the ROs local which came with that auto flush bit on .
RO man do the 75 membranes and flow restrictors , but thinking about it , it would probably be wiser to go 100 GPD route as its better to have too much than not enough isnt it !
Thanks for the help , will get it ordered up asap .
