Title: Flow restrictions 4040 ro
Post by: Adam Daly on November 09, 2018, 07:30:11 am

Just bought a 4040 membrane and housing  but can’t seem to find anywhere that recommend the best flow restrictor or where to get. I assume I need one? Thanks

THANKS FOR INPUT PEOPLE!

Dont need a flow restrictor, use the gate valve I assume it came with (red* turny/twisty tap on the waste pipe)

*disclaimer, other coulours may exist.

My gate valve has a 4mm hole drilled in the valve body

Same here - altho I made it slightly smaller at 3.5mm - ex pure freedom set up but I like it as you have it open to flush and just close it to get the correct ratio of pure/waste. no measuring or adjusting the the gate valve

I have a gate valve as mentioned ( with no hole drilled ) plus a bypass pipe attached before and after via 2x t pieces and a second valve between them. Set the gate valve to optimum ratio and open or close the bypass to flush or produce pure.
