Sorry thought you were heeding faster flow out of the RO ? What’s the water pressure?
Cant quite remember but I think it was getting on for a bit less than 200 or a bit less, that’s direct from tap, before it gets filtered.. My old water vessel was refitted slightly wrong and leaked from the lip of the valve, but the new one I have has a higher water and filter cleaner , can’t remember what it’s size in but it does run slowly.
I can’t decide wether or not to fill in a filter system next to the tap and see if it goes through a bit quicker than the longer pipe , if it does, then I need to get a new garden cabinet to fit the two garden barrels I use to store water for the van tank.
