Problem with flow from RO

[Richard Taylor]

Hi. 

The flow rate from the RO into my tank has gone right down. It's gone down to around 20litres/hour. Normally it's 100. Flow from mains tap seems good. Normal amount seems to be coming out of the drain hose. Any ideas.

Have you looked at your membranes? They do clog with algae over time. Are you prefilters mucky, that may indicate algae and if so, it's time to change your membranes. In my experience, they only last 12h18 months depending on the local supply.

They can get blocked with the salts you're removing if not flushed regularly
