My RODI unit is not very old and has not had all that much water through it but the output rate is half what it is rated for which is 5 gallons/hr.

I don't have a clue what to check or do.

Suggestions please.
 
Usually in the winter when the water gets cold output drops. What is the psi going into the ro/di

What does the first filter look like? Is it white, or orange / brown? It could be clogged up.
 
I don't know how to measure water pressure from the hose connection. My house has excellent water pressure though. The waste water comes out of its tube well.

I checked the filters and they all look new to me. I don't know how to check the membrane.
 
How long is the hose that comes from the water faucet to the ro unit? I believe someone suggested for another member to take the hose if long enough and coil it in a 5g buck with room temp water. The room temp water is way warmer than the incoming water from the faucet. I bet that you see a increase in water production.
 
WOW! The temperature makes all the difference in the world. The temp is back up for summer and the water flows just like it was new.
