Slow RO flow?? BACKFLUSH??

[Reef Reaper]

Dear fellow members,

Hope everyone is Ok from the blizzard!!!

I got a quick question. My ro/di flow has slowed down significantly. The sediment filter is probably getting dirty, but does anyone backflush their systems? I was wondering if it was worth getting a backflush kit. Thanks for the info and help!

Hi Philip
I do use the backflush kit but I am not sure if it makes a difference. My R/O water seems to come out faster when my cartridges are dirty (maybe it bypasses them)

Yes you should get a flush kit it will longen the life of your membrane

The flush kit just allows a rinse either prior to or after you make water. If you are not constantly using your RODI ie. make water and store... Then you probably want to get a flush kit.

Sometimes it slowes down due to the colder water !!

I never thought about the colder water. Do you think the colder water really makes that much of a difference 'saltwaterinbrooklyn'?

It does for me , I have had water production slow down quite a bit

You wouldn't need to worry if you had a booster pump... :p

+1 absolutely!!

water production rate drops 1.4% for every degree below 77deg

My water production slowed down at least 40% since the weather got cold. I have it hooked up to the faucet instead of under the sink so I can control the temperature that goes into the unit. After figuring out that it might be due to the cold water I adjusted the water going in to approx 75 degrees. Now it produces much faster.

The cooler the water, the slower the output but greater rejection, the warmer the water, the higher the output but less rejection.....

Well your cartridges can have a huge effect on your output. The thing to look at is the pressure that is going through the system.

The pressure on my unit had dropped to about 25 lbs. I replaced the membrane and nothing. My sediment cartridges were changed and nothing. Finally I changed my Carbon cartridge and HOLY COW! Pressure shot up to 65 lbs..

So your cartridges may have a big effect. Yes the cold water does also, but make sure that the system is running correctly.
