Post by: Clever Forum Name on February 01, 2015, 01:44:07 pm: My 450GPD this time of year takes around 9-10 hours. (400L holding tank)

No booster pump however i have 70-90 psi mains pressure.

475PPM - down to 6PPM then through twin DI's

Post by: Clever Forum Name on February 01, 2015, 02:08:06 pm: Flushed it properly ?

Is it just the feed from the RO going into the tank?

Any idea on pressure ?

Post by: Clever Forum Name on February 01, 2015, 02:35:48 pm: Do you know the pressure though?

Have you disconnected the RO from the Di to measure LPM ?

Flushed ?

Disconnect the RO producing tube and time how long it takes to make one liter LPM (liters Per Minute) That the pure feed going to DI

Pressure and cold will have a massive effect on it.

Post by: john63. on February 01, 2015, 03:20:49 pm: Yeah done that so it can be normal to take 15 to 20 hours
Title: Re: 350 tank
Post by: Clever Forum Name on February 01, 2015, 03:38:40 pm: I would say no as it's taking nearly twice as long as mine.

I would look into water pressure and look at LPM before DI

Does it have to go through di

Depends on what you are producing at i guess. I produce at 6PPM and still use DI (we get free resin though) I would hazard a guess at pressure is lower than mine.
