TDS meter reads .004 to .008

[jenglish]

How long are you letting it run for? mine has to run for a few minutes before it gets clean.

[nanofreak]

it's been running all day and it was at 5 its now at 3 since i moved the di filter

[jenglish]

hmm... maybe once the channel is defined enough you are still getting some bypass. I don't know what else to tell you besides 3 is better than 5

[nanofreak]

lol yea I hear you what about adding another DI you think I should be alarmed with 3??

[jenglish]

I wouldn't be alarmed by 3 myself unless you are dealing with the most delicate of specimens or using massive amounts of top off water. You coudl theoretically replace the second DI filter and see if that helps.

I am only running 1 DI filter

low pressure can cause membrane to foul resulting in high tds along with chlorine exposure or inadequate carbon filter replacement. depending on what your water pressure is (probly 30psi) most systems are designed to operate at much higher psi helping to keep the membrane clean.

[nanofreak]

anyone know where i can get a booster pump for cheap.

[nanofreak]

Here is the other weird thing. My waste line is full flow. The RO?DI line is a dribble. It use to be much more then this.

[Jadinop]

The colder the supply water is the lower the production rate will be. It's not uncommon for the output to drop off in the colder months.

[nanofreak]

Really thats interesting

[nanofreak]

It has been running most of the night the meter reads 008 right now I have good pressure the RO/di is a dribble. Mabye my water is so bad that the filters are exhausted.

+1

OK what do you guys think. The water with the unit off is still running out of the waste line until I shut the unit down. There is a trickle coming out of the RO/DI line does this mean that the filters are clogged and its bypassing the ro and going right out the waste side.

the water running out of the waste line is normal it's just the pressure built up in the system. and the colder the water the lower the production try a booster pump it will help alot this is the one i use. i have a 150gpd unit and with out the booster pump and depending on water temperature it would take 2 hours to make 5 gallons with the pump it takes an hour.
