Men!
I have a 300 gpd RO (3 x 100 gpd membranes) that brings the tds from the mains water supply down from 400 – 450 to 3 – 5 ppm.
Has anyone manage to match those tds figures with the larger 4 x 40 RO.
Thanks Nick

Those are figures I currently dream of mate.
oh noes, I've become and window cleaning nerd!
Please can you post pics and details of your system?

Sorry, but I can’t post any pics as I don’t know how.
My RO system is bog standard:
10 inch sediment filter
10 carbon filter
3 x 100 gpd RO membranes
Water pressure 75 - 80 psi
There is no need for DI as the tds are low enough to clean with.

Hi Nick hows it going mate!
I have twin 40 40 HF5 with ionic carbon/sediment filter and ionic softner. about 60psi and incoming tds of 300
my ro produces 001 after a flush out then about 12 hours later it may rise to around 004 or 5 we only use resin in the summer time. the RO doesnt produce as well then.

No problem cleaning with a tds above 000?
A few on here insist on having zero and I thought that was the norm tbh ?
Mines just gone to 001 and I was gonna change the resin in the week!
If I can get away with it for a bit longer then great

no problems with cleaning at 001 if you are under 10ppm u are fine even if it goes over it aint a problem but i always keep it under 10

my 40/40 runs at 55psi and get 386tds down to 3-10tds

Cheers appreciate that
If you can get away with upto 010 Why the fuss with new ionics ppb ?
I must admit I've cleaned with tds of 005 before I realised and fully expected a few call backs!
Cheers :)

you will save very little letting your tds rise above 001 buy could cost you a lot more

tds over 0 aint a problem , keep it under 10 its cool ive seen results at 005 tds and 000 its the same

tds over 0 aint a problem , keep it under 10 its cool ive seen results at 005 tds and 000 its the same
what is the saving between the two ? And how often do you have to check the water between then ?

i dont think the saving will be great, however i know that it makes 100% no difference in results therefor no need to worry if it creeps up ,
i see where you are coming from as i used to change resin when it came to 001 my logic was its a small price to pay same as yours infact but as my time in window cleaning
developed i realised it makes no difference at all so no need to worry if it creeps up
