got my ro unit and tds meter yesterday and i'm a bit confussed with the tds reading i'm getting from my tap water. i live near the south downs and though my tds reading would be about 500 because of all the chalk but its only 250.
to any one else living around portsmouth or southampton whats your tds reading and what does ppm stand for?
-
ppm
parts per million i think, as how many parts of say chalk to water, or something like that
do i sound like i know what i am on about ??? ???
;D

Ok Quick glossary for you chaps.
TDS = Total dissolved solids (minerals generally not just chalk etc)
PPM = Parts per million
250+TDS = hard
100 or less TDS = soft
After the R/O your reading will be between about 5 and 20 and then that goes through your DI (de-ionised) resin beads to bring it to zero.
In a hard water area flushing your R/O prevents it's performance deteriorating quickly and disconnecting the feed from the R/O to the resin chamber for a couple of minutes (at the start when the R/O is bringing the TDS to a low figure) will save on resin usage.

thanks carl, after i asked the question i read the instuctions like you do and it was in there :D.
it also says don't use it on water above 90ppm for it could damage the meter, oh well.
have you change over yet carl?
Thanks Malc

i only know ppm as lokk after a swimming pool, so that comes into play [ps chalk was an example]
was thinking of a post that brings all wfp q's into one post explain prosses and probs, from mains to the drip on the sill! ya get me?
on the lady front tell her lokk at my bank balence in 6 months. if she has that much respect for you! i mean that in a good way to you! it has its problems yes! but so does a job!! but here you call the shots and get rid of the problems!

If you're using RO water - that's OK.
PLEASE PLEASE DON'T DRINK DI WATER It is definitely not good for your body.
