Hi everyone
My current tds before di is 027, my tap water is 400 does this seem ok I have a 300 gpd ro, I moved property about a year ago where my tap tds was about 365 and I use to get 12 before di, I have changed pre filters today and still no change is this a sign of the membrane slowly going, it’s over 2 years old, any ideas
-
yes its on its way out, when mine was pushing 55out of RO its was time to change costing to much in resin, my tap water is 340 comes out of Ro about 12/15 when all is new no pump low pressure
-
Have you had these figures long? Or just recent? With you saying you have not long moved?
What's your tap psi? You might need a booster pump perhaps.
I use a 350gpd RO but my tap psi is very low and so I use a booster to take it to 70psi. My tap tds is close to 300 and after RO it's down to 009, so I don't bother with DI

I have a booster pump, it’s been like it for a few months I have always had the booster pump as both property’s had low pressure around 40 at both so now I’m 60-70 psi

Hi Stephen, have you tried giving the system a good Backflush for an hour or two occasionally, this normally helps
bring down the TDS.
-
Changing the membrane would be a good start but with the extra TDS I would say update the booster for pump for more pressure
