Vancouver Tap Water TDS

GreenSpottedPuffer · #1 01-09-2009, 08:23 PM

I just bought a meter and tested it...10ppm. If its already this low, why do we even need the DI resin? I was running my RO without the DI last night and coming out the water was 0ppm. I am going to use it anyways but seems almost pointless.

I am impressed at how good our tap water is. I had heard it was low TDS but didn't think 10.

Actually here is an even better question. I started using the DI this morning and just tested the TDS of that water and its 25ppm!!! Why would it be 10 going in, 0 after the RO membrane and then 25 after the DI?

if any of the cartridges are new let them run for a bit then test the water
from what i remember the vancouver area does have a very low tds in the water compared to most places

Yeah I heard between 15-20 but I wasn't expecting 10. Although one of the J&L employees told me today that they test it and its always around 11ppm.

In Coquitlam, TDS is frequently lower than 10.

I'm not in Vancouver but Chilliwack and out of the tap the TDS is between 30-40.

Once through the R/O it reads 0 so I don't use the DI, seems to be a waste of money if I can get a TDS of 0 without it.
