Mine in Manitoba was fine after the softener fed the ro unit. One think I never knew back then was the well was high in alkalinity, and with no DI removing on my ro unit, it was messing with my tank.

My water changes went down with the rest of the water. I assume my and others softener dumps a lot more salt in the septic system than a water change. I guess like Grizz, one could pump it elsewhere to be on the safe side.

I too am in Manitoba, my water is over 800 ppm but have no troubles as long as it goes through a softener first. All my water goes straight down the drain.

Grizz, which filter system are you using?

Kinetico?

We have a commercial RO, very expensive unit.

Nice, your own chlorination too.

Thanks

We are on well water, my RO has 2 prefilters, 1 carbon, 2 membranes and DI resin to get TDS to 0. Adding the second membrand really shortened the time it takes to produce water. I change the prefilters approx every 100g, carbon every 150-200g and DI resin every 800-1000g so yes I think this is alot more than people on city water. We are looking at putting an iron remover in our house.

I was on city water but had a septic system, after 10 years of water changes and such it never caused any problems. and when we had the inspection done when we sold the house they guy said it was the cleanest system he had ever seen, so.... who knows if that is a worry?

Depends on what kind of septic system you have, if its a pump out or gravity feed to a field. If you have a pump that cuts in on your wet side at a certain level and pumps out the tank you will never have any issues but still need to double up on your bacteria additive to break down solids.

If you have a gravity feed out to a field like I do, you need to be very aware of what goes down the drain in the form of liquid. Even when we have a house full during the holidays I have to check the level on the wet side to make sure it does not get to high and go over the weir that separates the solid's from the wet side. So water changes for me are a bit more challenging.

Also should mention that I checked up my TDS the other day with a brand new Milwaukee meter and it was a perfect ZERO!!

I had a gravity to a leach field. my tank was two chambers but had a pipe that spilled from one to another. when we first moved into the house we had it cleaned and inspected and also had a particulate filter/strainer installed on the first chamber side of the pipe. this was so that when there was increased water usage it would not allow solids to pass to the second chamber.

how much water do you change at a time? it would take a heck of a lot of water at once to pass solids, unless it is a old system and some one built a bigger house than it was designed for.
