How do you change your water ?

[EmilyB]

Hey Mike, where were you while I was trying to sell it ?

Anyhow we did keep it, for our RO/DI and salt mixing. Never did figure out how to go beyond that, but if you want to have a look at it for design, feel free.

I have a 2nd sump dedicated to water changes. When I want to change, I shut off flow into/out of this sump, marking the level of the water in this sump (25 gallons). The main sump and tank continue to run normally.

I open the drain valve on the 2nd sump and the sump empties. I use a rag to wipe the sump clean of any "stuff".

Meanwhile, new SW has been mixed in advance in a 50 gallon mixer. A quick throw of a valve and the mixer pumps new SW into the empty sump.

Total time: 5 minutes. (4 of those are because the drain valve is slow to drain the sump!)

Right now, I'm not heating the new water. I just let it enter the system cold.

How did I miss that ? Being one of your better customers over the years I still have everything that I ever got off you. Thanks I might take you up on the offer if I'm out that way.
