Deionized water system

[dieselfan1]

I got it all hooked up and used it a couple times. I got a third sediment filter also. The DI does help some but I still have some spots. Not terrible but not spot free. The canisters leak where they screw on so I need to thread tape them. I noticed the resin is already turning brown. I may look into reverse osmosis I don't know yet.

I built myself a RO/DI system and although it works ok, getting a large enough volume of clean water through it is an issue. I think that is a problem with all "consumer" DI systems.

I have since modified my system to provide bulk water which I can then run through my pressure washer. Now I always have 30 gallons available.

This is only for personal usage... It would never cut it in shop environment.

I wonder if maybe the water is going through too fast to do much.

I used to use those filters above but they never totally removed the minerals from my water. It brought my TDS from 140s to 50s and it worked for a wash or two and then the filters stop being effective and gradually lost its filtering capability.

I finally bit the bullet and went with the dual tank On The Go Deionizer. I used it yesterday for the first time to fill up a bucket for a quick rinseless wash. 0-zero on the TDS meter. Can't wait to start using it with my pressure washer setup. Because these pesky black piano door pillars on the Durango will water spot etch just by looking at them.

Do you have a TDS meter? If not, you should get one. They're cheap... Just look on amazon.

Then you can measure the effluent and that is the only way you will know how well your system is working.

It's 440.

Would it help using softened water?
I'm using cold out of the laundry tub which I believe is unsoftened
I could add some hot so it's lukewarm.
I have no idea.

What is the effluent? What it is going in is irrelevant other than resin life.

Softened water still has the same TDS as the unsoftened water although the dissolved solids are softer and the resulting water spots wipe away easier.

Is the water leaking between the filter housing and the cap?
If it is Teflon tape is not going to fix the problem. The housing seals to the cap with an O-ring. Check to make sure the O-rings are in the grooves. Also check to make sure the O-rings have not flattened out or have any nicks or cuts in them.
When you replace filters do not use the filter wrench to tighten the housing, hand tight is all you need and will make the O-rings last longer and not flatten out.
Another tip is to use silicone plumbers grease on the O-rings, just make sure not to get it on the threads of the housing as this can make it nearly impossible to loosen up the housing from the cap after it sits for a while.

I recently used the Griots inline water softener and deionizer. I was skeptical because it seemed too simple but I used it when I washed the truck in direct sunlight and there were no water spots. It was easy to connect and it did not reduce the water pressure or flow.
