TDS of the RO output water is now up to 45ppm, after approx 150 gallons. I bought replacement filters and an in-line TDS meter to try to figure out why the filters are getting used up so fast.

Let us know what you find out. I always disconnect mine after using it (which is only used one every two weeks or so. I fill up a 50 gallon garbage pail with RO/DI water). Then I store it until needed next. I use those blue pugs they give you to keep stuff from leaking out (and getting in) while it is in storage.
My output is still 0, and I have had it longer than you.
Can you point us to the inline TDS meter you decided on ?
Thanks

Mileage will vary based on the tds level of the water going in. What is yours currently?

I fill up a couple of 1-gallon jugs, every other day. How do you get water out of the trash can?

This is the TDS meter. I'll let you know if it's any good. There weren't many other options that I could find.

Almost 350ppm going in. I believe that some filters fail before others, and then they ruin the other filters down the line.

Here is my post about what I do: post382605.html#p382605

The trash can is on a patio that is about 5 feet higher than my plants.

Oh cool, that is a good setup. I don't have a patio, but could probably put a trash can on some cinderblocks. Hmm...

The higher it is from what you are watering, the greater the water pressure will be. If you don't mind a slow trickle, it only needs to be a foot or two higher. If you are using a watering can, you can just prop it higher than the can and not worry about it.

I get my water out the old fashioned way - I take a 1 gallon bucket and reach in and scoop out water as I need it.

Thanks for the URL - I’ll be anxious to hear how the meter works for you.

Not a fan of the meter. My TDS readings were way off, compared to two handheld meters I tested. The plastic case is not sealed, so the circuit board may be easily affected by temperature/humidity. Anyway, I returned mine.

I ended up buying some valve kits so I can take a sample of water in between various stages and test it manually. I also read that the RO membrane should be flushed after each use, so the valves will make that task easier.
