A reminder to double check your TDS

[P4dstar]

I’ve had a HM digital in line TDS meter for 3 years with no problems. I use double DI after the RO so when it rises to 1 I change the resin. Invested in an X-Line trolley this week so I decided to check the TDS coming out of it. At first I thought the reading of 8 was because the trolley was new. Double checked the van and it was reading 6. Long story short my out probe had stopped giving a reading. Checked this by switching the probes around so it was measuring pre resin and still read 0. We managed Friday on the water we had but have 2000 litres to throw away in the garage now ??‍ I’m more annoyed with myself as I’ve not only got handheld TDS meters as a back up but one of my pumps actually has a TDS meter built in and I left it too long without double checking!!

Personally would use the water if only doing maintenance cleans. The other option would be to dump half of it and dilute your 6 to 3.

You’ll be fine to use the water that you have stored. I use water up to 15ppm before I think about changing the filters/resin ??

I wouldn't throw the water mate, just use it as is, do you know anyone who does car valeting or pressure washing with a van mounted tank that could do with it

I agree with @Part Timer I would use the water, no way would I dump 2,000ltrs

I would be tempted to use it but just check the results are ok , if there is problems with it spotting , or as @Part Timer said dilute it down or put it through a resin bottle and it will be fine

Think I've used up to 10ppm before. No way would I dump 2000lts ?

I used @Part Timer’s plan. I washed the gutter vac, car and van and rinsed them directly from the tank. That worked a treat with the flood pump. Then I dumped a little and just purified on top. The tank reading is currently down to 4 and nearly full.

I think most of us have had accidents at some point. Mine was fairly recently using 20PPM without realising! No complaints though but far higher than I normally use (don’t normally go above 4PPM). Shows the importance of checking it regularly.

i check my tds as a matter of course as one of my end of day jobs after every fill of my tank.....anything under 010 will be fine for cleaning windows with....

get into the habit of checking it every day..it takes 2 seconds!i have 2 handheld tds meters.
