Sorry I'm lost?? It's 29, then it's 0, then it's 9? All the same water through one di? Sounds like a duff tds meter for a start. As don't have a di vessel can only go on what I've read before about riser tubes and such.

Ye it cones out 00ppm thtu di once it goes thru the pipes it creeps up lol

You have tap mixing with pure through your di head. Your riser tube needs to be a tight fit.

If it's one of those di heads from China you may find the 'o' ring in the head is cracked or come out!

Or check your riser tube hasn't gone oval shape at the top. If it has just cut that bit off until round and that will do the trick.

Are you using 2 di's or just one and what is the size of them ie: 11L, 9L?

But it comes out at 0ppm from di ? So di is fine?
