Post by: billozz on October 11, 2009, 07:23:07 pm

guys,
help please, the tds on our system is 13 we have a pump to assist the throughput.....ie it pumps the water from tyhe tap through thr ro, this pump has packed up, also we have just changed the pre  filters can anyone advise if a drop in pressure would have this result or why changing the filters would affect it.
thanks guys

bill

Do you have a DI vessel in line while exiting the Tank?

sounds like it was your resin that needed changing then, so change that and exit through the DI . always better any way.

The highest TDS I have worked with was 005.
Is the 013 coming out from the tank or the TDS before the tank/DI?

Susan still isnt happy with the text though as the l's look too thick, someone from the printers told her on the phone it will be ok on the print, but she wants written confirmation so if they turn out crap we have a written gaurantee.
35,000 leaflets, it looks like we'll be having 30,000 leaflets distributed with a private company, 15,000 per week.
Just hope I can deal with the response. lol
