I've noticed on 2 different occassions some kind of brown substance in my 2008k bicarb pump inlet. Not sure but maybe it's the paper from the F bicarb bags. Anyone else seen this? I don't know how it could get past the white disc filters. And it sure doesn't seem like a substance that could come from the coilies. We have central bicarb.

You still have paper bicarb bags from Fresenius? Ours started coming in plastic months ago....and they suck!

We're not using the bags either but we were about 2 months ago. We do stick the wand in vinegar so something might be up there. Anyone else see this?
Thanks

Look into the bottom og your vinegar bottles. About 10 years ago the supplier (F) switched to a cheaper vinegar that evidently wasn't filtered and every bottle had "mother" in it.

Thanks Chuck,

I know about "mother" and you're right. I tell them to check for that and they miss it a lot. When this happens, both of those white disc filters can be seen as darker in color. But the color of what I've seen is a brown color and I've only seen it at the inlet of 2 bicarb pumps.

Maybe a piece of cardboard fell into your mix tank or was in the bicarb to begin with and was shredded up by the pump. I have seen that happen several times.

I too have found small pieces of paper/cardboard in bicarb powder. After speaking to the manufacturer it was determined to be packaging material that some how got into the powder during the manufacturing/packaging stage.

Henry,
I have had a similar problem with a brownish "gummy" substance in my bicarb pumps. It was coming from internal degradation of the blue coiled tubing we use. It was purchased from Medical Solutions International and they claimed to have never heard of the problem.
If it's not in the filter, it's coming from the line, post filter.
I plan on replacing my tubing at PM's to avoid future issues.
At this point I do not know why only the bicarb line is affected or what is causing the substance to break away.
It is not biological, but rather a chemical breakdown.
Bisecting the tubing of an affected machine should help verify.

I think you're right Just a Guesst it was the blue coiled lines from them. We are changing them yearly now. Wish I knew why blue only though. Seems like worst is the machine that gets bleached the most (isolation). Thanks
