No mold PVC
Using some clear flexible 1/4" ID PVC tubing for a warm water jet and
after two months, the inside is getting moldy. Seems insane. Is there some non-mold flex tubing available anywhere such as Home Depot? |

Is there some non-mold flex tubing available anywhere such as Home Depot? Run cleaner water or sanitize the tubing periodically. Tubing is just providing a place for mold to grow. The spores are in the water. |

I would suspect that if a chemical were added to the plastic to retard mold formation it would not be allowed for food contact. |

I had some 1/2" clear fish tank hose long enough to reach the sump, so I cut the vertical PVC on the furnace and stuck the hose in, taping it up with duck tape. It's been working for 5 years now. I assumed it was scale build up clogging it, but when I remove the old PVC I'll cut it up and find out, and let you know. Now I have an excuse to do it. |

Nice thing is that PVC was easy to repair with just a couple of bucks for glue and sleeve. The AC condensate goes in first and down the line the humidifier overflow goes in. The clog was past the humidifier and overflow was there. |

I doubt it's scale, where would the lime come from? That should be distilled water hitting the pan. I suspect it's dust off the coils combined with biological growth. In a constant wet environment all sorts of nasties can grow. |

I defer to you. I am certainly no expert in that. WAG... I'm not an expert either but did do a couple of years of R&D on plastics for food contact but mold issue never came up. I would suspect that if a chemical were added to the plastic to retard mold formation it would not be allowed for food contact. You are right. News flash! Don't drink my Kool-Aid. -- Tekkie |

If this is algae, it is growing in the water, the tube is just where you see it. Use opaque tube like PEX and the problem will go away. Yes and I see they sell black PVC tubing but if you ignore it it may build up to a blockage.* I had this happen on the small PVC drain piping on my central AC last year. The only problem with black PVC would be that if algae did grow, I would not see it. So I am going back to my original tubing. It is translucent but not clear, It seems to block enough light as to prevent growth of algae but if any did grow, it's just clear enough that that I could see it I wish I could have seen what was happening in my PVC pipe in the basement. There is no light in the furnace room to prompt growth and I go in and check things every couple of days and found water on the floor instead of in the French drain. The pipe was too clogged to wash out with bleach and too many bends for a small snake so I had to cut it and take it apart to clean it. The HVAC guys will hook up their wet/dry vacs and suck it out. It usually collects at low points or elbows. Cannot recall but might have tried it with my shop vac and did not get a good connection. Pipe was pretty clogged up. There are adapters sold specifically for that. https://www.amazon.com/Diyvac-DV4/dp...EM/ref=sr_1_4? dchild=1 &keywords=hose+adapter+for+air+conditioning+drain+ line&qid= 1594929458&sr=8-4 -- Tekkie |

Should also have an alternate drain set up for just this reason possibly with a condensate pump and float valve. I think you are at my stage of life if it occurs again, you will deal with it then or not... -- Tekkie |

Now I have an excuse to do it. I doubt it's scale, where would the lime come from? That should be distilled water hitting the pan. I suspect it's dust off the coils combined with biological growth. In a constant wet environment all sorts of nasties can grow. Don't drink the Kool-Aid... -- Tekkie |
