Greenish debris coming from hot tap
We've had issues for ages now with our water supply. The mains supply
itself contains sediment, but the hot supply is giving us problems we are baffled by. The worst problem is when more than one hot tap is opened and demand is higher around the house. What happens is that fairly large particles, which I can only describe as being similar in appearance to snots (no joke!) flow out with the water. I've been wondering for a good while as to what the hell this stuff can be. You don't really see it with just one tap opened, or demand being lower, but its an unpleasant thing to have in your supply right? I've talked to plumbers, they don't want to know really (because I presume they have no clue how such crap could form in the hot water cylinder). Live in Dublin btw, and never seen this in any house but mine. Would appreciate input, cheers. |

It does seem to be some sort of bacterial growth in the hot cylinder, if it were isolated to a pipe length, it would be flushed out eventually.

We've had our current hot water cylinder for almost four years, and I know it occurred in the previous one too (that cylinder ended up leaking, I wonder if this stuff is corrosive too). |

At least you'd eliminate one major possibility that way. I agree its probably bacterial growth, with a firm hold on part of the system walls - hence it dislodges under high flow. Safer than bleach though, is water purification tablets (the type for using in drinking water in dodgy parts of the world - buy them in Boots) - chuck a whole packet of them in the header tank. |

I actually just finished performing another cleansing of the system, using some Milton sterilising solution. Possibly won't be enough to kill very much in the cylinder though... I don't fancy using bleach, could cause issues if someone accidentally uses water too soon afterward. The cylinder I have doesn't seem to have a stat unfortunately... though the water can get hot enough to really burn your hands, so I would think that wouldn't be too much of an issue. |

JimK sorry for double post :~)( with the bleach thing you could probly calculate the likely time/"number of cylinders worth of water" to dilute however much bleach you put in down to "nothing". Size of cylinder + level of water in header tank + rough guesstimate of length of pipework involved = total amount to treat then factor down (using bleach instructions/ideas from on here) how much bleach to put in header tank to treat, how much to draw off to get it into cylinder, how long to leave, how long to dilute down and drain out?? Cheers JimK |

with the bleach thing you could probly calculate the likely time/"number of cylinders worth of water" to dilute however much bleach you put in down to "nothing". Read Treloar for how to do it properly: Quantities, times, clean out afterwards. |

I've been wondering for a good while as to what the hell this stuff can be. You don't really see it with just one tap opened, or demand being lower, but its an unpleasant thing to have in your supply right? I've talked to plumbers, they don't want to know really (because I presume they have no clue how such crap could form in the hot water cylinder). Live in Dublin btw, and never seen this in any house but mine. Would appreciate input, cheers. Drain the hot water cylinder completely and see what comes out last. R |

Have you tried cleaning the taps from the tap end? I do this when I remember usually every couple of years and I get some (although not green) junk out. The tap end is probably more exposed to heat and air being in the heated house as opposed the the attic. Just my pennies worth. |

None presented the following explanation : how would I drain down HW system btw? Turn the water off, where it goes into the header tank or tie the float up - then turn all the taps until the all go dry. But make sure there is no source of heat into the cylinder first. That'll leave the hot cylinder full, look for a drain point at the base of the cylinder where the cold enters, or failing that you may need to undo the threaded connection at the top where the hot exits, and syphon it with a hose. |

And no, the active ingredient in them is not chlorine. Firstly and for the bewilderingly pedantic amongst us, I am refering to Andy's mentioned Sodium dichloroisocyanurate, and the earlier mentioned sodium hypochlorite and your assertion that neither use chlorine as the active:- wiki advises that sodium hypochlorite: releases free chlorine when dissolved in water. sodium dichloroisocyanurate : mechanism of action is the release of chlorine in low concentrations by constant rate. Do you know differently? (with references please) Cheers JimK |

I actually just finished performing another cleansing of the system, using some Milton sterilising solution. Possibly won't be enough to kill very much in the cylinder though... I don't fancy using bleach, could cause issues if someone accidentally uses water too soon afterward. Really I'd use a couple of litres of man bleach rather than a little baby bleach. Re cylinder temp, even set to hot might not clear it as usually the bottom of the cylinder doesn't get so hot. Worth a try though. So is leting the hot go stone cold for a day, some bugs that like heat cant survive cold. The cylinder I have doesn't seem to have a stat unfortunately... though the water can get hot enough to really burn your hands, so I would think that wouldn't be too much of an issue. Sounds like its heated by a gas or oil boiler, in which case temporarily upping the boiler thermostat setting will make the water hotter. (Not the room stat.) I'd start with bleach, its the only thing that'll reach every nook & cranny. Adding washing up liquid might help it penetrate the slime more. Notes can be posted over the taps for the day in case anyone forgets. NT |

In the USA some connection has been made between that and Legionnaires disease! There were a series of postings on a similar North American (Canada- USA) quite recently; although nothing as dramatic! Here the Dept. of Health require 160 deg F. for safe dish washing and when we operated a school cafeteria for some 30 years their inspectors would test the water temp. 'Snot' growing in the hot water sytem sounds extremely unhealthy/ unsafe? Suggest urgent action. |

I menat usually. Not always. That bottle you have in the bathroom cupboard for cleaning, that everyone calls bleach because that is what is on the label? It's probably NaClO. Usually (and I mean the word precisely) if you look at a container marked "Bleach" that is what is in it. Not always. Major industrial processes - paper springs to mind - often use different chemicals to reduce environmental impact. Now perhaps you'd like to consider how your post helped anyone. Andy |

I think you've had some good advice regarding both clearance of the present situation and how to minimise problems in the future. Sadly, the main cause is coming in via the mains and somehow that grot has to be stopped. I take it you have had no joy with the Water Dept.? |

I'm convinced that in one house I was in, things improved a great when I lowered the temperature and after continued use. There I also got snots of what I presume was lime which regularly blocked a shower head. |

I've done that lots of times. The hot water take off is at the top of the cylinder, with an overflow up to the header tank. All that happens is that the pipes to the taps drain down and air is sucked down the overflow to replace the water. The cyclinder is left full of water, as other have pointed out. MBQ |
