Hi All
Hope some one can answer my question
When conducting Monthly Temperature Checks on hot water taps, do all hot water taps have to be checked? i.e. if you have 8 wash basins in the ladies toilet would all 8 have to be checked?

Hello Naomi,
In short, no. If the water is coming from the same source then you only need to test 1 tap in each location but I would do a different tap each month.

ACOP L8 STATES REPRESENTATIVE NUMBER OF TAPS ON A ROTATIONAL BASIS. THERFORE CHECKING 2/3 AT A TIME WOULD BE FINE

Thank you for this info, unfortunately I have a new problem.
How do you go about testing if the hot water doesn't come from the same source? The building has 7 different mini boilers!!
The other problem is we have to run the tap for at least 1 minute before testing the temperature, by the time we have done this the boiler is having to refill again (as so small) and we do not get a true reading? any ideas??
Thank you

Could you not say that the fact you are regularly flushing via the tap and emptying the boiler is reducing the risk of legionella .... and eliminate the requirement to measure the water temperature?
It would of course depend on the frequency of flushing but the fact of emptying the tank/boiler must eliminate the space for the bacteria to multiply?
All would need to be risk assessed.. of course!

I don't have the guidance to hand at the moment, but I though the idea was that if hot water was being relied on as a control it should reach the specified temperature "within" the time not after the time.

Two things. When testing hot water systems, then temp (50 c) should be reached WITHIN one minute note AFTER.
Testing is at 'sentinel' taps i.e. the first and last taps from the tank and/or any other tap that you consider to present a particular risk. Again as previously stated above, you won't go far wrong by testing taps n rotation.
If you have numerous sources then you should test each source.
However, depending on the size of the calorifier (tank) and the draw off for each then you may find (as Tony Campbell has said)that you have little to worry about. If your 'boilers' are merely serving taps, then I would suggest that the risk is pretty minimal anyway as there is little opportunity to create an aerosol.
Hope this helps a little
Phil
