This lack of use of the hot and cold water systems in such properties raises the possibility of increased levels of legionella bacteria and the associated risks that this is also able to bring about too. A regular flushing regime is proven to control Legionella bacteria levels but a stop-start approach to flushing does more harm than good. This is for sure the main use for this type of specialist system. |
Stagnant water favours Legionella growth. To reduce the risk you should remove dead legs / dead ends in pipe-work, flush out infrequently used water and in general make sure you do this in an ongoing manner too. Stagnant water is a breeding ground for Legionella bacteria so this is where and how you need to be ahead of the game to make sure you are able to ward off the presence as well as the risk of legionella in your property. Legionella can multiply in hot and cold water systems. Removing or flushing infrequently used taps can significantly reduce the risk of legionella.
Ensure that your water system is safe to use after a prolonged shutdown to minimize the risk of Legionnaires' disease and other diseases associated and linked with legionella. After all there are a number of these. Flushing is used as a method of preventing Legionella bacteria from getting to be able to spread. In terms of spreading, it really can spread like wildfire if it isn’t managed or treated in the correct way. Legionnaires' disease could potentially spread through toilet flushing, which releases invisible "plumes" of contaminated water into the air. Legionella bacteria can cause respiratory illnesses and this too is why and how it is vital to kill off the presence of legionella sooner rather than later.
During the summer months there is an increased risk of the proliferation of legionella bacteria in Legionella water systems due to higher ambient temperatures. As we all know, in the last year or so with the COVID pandemic and with lockdowns coming and going, we have had to make sure we are all more on the ball when it comes to the management of legionella. A water system which hasn't been used for more than seven days can increase the potential for microbial growth of Legionella. It needs to be taken very very seriously and not as an option when it comes to being on top of it from a management point of view.
