Hi Mike
We test a sample of water from flat taps and the temperature of water at the tap in our flats annually.
There is a low risk due to combi boilers in place for most flats but our trustees prefer to err on the side of caution.
Our plumber does some quarterly checks on one hot water cylinder for us – flow and return temperature – and annual water samples and drain down, as recommended by our professional legionella risk assessment plus a cold water tank check annually on water temperature and condition of tank.
All the best
Vanessa
