This is probably a bizarre issue to have as I can't work out the reason but basically over the last couple of weeks I've noticed the water in all 3 loos really seems quite whiffy and stagnant. It appears to coincide with the water level looking oddly low - I've no idea what could have caused this!?
Loos are cleaned regularly and are given a go over with toilet brush (sinful I know!) and bleach probably every other day. Any marks in the loo are dealt with at the time with disposable toilet brush thingies so the quick clean with bleach/toilet brush are literally just to freshen up.
Any idea what could be causing this it's really driving me mad!
