Something wrong with the water?
Here are a few tips on what to do and who to contact if there´s something wrong with the water. Low Pressure Have you checked to see if your neighbours have the same problem? When did the problem occur? Is the pressure low throughout the whole building? Check that spout strainers are not clogged (vinegar works well as a cleaning agent). Discoloured Water Do you live in a house or apartment? (If in an apartment, check with landlord first). Are your neighbours having the same problem? Does the problem apply to cold water? (If it is hot water only it is the landlord´s responsibility). What does the water look like? (Discoloured, gritty, cloudy (white))? Try flushing for 5 to 10 minutes. Sometimes your water may look different than usual. Listed below are some of the more common reasons and how to fix the problem yourself. If the problem persists, please report it to customer services on 020 971 300. Water is yellow/brown The water mains consist in part of iron pipes. Sometimes rust is formed in the pipes and comes loose, especially in conjunction with water leaks or work on the mains. It is often sufficient to open the taps fully and run the water until it clears. Let the water run for 10 to 15 minutes;if it remains discoloured please contact us. Water is white/greyish-white There is probably air in the water. The air has entered through the mains during work in the system. If the water is left to run for a while the air will disappear. It is completely harmless. Water is greenIf you have district heating there is probably a puncture in a heat exchanger. Heat exchanger water is coloured green specifically to make it visible. Contact your heat exchanger supplier. The water is cloudy/has particles We've probably either been working or repairing a leak in your area. If water has been turned off to your building owing to repairs, it can entail the dislodging of material in the mains when we turn the water back on again. This is not dangerous, but flush out as close to your water meter as possible — ideally through a tap in the cellar — so that you do not circulate the cloudy water throughout your property. Flush for 10 to 15 minutes; if the water remains cloudy contact us at customer services on 020 971 300.
Grit/particles in water
Probably calcium precipitation in the water. May sometimes cause shower strainers to clog. Use vinegar to clean the strainers. Certain improvements can be achieved if it is possible to lower the temperature in the hot water heater to 65 Celsius (not lower owing to the risk of legionella bacteria).
