Musty and earthy taste and smells

Experiencing musty and earthy tastes and smell in your home?

Musty and earthy taste and smells

If your water smells musty ensure that your internal hot water pipes don't come into contact with cold water pipes and that all plumbing valves, fittings and materials are WRAS approved.

Any sections of pipe or taps which are used infrequently should be flushed through to allow fresh water in. This can be done by opening the tap and allowing the water to run for a few minutes.

Works in your area

Water supply issues can often be caused by works being carried out in your area. Enter your postcode to see if there are any roadworks or incidents that could be affecting you.

Musty water that tastes or smells earthy can be caused by the growth of harmless micro-organisms such as bacteria and fungi in domestic pipework. It’s particularly common in sections that have a low usage or are subject to local warming, where hot pipes come into contact with cold pipes. Valves and fittings containing rubber materials are also particularly prone to these growths.

Sometimes, it is caused by very low amounts of naturally occurring substances released by algae growing in raw water reservoirs. These substances are not normally thought to be hazardous to health at the concentrations at which they are found. Our Water Treatment Works are operated to minimise these substances and we carry out daily checks on the smell of the raw and treated water.
