Why is Tap Water Cloudy and What Should You Do?

Did you turn on the tap and instead of clear water, a milky liquid flowed into your glass? This is a relatively common problem that raises questions for both homeowners and renters. Fortunately, clarity is usually just a few simple steps away.

Why does tap water become cloudy?

When tap water suddenly turns whitish or cloudy, it is often due to microscopic air bubbles that have entered the water pipes. Pressure changes in the water network or local repair work can create a situation where air mixes with water under pressure. The Health Board and water companies confirm that such air bubbles are completely safe and disappear from the water quickly.

Another common cause is water network maintenance and pipe flushing, during which natural minerals found in the piping system, such as iron and manganese, move around. Water hardness, or high mineral content, can also cause cloudiness. Calcium and magnesium can make the water appear slightly murky and accumulate in household appliances over time.

A simple glass test to identify causes

To determine the actual cause of water cloudiness, a simple test is sufficient. Fill a clean and transparent glass with cold tap water and let it sit on a table for a few minutes. Carefully watch how the water begins to clear.

If the water in the glass begins to clear from the bottom upwards, it is due to tiny air bubbles that quickly escape from the water. This means the water is completely safe to drink. If the water remains cloudy even after sitting for longer or sediment settles to the bottom of the glass, the cause is sediment or minerals coming from the pipes. In such a case, it is worth letting cold water run for, say, three to five minutes when drawing drinking water, so that the water remaining in the pipes can flow out.

Cold versus hot water and pipe maintenance

Sometimes cloudiness occurs only when the hot water tap is opened, while the cold water is completely clear. The milky appearance of hot water is usually due to sediment inside the boiler or water heater, or a reaction of the heating element with mineral-rich water. Experts recommend always using cold tap water for daily drinking and food preparation, as hot water that has sat in the heater can accumulate unwanted compounds.

If the cloudiness appears only in one specific mixer, the problem may be a clogged aerator or screen at the end of the tap. Cleaning the aerator is a quick household task that anyone can easily do. If you want to avoid larger technical problems and keep your home's plumbing in good condition, it is worth reading practical advice on how to prepare your plumbing and heating system for winter. Also, simple ways to prevent blockages at home help ensure the smooth operation of systems.

Homeowner and tenant responsibility and involving a specialist

When living in a rental home, it is important to know how responsibility is divided between the owner and the tenant. Minor maintenance work, such as cleaning tap screens and careful use of appliances, is the tenant's daily task. The building owner, however, is responsible for the overall maintenance of the building's technical systems and the operation of heaters and plumbing.

If tap water does not become clear within 24 hours, if the water has an unusual smell or taste, or if visible sediment comes from the plumbing, you should immediately notify the apartment owner or contact the water company and a plumber. Properly functioning technical systems and clean drinking water ensure a safe and comfortable home.
