Help and advice

Understanding your water quality is essential for making informed decisions for your home.

UK drinking water is amongst the safest in the world and at Hafren Dyfrdwy, we always work hard to provide the best quality service possible.

From time to time, you might notice a change in your water’s taste, smell or appearance. This is often nothing to worry about and in our experience, can usually be resolved by running your tap for a few minutes.

If your water smells, tastes or looks different to normal, you can diagnose and solve your water quality problem using our self-help guildes.

There are a few reasons why you may have low pressure or no water.

It's usually caused by emergency repair work near your home, such as when a main supply pipe has burst, but it could also be a problem with the pipes in your home.

If you have no water or low pressure, you can check for known issues in your area to see if there is anything currently happening that could cause a supply issue.  


If you keep fish, it’s important you are able to get detailed information about the water you’re supplied so you can take steps to keep your fish in the best possible conditions.

Many pet fish are naturally at home in rivers, lakes and seas – quite different conditions to the treated, clean water that comes through your taps from us.

Because of that, you may need to alter the amount of some substances in the water you keep your fish in.

For example, chlorine is extremely toxic for fish. You should always make sure you remove chlorine from water you use to fill your tank.

Always make sure you speak to your local pet shop, aquarium or vet to understand what conditions the fish you keep are healthiest in and whether you need any specialised equipment or plants to create the right conditions for your fish.

Special interest magazines like Practical Fishkeeping are a great source of advice too.
