Your local water authority provides a minimum water pressure of 0.7 bar. However, at different times of the day, this pressure may increase depending on demand.
<h2>When should I contact my water authority?</h2>
The water authority is responsible for the water up until it reaches the boundary of your property — anything within your boundary is for you to mend.
If your water pressure problem is a result of an internal issue, such as a leaking pipe or using multiple appliances at once, it is your responsibility to rectify the issue.
If your water pressure has suddenly dropped or altered, it could be a result of an external issue that your water authority is responsible for. Contact your local water authority to establish if there are any leaks or works in the mains water supply.
