Blocked Drains in Preston

Start with what is backing up

Open the nearest accessible chamber and check the water level before running more water. If that chamber is full, look farther downstream; if it is clear and only one fitting is affected, start with the branch between the fitting and the chamber.

Check with United Utilities where the problem may be shared

If several homes on the same run are backing up, the chamber nearest your house may simply be the first place the problem shows. Check whether the affected section is shared before arranging private work.

If neighbouring properties are affected, contact United Utilities before assuming the blocked section is privately owned. Their current guidance is available at United Utilities.

If the same drain keeps blocking

If a Preston drain has already been cleared more than once, keep the measured distance to the blockage. CCTV after jetting should focus on that point and show whether a joint, roots or a narrowed pipe are causing the recurrence.

Choose the repair after you have seen the defect

Ask the contractor to show exactly what has failed and how far the damage extends. One local joint defect may not justify replacing a whole run. A badly displaced or collapsed section, however, may leave no route for an internal liner.
