Blocked Drains in Birmingham
In Birmingham, start with the nearest chamber you can safely inspect. If it is clear while one sink is slow, the problem is likely to be on that branch. If the chamber is full and neighbours are backing up too, check the shared sewer before booking private work.

Start with what is backing up
With an accessible chamber, compare what happens before and after the suspected section. A full chamber followed by a clear one pins the blockage between those points. If the chambers are clear and only the kitchen sink is slow, the underground main may not be involved at all.
Check with Severn Trent where the problem may be shared
Extensions and later alterations can leave old chambers buried or move kitchens and bathrooms away from their original connections. If the route is unclear, tracing the drain can save a lot of guesswork before jetting or digging begins.
If neighbouring properties are affected, contact Severn Trent before assuming the blocked section is privately owned. Their current guidance is available at Severn Trent.
If the same drain keeps blocking
Where a blockage comes back in the same section, note how far the rods or jet travel before they meet resistance. Once the run is clean, a camera at that distance can reveal a step, root entry or heavy scale that would otherwise be missed.
Choose the repair after you have seen the defect
Do not agree to a long replacement simply from a brief camera description. Ask how much pipe is damaged and where it lies. A short defect may be repaired locally; major displacement or collapse usually needs the affected section exposed.
