How to tell whether a blocked bath waste is local or connected with a wider drain problem.
Start with the bath waste
Hair and soap residue can collect close to the plughole or trap. If the bath alone drains slowly, that is a common place to investigate.
Compare other fixtures
If the basin, shower and toilet are also affected, the restriction could be further down the shared waste pipe or drain.
Use caution with cleaners
Avoid mixing drain chemicals or opening a trap that may contain chemical cleaner. Do not force metal tools into fragile fittings.
Persistent problems
If the bath repeatedly backs up despite local cleaning, a plumber or drainage contractor may need to check the pipe run and fall.
Describe the problem clearly
Mention if water returns through the shower, if gurgling occurs, or if trouble began after building work.
