Drain Water Coming Up in Shower

Water or sewage coming up through your shower drain is a distressing and unhygienic problem that indicates a significant blockage or failure somewhere downstream in your drainage system. The shower is often the lowest drain point in the house, making it the first place backflow appears.

What to Look For

• Dirty water rising through the shower tray when the toilet is flushed
• Sewage smell from the shower drain
• Water bubbling up through the shower plughole
• Problem worsens when the washing machine drains
• Other drains in the bathroom also affected
• Water rising even when the shower isn't in use

How We Diagnose the Problem

We inspect the shower waste connection first, then use CCTV to survey the underground drainage from the nearest external access point. The backflow pattern tells us whether the blockage is local to the bathroom or in the main drain run. We check for collapses, root blockages, and fat buildup.

How We Fix It

We clear the blockage causing the backflow, then investigate and repair the underlying cause. This may involve jetting, root removal, relining, or excavation depending on what the CCTV survey reveals. We ensure all fixtures drain correctly before leaving.
