DRAINAGE IN HAMMERSMITH

Drainage & blocked drains in Hammersmith

Hammersmith’s Victorian terraces are closely built and often extended, so reaching the drain can be the hardest part of the job.

Drainage in Hammersmith

The terraces of Brackenbury Village, Ravenscourt Park and the streets off the Broadway were built close together with small yards and narrow side returns, and the drainage runs through them accordingly. Inspection chambers end up under decking, inside kitchen extensions, beneath patios and occasionally under a neighbour’s paving. Before anything can be cleared it has to be reached, and in W6 that is often the part that takes the time. A camera survey confirms where the runs actually go.

Many of these houses have also been extended or had basements dug out. Side-return kitchen extensions are common on these terraces and often go over the original drain run. Basement conversions add pumped drainage below the level of the sewer, which introduces sump pumps and non-return valves, all components that fail and that leave a basement with no drainage at all when they do.

Common drainage problems in Hammersmith

Chambers built over or paved in

Extensions and patios covering the only access. Locating and reaching the chamber is often the bulk of the job.

Extensions built over drain runs

Side-return kitchens often sit over the original clay drain. Lining is often the most practical repair.

Basement pump and valve failures

Below-sewer basements depend on pumps. When one fails there is no gravity fallback and the basement can flood.

LOCAL QUESTIONS

Drainage questions in Hammersmith

Common questions about drainage in Hammersmith, answered for the kind of property you find there.

Usually. In W6 it is common, because side-return extensions have often been built over the original drain runs. There is normally another access point upstream or downstream we can work from, and a camera will confirm the layout. Where a run genuinely has no access at all, adding a new access point is sometimes the sensible long-term answer.

Not necessarily. A below-sewer basement drains through a pump and a non-return valve, and if the valve has jammed open the main drain can back up into the basement during heavy rain when the system is under load. That looks like a blockage but is a valve failure. Both are worth checking.
