Drainage in Sant Joan Despí: what lies under the floor
In houses and terraces in areas such as Centre, La Mossota and Residencial Sant Joan there are bathrooms on several floors and the system runs down to a manhole or the sewer connection. We check every run, leave accessible manholes and, where winters are cold, bury outdoor runs deep enough to protect them.
Before opening the floor, in homes in areas such as Pla del Vent, Torreblanca and Les Begudes we mark where each fixture goes and measure the distance to the stack. From that we work out falls and diameters: the WC on its larger pipe, and basin, bidet and shower into a shared branch.
We visit the home, locate the stack and pipe routes and give you a detailed written quote; a site manager coordinates plumbing, floor and tiling. We also renew drainage in nearby areas: Cornellà de Llobregat, Sant Feliu de Llobregat and Esplugues de Llobregat.

Frequently asked questions
01Internal drainage renewal in Sant Joan Despí: which areas do you cover?
We do this work in Sant Joan Despí, in areas such as Centre, La Mossota, Residencial Sant Joan, Les Planes, Pla del Vent, Torreblanca and Les Begudes, and also nearby: Cornellà de Llobregat, Sant Feliu de Llobregat and Esplugues de Llobregat. Before starting we visit the property and prepare a detailed written quote.
02What is a drum trap and why remove it?
It is a box, usually made of lead, under the bathroom floor that collects several waste pipes. It blocks and ends up giving off smells; today it is replaced by a trap on each fixture.
03Can I move the toilet or shower?
Yes, as long as there is enough fall to the soil stack. On the visit we measure the route and tell you which layout will work.
04How is this different from replacing drains?
Replacing a drain covers one specific fixture. Renewing the drainage replaces the whole internal system, from every fixture to the stack or manhole.
