What the drainage renewal includes
-
Planning the layout
We mark fixtures, pipe runs and falls before opening the floor.
-
Drum trap removed
We take out the lead drum trap and old pipes from under the floor.
-
New PVC system
Branch pipes sized and laid to the fall required by CTE DB HS 5.
-
A trap for every fixture
Basin, shower, bidet and sink each with its own odour seal.
-
Stack or manhole connection
A watertight joint to the building's soil stack or the house's manhole.
-
Water test
We run water through every fixture and check the joints before closing up.
Drainage in Castelldefels: what lies under the floor
Near the sea, in areas such as Centre, El Castell – Poble Vell and Muntanyeta, damp and salt corrode lead or cast-iron sections, especially exposed ones in courtyards and on terraces. We replace them with PVC and leave access fittings where they can be opened without breaking anything.
Before closing up, in homes in areas such as Montmar, Bellamar and Les Botigues we run water through every fixture and check all the joints. Where pipes pass through a ceiling void above a neighbour, we wrap them in acoustic insulation so the water cannot be heard.
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: Gavà, Viladecans and Sitges.

Frequently asked questions
01Internal drainage renewal in Castelldefels: which areas do you cover?
We work in Castelldefels in areas such as Centre, El Castell – Poble Vell, Muntanyeta, Vista Alegre, Can Vinader, Can Roca, Els Canyars and Montmar, and also nearby: Gavà, Viladecans and Sitges.
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.
