Internal drainage renewal in Granollers: how we plan it
In 1960s to 80s flats in areas such as Centre and Sant Miquel the original system is often still there: drum trap, lead or iron waste pipes and joints that already leak. We replace it all in bathroom and kitchen, up to the building's stack, before the new floor goes down.
The connection to the stack is the delicate part: in buildings in areas such as Congost, Granollers Nord and Primer de Maig we find cast iron, fibre cement or old PVC, and use the right adaptor for each. If the system has no venting, we add an air admittance valve.
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: Les Franqueses del Vallès, Canovelles and La Roca del Vallès.

Frequently asked questions
01Internal drainage renewal in Granollers: which areas do you cover?
We work in Granollers in areas such as Centre, Sant Miquel, Congost, Granollers Nord, Primer de Maig, Can Gili, Can Bassa and Tres Torres, and also nearby: Les Franqueses del Vallès, Canovelles and La Roca del Vallès.
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.
