Vertical plumbing stack is installed after structure work is done

All the pipes for water supply, sewage, and drainage can be installed at two stages:

In new home construction plumbing, all the pipes for water supply, sewage, and drainage can be installed at two stages.

1. Pipes are installed when slabs are being cast. This is the method that is very common in builder floors/ villas, especially in Duplex House Design and similar low-rise developments. In this method, the pipes get buried under the slab, beam, or brickwork. In the future, if any pipe requires maintenance, it is a problem.

2. Pipes are installed after the structure, brickwork, and plaster are completed. This vertical stack plumbing is the method that is the default standard in group housing/ large residential projects, hotels, office complexes, etc. In this method, after brickwork is done, pipes are made to stand alongside the wall. This was done so that any future maintenance can be done easily.

Impact of following this method on builder are:

1. An increase in project duration and cost as scaffolding is required at times to make the pipes stand.

2. Concealment of pipes is to be done as per design in the front facade or courtyard.
