External Drainage and First-Fix Renovation, St Albans AL1

A full renovation job in St Albans, AL1 ran across several weeks this month — starting with external waste pipe drainage, moving through first-fix plumbing, and finishing with a new Vaillant boiler installation. Jobs like this are done in stages deliberately, each one setting up the next.

Getting the drainage right first

External waste pipe drainage was the first stage, since it sets the fall and connection points everything else in the house has to tie into. Getting this run correct before any internal pipework goes in avoids the far more disruptive problem of having to re-route first-fix plumbing later because an external connection doesn't line up.

First-fix plumbing and the new boiler

With drainage sorted, first-fix plumbing followed — soil stack and copper pipe distribution run to every room that needed it, all completed before plastering and flooring went down. A Vaillant boiler installation was carried out as part of the same job, including a magnetic system filter fitted at first-fix stage to protect the system from day one.
