Concealed plumbing done right — pressure-tested before it’s hidden
CPVC and PPR concealed lines with proper slopes, accessible valves and a pressure test before walls are closed.
Concealed plumbing looks clean, but every joint inside the wall is a future leak if it isn’t made and tested properly.
RennovEN lays out supply and drain lines with correct sizing and slopes, fits isolation valves where you can reach them, and pressure-tests every line before a single tile goes on.

Diagnosis
Why it happens
Untested joints
Lines closed without a pressure test hide weak joints.
Wrong pipe for hot water
Pipes not rated for hot water soften and fail near geysers.
Poor drain slopes
Flat drains clog and back up.
