Frequently Asked Questions
What is a plumbing rough-in phase?
A rough-in phase is the first step in setting up the plumbing lines. It is set up before the insulation, drywall, or flooring of the home. It is generally installed underground or in-wall.
Are the pipes tested?
Yes, professional plumbers ensure they use high-grade pipes for your plumbing lines. They also run tests on the lines to catch leaks before the flooring is done and the walls are closed.
What kind of pipes are used?
Professional plumbers use PEX or copper pipes for the water supply. For the drainage system, they go for PVC or ABS pipes because these kinds handle waste well.
How are leaks prevented after the final fixtures are added?
To prevent post-installation leaks, plumbers use braided stainless steel supply lines. These lines don’t crack easily under vibration. They also install individual shut-off valves for quick isolation. After installing these high-grade lines, they run a live water test to check for leaks.
