Plumbing Checklist for New Homes: What to Plan Before Tiling and Painting

### Building It Right From the Start

Hacking finished Italian marble or imported wall tiles to fix a leaking elbow pipe is every homeowner's nightmare. Follow this construction checklist:

1. **Choose the Right Pipe Class:** Insist on SDR 11 CPVC pipes for all concealed hot and cold water supply lines, and ring-fit SWR PVC pipes for sewage and drainage. 2. **Perform 10-Bar Hydrostatic Pressure Testing:** Before any brick chaser wall is plastered, pump the plumbing lines to 10 Bar pressure for at least 24 hours to guarantee zero leaks. 3. **Plan Adequate Pipe Gradients:** Sewer pipes must have at least a 1:40 to 1:50 downward slope towards external inspection chambers. 4. **Install Dedicated Soil Vent Pipes:** Extend vertical vent stacks at least 3 feet above your terrace roof to maintain atmospheric pressure and eliminate toilet trap gurgling.
