Service-Specific FAQs

What types of piping materials do you use for commercial installations?

For clean water supply lines, we use fusion-welded Polypropylene Random Copolymer (PPR) or copper pipes, which resist chemical corrosion and high temperatures. For sanitary drainage and waste lines, we use heavy-duty schedule-40 PVC or High-Density Polyethylene (HDPE) joined by butt-fusion.

Do you design storm drainage and rainwater runoff systems?

Yes. Our design division performs local peak rainfall runoff calculations based on roof surface area. We size and install high-capacity storm gutters, vertical downspouts, and underground sand-traps to channel rainwater away safely.

What leak testing do you perform before backfilling or dry-walling?

All supply lines undergo hydrostatic pressure testing at 150 PSI for a minimum of 2 hours, checked with calibrated gauges. All gravity drainage lines are tested by filling the stack with water (head test) to check every joint for leaks before walls are closed.
