Building on the steady stream of increases reported in late winter, the PHCP-PVF pricing environment has carried its momentum into early spring, with a new wave of manufacturer adjustments taking hold across key product categories. As previously reported by Supply House Times in its February–March 2026 pricing update, inflationary pressures tied to metals, resins and global supply dynamics continue to drive targeted increases rather than broad, across-the-board hikes.

The latest round of adjustments, effective from mid-March through mid-April, reflects that same trend, with manufacturers implementing measured increases across venting systems, brass and PVF components, thermoplastics, HVAC parts, controls and copper fittings. Notably, several of the largest moves this cycle are concentrated in plastics and fittings, including a double-digit increase on PVC and CPVC pipe, alongside continued upward pressure on copper and brass-based products, reinforcing a pricing environment that remains active, but increasingly surgical in how and where increases are applied.
