Pressure Pipe

Build a durable, leak-proof plumbing infrastructure for your pond and filtration systems with our range of high-performance PVC-U pressure pipe. Engineered specifically for demanding aquatic installations, heavy-duty pressure pipe provides the structural strength, rigidity, and pressure resistance required for underground bottom drain lines, high-flow pump returns, and filter manifold assemblies.

Manufactured from tough, unplasticised polyvinyl chloride (PVC-U), our pressure pipe is fully fish-safe, corrosion-proof, and designed to withstand substantial internal hydrostatic pressure and external ground compaction without warping or cracking. Available in standard imperial sizes ranging from 1.5 inch and 2 inch lines for pump manifolds up to heavy-duty 3 inch and 4 inch diameters for bottom drains and gravity feeds, these pipes solvent-weld securely to create permanent, watertight joints that resist root penetration and ground shift. Suitable for both buried pipework beneath pond bases and surface runs in filter houses, explore our complete pressure pipe collection to find dependable, professional-grade pipework engineered for long-lasting pond performance.
