Manifolds

Manifolds are the central hub of modern plumbing and hydronic systems, routing water from a single supply to multiple fixtures or heating zones with precision. By consolidating distribution, a manifold improves control, balances flow, and makes service faster and cleaner. Fewer branch connections mean fewer potential leak points, and individual shutoffs let you isolate a sink, shower, or radiant loop without taking the whole system offline.

You’ll find supply manifolds for domestic hot and cold water, as well as hydronic manifolds for radiant floor, baseboard, and snow-melt applications. Popular configurations include PEX manifolds with crimp, clamp, or push-fit outlets, and premium brass or stainless steel manifolds with integrated ball valves. Hydronic manifolds often add flow meters, balancing valves, purge/drain ports, thermometers, and air vents to dial in each loop. Polymer options offer corrosion resistance, while brass and stainless deliver durability under higher temps and pressures.

Choose features that match your project:
- Port count sized for today’s needs with a margin for future expansion.
- Connection type compatible with your tubing (PEX, copper, CPVC) and tools.
- Built-in isolation valves for each circuit to simplify maintenance.
- Drain and purge points for quick fill, flush, and seasonal service.
- Clear labeling tags or clips to speed troubleshooting.
- Manifold cabinets for tidy, code-compliant installations.

Installation tips: mount level and secure, keep lines organized with color-coded hot/cold, pressure-test before closing walls, and insulate hot-water and supply lines to cut heat loss. For radiant systems, balance loops using the flow meters and confirm air elimination through the automatic vent.

Valve repair is straightforward with the right parts. Stock replacement O-rings, stems, cartridges, and handles to fix drips, stiffness, or seizing. Periodically exercise shutoff valves, check union connections, and re-gasket as needed. A well-chosen plumbing manifold paired with reliable valve components delivers quieter operation, consistent temperatures, faster installs, and easier upgrades across residential and light commercial projects.
