Plumbing and Re-Piping

A home-run manifold gives every fixture its own valved line back to one labeled board. It is a better way to plumb a house — behind a regulator.

Red hot, blue cold, one valve per fixture, every run labeled. Ten years from now somebody can shut off one bathroom without shutting off the house.

The pipes you never see

A manifold is a fine idea.
Behind a regulator.

Every fixture on its own labeled run, and one valve you can reach without a flashlight.

A home-run manifold gives every fixture its own uninterrupted line back to a single labeled board — no buried tees, no guessing, and one valve per fixture instead of crawling under the house with a flashlight. It is a genuinely better way to plumb a house.

It is also the moment to say the quiet part: if you are in a high-pressure zone, whoever installs this must reduce your pressure first. A beautiful manifold fed at 160 psi is a beautiful manifold operating at the outer edge of its rating for the rest of its life.

The same principle governs everything you bury in a wall. A wall is open exactly once in a generation, and every decision that has to live inside it gets made in that window — or it gets made later with a saw.

A wall-hung carrier going into open framing. Everything about this decision — the height, the rough-in, the access panel — is cheap today and expensive the moment the drywall goes on.

Before any of this, know your incoming pressure. A manifold, a new fixture set and a re-pipe are all rated assemblies, and on this hill they are commonly fed at a pressure past what they were built for. Read the pressure page first →
