An existing water loop

Hydronic radiant floor repair in Aurora

Repair means the tubes, manifold, circulator, or mixing valve already in the house are leaking or not moving water. It is not a new floor design, and it is not a furnace repair.

Find the leak before you open the floor

A wet spot on a slab can be a radiant loop, a domestic water line, or even a drain. Leak detection matters here because opening a floor is expensive. Ask how the loop will be isolated from the drinking water and from the other zones. A manifold valve that will not close is a smaller repair than a tube under tile.

A circulator that is hot and silent, or a zone that never heats, can be the pump or the control. Controls can be electrical. This page does not describe wiring. A boiler that will not fire may be gas. Use the gas page only as a boundary: leave if you smell gas, and do not expect steps.

When it becomes a new install

Adding zones or replacing a whole floor of tube is installation. One manifold gasket is not that project. No Aurora radiant-repair ordinance was retrieved.

Questions to settle first

The floor is cold in one room. Is the tube broken?

Not yet. The manifold valve, the actuator, or air in that loop can leave a room cold with the tube intact. Ask for those checks before anyone cuts tile. A pressure test on that zone tells you more than a guess.

There is a wet stripe on the slab.

It might be the loop or a domestic pipe in the same floor. Isolate the heating zone and see if the leak stops. Leak detection is the page for finding it. Do not jackhammer on a hunch, and do not assume it is the sewer.

Can the same person fix the boiler and the thermostat wiring?

Ask. Gas appliances and line-voltage controls are not automatically the plumber's scope, and this guide gives no wiring or gas steps. The quote should name who does each part. Ask them to write that limit into the quote before you compare it with another company.

Is a repair a new radiant system?

No. Repair keeps the tubes you have, unless they are failed and being replaced. A new layout, new zones, and a new floor are installation. Make the quote say which. Ask them to write that limit into the quote before you compare it with another company.
