Do you sell the boiler fill / pressure-reducing valve on its own?

No. Boiler parts are supplied and installed by our licensed technicians as part of a repair — we do not sell parts for individual or DIY purchase. We diagnose the fault, supply the correct genuine OEM fill / pressure-reducing valve, and install and test it as part of a certified repair.

How long does a fill / pressure-reducing valve last?

Typically 8-12 years. Lifespan depends on water quality, maintenance and how hard the boiler works. Annual servicing helps it reach the upper end of that range.

Which boiler brands do you carry fill / pressure-reducing valves for?

We install genuine fill / pressure-reducing valves for Navien, Viessmann, IBC, Weil-McLain, Lochinvar and more across Greater Vancouver.

What the Fill / Pressure-Reducing Valve Does

The automatic fill valve (pressure-reducing valve) tops up the heating system from the mains and holds it at the correct fill pressure. A failed fill valve either lets the system lose pressure or overfills it, tripping the relief valve.

It reduces mains pressure to the boiler's fill set-point and adds water as needed to keep the system topped up, with a check function to prevent backflow to the potable supply.

We supply and fit the fill / pressure-reducing valve as part of a complete boiler repair or new installation, and inspect it during annual maintenance for homes across Greater Vancouver.
