Converting a system to sealed or setting up a new one from scratch needs the same handful of components every time — a way to bring the system up to pressure, a gauge to check it, and a relief valve to protect against overpressure. The Tesla Sealed System Filling Kit brings all of that together in one compact, pre-assembled unit, saving time sourcing and fitting each piece separately.
The manifold connects via a 3/4" union to the expansion vessel and 1/2" BSP to the system pipework, with a 3 bar safety relief valve and integrated pressure gauge built in. A flexible filling loop, complete with double check valve and isolators, allows the system to be topped up directly while preventing backflow into the mains supply. When commissioning, Tesla's own guidance is to set the expansion vessel pressure to 0.2–0.3 bar above static system pressure before connecting.
Bringing the filling loop, gauge, manifold and safety valve together as one pre-assembled unit genuinely saves time compared to fitting each part individually, and reduces the pipework needed in a tight plant room. A double check valve on the filling loop is a compliance essential, preventing system water from backflowing into the mains supply during topping up.
