About this deal

This inlet pressure, in general, is too high and variable for domestic systems to operate correctly. it is a pressure reducing valve (3 bar) on the main inlet feed with a 6 bar safety release valve, it is the safety release valve that is dripping into the tundish, it was doing this approx. I would imagine the safety release valve same as the one on the actual hot water tank are there to act if pressure goes to high. li>

  • Specially shaped diaphragm to give accurate pressure regulation in response to changes in downstream pressure. I'm struggling to think of anything that would cause the 'trapped' domestic side to increase like this.

    Unvented heating system has a caleffi pressure reducing valve, 3 bar with 6 bar safety release valve.

      I'm afraid I don't have much knowledge of these items - I do have a PRV fitted in my own home (and a Caleffi as it happens) but I'm not aware of it having a safety release valve on it. Comprising a pressure reducing valve, a pressure relief valve and check valve, fitted all together in a single inlet control multibloc valve. The unit comprises of a manifold containing a pressure reducing valve, a cold water balancing port with check valve, a check valve and a preset pressure relief valve. Do you have a anti-'water-hammer' vessel fitted in a place where it could get really hot during the day, enough to cause the pressure to climb?You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. This includes a specific connection for a balanced cold water take offs and a dedicated connection for an expansion vessel. Since there are three 22mm pipes to hook up and the 15mm outflow you would probably otherwise need a 'union' to be able to make the connection to the tundish. Pressure reducing valves are devices which, when installed on a private plumbing system, reduce and stabilise the inlet pressure from the water mains.

      It has been reconfigured from the original in that the 15mm outflow pipe is an easier connection due to it now being a swivel connector.The charge in the expansion vessel should be the same as the incoming pressure that is set/ controlled by the pressure reducing valve. Caleffi is a decent make, I understand, but these fellows - well, the safety-release-valves - are prone to allowing a drip through after they've been activated. It is designed to protect the unvented cylinder by controlling the main supply pressure that goes to the tank and is not designed to regulate the pressure of the entire property. The item may be missing the original packaging or protective wrapping, or may be in the original packaging but not sealed.
