Hi Tony I've measured the flow through internal stop cock every 0.3 bar or so, adjusting the flow from the outside tap to give the desired dynamic pressure. I get: Pressure [bar] Flow [ltr/min] 3.0, 0.0 2.7, 5.1 2.4, 6.0 2.0...

Hi guys My newly built house is connected to the water main by about 30m of 32mm o/d MDPE pipe (roughtly 26mm i/d). At the outside tap near the stop cock, the measured static pressure is a shade over 3bar. If I leave the gauage on the outside tap and turn on an indoor tap my dynamic...

Sorry for the confusion - I always thought PRV was Pressure Reducing Valve

Hi steelmasons No typo. The tank is a Danfoss DWH-300. It comes with a 24 litre expansion vessel. The spec is (typed from the datasheet) Max water supply pressure 10 bar Pressure reducing valve 3 bar Expansion valve 6 bar Expansion vessel charge pressure 3bar Operating pressure 5.5 bar...

Hi guys I have a quick question regarding the correct pre-charge pressure for an expansion vessel (24 ltr) on the cold supply of a DHW cylinder (300 ltr). As measured after a combined 3 bar PRV + 6 bar safety relief valve assembly, the static pressure of the cold supply is 2.5 bar. The...
