    External Socket Setup

    Whatever you attempt make sure the circuit has a 30mA RCD on it. The correct way is to use armoured cable, concentric cable or PVC cable with the same level of mechanical protection as armoured with proper glands and installed within the correct depth (1.5 feet), sand covering the cable...

    Cable query

    I would disconnect it from the socket, mcb/fuse, fused spur, junction box etc thats feeding it. If the cable is linking the ring together (should be 2 cables in each socket) then I would rewire the leg of the ring. I have seen concrete react with the outer sheaf of a twin and earth cable and...

    Bilge Pump Pressure

    The reason the valve is there is for mechancial protection in the unlikely event of the electronics going haywire (custom built 24 input, 24 output, 3 analogue input GSM controller) if this happens then there is a chance the pump will keep on pushing water, reach the float valve level right at...

    Bilge Pump Pressure

    Thanks for that...If you run them dry i.e they run out of water then they will die pretty quickly...where it says it will churn the same amount of water in the casing does this mean it will continuously push against the valve with an imense build of pressure? Or does the pressure divert back...

    Bilge Pump Pressure

    Thanks for the reply.. I am not looking to put more switches/sensors etc on the system as it is already built. I am wondering what happens if you block the output pipe on a bilge pump i.e does the pressure kind of back feed into the tank rather than continuously push and build up against the...

    Bilge Pump Pressure

    The system already has float switches for turning the pump on and off. The float valve is being used as a water inlet and for mechanical protection as the float is above the float switch that controls the pump. So in effect the float valve would only close when there is a problem i.e the...

    Bilge Pump Pressure

    Acording to what the guy who sold me the valve has just told me on the phone the float valve is rated Pressure - 0.05 - 1.0 Mpa (as of the Ebay description) From what hes told me this is the equivalent of 0.5 bar - 10 bar A normal UK tap is 1 - 4 bar acording to a plumber I have just phoned
