    Which is flow and return ?

    I cant see any markings on the new rad , and the instructions only describe the wall mounting procedure . I vaguely remember fitting one a while ago which came with a blanking plug , which had to be fitted somewhere to determine flow and return ( if this makes sense?) . There`s nothing like...

    Under Floor Heating Stopped Working

    Under Floor Heating Stopped Working

    Thanks very much for your reply . If the display screen is still present on the thermostat , would that rule out an RCD or fuse problem ? There is an isolation switch , so I`ll switch it off until its sorted . I was hoping against hope it would come back to life - its bloody freezing in there...

    Rendering over Concrete

    I`ve just had a concrete base laid for a pond and am going to render it for a smooth finish prior to painting . Is it advisable to prime it with PVA or similar first to aid bonding ? and should I use a bonding agent in my rendrer mix

    Rendering Pond walls

    I`m currently building a concrete block pond . I`ll be rendering the internal walls next , prior to painting . Just wondered if its possible to use 1 coat of render as long as the walls are flat , or does it have to be 2 coats . Also , what is the minimum thickness required ? Any...

    Concrete Pond Base Construction

    Hmm .. I`m starting to think that might be the way to go . I`ll probably be making unneccessary problems if I go with the original idea . I`m still planning to lay it myself , though ! :) Just need to decide whether to use a strengthening mesh or fibres
