    extractor fan isolator switch

    If I am not mistaken there is no requirement for having fans permanently operating. I could have vents over all windows and keep them shut, and could have extractor fans in utility rooms, kitchen, bathrooms and keep them all switched off.

    Broke a gas pipe

    The ground is sloping upwards to the left of the photo. There is a terrace/flowerbed on the left of the photo and a retaining wall (which I am rebuilding). They originally passed the pipe "under" the terrace. I removed part of it and exposed the pipe. Without the flowerbed the pipe is above...

    Broke a gas pipe

    The glove was used to stop any dirt going into the dead part of the pipe in case they needed to connect it back. On the live side of the pipe we used a yellow end cap fitting I luckily had lying around. But gas pressure is very low, I think it is like 60 mbars before the gas meter compare this...

    extractor fan isolator switch

    And why do we need a utility room fan, come what may? We do not cook in the utility and we have window and door.

    Broke a gas pipe

    SGN said are coming tomorrow to disconnect this gas pipe completely and dig out a new path to service the neighbour (as it should have originally been). I hope they fix it tomorrow! Currently they left it with barriers all around (exactly where I am digging my new wall foundations).

    Broke a gas pipe

    No tape, nothing. The ground is sloping upwards. The pipe was at ground level if it were not for some flowerbeds hiding it. I tried to take some quick photos before the SGN guys tried to move it. As you can see the right side of the spirit level, this is where it obviously is at ground level...

    Broke a gas pipe

    Digging my front drive to put foundations in for a retaining wall, cut through the neighbour's gas pipe (yellow). Pipe is completely in my land and to make matters worse it is dug in very shallow, and I have been planning to lower the ground levels at that location. Can I request SGN either...

    extractor fan isolator switch

    My BCO has demanded a fan if the bathroom is new, regardless of a window, and said a fan is not needed if the bathroom has a window and it is old (for example refurbished as part of more general work). To me, it sounds like a very grey and discretionary area. Especially paragraph 3.31 3.31 If...

    extractor fan isolator switch

    I have installed a fan in the utility room because building control have asked me for it. The fan comes on with the lights and has a timer overrun. I have put a double wall switch on the wall, one button is the lights + fan, the other is fan on/off (disconnects the fan's permanent live). The...

    Bathroom venting

    Can I close the door "I promise not to use it" ? Or, "I promise not to use it until a fan is fitted" ?

    Bathroom venting

    I have a small bathroom and next to it a small guests toilet. They are not vented because they are in the middle of the house downstairs. I need to arrange for final inspection and not sure what to do about this. We have other bathrooms in the house and not really use these two, but I suppose...

    Wiser Home not very accurate and slow

    Yesterday I installed a Wiser HubR and a bunch of radiator thermostats (12). I keep a few rooms completely shut as we do not use them, and the real temperature in those rooms is about 16.C, but the radiator thermostats show 18C and 19C. The radiators are off, the doors are closed, there are no...

    Pump overrun while valves are shut

    I have a "Worcester Bosch Greenstar 8000 Life 40kW Regular Gas Boiler" Worcester technical support have told me that it is not possible to tell the boiler to increase flow temperatures. We even discussed if it might be made possible with a new boiler motherboard. Which does not yet exist. I was...

    Pump overrun while valves are shut

    Thanks, yes "an auto-bypass" seems to be it. And I presume it is an S plan. Two independent 2-port valves, in parallel, one valve controlling the CH loop and the other controlling the HW loop. The two valves operate independently of each other. They can be both open or closed or any...

    Pump overrun while valves are shut

    Could anyone please offer some advice? I have : a conventional boiler, one pump, two valves (CH and HW), one room thermostat, one HW cylinder thermostat and one timer module. When the room or the HW thermostat opens, immediately the corresponding valve shuts off, while the main pump is...

    Seeking flexible tap connector with 22mm internal diameter

    Thanks. I found in my storage some short flexi tubes but with large diameter and have used these. I did not use the flexi tap connectors. I do not know what the ones I have used really are for :-)
