    Fix Plasterboard to metal plate soffit

    I am in the process of replacing rotten timber window lintels in an old house. The new Lintel per Structural Engineer will result in a galvanised steel plate as the internal soffit which will subsequently need to be plastered. I was thinking of using insulated plaster board fixed with aerosol...

    Engine damage from incorrect oil

    Main Vauxhall dealer did an oil change on my 57 plate Vectra, but used incorrect oil (10w 40), instead of fully synthetic 5w 30. They have now changed it to correct oil, but suggested the only way to check for any damage or engine wear is to take engine apart and rebuild. Can anyone give any...

    As a result of an extension to the side of our house what was once an external wall is now an internal wall. There is no cavity fill. Is there any reason why I cannot now use the cavity of this internal wall to run cables? regards

    Which type of 2 port valve

    I have a system with 2 nos 2 port valves. The actuator heads are Sunvic, motor open and motor closed 5 wire type, rather than actuators that use a spring in one direction (presumably to close) and I guess only have 3 wires. Does anyone have any preference from experience for one type over...

    Boiler Modulation and weather compensation

    I understand the idea of boilers having their power requirements modulated by sensing either flow water or internal air temperature. I can also understand the idea that a boiler can modulate dependant upon external weather data ie Weather Compensation. But I don't understand how, if they...

    Ideal Mexico HE

    I am aware of various comments in postings here about the unreliability of Ideal boilers but most of them seem to relate to wall mounted Isar combis. I am looking to replace a 15+ year old floor mounted Ideal Mexico on a fully pumped vented system. I don't have the supply pressure for a...

    Cast Iron bath removal

    Any tips for breaking the bath up in to easily removable pieces. It is in a second floor flat. Only access via 4 'short' flights of stairs, not a lot of room. Is a hefty lump hammer the best tool or is there something else? I tried to break one up many years ago but I recall it wasn't as...

    Gas Fire ventilation

    I understand that a room containing a gas fire with an input greater than 7KW requires additional ventilation of 5sq.cm for every kw over 7kw. Does the size of the room not have a bearing on the amount of additional ventilation required? Instead of using an 'airbrick' through the cavity wall...

    8mm compression adaptor instead of olive

    I am about to replace old rad valves with Danfoss TRV's. The system is 8mm copper microbore. To fit the 8mm pipe the TRV's come with a brass adaptor rather than a separate olive. The adaptor is supposed to 'collapse' and seal against the pipe like an olive when tightened but it looks quite a...

    Tung Oil on stained windows

    I have read much on this forum about Tung Oil as an exterior window treatment and would like to use it on my Mahogany window frames. I have tried oil on its own on a test piece and it does not give me the depth of colour so I am thinking of using Hicksons Predec hardwood colour harmoniser as...

    I would be grateful for some help re the following: Where the floor area served by a domestic power ring main falls within the 100sqm max, does the recommended max 60m cable length refer to the total cable ring length from and back to Fuse board or half of the overall length because of the...
