Brilliant ! thanks very much to all, this is the way I'll go

Four holes and yes, I can get into loft area directly above ceiling Thanks all David

i'm upgrading downlights in plasterboard and need to make existing 60mm holes 75mm for new downlights with same centres. i've got right size hole saw for drill but how do I make them bigger ? thanks

thanks ianmcd - I have a 1999 Suprima 80 with latest circuit board and microbore 10mm to most of rads. Works well, if expensive on gas. Water flow is good but I have a pressure-reducing valve before my softner in kitchen so rising main to loft tanks is <2 bar I think. Will this all work...

Hi, I'm about to have my loft converted to a bedroom and WC and have specified a storage area / tank room for existing cold water tanks and CH header tanks. Beginning to wonder if I might be better off moving to UV solutions at same time to avoid lots of tanks in Loft (I have 3) House is...

After some time the boiler starts to work correctly and shows 70 C at pump and 45 C near return. I suspect the 45 is low but because of boxing above boiler I cannot get a thermometerany closer. Yes - initially he set it too high but then reduced it to the lower rating for Suprimra 80 as...

thanks Gassafeman The gas valve was replaced 18 months ago for a new part and was fitted by a CORGI boiler specialist. Is it time to call out Heat Team or BG?

Hi Agile Using clamp-on dial thermometers I see 60 deg C at input to pump (about 5 meters from flow side of boiler) and 45 deg C at a tee drain off cock directly above boiler and connected to return pipe (closest I can get). Pump is running on "speed 3" and I have 16 rads of different sizes...

My suprima 80 doesnt have a flow switch and there's none fitted - only the APS connected - thanks anyway

Thanks Dave The pump continues for about 30 seconds to 1 minute after the boiler has cut out - long enough for me to run from downstairs utility to upstais a/c and monitor it running for a few seconds ! From cold, I set air thermostat to max, advanced boiler programmer to continuous...

Hi My suprima with the new PCB kit intermitently cuts out after about 4 to 8 minutes of running then goes through the auto reset sequence before restarting. A rapid flashing red led (4 per sec) is shown which I think means air pressure failure - fan stopped. Water temp at the pump gets to...

88mm was a typo - I meant 80 mm. Idea was to cut a letter box shape directly over the pipe exposing enough copper to splice in two t-pieces and the bypass valve with compression fixings. Thanks for the advice - I'll cut a bigger hole in the plasterboard. Back of kitchen unit pulls out...

Hi - I want to fit a water softener into a standard kitchen cupboard adjacent to the sink due to lack of space directly beneath the sink. Access to waste, overflow and power is ok. Rising main to loft header tank is more difficult as it runs horizontally behind the drylining in parallel...

Hi - I want to install a tapworks softener in my loft to supply softened water to cold water header tanks for basins, cisterns,showers and hot water tank as I have no room in kitchen near the rising main. Plumbing feed and supply off rising main in loft will be easy since lots of room next to...

[PLAN B - use old colour cable and avoid all these problems... Thanks both - where can I buy old cable for reasonable cost - I thought it was banned? A guy on ebay wants £15 for 10m of old three-core+earth plus £10 P&P ! Think I'll use blue and brown and a 90p B&Q yellow sticker !

Hi I'm adding a new light and switch in a bedroom to existing 1.5mm red and black lighting circuit with plenty of spare capacity. A new 4-way junction box will have both red and black T&E and blue and brown T&E plus earths. Do I sleave the new switched live blue wire with brown or red...

Wow ! seem to have kicked-off a bit of a debate ! Thanks BAS for the responses. The microwave "appliance" in question is a Neff built-in combination microwave oven and is physically screwed into a kitchen unit. It is 3KW device and has an ordinary 13A plug. I don't want to have to...

Thanks guys. To be clear, I'm ONLY interested in doing this properly and safely and will happily call in a Part P registered electrician to inspect and approve the work. My question was more whether it was dangerous or in any way wrong to have two isolation swtiches - one after the other -...
