No, hence I ask questions on a DIY forum for helpful advice! I could probably find them out as I would do before I do anything and obviously I'll have a chat with my Corgi who will want everything doing to spec....

Thanks for all your advice. Yes I do have gas fires and hob these come from the meter currently in 15mm. As the house only has 15mm in at the moment I was asking if 22mm would be sufficient from the meter. i.e. the existing 15mm feeds teeed as soon as the pipe leaves the meter. I have...

Thanks for your replies, I asked the questions on here before I ask a Corgi as I obviously don't want to put their nose out of joint.... I want to work with them and do as much as possible to save cash as it is very very tight at the moment! :( Is there anything obvious I've missed is...

Hi, I am going to be installing central heating in my new house and just want to check if my proposals make sense. I'm going to get a Corgi in for a chat beforehand also to make sure they're happy with what I propose and are happy to commission the boiler. I'll do it in a list of what I...

To me it sounds like you have wired the booster into a permanent live and a switched live. Reason being, when the light is off the booster / splitter is getting it's live from the permanent live, but it's neutral is flowing through the bulb. When the light is on this 'neutral' becomes live and...

I couldn't manage without mine now, but I didn't pay the £8.99 from Screwfix. JTF sell them for £3!!! Bargain

Simple... At the master connect the following Red to Live Blue to Load or wavy Yellow to S At the Slave... Live - Red from three core + Red from Twin to ceiling rose Load - Blue from three core + Black from Twin to ceiling rose S - Yellow from master

Now doesn't that feel better.... :lol:

However Series actually means each bulb in turn, i.e. phase--->lamp--->lamp--->lamp--->Neutral. You're thinking Parallel. Phase ---------------------------------- |lamp |lamp |lamp Neutral---------------------------------

To me it sounds as though you're describing the condensate drain. If it's been happening any time you use HW or CH and you have never needed to re-pressurise the system. I'm not a plumber but shouldn't a condensate drain be directed into a soil stack or a soakaway??

Curve I think the OP did say that the supply is coming from a standard 13a plug so overloading the cable is not really an issue (unless the universal replacement fuse has been used i.e. a nail!) The setup isn't ideal, but again not dangerous provided the cable to the shed has sufficient...

Hi, I've just had BG Homecare out cuz of no hot water and he's refurbished the diverter valve. Now hot water does work, but I'm convinced it isn't as hot as it used to be. Also the heating is turned off but the rads still get hot when I have hot taps running for a while. Does this...

Chrism2 how can you make such a harsh judgmental statement when you clearly state yourself that you are not an expert and have no clear knowledge of the situation. In a lot of cases a built-in single oven is quite capable of being supplied by a standard 13A plug top. This is pretty standard...

Ok to patch a POTS line to a Cat5 structured cabling system you use the 1st two pairs on the Cat 5 cable, These are specifically pins 4&5 and 1&2 4&5 should correspond to Blue/White, White/Blue respectively 1&2 should correspond to Orange/White, White/Orange respectively (These are the...

Hi Keith, Have you got a job lot of 6mm T&E? You seem to want to use it everywhere! Ok, from the CU, you should use 3 core SWA (armoured cable) for the underground run; it would be much easier than trying to run sealed conduit. Put it on a 32A MCB (there's a debate whether or not it...

Anybody......

Hi, I want to insulate the inside of my roof under the roof tiles so I can board oyut the loft for storage and not have the loft at sub-zero temperatures! At the moment the house has no ventilation (that I can see), no ridge vents, no soffit vents etc. Am I correct in assuming I will...

The way you have it wired is correct. To override the light simply interupt the phase for a brief time (1 sec) i.e. switch it off and on. The PIR has solid state circuitry that "detects" the interuption of the supply and latches the relay on. Hope this helps.

So is it just coincidence that this happened after draining system?

Thanks for your reply, is it possible that draining the system to change the rad showed this problem up, or made it worse? I take it that to replace this it is take the diverter valve out and then the number of screws on the circly thingy hold the diaphram in place?
