That sounds very interesting. How do I know from the packaging what is a master or slave dimmer?

I want to fit 2 x 2 gang dimmer switches in my house (so that lights upstairs and downstairs can be controlled). Is it possible to fit 2 dimmer switches on one circuit? I was advised by the lighting guy at B&Q that you can't do this- you can only have 1 x 2 gang dimmer and 1 x 2 gang switch...

Unfortunately it does have one. I guess maybe the sensor isn't working anymore?

Thanks for that information. I did check the plastic fittings and they seemed to be in place although I didn't chance taking the radiator off as it's huge. Oddly enough the clicking has stopped but I have noticed that there is a slight whistle coming from the TRV. When I turn it slightly it...

Can anoyone shed some light on a problem that's been driving me mad recently. For the last few weeks the radiator in my bedroom has started clicking in the morning when it comes on (and the evening but it's not a problem at that time of day). It clicks about once every 3 seconds for 4-5 minutes...

It's not that it took me a year to find out the pressure and the flow rate but I decided to look at my options again after getting planning permission for the extension. The DS rep put me in touch with a local plumber for the accumulator quote. I had been told by another plumber that the...

For anyone interested I never managed to 'fix' my water pressure issue with the megaflo but i did manage to find out the following: Water pressure is 2.7 bar Flow rate is 14 litres a minute This poor flow rate couple with a system that isn't balanced has meant that I've got a bit of a...

Hello everyone. It seems that I have created a monster through my original post! :evil: I want to thank everyone for their help but the I now have the answer to my poor flow rate and it's because my pipes were plumbed in incorrectly. After getting an excellent plumber in (not those cowboys...

Hey Chris He did mention that he was the only engineer that I would ever see regnerate the air gap that way. He didn't even try it the 'normal' way and instead hooked up the house to an outlet at the bottom of the megaflow, shut off the cold feed, opened the lower hot tap and then then siphon...

Unfortunately the pressure is still unknown. Whilst the plumber did fit the disharge pipe correctly he did not bring a pressure gauge. You're right they are useless the pair of them although I have to point out that the shower seems to be more powerful now the air gap has been regenerated...

OK. So the megaflow engineer came back and the dripping was caused by the air gap (or lack of it). Either way he regenerated it slightly differently to the way they tell you to do it (using a hose) and it gurgled for a few minutes. Hopefully that's all back to normal now. I was also able to...

Cool. Thanks for that. Megaflow did mention that one of the valves might be blocked/broken or leaking (there has been alot of dust and debris in the room) so when the engineer comes he'll be looking into that. I'll also have a list of other questions to ask him (and the plumber) when they...

Hey Chris I followed the instructions to the word on the side of the megaflow- the only difference in them vs what you'vw written is that I turned the cold off at the mains. I then opened the kitchen tap (lowest) and the water drained out pretty quickly (first a flow then a dribble). After...

Another joyous weekend! I've discovered that the water leaking through the tundish into the discharge pipe has caused a damp patch in the room downstairs (2 weeks after replastering and repainting the room). It turns out that the discharge pipe didn't exit the house enough and so leaked straight...

The plumber definitely is qualified to fit megaflows- I saw the ID and verified it. The megaflow engineer also took a look at the system and said that it all looked to be OK other than not being balanced. He did mention that the pressue relief valve should be in a different position to where...

So after waiting in all day for the plumbers not to turn up I did my nut and they sent their trainee to look at the problem. Apparently it's all down to my current pipework and there's not much I can do about that without ripping up half the floors in the house. The only thing that could be...

Ugh- this seems to be opening up a huge can of worms. What is the easiest way to measure your mains pressure? Can I call Thames water and ask them? I asked my neighbour the other day and he seemed to think the pressure was around 2.7 bar. The investigation continues....

Unfortunately no stately home although I'm hoping that when the system is balanced it will all be as it should be!

Hi Guys I've just had the Megaflo engineer around and found out the problem. Basically the system is unbalanced (as pointed out Fitz1). The plumber teed off before the cold water combination valve and is only balancing the hot water and not the cold main before the megaflo! That accounts for...

Guys- Many thanks for your responses (especially the banter between you some of you). From what I've read it appears that it's normal to get less pressure upstairs than downstairs and that my megaflow is operating very much on the minimum requirements. The plumbers did measure the flow...
