Thanks all :)

Thanks, anyone got any suggestions regarding the auto top up valve?

Have tried thermal imaging, moisture detection, gas detection, none highlight the leak or even any possible locations unfortunately.

I'm pretty certain it's under the screed but leak detection cannot locate it with any of the gizmos. It holds over 3bar of gas pressure when cold. Plus the system holds pressure when I isolate the downstairs rads using a loop I had a plumber install which means only the upstairs rads are...

Hi Can anyone suggest a check value or similar that I can put in-line with my filler loop to allow me to leave the filler loop tap open and have the valve open and begin topping up the system automatically when the system pressure drops below 1bar and shut when it reaches 1bar? I'm in the...

Thanks - that makes sense.

Thanks - do you know if the CH and HW are separate systems within a typical boiler? i.e. is the system used to heat the hot water discrete from that used to heat the rads? Trying to get my head around why the system can maintain 1 bar pressure in the system for months whilst heating water...

Hi I have a 2 year old (non-combi) boiler in a 50 yr old house with concrete floors downstairs. The system had a leak in one of the heating system pipes feeding the downstairs rads (under the slab) which was diagnosed and fixed by trace and access guys and the system tested clear of leaks...

Just found out from another thread that the BG engineer missed that I have a magnetic system filter fitted. It's marked as "not fitted" on the service sheet. Alternate quote from a less extortionate RGI seems the practical way forwards. Thanks all

Great, thanks!

Can anyone tell me if the red cylinder in the attached photo is a magnetic system filter? It is labelled as a MagnaClean professional.

Flue emerges at 45degrees from under water tank then goes straight up & out through roof.

If the extra bracket goes at the opposite end of the flue to the existing bracket, no If it goes mid-length, a 45cm strut would be needed from an adjacent piece of existing roof structure. Would take about 30mins to measure, cut by hand, screw to existing and mount bracket. Quote makes no...

HomeCare is just an insurance police really (against boiler going bang and getting expensive). BG quoted 2.5 hours and £235 to fit said single bracket - Only materials quoted are the flue bracket. Nothing else. if they'd quoted for 1hour I probably would not have questioned it, but 2.5...

I've signed up for British Gas HomeCare and their engineer recently performed the initial service. He stated that due to new regulations, my flue (in the loft) required two brackets, but only had one. Anyone know what regs he was referring to? Is this just speculative nonsense so that BG...

Hi Is there a rule of thumb that relates to wetroom shower screens and how big they should be in order to minimise the spray that gets beyond it? My example - I have a raised wetroom floor kit (900 wide and 1800 long) that has walls on the left and in front (assuming you are facing the...

I have a cupboard built under my main staircase that I'd like to remove to open up the space under the stairs. Do typical under-stair cupboards provide any structural integrity to standard staircases?

I'm having to bleed air out of one of my downstairs radiators every couple of weeks as the radiator is only getting hot up to about half way. I then have to refill the system to top up the water in the central heading system. It's only this one radiator that needs bleeding, the rest are...

The cause looks to have been two fold: The Thermostatic cartridge is leaking where the grey temp control piece meets the main black body of the cartridge - this leak was letting water run straight down over the on-off controls. Removing the cartridge showed the main problem - the filter was...

Thanks for the pointers all. Time to take it to bits...
