microbore

As part of an ensuite refurb, I need to move the pipework to a towel rail - currently 10 mm plastic. This will mean channelling the wall again and obviously I don’t want to go to deep on this. Don’t like the idea of putting a plastic fitting in the channelled slot and so my initial thoughts were...

Hi All, The hours has a fairly modern (last 10 years) heating system, a number of radiators upstairs are cold (they were not great last year, but the year before they were fine). I have taken them off the wall and flushed them, but there appears to be a blockage somewhere. I believe there was...

Hi all, I moved in to a 90s house recently and want to start doing some decorating etc. The house has microbore piping to the radiators and it is not something that I know anything about really. Through my father in law (who knows much more about plumbing than me) and a bit of googling, I...

Hi. I'm thinking of doubling up an old radiator. Thing is the inlet and outlet pipes as the radiator will stand off the wall by double the current amount. I have 10 mm microbore copper. Now it's standing off ~40 mm and I need to go to 83 mm. Also the radiator can be dropped by 50 mm to fit in...

I have recently moved house and would like to move a radiator from a side wall, to one below the window as is more pleasing to the eye. I understand why it was not placed under the window, as my house is old and has concrete flooring so would be difficult when it comes to the pipework...

We had a new boiler (ideal Max 24) installed in April. Long story short, house is 20 years old and pipes are microbore copper 8mm. We have no heating or hotwater. New boiler has never worked great. Had power flush, new pump, new divertor and ideal engineer to make sure boiler was not faulty...

I have to fix a radiator or towel rail radiator in a bathroom as the radiator is missing. The old connection has been left with only a twin entry valve. Can I install a normal double radiator ( 40 cm width) by connecting one end with the Twin entry valve and cap off the other side of the...

I previously made a post here about low heat output of the boiler - this has been mostly rectified with a balance however two radiators still only get hot at the top and not at the bottom. Edit: Forgot to mention the boiler is a 26kW Viessmann Vitodens 100-W WB1B :) When the heating/hot...

Ultimate plan is to update all rads and pipework but as an immediate job I'm putting a new rad on the landing and a towel rad in bathroom which currently has no heating. Photo shows the connection to existing landing rad, would it be reasonable to remove the narrow pipe and connect new probably...

I have a faulty TRV. When the pin is fully open, it's fine. But I notice it leaks when the pin is depressed and the TRV is off. I've tried giving it a tap, wiggle, and some WD40. I'm looking to replace the TRV and re-use the nut/olive - so I can swap the TRV over without having to cut any pipe...

A microbore twin valve is a unique radiator valve that is based on a co-axial principle. It has both the feed and return pipes connected to a single unit at the bottom of one end of a radiator. The idea is simple: The feed pipe is on one connection, while the return is on the other. The...

Same as thread https://www.diynot.com/diy/threads/microbore.67541/ I have some of my radiators with microbore system and twin valves blocked. How to fix the problem? I thought the problem was with the system being full of sludge so i had a full flush done but that did not fix the problem...

Hi, the builder that built my house chose to bury the copper microcore central heating pipes directly into the plaster. Over the years the pipes have expanded and cracked the plaster. I'm now about to decorate the hall and would like to know how to hide these pipes properly. I've probably got...

Mum lives in a 3 story house. C/H has been run in plastic micro bore ( I believe 10mm ) Boiler ( Potterton suprima HE, recently serviced and informed in good order) in ground floor kitchen. Grunfloss 15/60 pump in a/cupboard on next floor up, with a large extended lounge on lower ground floor...

Hi all, I suspect I already know the answer to this, however someone might be able to offer some words of wisdom. I bought a 2 bedroom bungalow in the summer however now that its winter and the temperature has dropped that I have realised how poor the heat output from the radiators fed by...

Our house was converted from an old barn in 1986. The builder installed microbore central heating with the ground floor pipes buried in the slab. Unsurprisingly, we have just suffered a pretty major leak which drops the pressure from 2 bar to zero in 15 minutes. The walls in the area are...

Hi, recently moved house, 2 bedrooms upstairs don't have a rad fitted, I located where the manifold is upstairs , it's a 22mm pipe with end cap and 4 microbore feeding out, as there's 3 rads in use I followed the 4th to where it's capped off and plan to freeze the pipes and use it to feed a rad...
