microbore help

[doitall]

Microbore relies on high velocity in the pipework, throttling the the lockshield valve is the opposite to what you should be doing, open then up and get some circulation going.

A good flush through each valve would be a good idea.

thanks thus far - to add - system is getting warm in some rads = particularly upstairs - I am sure its 10mm plastic mostly - did add a metallic one when convering garage around 5 yrs ago (house was 15 months old then and system worked fine) - Property is 6.5 yrs old - will my builder still sort the issue ? JS Bloor - Bottesford Greenacres buils project by the way.

Lockshield covers ?? - they on top at one end of rad ? Surely the engineer would have looked at most of these options ?

One end of the rad will have a TRV - the one you adjust for heat. The other will have a simple valve with a plastic cover that does nothing. Remove this cover and use a pair of pliers or adjustable spanner to open up the valve.

With BG engineers, assume nothing - you get good ones and others that aren't any good. They may try to sell you a "powerflush" to resolve the issue, and be more expensive than most independent traders. Given that we recommend you adjust the lockshield valves and add some cleanser to the system as a first way forward - this will cost you less than £20 and may sort it out, saving you quite a few bob.

will give those a go - thanks again - Incidently where do I get into the system to add the cleanser - and what do you recommend adding (and volume ratio ?) - cheers - my weekend is getting a little better now

We await, with eagerness, the next obvious question

fill loop View media item 11214 theres an adaptor with the can

presumably I shut off the system ? - I know where to loop is - does it going boiler end away or other end towards boiler ? -betcha you lot love us virgins - lol - I am a craftsman by trade twice removed (No really I once was a plater/boilmaker)

 

[kevplumb]

towards the boiler usually the larger of the pipes the loop is connected to

And do i need to drain system or anything

ps Get PENFOLD on the job

 

[dextrous]

It's more to do with how you get it out again

And do i need to drain system or anything

And, so the question is........

no you might have to bleed a rad into a jug afterwards if it goes up to high tho

easy enough done

 

[duffyster]

pretty sure the system will cope with the volume - its never too high

the grins must imply I need to the drain the system - or catch the crap that may (hopefully) come free - I am sure that the cleaner wont just dissolve/consume the crud - a hose on the last radiator itno the garden ? - and before you ask - i havent a clue which is the last rad
