microbore manifold

[pincher]

Hello all,I have a microbore heating system(ahhhhh)Is it poss or safe to put inline taps coming out of the manifolds on the inlet and outlet.The reason behind this is:-i want to renew pipe work and rads over a period of time,and this way i though i could isolate one rad at a time and work on the pipework while rest of rads still work and keep me warm and cosy while working.and not have to keep re-drainging the sytem.

Many thanks

Yes, but you would have to choose the isolating valves carefully. Compression joints on microbore are not as reliable as on normal tube (microbore is softer) and some cheap valves tend to leak around the spindle seals.

many thanks,any ideas as to what ones and where to get some isolating valves please.I only want to do this once with no leaks pref lol


Thanks

Try BES.

Im off to B & Q Warehouse today,wife is dragging me up there to look at sink units,more work lol,will they have any HALF descent isolating valves there?????

Dyou happen to know the thread size if they will screw into the manifold,or will it have to be inline??


Thanks again

Well I really ought to know exactly which manifold you have and it's thread size, even though you haven't told us, but I'm afraid my psychic powers are a bit feeble this time of the morning.

lol,wish i could tell you,no name on it all i know is it has 22mm in-6 outlets at 8mm (3 on each side)and 22mm out at the end.

and bs864 on it


Thanks Chris

Ah..wait...my powers are coming back....I think it might be 1/4" female thread on the manifold.....but I can't see anything suitable in B&Q.....now it's fading again.......

 

[pincher]

Lol thanks Chris,your post def put a smile on my face,and thats not easy this time of morning on a sunday lol


do they have a B&Q in Cuba lol

 

[chrishutt]

....now it's clearer...I was wrong, it's not 1/4" (told you my powers are feeble)......the threads are slghtly larger (10mm) or smaller (8mm)......can't see exactly what threads....something very unusual.....I can see something written on the manifold packaging....W E D N E S B U R Y - M I C R A F O L D.....it's very old........ now it's gone again....

 

[pincher]

is it poss the threads on the manifold could be the same size as the fitting on the microbore(8mm)that screws into the bottom of the lock shield on the rad???

Now you've got me thinking about it, I don't think it can be a Wednesbury Micrafold with 6 connections - I think they had 8 or 12 connections (for 4 or 6 rads). Are any connections blanked off? As for the rad valve connection, you'll just have to see if the threads match - quite possible if valves and manifold are of the same manufacture.

Edit - I wrote that before seeing kev's pic. Yes, it could be the Yorkshire one, in which case it will be one of a pair!

 

[pincher]

Lol thats the one kev.chris kev has put a pic on.thats identical as ive got.


I have 2 of those,one for the inlet on the rads and one for the return.if poss i would be nice to screw isolating valves straight into it and microbore into that instead of cutting the pipe work



Thanks

 

[chrishutt]

You'll just have to undo one to check the thread, unless kev or someone happens to know the manifold - I didn't think they made the anymore. You could always ask Yorkshire.

I have 2 of those

If you'd said that at the beginning I wouldn't have wittered on about Wednesbury - now my psychic powers are exposed as a fraud!
