Weeping radiator bleed valve/stop


T

Tony

I'm having a problem with many of the radiators in the house weeping from
the beed valve threads. I don't know if its an age thing but they are coming
up to 15 years old now. I've tried to buy new fibre washers for them but I
just can't get any from any DIY store or plumbers merchants. Are they a
thing you can buy? they seem to be just over 22mm. Can you buy a new
valve/stop? I tried packing the treads with PTFE tape but that was no good.

Has anyone a solution to this problem?

Thanks,

Tony

Replace the valve with a new one...

Simple enough, You will need a big allen key (like that shown on the
page above) to remove and insert the body of the valve into the radiator.

Which BES product on that page are you referring to - bearing in mind that
the OP has a problem with the *bleed* valve, not with the entry and exit
valves. [I've never seen a bleed valve which has to be fitted using a large
allen key!]

Funnily enough, I was in B&Q this morning getting some cheap hose (to
drain the CH!) when I saw such large Allen keys in the plumbing section.
And it sad "for fitting bleed valves" or some such. I came back and
looked; it's clear that the blind plug at the other end of the radiator
is in fact fitted using such a key. I wonder if, after extraction of the
bleed valve shaft, there is in fact a hex socket in the bleed valve
too..

Aren't they adapted to a square end?

Is it possible that the original poster has the self venting bleed valves
which do have a sort of fibre washer that swells when wet to seal off the
water. When it dries it shrinks to let out the air?

Most bleed valves are just a pointed screw that fits into a tapered hole. No
washer - metal to metal.

Just to clarify my original post, if possible, while not being sure of the
exact terminology.

The problem relates to the bleed tap? / blanks at the top of the radiator.

Yes, I would be able to get them off with any number of tools. My problem is
how do I stop the weeeping thats started to affect them?

I assume the fibre washers are breaking down but havn't been able to buy any
that fit.

Would that the problem be fixed by new fibre washers or should I be looking
at sealing the threads in some other way?

Thanks again for your help.

Tony.

Hi,

Try <www.bes.ltd.uk> part nos
7578 <http://www.bes.ltd.uk/products/108.asp>
12611 <http://www.bes.ltd.uk/products/094.asp>

or a very good local plumbers merchant might have these.

A smidgeon of sealer on a new washer would be a good belt and braces
measure.

cheers,
Pete.
