Conex iso valves

[Mgrant]

Are conex iso valves usually pretty reliable? I.e they won't leak from the slotted section on the valve years later if turned off and on for maintaince work.

Conex are a well known brand but if you want the best fit genuine Ball-o-fix valves or if space permits fit lever valves....regards Turnpin:biggrin:

another vote for level valves if you have the space

and find the full bore iso valves better (havent had a problem with one leaking yet)

Thanks its a conex valve thats already in place that's at question. Just heard a few stories of iso valves leaking when turned off and on again.

if it does just change it

As we know, the small bore standard cheap isolating valves are useless - breaking inside or leaking, plus they restrict flow.
The full flow versions are a lot better. If you look carefully inside them at the ball, you will see a white seal. That is a hard ptfe seal same as in a lever valve and should mean they are as good as a lever valve and hopefully won't leak. The cheap small bore isos only use a rubber seal.

So the conex valve could give me issues?

Not to say they would but if you have an oppertunity to change them now then I personally would....regards Turnpin:biggrin:

As above, ^^ decent reliable valves make a future job easy.
I use full flow isolating valves on nearly all places that just require a slim isolating valve for occasional use, including toilets. For elsewhere on things that need just a hand turn valve, I use lever valves on all hot pipes, and most cold pipes and sometimes stopcocks on cold supplies and obviously on mains cold coming into buildings.
For where I need a small lever valve, but a quality one, like inline to a washing machine or on a filling loop to guarantee it lasts, I use the 15mm gas valve small lever valve. They might cost a couple of pounds extra, but well worth it.

I have actually run down my stock of standard ballo's and only using full-bore now; bit stiff to begin with but have soooooo much more confidence in them!

Thanks are boundary stop taps usualu ok to turn off and on is an old one wont turn by hand but a stop tap key will likely do it

Need a good screwdriver and work them a bit

They are very tight, but I guess that proves they are same as lever valves, with the ptfe seal nice and tight.
