Full bore or Lever valve?

[Justice League]

I am thinking of making some improvements. I want to replace the existing isolating / stop valves which I think are just standard ones to full bore valves. However for ease of use I would like to have valves with a lever but I can't seem to find a full bore lever valve.

On screwfix I see the following.

But the following it says its a ball valve.

Which is better for isolating the supply - will be in bathroom.

Full bore but on cylinders eg feeds levers as in an emergency they don’t require tools

Did you read it properly/fully?

Butterfly handle iso ball valves will do if you want easier use and you can't use a slotted iso ball valve as you listed.

Sorry but my explanation was a bit poor. The existing stop valves I want to replace are the ones connected to the sink and bath.

So copper pipes currently terminates in a isolating valve that requires a screw to operate. So an isolating valve that is full bore, has a lever and can connect to the sink and bath flexible tails.

I'm very partial to a butterfly. Sometimes there isn't room for a lever.

Providing you have the room use butterfly full bore valves if not then screwdriver operated full bore would be your next choice , bes online or any local plumbing merchant should have them. Kop

That looks perfect. Can a sink / bath tail be connected to that?

The reason I am looking for a flat face isolating connector is from this video. 1m 10s in but then he says not that he has had leaks from a standard fitting - so not sure.

 

[gmartine]

If they're not leaking or causing a major inconvenience just leave well alone unless you want to make work for yourself. By all means change them out when it's convenient ie when you're doing other DIY in those areas or the system is off/drained down.

Do these come with a compression fitting on one end and a flat connector on the other end to attach basin taps, toilet inlet valves.

I thought I could connect these to flexi tails.
Or do I need another connector?

You can stick a flexi straight on. Just slightly more than hand tight. You can get "flat faced" specially for flexi but not sure they come as a butterfly.

I have a 22mm bath filler tap and 15mm pipes. So I need a flexi that will connect from the bath tap to an isolation valve that is full bore and if possivle lever - but screw operation is acceptable.

But it doesn't say they are full bore.

Am I correct in thinking that isolation valves should be somehwere on the pipe and that service valves are on the end of the pipe where the flexi tails are?

Any valve is in essence a service valve.

I always use full bore lever valves, there is rarely a situation where it can’t fit. If needed, cut down the handle or put it in the vise and bend it.

If you’re gonna attach a rubber flexi to it, I always give the compression end a slight file to flatten it.
