Push fit isolation valve onto copper pipe?

[bosco72]

Hello, cheers in advance for any help, I want to remove a bathroom and eventually replace it, but I was wondering could I use a push fit isolation valves as a temp cap onto copper pipes?

Yes

What could I do with the radiator? As I believe they are not suitable for central heating.

If it's for a temporary capping off why not use a cap?

And, you can use pushfit isos on CH, just not the plastic ones.

Leave the rad valves on.

Do I need to drain the system off? I'm a complete noob when it comes to plumbing, I plan to have a professional replace the bathroom. I want to do as much as possible to keep costs down.

Cheers.

If your talking about draining the heating system then no you don't, Just turn both valves off either side of the radiator and crack one of the union nuts drain the rad and remove. As for the hot and cold we need to know what type of system you have.

Do you mean what type of boiler? It's a Worcester combi boiler?

 

[Armo74]

Depends really on how many isolation valves are in place serving each appliance. If there is none then you can turn the main stopcock off that will stop your hot and cold coming out and just drain the system from your kitchen tap(s). Or you could wait for the proffesional

I like the idea of shutting it off and simply removing the rad, is there anything I should watch out for?

 

[bosco72]

Just the rad valves

 

[Armo74]

The only thing really is if one of the valves is a thermostatic one then you could do with removing the head and putting a cap in place of it just incase the temperature drops and the valve opens, do that before you remove the rad. Or you can cap the valve off on the part where the rad tail usually goes.

 

[bosco72]

Yes

Just to double check, I can use plastic pushfit isolation valves on copper pipes and then work with plastic after that?

There is no thermostat control on the rad, is that the same thing?

Just close both valves drain down rad and remove then.
Don't forget the inserts for the plastic pipe if you intend on using it
