Speedfit 10mm pipe

[mikebh50]

Hi

looking to fit some isolators to our bathroom sinks which are plumbed in with the above . want to get some 15mm isolators so that one end can go straight on to pipes from the tap so my question is do I need to put the inserts in the tube before I fit a reducer or are they only required if you use a brass fitting rather than a push fit one as really confused with the amount of different fittings.

Thanks
mike

Always use the inserts weather you are joining the speedfit pipe using push fit of compression ( if you are using a compression fitting it is advisable to use the normal inserts rather than the superseal type)
