Our existing water supply is lead. I intend on getting it all replaced by NIW once we have the new build complete. But in the mean time I need to cut the pipe at the boundary and fit a temporary tap so we can finish the demolition of the existing house.

 

I've measured it, and varies from 29mm to 32mm.... So it's either 9lb, 11lb or even 12lb!

 

What's my best option, a universal coupler like this? Don't care it it's going to 32mm or 25mm PE.

Both of those look good, maybe get both and see which one fits the best when you do the job.
