You can do it with thermofusion or threaded. Nowadays the best thing is plastic, there are double and triple layers, different brands all good (or almost all)

I add an attachment so you have an idea of how it is mounted, no matter the brand, in general they all connect the same. The only thing that can vary is the entry or exit of the water, which in some cases can vary. Respect the placement of the relief valve.
