will this affect the performance

[grajam247]

I am in the process of renovating the bathroom in my rental property, and need to fit a new shower unit.

Rather than pulling the tiles off the wall, i am trying to feed the new supply tails through an adjacent stud wall.

My question is that by fitting two short lengths(700mm) of 10mm pipe, will this affect performance of the shower.

Shower is a mira themostatic, and boiler is a ecotec831

Thank you in advance

S/be ok as you've HW at mains pressure. 15mm easier to work with as it's half hard.
