### ⭐⭐⭐⭐⭐ Just the job
*by C***S on 21 September 2025*

Fitted a like for like shower in after replacing an old isolation valve, first thing I found was the shower water pressure low, so bought this large bore isolation valve for easy operation with fitted level. And the water pressure to the shower was much much better, all you've got to watch is it's slightly longer if your swapping out an existing old isolation valve. But I would buy this unit again.
