Verified Purchase(What is this?)
This review is from: Silverline MS135 Combination Stopcock Key, 1000 mm (Tools & Hardware)
We have a stop cock in our kitchen which has seized up, and the last plumber who came had to use one of these outside, the mains system in the front, and so advised us to have one in case we ever need to turn the water off. Have not had to use it yet, thank goodness, but feel happier now we have this in the house.
