The main stopcock in my house (22mm - under the sink) has, it seems, at some point become stiff and unusable. This original stopcock has been left "open" and a new stopcock (15mm) has been fitted with the onward connection to the 15mm copper house supply pipework being made in 15mm braided flexible hose.
Although a 22mm stopcock was the original shut-off valve, the pipework in the house was always 15mm, so I assume inserting a new 15mm stopcock will not affect the water flow. However, I assume the flexible hose will have a smaller bore than 15mm so will this affect the flow to the fittings in the house, and if so will it be significant? Do I need to have the flexible hose replaced with 15mm copper pipe? Thanks for any thoughts/comments.
