"Valve failed in service after 2 months. Wouldn't expect that from a Pegler valve, I'd paid more for a so called reliable named brand. The wedge had twisted in the gate and hence wouldn't close properly. Not Screwfix's fault but a pain having to drain the system, remove the valve and fit a replacement valve. See how long this one lasts. (the valve is operated regularly so hadn't become stiff due to scale etc)"
