## Description

Product Description

Review: Good fit, nice quality, works - Nice little check / backflow valve. Easy to fit with a 19mm spanner, washer is substantial. Using on a hot low pressure feed to prevent cold high pressure return from a mixer tap, and is perfect for the job. No leakage, easy fit with washer (provided). I think that would have been enough but I did add a little PTFE tape (not provided) as a backup.
