1/2" BSP hose to isolating valve? | DIYnot Forums
2019/9/3· Can I connect a 1/2" BSP fitting on a flexible hose (for a cistern) directly to an isolation valve that was connected to a fixed pipe via a 15mm compression fitting? Will it work without leaks/last? I know I could do it by leaving a short length of 15mm pipe in place and using a 15mm to 1/2" hose, but there''s not a lot of room to maneuver!
