### ⭐⭐⭐⭐⭐ Love JG Speedfit. Used as isolator in my camper pressurised water systems
*by T***S on 19 August 2025*

Positive shut off tap. Fits well and easily with no leaks. I have fitted it near the pump using 12mm JG Speedfit pipes, as an isolator in the pressure water system. It allows me to shut off in the event of a leak downstream of my pump.
