Review: Foarte important într-o instalație - Excelentă treabă
Review: Solid valve, no leaks ! - Just the job ! After silly quotes from plumbers, had a go myself at work, worked a treat. Just remember to de-bur your cuts and clean with wire wool. I used a flat file for the ends, and a small round file for the insides of the pipe. The key is not too overtighten the nuts, hand tighten & then 2 quarter turns with your spanner and boom, your good to go.!!
