Q The Screwfix catalog (page 286) shows 3 similar looking valves, with same stated spec but different coloured handles (yellow, red & blue). Also looked at a screwfix competing website which had them with/without chrome plating.
What's the difference & are there any limitations as to use for water - eg pressure, temperature? What is the PN16 spec that screwfix state?
The screwfix ones appear to be no-name, Are they up to the same standard as the Pegler brand one I bought locally at over twice the price?
