Thanks tony. Didn't install it myself but like to understand things when they are done. Still dont understand what two two port valves will do that the 3 port wouldn't do?

My plumber recently installed an Ariston presurised indirect cylinder for me. When he came to do it he replaced a 3 way valve (think he called this a y plan) with two 2 way vavles, one that came with the system and one that I bought. After he had finished I sat down and tried to understand why...
