Re: Help needed to understand the purpose of another pipe and valve for expansion tan
My guess would be the valve was thrown in for a power flush. coupled with push fit 22mm stop end on vent pipe seals the system temporarily for flushing. not a great idea to leave the valve attached just in case somebody decides to close it off though...doh!
