Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws

You need to find out of your cylinder stat is “ getting a live “ , has anybody knocked it , is it an unvented cylinder?


How can it be unvented cylinder if there is only 3 port valve. Correct me if am wrong on that if it’s unvented cylinder then there must be a two zone valve also after the 3 port Y plan.
