Hopefully someone can give me some advise.
Basically i have treated my system with x400 and now drained it twice and added x100. The overflow in the F E still flows when pump is put on number 3 also i have noticed when heating is turned off it squirts out a little while shutting down . My system is a back boiler open vented .
Any ideas?
