Now I'm set back a few more weeks, :headwallblue:
Tank runs fine but just too loud for my living room.
Can get the tank to run pretty quietly but I have to "tune" the drain with a ball valve and that's not something I'm comfortable with on only drain.
I cut off all the teeth on my box to help with linear flow, it did a little and was able to open drain a tad more. Still not where I wan to be.
So I ordered a new overflow box today, should have 20 inches of linear flow as opposed to the 10 I have now........we will see if that works if not will drill another hole for dry emergency drain and "tune" the main drain.
