But if I can rephrase/refocus....is there a check valve in these lower reservior tubes so that they only draw form the reservior?
If not, what is the thinking between the larger lower and upper (smaller) pipes?
Are the upper ones in case of a "steam/boiling" event - hence they come from the top of the system, but most of the time the lower pipes draw and suck any 4% system expansion.
(PS 4% expansion from 10L = 400mls)
Yes, in the little tank design, there is the larger tube connected back to the original tee. It allows you to see the pump working, and a convenient place to check level, and fill. A lot of us use a different mixture in this system for maximum cooling capability. If you live where it freezes, you would change the mixture from summer to winter. You're going to need a place to fill it up right? There is no check valve in the system, the system is simply based on the elevation of the water in the system. The cap to the little tank has a small hole (OEM)in it, so there is zero pressure in the system now. I remember when I was trying to figure this system out, I was scratching my head, but when I finally got it I realized how simple it really is.
