Durability of the solar panels/collectors in Drain Back Solar Hot Water Systems

There are lots of ifs to consider before ruling out a vacuum breaker or pressure relief mechanism up high. Whether or not you can tolerate the sound of your drain pipe gurgling slowly is one decision only you can make. Even if you design the system so it should never stagnate, it still might. If there is no pressure relief installed up high, any steam generated will clear your drain for you quickly and violently.
