Just changed mine on my oil fired boiler a month ago bc the interior seal leaked and the whole thing filled with water.
It seems like a great idea bc I hate the pump noise, but the practicality of installing and it working as suggested it is a bit confusing.
Just hook it up with a "T" fitting anywhere on the water line after the pump?
