I installed a Weil McLain CGA2 and created 1 challenge and have a couple of other questions. 1. I created a "manifold" of sorts to distribute to the zone valves. If either of the bottom 2 zones are open, the top gets no heat... Why? Do I need to add balancing valves? 2. I didn't think...

I installed a Takagi T-H3-DV-N and so far we love it. Is there any harm in letting the condensate drain into my sump crock? How acidic is it? What other options might I have? Thanks, Brad

I am installing a bathroom in the basement and using a Saniaccess 3 for a sink, shower, and toilet. I had intended to use a "cheater vent" for each fixture and the the pump. Upon reading the directions I see that an AAV is not allowed for the pump. This makes sense once I think about the...
